An air source heat pump is a highly efficient heating and cooling system that extracts heat from the outdoor air and transfers it indoors, even in cold conditions. Unlike traditional heaters that generate heat directly from electricity or fuel, it uses a small amount of energy to move heat, making it significantly more energy-efficient—often achieving a Coefficient of Performance (COP) of 3-4 or higher. This technology can provide both space heating and domestic hot water for homes or commercial buildings, while also offering cooling in warmer months by reversing the process. Environmentally friendly, it reduces carbon emissions by relying on renewable air energy rather than fossil fuels, making it a popular choice for its sustainability and cost-saving benefits.
