I suppose that the facts in this article are true, but are we really going to phase out gas stoves in all households and businesses? In our lifetimes?

Lol! I’ll keep my gas range. That being said, mine is clean and flames are always normal because I don’t let things boil over into the orifices to create a dirty flame. If they want to say houses are too tight to use a gas range, then the HVAC professional didn’t add the proper fresh air to the HVAC system. Most older homes ventilate themselves enough though leaky windows and doors, etc. This is another one of those things where someone else benefits from trying to protect people from themselves.

Choosing to have gas appliances in your home is not just about the monthly cost or the obvious dangers they present to your immediate home.
Gas explodes. Not just in your home where just a small pin hole leak can accumulate and cause your home to explode. Also the pipes leading up to your house where they can rust and leak. I've seen this several times and had to call for emergency service from the gas company. Also the large laterals in the street and the big mains that deliver gas to communities. Then there is all the work that goes into digging the ground to install these dangerous pipelines.
Gas cooking appliances can't easily be moved around like a electric toaster oven or cook plate.
Most people already have electric. Not every body has gas or propane. Electric will continue to decrease in cost as the networks become more stable with the new Tesla battery back up systems that are already in use. Plus, if you install your own solar system you can make your own FREE electric.
Solar panels don't explode.
Spend money on insulating your home. It's cheap. You can do it yourself yourself if you want.

I have a new gas stove and I swear to keep her working cleanly, safely and efficiently... I love cooking with my gas enough that I would never want to see it taken away...
And as for moving, it isn’t something I would frequently do no matter what the fuel type for my stove should be... I’m sure there are equally dangerous radiation-like things those electric ranges out there could also be polluting air and endangering lives with as well... — Dave |

Gas ranges are much dirtier tan any other gas appliance used in the home and it is the only one that is not required to be vented outside.
There is NO such thing as a properly adjusted gas range, when you boil a large pot of water on a gas cook-top if the flame touches the colder kettle it produces a large amount of CO, there is nothing you can do to reduce this.
Likewise turning on a gas oven or broiler produces large amounts of CO because the flame is burning against cold metal, this effect does subside somewhat as the metal gets hotter but preheating a gas oven in an average kitchen will quickly get you a 35 PPM reading of CO.
Gas dryers are not much of a problem, I can run a gas dryer unvented in the same shop area in my basement unvented for an hour drying a large load of clothing and get no reading on our CO monitor, this is the same monitor that will quickly give a reading of around 35 PPM when a preheat a gas oven to 350F in the same shop space. Gas dryers of corse are usually vented out doors because of all the lint and heat and humidity they produce.
The very least that needs to be done about this is to have a requirement that ventilation equipment be installed in kitchens that vents OUTSIDE, These fans should also have sensors that will turn them on automatically when they detect CO and possibility other pollutants.

The article argues against gas stoves/appliances, but these arguments would only be applied (practically) to new installations. The cost of replacing gas with electric would be prohibitive, considering the existing risk of keeping the gas.
In my situation, an old, 125-year-old house equipped with gas, and electrical service not as updated as in a modern house, the stove is gas. In fact, it is a gas-and-gas stove, heating part of the house. I have 4 other direct-vent gas fireplaces throughout the 2-story house. The house is insulated, with Pella windows, so it is not "drafty", but I'm sure that air does circulate from outside. The stove is vented up the chimney (B-vent), which is located in the center of the house. What would my options be, if I had wanted to eliminate the health risks of gas? 1. Buy a new gas stove, place it on an exterior wall, with a range hood venting outdoors. Then I would need to replace the heater with another direct-vent fireplace (these cost north of $3,000). 2. Keep the present setup, install a range hood, and run the ductwork across the ceiling to an exterior wall, making the kitchen look like a factory. 3. Ditch the gas stove, and wire for electricity. Even more thousands for rewiring and replacement of heater. In these possibilities, the cost/benefit does not outweigh my risk. I have lived with gas for 65 years. I'm comfortable with the present situation, but if I were building new, I probably would go all-electric. I have multiple CO detectors. My only concern is if and when the gas-and-gas stove becomes unrepairable. No plumbers or gas co. employees will touch it. On the other hand, if I got rid of that stove, I would not need my chimney, and I could install a cupola at the peak of the roof. |

After a few hundred thousand years of man cooking over fire one would think we have further evolved by now. But we are creatures of habit I suppose.
I can't imagine having a gas stove in a home, especially a modern home that is tight and no longer has the constant ventilation of a standing flu for the heating appliances. In a restaurant gas makes sense, high constant BTU's for low cost and there is a insane vent hood and fire suppression system. But saying this is ideal for home cooking is like saying since race car drivers use slick tires I'm going to run em on my street car. Even if it weren't for the indoor pollution and smell, I can't deal with the lack of temperature control. Odd that I've never needed a double boiler on any electric stove. But like religion, we can never convert the faithful. |

