2. 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.

   Here's what's driving up home heating costs, and how much families are expected to spend this winter.

4. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The heat pump itself can be improved by increasing the size of the internal heat exchangers, which in turn increases the efficiency (and the cost) relative to the power of the compressor, and also by reducing the system's internal temperature gap over the compressor. Obviously, this latter measure makes some heat pumps unsuitable to produce ...

5. Air source heat pump - Wikipedia

   en.wikipedia.org/wiki/Air_source_heat_pump

   Although higher cost heat pumps can be more efficient a 2024 study concluded that for the UK "from an energy system perspective, it is overall cost-optimal to design heat pumps with nominal COP in the range of 2.8–3.2, which typically has a specific cost lower than 650 £/kWth, and simultaneously to invest in increased capacities of renewable ...

6. 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 ...

7. Zero carbon housing - Wikipedia

   en.wikipedia.org/wiki/Zero_carbon_housing

   As heat pumps often use lower flow temperatures than traditional fossil fuelled systems, homes may need improvements in insulation and larger emitters (eg radiators) when they install a heat pump. One study estimates the embodied carbon in a UK installed heat pump at 1563 kg. [ 8 ]
