Heat Pumps are and not your best depending where you are. In the colder weather we get here you use alot more electric resistance heating but you have a whole house A/C in the real warm weather. Friends of mine put an expensive geo-thermal system in when they built their house and they are very comfortable and much happier with the lower energy bills.

As the temp drops electric resistance heat is phased in bit by bit as needed.Depends on the design and capability of the system. Newer and/or higher-end systems have two or more sets of individually-staged heat strips. Lower-end units such as mine may have more than one set of elements but run them all or none. I can turn off one of the breakers and have only one set able to run but the system can't do that automatically. | ||

Have a reasonably low priced 
HVAC its only works in one room but will drop the temp in the whole house when its hot and I have used it a couple of times to warm me instead of the electric fire it will heat the room very quickly with the doors closed but we have a very good hot water/radiator system that heats the whole house, If I had realised how good these new systems are I would not have updated the central heating but would have had 3 heat pumps put in as that would have been less than the new boiler.... Live and learn.

There is no natural gas on my street. Houses are all electric and range in age being built from 1972 to 1984. Mine was one of the last two built. The HVAC was a RUUD heat pump, albeit builder's grade. It was one of the reasons why I bought my home. I was familiar with heat pumps. Friends that used to live behind us in our old house were responsible for us moving to the new house September 1961. Their house was a gold medallian all-electric house and had a heat pump. The most recent artic blast was the 2nd coldest I've experienced since living in this house since January 1986. The lowest it got was 2 degrees F. The coldest was a couple of days before Christmas 1989 and it got down to -4 degrees F. The RUUD heat pump couldn't keep up and could only heat the house to 64 degrees with the emergency heat setting. My current Trane XL20i kept the house at 69 degrees despite all the snow & I that was around it. I couldn't get near it because of all the snow & ice to clear that from around the unit. I got my bill last Friday, 1806 kwh for the billing period. In the past two years, my highest consumption was 1550 kwh in June 2019 or July 2020. So I was pleased.

When I replaced out mini split last September I went with a heat pump model as it was only a negligible cost increase. I figured if for some reason our boiler went down I'd have some sort of heat until it was fixed. I was a bit too nervous to even turn it on these past few weeks of minus weather thinking that with my bad luck of late with appliances it would probably break in that cold and I'd have another big kerfuffle to deal with. I did turn it on last for a few minutes because it was just above freezing, and it did pump out a lot of heat.

Heat pumps NOT a good product.
Mini-Split AC ONLY units are a very good product however. Baseboard heaters and EXCELLENT insulation is the best way to heat. We've lived and experimented long enough now to know that insulation is key to keeping our environments comfy whether heating or cooling. Baseboards make no noise, have no moving parts, are cheap to install, have 100% efficiency, can be controlled per each room, They don't explode or kill occupants silently, there are no dirty ducts to worry about, oh and again Q-U-I-E-T. And quiet is the reason to choose a mini-split. Preferably a 120 volt model that way if you have a solar system you can use a standard 120 volt inverter to power it. I used mini split heat pump last year. I knew as a heat source it wouldn't work because heat needs to be coming from floor level. A mini split is hung up high on a wall which means you'd have to blow the heat down. So there's the draft. Then there is the unnecessary noise. I HATE mechanical noise. Our world is polluted enough already with idiots making noise. I also owned a home in the Chicago area that had been made "all electric" in the 70s with a heat pump. Terrible. That fan had run so long on the air handler it was vibrating terribly. When it came on there was the cold draft. Then MORE noise from TWO units running. That thing got ripped out and put in a standard gas furnace and AC unit. This was 2003. I will never install anything with duct work again either. All that dust you don't have access to plus it's difficult to zone rooms. Then there is the cutting of the structure to install them. The noise that vibrates from room to room. No. ---- Mini splits can be bought and self installed with the pre-charged lines. There are vids on YouTube showing how to do it. This one is 12,000 BTU. Depending on your insulation that can do quite a bit of space.

