I'm curious how the real world numbers work out here. Assuming that you're using electric heat to heat the house, I get that a traditional fridge is better than venting heat outside.
But, if you have a ground source heat pump as your home's heat (sourcing from 45° ground temps) - wouldn't it be more efficient to use the outside air as a source for a fridge?
- Scoundreller 7y agoThe ground source heat pump works exactly the same as the fridge does. And the fridge is extracting heat from an approx. 40F heat source. So not much of a difference. The ground source heat pump will be pretty efficient if it's hitting deep and wet soil to get a good heat exchange. But if we're comparing to resistive heating, an air-source heat pump near/below freezing points, propane or even natural gas, the economics move in favour of the electric fridge.
