Heat Pump

A heat pump is an energy-efficient heating and cooling system that transfers heat between indoor and outdoor environments rather than generating it through fuel combustion. In winter, it extracts heat from the air, ground or water and moves it into a building. In summer, the process can be reversed to provide cooling. Common types include air-source, ground-source and water-source heat pumps. Because they move heat instead of creating it directly, heat pumps can deliver several units of thermal energy for each unit of electricity consumed. Their efficiency, cost and emissions performance depend on climate, building insulation, system design, electricity prices, refrigerant choice and installation quality. When powered by low-carbon electricity, heat pumps can significantly reduce building emissions and dependence on fossil fuels.