Ours Kicked ass up at the farm when it got down to the single digits .
I grossly oversized it the Mitsubishi Hyper heat,but when you have a inverter compressor that is less of a problem.. I turned off the 2 American standard split heat pumps and just left the fans on and set the temp at 73 on the Mitsubishi just to see if it would have any issues. Its a 48k unit with 4 indoor units . I have two down stairs and one in the middle and one on the very top floor. The unit did not even struggle the air coming out is HOT HOT . My Dad is going to rip out the Trane And American Stand heat pump units and go with Mr Cool brand. Those units are 14 years old, We have had a great service from MR cool and sense the Trane Handlers are new as is the coil that Mini Split will work. They heat down to -22F . Trane used to be the best not anymore. I have seen 4 new Trane Heat Pumps in a new tract of Homes and the Tranes are all using L.G. compressors. They could of went with Copeland compressors. I would have went with Panasonic or Toshiba Scrolls before I touched L.G. | ||

In my location, I still believe natural gas is still the cheapest and most effective way to heat a home. Sure, in areas without natural gas service, heat pumps/split/whatever make sense.
And they also could make economic sense if one's home is equipped with solar power panels. The point about insulation is spot on. When I bought this house in 1997, it had poor insulation. I noticed that first winter that the forced air central heating system would run for hours continuously on cold evenings. That spring I went out and corrected a number of deficiencies: 1) Insulated between the ceiling rafters in the attic (1 story home) with about R-25 or more. Previously there was zero insulation up there. 2) Sealed off many air leaks between living areas and the attic. I was kind of surprised at how many there were. 3) Renewed the felt strips on the sliding aluminum windows. They used to rattle on windy days, no doubt letting warm air out and cold air in. Now they are quiet. Yes, I know, double pane insulated windows are even better, but I don't think the cost is justified. This is because outside of air leaks, windows comprise a small fraction of the living space envelope. 4) Insulated the heating and return air ductwork under the house. Once I had done 1-4, the next winter (and to this day), even on cold nights the furnace comes on for maybe five or ten minutes per hour max on cold nights. And the heating bill for gas service was slashed at least in half. Also in order to prevent moisture build-up in the attic (there was some sign of black mold on some of the roof rafters), I installed soffit vents all around the structure. This probably didn't affect energy consumption but no doubt helped the structure resist moisture issues. 5) The next year I went in and insulated under most of the first floor, over the crawl space. My preferred insulation material was Miraflex - a type of fiberglass that resembles polyester fiber fill and doesn't shed nearly as much of the itchy glass fibers that regular fiberglass does, nor does it contain the formaldehyde that regular fiberglass bats may have. Unfortunately Owens-Corning has since discontinued the product :-( ... But I got enough of it to address all of the attic and most of the flooring. (Note: some web sites state that Owens-Corning didn't discontinue Miraflex, but that Home Depot only stopped carrying it. This doesn't seem to be true. I just visited the Owens-Corning website and searched for Miraflex and came up with no results. I have no idea why it is no longer being made.) | ||

Consumer Reports chimes in....
www.consumeraffairs.com/h... For those of us who've never heard of much less seen a hybrid water heater this Old House to the rescue. In our area electricty cost far more than oil or gas, thus few will use it for water heating or any other major means of generating same if they can help it. That is unless it can be made to work out to be cheaper. | ||

"Avoiding any of the nonsense which always pops up when you discuss energy saving appliances..."
I guess by "nonsense" it implies those pesky mean laws that ban toxic chemicals that are ruining the ozone layer? We don't really need an ozone layer, do we? Future generations don't even want Ozone. No. Baseboard and flat-panel electric heaters don't have toxic volatile gasses that will eventually escape and/or need replacement. One does not have to have a license to install or plug in a baseboard electric heater unlike a refrigeration guy that has all those expensive tools, gauges, and bottles of explosive gas to carry around. | ||

bradfordwhite, your post is a perfect example of what I was referring to. I come here to look at what makes things work, and how to keep them going; as do quite a few others. Your post contributes nothing and serves only to incite negativity. I refer to this sort of chaff as "nonsense." I hope this answers your question.

Heat pumps have always made sense since their inception
In 1955 my aunt Margaret’s parents built an all new all electric home in Illinois.
The Home featured a ground source heat pump system. The house was very well insulated on a small farm it had an electric range and electric KitchenAid dishwasher and a Bendix washer dryer combination and all the other modern conveniences of the day, and the annual electric bill was between 95 and 105 dollars yes that was the cost for an entire year of electricity. Until the 1970s when prices of electricity started to go up. I remember the first year when he complained that it cost over $200 around the late 70s to operate this household for an entire year LOL Heat pumps have always made sense because you’re just moving heat around not creating it. Heat pumps will be the predominant heating and cooling system the world over if it isn’t already very soon. John | ||

