2. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   In general, heat pumps work most efficiently (that is, the heat output produced for a given energy input) when the difference between the heat source and the heat sink is small. When using a heat pump for space or water heating, therefore, the heat pump will be most efficient in mild conditions, and decline in efficiency on very cold days.

   According to the US EPA, geothermal heat pumps can reduce energy consumption up to 44% compared with air source heat pumps and up to 72% compared with electric resistance heating. [4] The high purchase price of a heat pump vs resistance heaters may be offset when air conditioning is also needed.

5. Thermal efficiency - Wikipedia

   en.wikipedia.org/wiki/Thermal_efficiency

   Therefore, heat pumps can be a more efficient way of heating than simply converting the input work into heat, as in an electric heater or furnace. Since they are heat engines, these devices are also limited by Carnot's theorem. The limiting value of the Carnot 'efficiency' for these processes, with the equality theoretically achievable only ...