and given my choice I’ll take electric. It’s cleaner, safer and easier to control the heat.
When we bought our home over 25 years ago we were moving from a condo that had a gas dryer, gas stove, gas water heater and gas forced air heating. I was really worried that the cost for utilities was going to go thru the roof. True, electric heat does cost a little more than gas, but I have asthma and the lack of dust in the air makes the extra cost worth it. Our baseboard heaters are hydronic and very efficient.
But what I like best about all electric is cooking on an electric stove. Much cleaner more control and better baking. On my electric stove I know that I can set the control to the lowest setting, say for cooking rice, and set the timer and will have perfectly steamed rice in 18 mins. With the gas stove in our old home, 9 times out of 10 when the flame was set low enough to steam the rice and not scorch it, the flame would go out and unless I watched it like a hawk I’d come back when the timer went off to find uncooked rice. This is just one example, though small of how an electric stove performs more dependably.
Additionally, every time I used the gas oven in our old home the kitchen filled with CO vapors, because the new gas stoves are generally not vented outside. I believe this is not healthy. And the white formica countertops had to be scrubbed weekly to remove the film that covered them from the gas stove.
If people want to use gas thats their prerogative, as long as its still allowed in their jurisdiction. But really, one can adjust to anything if necessary, and sometimes can also be pleasantly surprised that the conversion from gas to electric that they dreaded turns out to be something they embrace rather than despise.

I will never give up my gas range, furnace, or fireplace! I've never had any ill effects from any of them, even when our 73 Tappan Range (she was a beauty) in our first house would trip the carbon monoxide detector..(low readings) (it only did it when it was on for long periods of time, like holidays) We have an electric stove in our summer home and it takes forever to heat up.. I couldn't imagine having to deal with that every time I wanted to cook! (I guess I'm just stubborn) and perhaps a bit crazy.. lol

None of this discussion was about home heating with gas and forcing a conversion to electric heating. It is about the indoor pollution by unvented gas ranges in kitchens. |

I’ve cooked on my niece's and her MIL’s gas stoves and it took over 30 mins to get a 6 qt. pot of water to boil.
On my GE coil top I can get 6 qts. of water to a boil in 10 mins or less. So I would have to say my experience has been electric is faster than gas.
Seems like a lot of wasted energy using gas, even if it may be slightly less expensive.
As I’ve said before, you can adjust and get used to anything with time.

"If gas was really detrimental to our health wouldn't something have been done long ago ?"
Oh gee then, I guess that's that. No need to worry. The world is perfect with the exception for those few documented problems on the big 'TV machine'.
NO.
That attitude is NOT how a society improves.
We most certainly WILL try and bring to peoples attention when there is a problem. Trying to 'hush' people from protecting other innocent humans is a DEF. NO GO! SHAME !
Ah, YES, we SH|OULD ! Who wouldn't appreciate a better, safer, more efficient society. Again, that is how the world improves. It doesn't matter what the entrenched want. |

I would expect YOU to know better than that.
You should know that gas dryer manufacturers specifically point out in their owner's manuals that the dryers MUST be vented outdoors.
That the manufacturers of vinyl dryer ducting specifically state that their product is NOT to be used with gas dryers.
That the makers of indoor dryer vent traps specifically state that their product is NOT to be used with gas dryers because of poisonous gases
Perhaps you typed that in incorrectly and meant something other? |

It's interesting talking about unvented gas ranges and their effects on indoor air quality. However, using other types of gas appliances that are installed with vents to outside should not negatively affect indoor air quality as all combustion by-products are exhausted outside.
Gas cooking appliances are the exception as they are not themselves vented outside, although you may have a hood which may be vented outside and may or may not be turned on.
As for venting a dryer indoors, this is usually not ideal (I wouldn't want to do it) due to the lint and moisture, unless you attach an additional "filter" to capture the fine lint and don't have a problem with humidity. This applies to both gas and electric vented dryers. In terms of any risk posed by venting a gas dryer indoors, this is interesting because most people believe that this is dangerous, yet they don't believe that having a gas range is dangerous. In reality, a gas dryer should burn very efficiently and always has some kind of timer to ensure it should eventually shut off. Whereas a gas cooktop can be burning far more gas than a dryer and it can be burning very inefficiently when you put cold pans on to boil, resulting in more emissions being given off into the home compared to the emissions from a gas dryer (other than what you would get anyway from an electric dryer).
The installation of gas appliances in the UK is strictly regulated in terms of who can install them, what checks have to be made after installation, the suitable location of the appliance and the provision of make up air, if the combustion is not sealed from the room air. The regulations on flues for gas appliances are strict, however, gas dryers are not required to be permanently vented outside unless required by the manufacturer, although it is highly recommended and I would imagine almost all are. Gas dryers do need to have provision for ventilation for safe operation but permanent outdoor venting requirements are the same as for electric vented dryers (recommended but not compulsory). This is because they don't pose any greater risk than a gas cooker/range/oven/hob/cooktop etc. In fact, they are likely to be far far safer.
As for cost, cooking typically accounts for only a small fraction of household energy use. In Palm Springs, electricity is very expensive and you have either a tiered or time-of-use plan. I have a tiered plan, which starts at $0.19/kWh and as you use more you then start paying $0.25 and then end up paying $0.43/kWh for the rest if you progress into the top tier. Whereas gas is less than $0.04/kWh. So the saving is clear. However I still much prefer an induction cooktop over gas. Induction can go lower and far higher than a gas burner. It responds instantly. It is far more efficient (uses less energy) and emits less heat to the room, offsetting the higher cost of electricity to some extent, but not completely. I suspect that many (most?) people would prefer induction if they tried it for a couple of months and would not want to go back to gas. |

No straw man. These things happen in the real world. No need to get your bloomers in a bunch. I don't throw pans at my stove either. Use what you like. As long as it isn't hurting others....isn't that the mantra ? |

I hate electric for stovetop cooking, like a pot starts to boil over with gas, it is stopped immediately by just turning it down and glass electric cook tops do shatter and cost ALOT to repair. But for baking an electric oven works better for me. I have propane for my range and supplemental heat and they always work just fine during a power outage. I wish I had my nieces dual-fuel Jenn-Aire.