Heat pump
Yes, a Heat Pump, does not involve "creating" heat, as John and others have said but simply re-locating pre-existing heat from one area to another.
Heat is the flow of thermal energy from one body to another. Thermodynamics state that heat must flow from a warmer object to a cooler object. In the Winter, heat wants to flow OUT of your house to the colder outside air. A heat pump supplies just enough energy to move natural, pre-existing heat, contained in the outside air into your home. When it is, say zero degrees F, it doesn't seem as if there is much heat out there. BUT... Absolute zero, which is almost -460 F, is the coldest temperature that can exist in our Universe. So when it is 0 degrees F outside, we still have 460 degrees of heat available in the air. More than enough to boil water! Your heat pump just uses enough energy to move some of this heat from the outdoors into your home. From reading the postings here, and talking to others, it seems that people either hate or love Heat Pumps. Those who have never had one develop their opinions based on which of the two groups of people they have talked to, not from personal experience. I have found that those who hate Heat Pumps, and have actually had one, are victims of improper installation, a low quality/less efficient unit, or improper operation due to ignorance. ("Ignorance" not meaning to be an insult, but meaning "not educated" or "not knowledgeable" of proper operation.) Like the garbage disposal, the heat pump is laden with Old Wive's Tales of misinformation. Many HVAC dealers do not take the time or money to properly install a central Heat Pump. Heat pumps are a different animal and operate by moving large quantities of air for longer times--since the temperature differential between air going into a heat pump and coming out is less than say from a fossil fuel furnace, such as a gas or oil-fired furnace. Larger ducts must be used, and larger registers. Conventual heating systems often use the typical 4 by 10 floor registers, heat pumps must have a minimum of 4 by 12 inch registers or larger for most room sizes. Builders are probably the number one source of Heat Pump irritation. They often use the lowest quality/efficiency unit they can find. They often do not properly size ducts, nor registers and rarely strategically place registers and cold air return intake vents. The result--an unhappy homeowner. don't blame the heat pump, blame the lazy and greedy builder. I have read comments about a heat pump running "all the time." Actually, that is normal and that is the way they are designed. Near the balance point a heat pump should be running continuously or near continuously....moving large amounts of air with low temperature differentials. The air is not supposed to necessarily be hot such as from a gas furnace. However, in mild weather, yes, heat pump air can be hot enough to nearly burn your hand on a register if you leave it on there. As outside temperature goes down, so does the the temperature of the air exiting from your Heat Pump air handler. To compensate, the heat pump runs longer. When in perfect balance, heat loss from your home equals heat gain from your Heat Pump, your heat pump will be running continuously. It is supposed to. When continuous running cannot balance the temperature, then the auxiliary heating will come on sporadically to add heat energy to the air. (This auxiliary hear is often electric, but doesn't have to be. It could be gas, etc.) For simplicity, I am talking about an "air source" heat pump. Not geothermal. Air-source meaning it is pulling heat out of the Winter air. A house with leaking windows, or under-insulated can change the balance point to occurring at a higher outdoor temperature. A super-insulated house or very well constructed house can lower the balance point tremendously. The more efficient the heat pump, the lower the outdoor air temperature is at which the balance point is reached. Heat pumps are now most often listed with SEER (Seasonal Energy Efficiency Rating). Such as 11, 14, etc. Less often seen is the COP, Coefficient of Performance. This is the ratio of energy put into to the system compared to the heat energy put out by your Heat Pump. For example, a COP of 3.0 for your heat pump, means that at a given outdoor temperature, for every unit of energy you put into your heat pump, you get three units of heat energy out. I don't recall the COP, exactly, of straight electric resistance heat but it is quite high around 99.7 or something in that vicinity. So, for every unit of energy you put in, you get almost one unit of heat energy out. Little is lost due to efficiency. With a heat pump, manufacture's rate at two typical outdoor temperatures, one of them is 17 degrees F. So a COP for a residential heat pump might be, for example, 2.3 at 17 degrees F. Meaning at this outdoor temperature, for every unit of energy you put in you will get 2.3 units of heat energy out. Many residential heat pumps retain COP's greater than one into the single digits or even below zero. That is why Heat Pumps are ecologically such sound ways to heat your home. Often, I find people do not understand that most heat pump thermostats are programed to kick in the auxiliary heat if you turn them up 2 degrees or more at a given time. If you have an "Aux Heat" indicator light you will see it come on. The thermostat thinks you are cold and want heat fast, so the aux heat will speed up your getting the house warm. Of course, you just dumped money down the drain when you utilize you auxiliary heat because you may be creating heat with a COP of nearly one, when you could have been using the heat pump to move heat with a COP of, let's say 3 or 3.5 or more. Unless you are shivering in your boots, it is best to never turn a heat pump up more than one degree at a time. If you are still wanting a higher room temperature, wait until the room comes up to temp, then turn up the thermostat another degree. If you turn your thermostat down at night, most modern programmable heat pump thermostats will compute at what time in the morning to start heating the house, using the auxiliary heat as little as possible, to get it up to temperature at your waking time. Oddly, many of the newer thermostats do not have the Axillary Heat indicator light. Some have none, and some show a small icon or word that one may easily overlooked. Thinking back, and adding up, I have had five homes/apartments with Heat Pumps. My current home is my fifth house equipped with an air source heat pump. I love them. If you understand them, know what to expect, and how to use them, they can save you a lot of money. You are not burning any fossil fuel (it's much more efficient, and cleaner for your electrical utility to burn fossils fuels, centrally, that it is for each separate house to do so). There is no danger of gas leakage, carbon monoxide, or explosions. A Heat Pump, as mentioned, is a different kind of animal. You can't expect a cougar to act like a wolf. They are different creatures but each has its own beauties. A Heat Pump is not a gas fired furnace, nor is it a coal unit, nor an oil fired unit. So quit thinking it should act like one. A heat pump will run near continuously or continuously in very cold weather, it is not going to give toasty feeling air out of the register at very cold temps, and you have to have the knowledge to know how to operate the thermostat so as to not kick in the auxiliary heat. The continuous air is a good thing, it means continuously filtered and circulated air. The lower register air temps (in very cold weather) means the moving air is not as drying to the skin and you get greater temperature uniformity around the house as you do not have zones of blasting hot heat near the registers. Heat pumps aren't for everyone, but if you want greater efficiency using natures heat, you like greater temperature uniformity in your house and cleaner air then you probably will become best friends with your Heat Pump should you decide to get one. :) This post was last edited 03/13/2021 at 11:46 | ||

