Square Air Source Heat Pump, 200 L

An air source heat pump (ASHP) is a renewable heating technology that moves heat from the outside air into a building to provide space heating and hot water: How it worksASHPs extract heat from the outside air and increase its temperature. They can then transfer that heat to a building's wet central heating system or to radiators or underfloor heating. TypesThere are two main types of ASHPs: air-to-water and air-to-air. Air-to-water ASHPs feed heat into a wet central heating system, while air-to-air ASHPs can provide heating and cooling. EfficiencyASHPs can be more efficient than traditional heating systems: They can deliver up to two to four times more heat energy than the electrical energy they consume. They can generate 3.5kWh in heat for every 1kWh of electricity used. They don't use polluting gas or oil.