This isn't a competition and no one's a bad or second rate person because of the appliances they have. Especially in this club.
We're all here to support each other in our appliance specific persuits, whatever they may be. There are too few of us in the world to be concerned about petty competitions and knocking off "the weaker ones" I grew up with gas appliances. Our 1960s home had a gas line installed in about 1978 and we converted from a oil furnace to gas. That's the only appliance we converted over but my parents intended to do a water heater. I used to LOVE the gas stoves because as someone else pointed out, they instantly come on and turn off. I also liked the smell too, which I find really odd. lol But they also soot your pans. I've installed several gas furnaces, water heaters, piped in and installed gas stoves, I installed (two) gas fireplaces in my second and third homes I built. In the midwest where I came from gas was, and perhaps still is, like life blood. But, we weren't told of the dangers either. Yes I have experienced gas pipes going through cement walls that were 15 years old and the lime was literally eating through the pipe to the point it was leaking gas. An emergency repair was required. Thank- god the gas company was going around with their detectors, found it, and called me. And yes, I was re-piping a stove for my former X in his 1955 house and we found that the gas meter outside was leaking. Yes, I know what it's like when the carbon monoxide detector goes off because there is a leak in the house and I couldn't smell it. Yes, I know what it's like coming home after being away for a month in winter and the house has the subtle tinge of gas because the gas connector to the furnace is leaking and required instant repair. Yes, there are numerous videos showing not only homes blowing up, but the large delivery lines exploding on security camera. And there are numerous other public incidents. When you look at the fires after earthquakes in California, many would not happen if there were no gas lines. It's absolutely stupid in an earthquake prone area where we know the ground is constantly moving, to be burying gas lines. That's just asking for a disaster. Throw in gas lines connected to a mobile home and the jostling of an earthquake is all it takes to cause a leak. Am I biased against gas? You bet I am. Especially for residential purposes. This stuff doesn't happen with Electric or Solar. CLICK HERE TO GO TO bradfordwhite's LINK

Ever see a lithium battery catch fire? It's basically out of control, cannot readily be extinguished.
Nothern California's worst wildfire was started up north of the Bay Area by arcing ELECTRIC power lines. How many died there? Ratepayers will be paying off the cost of that for decades to come. A well adjusted gas flame will burn blue and have little to no pollutant emissions. And anything that does come out can be handled by turning on the range hood fan, which nearly all homes have these days. Those that don't are likely to be older homes that are not air tight to begin with, and have enough indoor air changes naturally. Bottom line: energy storage and transmission of ANY kind is inherently unsafe. There are well known ways to prevent disasters both with gas and electricity. When these methods are allowed to lapse we get problems. |

I guess there are two kinds of gas stoves, I have never seen any soot on my pots and pans --ever!
I'm using a split system - I have a Siemen's gas cooktop over my Electrolux wall oven, I think it's the best of both worlds. |

The only time I've seen pots turn black on the bottom using gas was propane. Back in the 80's, either Discover magazine or Popular Science had an article about gas ranges and their pollutants. They also wrote about new type of burner, maybe like an inshot burner used in furnaces now, that fired below the cooktop and just sent the heat out through a ceramic distributor plate with holes in it. There was also this metal ring that would just sit on the aluminum burner and cause it to burn even cleaner. Man I love the internet....here it is. It's funny I can walk from one room to another and forget what I was going in there for but this article I found within 2 minutes because of my semi-photographic memory when it comes to pics and conversations. I haven't seen this article since I read it way back in 1984. books.google.com/booksQUESTIONMA... This post was last edited 05/14/2020 at 05:24 |

Hi Greg, thanks for posting this, I always loved PS magazine
It is interesting that when they convert the gas burner to more of a radiant burner design that it becomes so much more efficient at heating pans and releases less heat into the room, it makes it behave more like an electric element but at a lower operating cost.
My friend Tom reprinted an article from Appliance Manufacturer Magazine many years ago where Hardwick range company actually built and sold a gas range with an inferred gas top burner that also had a sensor so you could automatically control the pans temperature.
Gas ranges are not likely to go away in anyones lifetime here, BUT they need some serious redesign.
Gas ranges have gotten WORSE in energy consumption since the mid 80s in the US because the appliance manufactures lobbied the department of energy not to have any regulations on gas or electric ranges auguring that all ranges were about the same and therefor there was no point in any regulation.
So range builders started making ovens bigger, windows bigger [ many ovens doors have zero insulation in them any longer ] they started going away from well insulated Self-Cleaning ovens. And on the surface burners got much higher BTU burners and heavy cast-iron grates that all have increased energy use and pollution in the home. Many of these features have also made ranges harder to use and clean as well, but manufacturers realize that ranges are more about styling and looking professional than actually being used to cook with.
This has resulted in longer oven preheat times and broilers that do not work nearly as well. The excessively large front burners on gas ranges cause lots of burns and accidents from flames shooting out from under pans every year. I often have customers that complain about this and I put in the smaller propane orifice and drill it out to a reasonable size. The other week I converted a 17,000 BTU burner on a KM-FD range to about 12,000 BTUs for example.

