I don't know, it almost sounds like you are collecting freezers.  There might be a few people around here who would understand such behaviour, I don't know..... hmmmm.

So are all these freezers plugged in and working?  If so, is there something inside of them?

The illusion of saving money with a (or numerous) food freezers. The idea is one can buy stuff "in bulk" and "save" money by freezing food until needed. All fine and good ....if one follows through with that pattern.

Usually works best with a large volume of people. If there's only one or two people....unless they have a serious eating disorder... the economics aren't supported.

You can't be "losing track" of food items and food isn't to be going bad from being in there too long.
There shouldn't be large open unused space in there either.

When food goes bad the cost of the food item is still incurred even though it's been thrown out. All it takes is a few items to go bad to wipe out any savings one had, plus you have to add in operation costs and in this case, the expense of a brand new freezer.

Heaven forbid the electric goes out or the compressor fails, or some other service emergency happens and the food thaws and goes bad. The value of all that food counts against you because you spent the money. Even if it's food you've grown or animals you killed and had processed. All those things have value.

I went through this with my mother who had a 15 c.f. almond Kenmore chest freezer from 1989. Everytime I looked in there is was a sea of frost and bits of packaged food items sticking out of the frost unrecognizable. Only in the center were there a handful of useable items ... in this 15 c.f. behemoth. She seemed resigned to having a freezer even though it was just the two of them and they had a 24 c.f. side-by-side.

Since the freezer was a tight fit in the room it was in, she thought it would be there forever, ticking away, adding up on the electric bill and making noise pollution...

Nope, one day when they were out, I got the dolly, removed the lid, took it outside, tipped it on it's side, took the hose to it and washed all the frost and dirt that was on the side out, and put it back together in the garage. She ended up selling it.

And they seriously didn't need it or miss it. It was just a habit and an expensive one at that. It was just an excuse to waste food and money.

I only have a small 3.5 c.f. chest freezer. And that's too big for me. I did an experiment earlier this year and turned off the freezer and redesigned my eating patterns for a life with no freezer.

What I found is I ate healthier and it helped me to lose weight. Plus I saved on not buying frozen food and on electric costs.
I'll probably replace what I have with a small 1.1 c.f. freezer soon.

I've had my Kenmore ~14.5 cu ft chest freezer for probably about 20 years now. Still works fine. However I probably need to clean it out because I've sort of lost track of what I put in there a couple years ago.

It's my understanding that chest freezers are more energy efficient than upright freezers. Probably because all the cold air doesn't exit every time you open the lid, as it can with an upright freezer door.

One problem I've noticed with the chest freezer is that it's easy to overfill it and not notice right away. But due to the lid not closing all the way from the overfilling, moisture from the room air can enter and cause frost on the inner front of the chest cavity. And that's what I just observed when measuring the inner chest. Probably time for a scraping, and, later, moving all the contents out for a full defrost. This one has a little "flash defrost" pin one can pull, which can run current through some coils in the walls to melt any accumulated ice, which can speed up the defrost process. There is also a drain at the front of the cabinet.

I doubt that the "hot gas" method of defrosting would save much energy vs. the electric coil method, because a chest freezer only needs defrosting every couple of years or so. In my experience, the electric coils melt the frost in perhaps 30 minutes to an hour.  And it is probably more expensive to mfg a gas driven system than an electric system, as well as the gas system being more liable to break down.

Mainly I see frost in my chest freezer when I've over-filled it and the lid hasn't closed completely. That's what's recently happened, so time to get out the scraper and get rid of some of the frost.
