    In cold weather, a heat pump can move heat from the cool outdoors to warm a house (e.g. winter); the pump may also be designed to move heat from the house to the warmer outdoors in warm weather (e.g. summer). As they transfer heat rather than generating heat, they are more energy-efficient than other ways of heating or cooling a home. [2]

  3. Are heat pumps the key to accelerating the energy transition?

    Heat pumps consume a lot less energy and are at least three times more energy efficient compared to conventional heating and air conditioning systems. Heat pumps cost a bit more upfront but do ...

    The Government has written that a heat pump “generates 3 times more energy than it consumes”. Evaluation. Heat pumps are highly efficient and can release three times as much heat energy into a ...

  5. Thermal efficiency - Wikipedia

    en.wikipedia.org/wiki/Thermal_efficiency

    The reason the term "coefficient of performance" is used instead of "efficiency" is that, since these devices are moving heat, not creating it, the amount of heat they move can be greater than the input work, so the COP can be greater than 1 (100%). Therefore, heat pumps can be a more efficient way of heating than simply converting the input ...

    Moreover, electric heat pumps are more efficient than electric resistance heating systems like baseboard heating, so they even reduce emissions relative to other electric heating systems.

  7. Seasonal energy efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Seasonal_energy_efficiency...

    A refrigeration cycle can be operated as a heat pump to move heat from outdoors into a warmer house. A heat pump with a higher SEER rating for cooling mode would also usually be more efficient in heating mode, rated using HSPF. When operated in heating mode, a heat pump is typically more efficient than an electrical resistance heater.
