    en.wikipedia.org/wiki/Heat_pump

    A heat pump is a device that consumes energy (usually electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle , cooling the cool space and warming the warm space. [ 1 ]

    en.wikipedia.org/wiki/Heat_pump_and...

    A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2] Thus a heat pump may be thought of as a "heater" if the objective is to warm the heat sink (as when warming the inside of a home on a cold day), or a ...

  5. Coefficient of performance - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_performance

    The COP usually exceeds 1, especially in heat pumps, because instead of just converting work to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to where the heat is required. Most air conditioners have a COP of 3.5 to 5. [3]

    The AHRI Cold Climate Certification is awarded to products that demonstrate superior heating efficiency, especially in cold environments where traditional heat pumps struggle. ConnectM's heat pump excels in maintaining warmth without the energy consumption spikes which are typically associated with extreme cold weather.

  7. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    An air source heat pump can be used to air condition the building during hot weather, and to warm the building using heat extracted from outdoor air in cold weather. Air-source heat pumps are generally uneconomic for outdoor temperatures much below freezing. In colder climates, geothermal heat pumps can be used to extract heat from the ground ...