I've always preferred gas for a stove top and electric for roasting and baking. We had a 1990 JennAir dual fuel range at the first home we owned, and I loved that system. The electric convection oven was brilliant at baking and roasting. We replaced it with a newer JennAir range that was all gas (Dave's decision, and he was the cook), and that thing would immediately give me breathing trouble when the oven was pre-heating. I had to exit the kitchen when the oven was in use. I hated it. Fortunately, we sold the house within a few months of buying that stove.
So, I do believe what they say about the toxic nature of cooking with gas, but I think it depends on the stove and the tuning of the burners, both on the cooktop as well as the oven. Ideally, I'd like to replace the current OTR microwave with fan that stupidly blows the exhaust out into the kitchen, and have a vent put into the original flue/chimney for a real exhaust hood system.
I agree that electric cooktops are cleaner, and I like the idea of pot and pan handles that aren't too hot to the touch, but the infinite flame adjustment and instant on/off of gas is something you just can't match with the average electric burner. |

Much value is put on the infinite control of a gas flame and instant on and off of the heat. It’s true that you need to adjust to taking into consideration of the residual heat of an electric stove top burner. However, it really take very little time to get used to this. In some ways its not different than cooking on an old fashioned wood stove in the respect of using residual heat. Its just what you get used to.

I don't know if it's true but I've heard-said that 12K BTU of cooling is needed to handle the load of a residential gas range/oven. Granny always had gas. She had a 12K window unit in the kitchen for some years. It could not handle the load when we had family gatherings or she baked batches of pastries in the summer. Kitchen temp reached very uncomfortable to near-intolerable. Later 18K and then 16K did better but the temp still increased noticeably. The parents had gas for their first three years, electric ever since. I've never had a house with gas so my only experience with it was at the grandmother's. |

That's why I have an oven outside in the screen porch. It can also go in a garage, or just outside on a table depending on where one is.
I'm using the oven roughly every other day. Nearly everything gets cooked outside of the homes thermal envelope that way all the heat, cooking smells, humidity, and any possible sooting or burning just floats away. One isn't adding to your homes Air conditioning burden and you don't have to deal with increased humidity or odors.
When the timer you've set inside goes off, just grab a mit and go retrieve the item from the oven.
Interesting enough, I've even set my oven outside a window and cooked chicken when it was 10 degrees in Minnesota. Works just as well.
Why anyone would choose to have an expensive 250 lb. block of steel stuck in their kitchen they can't move about to cook in or on when they can have a couple of small inexpensive, appliances they can easily lift, change out at will, and move to desirable locations... I have no idea.
Old habits are both a blessing and a curse especially when better technology arrives.
I got my stove top for $14 new. The inside oven I found at a resale shop for $4 unused and it only gets used for nachoes or quick warm. The one I use outside where most baking happens I paid $3 for at a pay by the pound shop and it was hardly used and needed a switch. I fixed it and it works great now. Both are full size you can get a pizza or bake a cake in them.

So has my tolerance for heat diminished so after using gas for most of my life I am more than happy to have Induction cooktop its quick easy to clean and doesn't waste heat around the sides of the pan or warm me up while stood in front of it. Not so sure about the ones under the granite top I have cracked mine with a pan from the oven so not so heat proof as they want us to believe.

The real problem with modern gas burners is that they are of the "sealed" design. This means they don't get any air flow from below, and consequently the flame blooms out much farther than in an old range. ?The modern style uses less vertical room, so the oven can be that much bigger, but it sacrifices burner performance, IMHO. Give me an old O'Keefe and Merritt or Wedgewood gas stove over a modern sealed burner contraption any day.

I do have the ability to vent the oven, but hate the ugly vent pipe.
I'm kinda with Keith though..I keep a toaster/convection oven out on a back porch, along with a bread toaster. If I fry chicken.. It's in a electric fry pan outside with paper around it to catch any grease splatter. This is not because I don't like my stove.. It's because I don't like the cooking smell lingering. (Unless it's a sweet potato pie baking in the fall of the year) And during the hot days, I really think twice about lighting this thing up due to the heat it puts out. By the same token..when it's cold, it's the best for heating up the rooms. So yes, gas throws out a lot of heat by comparasion. (At least this old girl does) I do have a carbon monoxide detector nearby, but nothing has set it off. Including the old gas floor furnace. (But there is some soot I clean up in the spring from the furnace in the spring) I had no idea how much I'm polluting the air in the house! |

What a beautiful home you have it reminds me of a TV set its just perfect.
Now I have to ask is there any way you could put like a skirt under that cupboard that's above the stove and install a fan/vent in the cupboard so you cannot see it which would remove any odours and heat from the cooking area I am sure it could be done in such a way that it would be unseen?

