Want to genertate electricty from sunlight? Solar electricity systems capture the sun’s energy using photovoltaic (PV) cells. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. PV cells don’t need direct sunlight to work – you can still generate some electricity on a cloudy day.
An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can extract heat from the air even when the outside temperature is as low as minus 15° C.
Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.
Unlike gas or oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. This means that during the winter they may need to be left on 24/7 to heat your home efficiently. It also means that radiators should never feel as hot to the touch as they would do when using a gas or oil boiler.
Heat your home with energy absorbed from the air around you. Air source heat pumps absorb heat from the outside air This is usually used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home.
An air curtain forms a barrier to stop the flow of cold air. Although the air curtain can contribute to the heating of a building, its primary function is as a thermal replacement for a solid door.
