4. Zero carbon housing - Wikipedia

   en.wikipedia.org/wiki/Zero_carbon_housing

   Heat pumps — powered by electricity, deliver high efficiency by drawing on the heat energy in ambient air/ground, heat pumps can deliver an apparent effiency of 400% or more, i.e. heat delivered is 4x the electrical energy in. May use air, water or ground as the heat source, and can deliver heat as warm air (air to air heat pump) or via a wet ...

   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. Renewable heat - Wikipedia

   en.wikipedia.org/wiki/Renewable_heat

   Though capital intensive, heat pumps are economical to run and can be powered by renewable electricity. Two common types of heat pump are air source heat pumps (ASHP) and ground-source heat pumps (GSHP), depending on whether heat is transferred from the air or from the ground. Air source heat pumps are not effective when the outside air ...

7. 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.
