Nothing about the existence of heat pumps makes "100 conversion efficiency" a misconception.
- lightedman 7y agoThermodynamics, specifically the second law, certainly makes it so. Some of the electronics utilize the energy and thus work is performed, and not all energy is wasted out as heat, nor is all utilized energy perfectly converted into heat.
- nullwasamistake 7y agoIt is. Heat pumps don't create heat, they move it from one side to the other. You can move 3-7x as much heat as the energy it takes to create it
- zubiaur 7y agoEfficiency = Work out/energy in ;) Resistive heating is indeed 100% efficient. There are better ways to heat up things tough.
- hokkos 7y agoHeat pump is 300% to 700% efficient then.
- dogma1138 7y agoHeat pumps are the most effective way of cooling or heating something as long as you have good insulation and the temperature range is within the effective range in which the pump can operate. This is why you get over 100% efficiency in terms of work vs output. Say you have a 100% efficient heater it means for every watt you put in a watt of heat is released to the environment. A heat pump doesn’t releases anything it moves it from one side to another so for one watt of energy that it takes to operate a heat pump you can move up to 10 watts worth of heat (some pumps can be even more efficient than this) form one side to another.
