No it doesn't. An AC essentially transfers more heat energy out than electricity it consumes. Most heating generates exactly as much heat as energy consumed (electric heaters, burning fuels, etc.). Heat pumps are an exception but they don't work well before freezing temperatures.
- cartoonworld 5y agoYeah the defrost cycle limits the heat pumps heating ability, but AC units have a similar limit wrt how much they are able to lower the temperature of the air. AFIAK they can do about 20 F. At this point you need to do some math and add additional units and run them 24/7 nullifying this benefit. Geothermal heat pumps and good insulation solve both.
- jltsiren 5y agoTypical energy efficiency of heating is comparable to AC. The baseline solution is using waste heat from electricity generation and industrial processes. Geothermal heat pumps have become popular in the past decade or two, and lake/seawater heat pumps are seen as the future of district heating systems in dense cities. The big difference is insulation. On the average, houses that need heating are better insulated than houses that need air conditioning.