When I bought this house in '97, it had zero gas cooking appliances. It has two kitchens, one on the enclosed patio. Both with electric ovens/ranges. The main change I made was to replace the aged, discolored slow Corning glass top cooktop in the main kitchen with a Frigidaire Gallery "Gas on Glass" cook top. Also had the electric GE dryer replaced with a gas unit that I brought with me. Had to have gas lines extended to these locations. The water heater (in a closet in the enclosed patio) and the main house heat (forced air) were already gas. The oven in the main kitchen is a GE P*7 wall oven. It works well enough.
The gas cooktop has a very functional, if loud, range hood over it. But normally I only use the hood if I'm cooking something that might stink up the house. Oh, and I have CO detectors all over the living quarters. Never had one go off. After a few years I got a propane fired Virco stainless grill/rotisserie for the outer covered patio area. This is where I do most of my roasting/grilling. The electric range in the enclosed patio is a vintage drop-in Frigidaire Compact 30. It runs OK although the timer is busted. I don't believe I've ever run the oven on that. I picked up a Modern Maid slide-in gas range that with some mods to the countertop could replace the Compact 30. But I'd have to extend a gas line to that location, which I've put off doing. Since I rarely cook on the Compact 30 I'm in no particular hurry to replace it. I grew up with gas ranges. In older flats/homes the range ovens would be vented through a pipe to outdoors. Newer installations would not be vented, and I was given to believe that improvements in the quality of natural gas as delivered by PG&E made such venting unnecessary. Indoor air quality can be problematic even without any gas cooking appliances. Perhaps what many tightly sealed homes need today are fresh air heat exchangers, which can admit fresh relatively unpolluted air into the living quarters while minimizing loss of heat (or cooling). |

What about the Japanese restaurants that cook on a hibachi on front of you? Those are also gas and turned down right before and after your food gets prepared, there is ventilation above that...
Which is why I like gas for keeping my coffee pot warm, except for the titter-titter the flame makes on my new range, whereas the old one burned silent, so as long as someone is in the house, or I know I will have more coffee, or if not, then turn it off, it’s better than an electric’s lowest that will generate heat that will still cook it or the residual heat after it’s turned off will still dissipate right when I’m ready for that next cup... — Dave |

I LOVE my Frigidaire induction range! The only thing I don't like about induction cooking is when a pot boils over it doesn't make a sound! But the mess is easy to clean up, as the glass doesn't burn the boilover. |

Just be sure you have a good exhaust system that vents outside, and use it even if you are just boiling water in a tea kettle.
This can be a good vented hood, a wall mounted fan or a ceiling mounted exhaust fan, If you have a ceiling fan in the kitchen with gas cooking NEVER run it when the range is on, it causes inverted air currents and poor combustion of surface burners making the pollution problems worse. A ceiling fan also causes air currents that keep vented hoods and wall or ceiling exhaust fans from doing their job.
If your kitchen does not have a vented exhaust system use a portable fan exhausting air from the nearest window to the range, even if the closest window in in the next room.

I did some searching of articles on the proposed health risk from gas stoves.
On one of them from the Rocky Mountain Institute, they have a photo of a gas burner at the top of the page. Guess what? That burner is in extremely poor adjustment, with a massive orange flame. Guess what? That is a badly adjusted burner that is not getting enough air. Of course that will pollute! A well adjusted flame is all blue, with no yellow or orange.

"While it is extremely controversial whether this type of radiation source is actually dangerous, the data is sufficient enough for me to avoid it. The latest information I found that should give anyone pause about bringing an induction stove into their home was published by the Journal Bioelectromagnetics in 2012 (1).
The study authors concluded that most induction hobs (rings) exceeded even the high 1998 maximum exposure levels set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) when a person was standing close to the induction stove. The worst-case scenario was an up to 16-fold increase from these maximum exposure levels! So how in the world did induction stoves ever pass the safety tests? According to Powerwatch, the safety tests assumed that a person’s body is never closer than 1 foot (30 cm) to the front of the induction stove. Standing that far away would be considered “normal usage”. I don’t know about you, but I don’t cook standing at least a foot away from my stove. My arms definitely aren’t long enough! In fact, this would be pretty much impossible if you needed to reach the back burners." CLICK HERE TO GO TO SudsMaster's LINK |

"Exposure of the human body to professional and domestic induction cooktops compared to the basic restrictions."
"ABSTRACT: We investigated whether domestic and professional induction cooktops comply with the basic restrictions defined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Based on magnetic field measurements, a generic numerical model of an induction cooktop was derived in order to model user exposure. The current density induced in the user was simulated for various models and distances. We also determined the exposure of the fetus and of young children. While most measured cooktops comply with the public exposure limits at the distance specified by the International Electrotechnical Commission (standard IEC 62233), the majority exceeds them at closer distances, some of them even the occupational limits. The maximum current density in the tissue of the user significantly exceeds the basic restrictions for the general public, reaching the occupational level. The exposure of the brains of young children reaches the order of magnitude of the limits for the general public. For a generic worst-case cooktop compliant with the measurement standards, the current density exceeds the 1998 ICNIRP basic restrictions by up to 24 dB or a factor of 16. The brain tissue of young children can be overexposed by 6 dB or a factor of 2. The exposure of the tissue of the central nervous system of the fetus can exceed the limits for the general public if the mother is exposed at occupational levels. This demonstrates that the methodology for testing induction cooktops according to IEC 62233 contradicts the basic restrictions. This evaluation will be extended considering." My conclusion: with a gas cooktop, I can turn on the range hood over it and exhaust the pollutants it might emit. With an induction cooktop, there is no way to blow away damaging EMF. I'll stick with gas, or resistance electric, thanks. CLICK HERE TO GO TO SudsMaster's LINK |

