Yes.

Heat pumps are more efficient at heating than resistive elements because they take advantage of already existing environmental heat, whereas resistive heating has to generate all of the heat directly.
- wjnc 7y agoThanks for this insight. Never thought about this. I'm still on old-fashioned gas so in my case the only difference is one of gas being cheaper per joule even after the (in-)efficiency of burning than electricity. But indeed in the heat pump world you get more joules in heating than you put in in Wh of electricity. Still you should amortize the cost of pump per joule of heating. Bulbs were _cheap_.
- WAHa_06x36 7y agoNo, what you should be amortising is the cost of the collapse of ecosystems and drowned cities due to global warming. Stop burning gas.
