Say you have a 1kWh budget of energy to spend to heat a room and access to a variety of heating methods such as an air pump and an electric resistor (space heater or computer). Which one should you choose to maximize increase in warmth? While the electric resistor will convert the energy it uses to heat with a very high efficiency, the air pump will usually heat the room even more because it doesn’t just locally convert electricity to heat, it moves heat from outside the room to inside the room. Further info in [1] and [2]. EDIT: great explanation/details in sibling comment by ’prutschman’. [1] https://www.homecomfortexpertsinc.com/why-are-heat-pumps-mor...