From what you guys are saying it sounds like there are people on the planet who cook with gas burners that flame yellow and orange and don't have a problem with it??? Last I heard flames were supposed to be all blue all the time. Or did I grow up in some alternate dimension?" Nobody is saying people who use mal-adjusted gas ranges don't have problems with it. What I'm saying it that an observant homeowner should make sure their gas range is operating to spec, and yellow/orange flames are NOT to spec. Yes, the gas flame should be all blue all the time. If it's not, call the gas company. I remember as far back as the 1960's our local gas company informing customers of this requirement. |

I will add this to the natural gas story: Some years ago, perhaps 20 or more, our local gas company, PGE, notified customers that it was purging its gas distribution lines of a toxic additive, PCB (polychlorinatedbiphenyl) that had been used to help prevent internal corrosion of the pipes.
PCB's are somewhat notorious because they have been used as an insulating medium in electrical power transformers, such as seen mounted high on power poles in neighborhoods. By law it was phased out starting in 1979. It is mentioned as a continuing contaminant in maintained power transformers, which may be how it wound up inadvertently being added to gas distribution lines. In any case I wasn't too alarmed because the announcement stated that residual PCB was in minute amounts, and that the purging of the lines would eliminate the problem. Also I have learned since from Googling the issue, that PCB's can be made less toxic, perhaps non-toxic, by treating them to remove the chlorine atoms and then the cleaned up product can be used as a safer transformer insulation fluid. Anyway, this thread triggered the memory of that announcement and I though I'd share. But I won't point at gas being the evil here, because without electric power distribution transformers the PCB's wouldn't have been used so much. And there is at least one hit in Google that a 16 year old girl was harmed by PCB's leaking from a failed power distribution transformer. |

Oh dear, I must have imagined those asthma attacks.
So they didn't check if the people with gas stoves used them or not? lol! And I haven't seen the difference between allergic and non-allergic asthma being mentioned. As a matter of fact they mention testing for atopy, which means that the people tested positive for that may not have had non-allergic asthma, the type of asthma that gives problems with fumes, smoke etc. |

My catering kitchen had a built in safety device that would not allow any gas to flow without the hood being switched on first it was made to prevent fumes building up and when your stood in front of a 6 ring hob a grill and 2 gas fired fryers you needed something to take the heat out let alone the fumes :)

We're always working to improve and become more efficient and safe.
50 years ago, people were still using coal and wood for heat. Something that is so dirty noxious. When I lived in the Boston area in 2006 one could still find listings in the news paper for people who sold and delivered coal. Unthinkable.
I think that all residential gas service should be discontinued. I think there should be an deliberate effort to convert to electric or solar. In the sunny areas/cities where it typically doesn't get below 40 degrees and we really don't need large quantities of gas they should give it 12 months and have rate freezes on electric as well as offer customers help with installing alternative appliances.
In the north areas they should do similar but offer more help with insulation and heating appliances and funnel the gas to more portable neighborhood gas power plants. But we need to remember that because the U.S. has been getting more efficient in it's electric usage, we peaked in electric consumption around 2012 so there is excess capacity already.
As solar and battery storage continues to take over, the idea of having volatile gas appliances in our homes is going to look as ridiculous as having a coal burner.
And we can't forget, there was actually a time when homes were plumbed for (unvented) gas LIGHTING. Can you imagine the heat build up and poisonous fumes? OMG. .....and the house fires.
Those old technologies served their purpose..... it's just that better stuff came along. CLICK HERE TO GO TO bradfordwhite's LINK

reply # 66 was probably a dramatization of a bad gas flame, no properly working gas range produces a flame that looks like that,
Note : there are no adjustments possible on the great majority of gas ranges built today.
reply #69, I dare say no one has ever been harmed by either an induction cook-top or a microwave oven, up until a few years ago [ last time I actually checked ] there had never been an injury from a MWO caused by MW energy according to HEW which regulates MWOS in the US, this makes MWOs about the safest appliance in a home, I suspect that the injury rate on ICTs will also be a fraction of injuries caused by conventual electric or gas CTs.

I think propane tanks up to 100 lbs are an acceptable risk. If say someone wanted to cook or use a Bar-b-q, or fireplace once in a while.
We obviously have limits on what is acceptable. We don't allow people to buy uranium in easy open packages from the gas stations. We don't allow the easy access to buying mercury in packs of 3 for $10. Nor do we produce Chlorine Triflouride for kids to use in at home chemistry sets (though maybe in the 50s they did).
Leaded gas isn't made anymore.
We change. We improve.
The problem with piped in gas is you potentially have an unlimited supply. With propane, if an empty home sat for say 4 months and had a small leak and it filled the home, it would fill until the tank was empty and then by infiltration that gas would be diluted. If it were a piped service it would fill and fill until inevitably a fire source ignited the gas and it would explode. |

Hi Stan, basically open up the shutters as much as possible till just before the flame starts to blow away from the burner or gets noisy.
Little flecks of orange are just bits of dust etc being burned, if you blow on or around a gas flame you see this happen, if the flame has yellow-orange tips that is too little air or too much gas for the burner.

