Curious if this would have any noticeable energy savings. Basically thinking of taking old semi-disposable plastic containers (the ones that like deli meat, butter, etc come in), freezing them outdoors, and letting them defrost (absorb heat) in the fridge/freezer. Basically back to the “ice box” model.
Anybody doing that and/or have any results to share? Mostly curious if it would be worth the effort.
Lol, yeah. Though the exhaust heat from the refrigerator does warm the house (good in winter, not good in the summer).
Definitely have had the thought about a thermostat controlled vent that would utilize outdoor air when the temperature permits. Might be one of those ideas that’s nice but impractical.
I think the next level of after heat pumps is complete heat management. Waste heat from kitchen exhaust? Heat pump. Hot water down the drain? Heat pump.