Barry, thank you for taking the time to provide such an excellent, detailed explanation.
As I've stated a few times previously, I knew my builders grade HP was not good compared to one my parents had in their vacation home. And thanks to John L (Combo52) for providing me with information at the 2002 wash-in that when times comes for me to replace my heat pump, to get one with a variable speed air handler and multi-speed compressor. Which I did and experience was like night & day difference. | ||

No one's preventing you from learning. Everyone, including myself, have presented quality ideas.
Life is full of ideas and concepts. Some work better than others. Some are better fitted to certain situations. It sounds more like you're only looking for a monotone choir to preach the joys of something. Starting a thread requesting that "only those who want to speak positively about xxxxxx...." would be suggested. Or would that be too blatantly exclusionary? It's not presenting reality but people do it. | ||

heat pump water heaters, especially if installed inside a house are a terrible idea.
They make loud noise vs. total or near quiet of electric and the soft burning sound of a standing pilot water heater when it's heating. What's worse is (unless they've changed how these are made), they aren't vented to the outdoors which means the cold air they are creating when running is being dumped inside your home. That might be fine for summer but if it's winter you don't want something adding yet MORE cool air when you are trying to heat the air. These are ridiculously expensive and because they have all these moving parts it's going to require expensive repairs and certainly won't last long. My Aunt and Uncle built a new house in 72 with a standard 40 gallon electric water heater. They sold the house in 99. She admitted they were lucky because it lasted all that time without them doing anything to it. The only maintenance an electric water heater needs is to occasionally drain water off the bottom. She stated they never did that. lol. And it lasted all those years. ---- Remember- Not encumbering one's self with complicated possessions and obligations is one of the most complicated but rewarding things a smart person can do. You can always tell the true intelligence of a person by the lack of liabilities they have around their neck.

