2. Air source heat pump - Wikipedia

   en.wikipedia.org/wiki/Air_source_heat_pump

   In the UK, annual heat pump sales have steadily grown in recent years with 26,725 heat pumps sold in 2018, a figure which has increased to 60,244 heat pumps sales in 2023. [80] ASHPs can be helped to compete by increasing the price of fossil gas compared to that of electricity and using suitable flexible electricity pricing . [ 19 ]

3. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   Specifically, the heat pump transfers thermal energy using a heat pump and refrigeration cycle, cooling the cool space and warming the warm space. [1] In winter a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in summer.

4. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.

5. Micro combined heat and power - Wikipedia

   en.wikipedia.org/wiki/Micro_combined_heat_and_power

   The future of combined heat and power, particularly for homes and small businesses, will continue to be affected by the price of fuel, including natural gas. As fuel prices continue to climb, this will make the economics more favorable for energy conservation measures, and more efficient energy use, including CHP and micro-CHP.

6. Air conditioning - Wikipedia

   en.wikipedia.org/wiki/Air_conditioning

   The heat pump is significantly more energy-efficient than electric resistance heating, because it moves energy from air or groundwater to the heated space and the heat from purchased electrical energy. When the heat pump is in heating mode, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat.

7. Renewable heat - Wikipedia

   en.wikipedia.org/wiki/Renewable_heat

   The efficiency of a heat pump is measured by the coefficient of performance (CoP): For every unit of electricity used to pump the heat, an air source heat pump generates 2.5 to 3 units of heat (i.e. it has a CoP of 2.5 to 3), whereas a GSHP generates 3 to 3.5 units of heat.
