  • My refrigerator has 200w of draw and most of that goes into doing the refrigeration, so a few dozen watts of waste heat is my estimate based on my refrigerator. Which isn’t a big refrigerator, it’s definitely on the small size. A bigger refrigerator with a more powerful compressor will produce more waste heat but it’ll still be small compared to the energy put in to do the work. And it’ll be tiny compared to the wattage of a heater which top out at 1500 watts.


  • It also won’t put out much more heat than is already in the room. It evacuates heat from it’s interior, heat that was already present in the room. If the room was colder than the inside of the fridge, it wouldn’t produce any heat at all. the thermostat would cut off after the temperature equalized and it wouldn’t run at all.

    When it does run it produces maybe a few dozen watts of waste heat. Definitely not useful to heat a space with.


  • GE currently sells a heat pump water heater on the market, I’m not sure if it uses resistive heating to supplement the heat pump

    I have a portable A/C with a heat pump and it starts to struggle to heat my apartment once it gets down to 45-50F outside and it struggles to cool once it gets above 95F.

    Your AC may be undersized if it doesn’t perform well in hot weather, also unfortunately many heat pumps aren’t optimized for extreme cold weather performance. Some are, it’s definitely not a failure of heat pumps in general, but you’ll only find those as permanent install units and they’re usually only sold up north.










  • Working smarter not harder doesn’t mean pulling harder to get it out. It means chipping away at the problem, literally.

    If you cut the stone around the sword, either to enlarge the crack or remove the piece of stone with the sword in it, you can get it out with slightly more effort cutting the stone, but none of the brute force effort required to pull it out. Which also eliminates the risk of breaking the sword.

    These days it’s so easy to cut stone with power tools, it’s not like in the old days where that would be a slow process that would take months if not years. A stone cutting chainsaw can do it in minutes.