I've been following this thread with interest, but I must say I was pretty flabbergasted that there would be such a thing like a heat pump water heater with an indoor heat pump. Never heard of that!
Overhere in the NL we have combined systems, water heater and heating system in one. Now try that with an indoor heat pump! lol | ||

Heat Pump Water Heaters Are Wonderful Energy Savers and for homes in the US without Natural Gas are one of the biggest money and energy savers available at a reasonable cost to the home owner.
US HPWHs are all installed indoors, the compressor in integrated on top of a 50 gallon water heater.
Having lived with one and the many friends I have with them every body I have talked to about them loved them.
The many advantages of having the entire unit indoors is the unit assists in cooling and dehumidifying in warmer months which is over 1/2 the year in most of the US.
Noise levels are very low, usually less than a dehumidifier.
The power consumption is around 1,200 watts compared to 4,500 for a typical US electric heater. They need to be in an area with ventilation [ not a tiny tight closet ] If the ambient temperature goes much below 50F it may revert to resistance heating.
From talking to people with HPWHs you usually save $20 a month for a single person living in a house, most people in the US are entitled to a Federal tax credit of $500, state and unity credits in addition often bring the cost down below $500 installed or about the same as a cheap electric water heater.
All major water heater makers are selling lots of these in the US, the department banned sales of residential WHs over 50 gallons except for HPWHS several years ago.

I was really drooling over the potential of replacing my Whirlpool Energy Smart HWH with a Hybrid Water Heater but my water heater is located in raised closet in the garage next to the air handler for my HVAC, so no go. At least Rheem/Ruud offers a water heater with similar concept as my current water heater--"intelligently" maintaining reserve temperature based upon usage patterns and will maintain at a lower temperature but then increase to set point when demand requires it. The Rheem also has an app whereby you can control the temperature from your phone, which would be helpful if I ended up with having a SQ front loader and could increase temperature from what I currently keep at (120-125) and increase the temp to 140 or 145 when I have to do a "sanitize" wash since it doesn't have an onboard heater.

Want to boost water temps for your washer.
Try a compact 2 1/2, 4, or 6 gallon 120 volt water heater with a 30 minute switch. Before you're going to do laundry simply turn on the switch and let it heat the water to 150 degrees. Connect the washing machine hose directly to the water heater and connect the water heater inlet hose to the hot water faucet. It only uses electric for that short period of time. Very efficient and no noise pollution. Affordable and easy to install. | ||

It looks like (once again) EU countries and those affiliated, are doing things in a logical way compared to us in the U.S. No surprise.
If one is going to use a heat pump, you'd want the heat exchanger outdoors. I'm happy to hear that they at least exist. It's totally inferior to want that noisy contraption indoors dumping cold air. I remember looking at a model home with one of these things in it and it was running and I was like what is that noise in the basement? ehhhh. This is like those vending machines that weirdly make a LOT of noise when all they are is a refrigerator that never gets opened. It should make less noise than a household refrigerator, not more. Noise pollution is such a problem in the U.S. We should do everything to avoid adding to the problem.

Likewise there are people in cold climates or during periods of cold, icy weather but the electric is working, that have vented their electric dryer indoors. Not a gas dryer because of course the asphyxiation risk and the smell and soot. This way one can capture the heat and humidity. I've done that myself. But it creates a lot of dust.

Yep, but not ALL the products which means it's not a free and open market here in the U.S.
WHERE are the heat pump water heaters that one would install outside? Where is an affordable compact car like the Hyundai i10? And why don't most "Americans" have access to public transport? A closed or BIASED market especially in an increasingly world market is not acceptable. If one diverts the dryer vent to vent inside, that's very simple. If one were foolish or innocent enough to have a loud heat pump water heater INSIDE their home and it's cool outside so you have the heat on, how are you going to divert that cool air outdoors? | ||

Installation in a 31" x 28" broom closet in a small indoor laundry room obviously isn't ideal. A larger laundry room may be workable. A garage or exterior storage area would be perfect. Sister's water heater is in the attic. Not a good location for a 40- or 50-gal tank of water ... but being that's where is it, workable for a hybrid. A.O. Smith units cite an optional duct kit for installation in a "confined" space. Some Rheem units I checked cite refrigeration of 4,200 BTU (a small window unit) and noise level of 49 dBA. | ||

Being from a northern state, the idea of a water heater in an attic seems ridiculous.
However, for a southern state it's actually a really good idea because 1. heat rises. Attics get hot helping to heat water and keep it hot, thus saving money and energy. Also, the heat from the water heater doesn't enter one's living environment. Another positive. 2. Southern homes don't usually have basements so it saves space by putting it in unused attic. 3. If it's gas it's got a short chimney and the gas is outside your living space. The only thing is having a attic flor that can handle the weight and leaks. Having a pan under would def. be a requirement. | ||