I’ve adjusted the burner before on my Maytag DG306 I restored last year and and the burner seems to be more noisy and when the shutter is opened up more and seems to be quieter when partially closed. Adjusted it back to the way is was before when I got it and referenced a photo I took of the burner shutter when I first got it

Over a year ago my gas fired water heater stopped working. Had to take a shower at my neighbor's the next day. At my first opportunity I checked out the heater, which is safely out of the house in an enclosed but well ventilated patio area and vented straight up through the patio roof. Turned out some thing clogged the pilot light - it was out. After cleaning the pilot jet and running some gas through the valve, it's been working just fine again. One thing the line there lacks is a little drop tube just before the flex line to the heater, to catch any debris that might happen along. It's on my 2do list.
So yeah, natural gas can have dust and stuff in it that makes the flame vary from blue. But it should be blue nearly all the time. Anybody besides me remember the California electricity crisis of the early 21st century? And the rolling blackouts? Gas ranges sure came in handy during that time, eh? |

I remember my mom saying the price of electricity all of a sudden skyrocketed in the years 2000, and before that the price of electricity was fairly reasonable before the price skyrocketed in 2000. The current house I live in has solar and our electric bill even in the summertime with the air conditioner running is below $100 and there are times where it is a little over $100 but it’s not all that common anymore since solar has brought our bill way down compared to before we got solar.

"I've got 6 CO detectors and they never go off"
How many nitrogen dioxide detectors do you have? Pritdang toxic, specially in an enclosed environment where it can build up. I'm not adendizing. Gas has its place.

Thomas,
I'm surprised a mere 3.5 shake could rupture a gas line. Was it at that infamous wall heater, or elsewhere? Good thing you got that shutoff wrench, and were home to shut off gas at the meter. I've done the same, that is, zip tied a special wrench by the gas line entering the house here. A lot may depend on how close your structure is to the epicenter. Perhaps it was very close to your apartment? I am currently dickering with my insurance agent about earthquake insurance. I did a seismic retrofit 20 years ago, but of course they have no record of it. I found my copy last Friday, and sent them a copy via fax and email. Haven't heard back yet. And of course the premium is due the 21st. I will have to call them mañana to see what's up. I have this premonition that The Big One is going to hit our part of the state (Northern California) this year or in a few years. I haven't had earthquake insurance for 15 years now, but figure it's time to start it up again. Went with the 25% deductible, though, which means I'm out about $100,000 before the insurance starts to cover stuff. Almost not worth it. But if the seismic retrofit is reasonable enough might go with a lower deductible. I did the retrofit myself; the city here has a program to guide homeowners through that, with lower cost permitting and inspection fees. It got to the point where I almost enjoyed just resting down in the crawl space after some hours of retrofit work, LOL. Not any more! |

"Human-caused sources and exposure For the general public, the most prominent sources of NO 2 are internal combustion engines burning fossil fuels.[8] Outdoors, NO 2 can be a result of traffic from motor vehicles.[17] Indoors, exposure arises from cigarette smoke,[18] and butane and kerosene heaters and stoves.[19]" If one is a cigarette smoker, probably better to focus on quitting that, than on gas stoves. Just sayin... Of course, using a range hood while cooking on a gas stove is a very good idea. I'm also wondering what with better insulated and sealed modern homes, if heat exchanger equipped ventilation might not be a bad idea. I will try to see if there are any such products on the market. What I envision would be a unit like a window air conditioner that simply recovers heat from the inside while it brings in fresh air from the outside. |

Thomas,
My mom moved into a quaint apartment complex in San Francisco in the 80's. It had steam heat that she loved. But after about five years the property owner realized they couldn't raise the rents (rent control) as much as they would have liked. At that point the building steam boiler required repairs. Instead of fixing it, the owner decided to rip it out and install gas fired space heaters. The problem for my mom is that instead of a steam radiator in a central part of her little apartment, the gas heater was affixed to a wall in the unit's entry hall, which is where the heat pretty much stayed. The plus for the property owner must have been no longer having to pay for the fuel to run the steam heat, because the gas heaters ran off the units' gas meters, which the tenants paid for. The inappropriate location of the gas heaters was probably in order to avoid having to put proper exhaust systems in the middle of the units - the entrance hall had a window into the complex open back stairwell, so it was easy just to exhaust the heater through that wall. Whenever I visited her in the winter she'd be bundled up and standing in that dim hallway in front of the damn gas heater. It kind of sucked. |

Got it covered. I use the range hood while smoking. I only breathe the N2O once. This post was last edited 05/19/2020 at 07:14 |

My home is forced air gas, with the furnace down in the crawl space. There are two gas fired space heaters on the property: one a wall heater in the enclosed patio, the other in the 1,000 sq ft separate workshop. I've never turned either on, both are shut off at the gas line. I'm told the wall heater doesn't work, anyway. The enclosed patio is well ventilated so I've never been inclined to fix it so it could be started. The one in the workshop is an old big fan forced gas heater, mounted at what would be 8 ft ceiling height if there was a ceiling (exposed rafters). No idea if it works or not. That shop is also well ventilated, so heating it would be rather costly.
One warning: if you do your own gas or air line work, beware of Harbor Freight fittings. I've had a number of HF brass compressed air fittings fail because they cracked at the threads. The plated steel ones are OK. |

JFYI, the coast of California is not going to "fall into the ocean" as the media garbage like to pretend a while back to pump their ratings.
The coast is moving a few inches a year North and cities like L.A. and Sanfrancisco will eventually be part of Oregon, then Washington, and possibly Canada....
This is possible because of the Hayward fault. |

Sounds like somebody "screwed" up!
Glad you got that fixed. Meanwhile I'm dealing with my insurance company, the California Earthquake Authority, and a contractor to try to get the seismic retrofit that was done on this home recognized in order to get a big (25%) discount of my earthquake insurance. Such fun. This post was last edited 05/19/2020 at 20:37 |

No, the Hayward Fault is not responsible for the movement of the California coast northwards. It's just a rather small part of the overall faulting along that coast. The biggest source of South-North movement is the good old San Andreas Fault. Other faults - bigger than the Hayward, are, in addition to the San Andreas: Calaveras, Greenville, March Creek, Concord, Pleasanton, Rodgers Creek, Maacama, San Jose, to name just a few of the 50 or more new faults found along the coast. But the San Andreas is the longest, stretching about 750 miles or more.

Thomas,
I wouldn't get too concerned about tsunamis from California earthquakes. That's because the most common type of fault here is strike-slip, which is consistent with the California coast moving inches to the north each year with regard to the rest of North America. This type of movement does not displace much ocean water. The type of fault that produces tsunamis is the uplift type, such as off Japan where a huge amount of water is displaced, up or down, and the resultant wave can sweep over the coastline and cause major death and destruction. So that's one thing Californians can generally not worry about, unless there's a cataclysmic uplifting quake hundreds of miles off the coast in the Pacific ocean. Which is far less likely than the San Andreas doing its north south dance. I lived through the Loma Prieta quake in '89. I was fortunate in being miles away to the north-east of there, on relatively solid ground. I could tell it was a big quake, but where I was, the motion was more rolling than jerking. I've been in smaller quakes but closer to the epicenter than those can be quite alarming, with sharp jolts and lots of vigorous shaking. As with social gatherings, it's the jerks that cause the most destruction. LOL. |

California has Tsunami zones. Eureka in particular, which also has quite a few earthquakes just off shore. Used to live about 10 minutes from the beach. Heard them.
Also didn't have gas service where I lived.
No, I don't care to revisit the area.... CLICK HERE TO GO TO bradfordwhite's LINK

Los Angeles has that too. Some parts of the city (Santa Monica, Venice and Redondo Beach, for example) even has tsunami sirens. |

Yes, but tsunamis are quite rare in California, and my point stands: the San Andreas fault is not of the type what will produce a tsunami when it ruptures.
There may be other faults far to the west, north and south that generate uplift or slumping that could create a tsunami, but I do not believe that in my lifetime a California based fault has ever caused a tsunami. "Oh, but what about Crescent City in 1964?" you might ask. Well, guess what? That was the result of a huge earthquake not in California, but in Alaska. My point stands: California faults do not create the kind of conditions that create tsunamis. I concur that tsunamis can be generates by fault ruptures hundreds to thousands of miles away, and those may impact the California coast. Just not from a California quake. Similarly, the 2011 Japan quake generated a tsunami that reached California, resulting in zero deaths and a relatively paltry $40,000 in damage. In 2018 a 7.9 quake, again in Alaska, generated tsunami warnings along the California coast, but it fizzled. So yeah, they can happen here, but not from California-based earthquakes. Also, the California tsunami zones tend to be located in areas where the coastline creates a lens that might concentrate and focus the wave. Like Crescent City or Santa Cruz Harbor.

It's interesting to think that the West coast could feel and see results of a earthquake on the other side of the vast sea.
It underscores the fact that we live on a finite planet. The ocean can act like a dishpan full of water and someone bumps the side. CLICK HERE TO GO TO bradfordwhite's LINK

Yes, there was little to no wave action here from the 2011 Japan quake. I'm on the east side of the bay, about 40 ft above sea level. But any tsunami from off the coast would first have to come through the relatively narrow Golden Gate, which would limit the magnitude considerably. And then I'm about 20 miles south of the gate, which also would limit the intensity here. As it was, nada.
Mostly it seems California could get hit by tsunamis generated far out in the Pacific, like Japan, and by the time they get here, they are relatively dissapated. Or from Alaska, again, dissipated and the effects mainly far to the north of the SF Bay Area. Of more concern should be folks on the East Coast of the USA. That's because the big volcano on the Canary Islands could someday collapse into the ocean. And since it's facing west, the resultant tsunami could wipe out some of our east coast cities, towns, harbors, docks, etc. Just sayin'.... |

"ONE of the world’s foremost volcanologists has warned that if a very active volcano on the Canary Islands is the next to blow, the coasts of Europe, the UK and the USA could be devastated by huge mega-tsunamis.
"Professor Stephen Sparks, based at the University of Bristol, made the revelation about Cumbre Vieja, a very active volcano on the island of La Palma, adjacent to the popular holiday destination of Tenerife. He explained to Express Online: “When you have volcanic islands sticking out of the sea, they’re very unstable. And, in some cases, you can get gigantic landslides when part of the island essentially collapses into the sea.

But it seems to me that our east coast will be severely impacted by a tsunami is as likely as our west coast south of Eureka suffering the same fate.

Discovery channel or Learning channel aired that 20 years ago about LaPalma. Miami would be in trouble. |
