Greatpool is a professional manufacturer of ON/OFF heat pumps, DC inverter heat pumps, air source heat pumps, swimming pool heat pumps, high-temperature heat pumps, and all kinds of heat pumps.

An air source heat pump (ASHP, or air to water heat pump) is a type of heat pump that can absorb heat from outside a structure and release it inside using the same vapor-compression refrigeration process and much the same equipment as air conditioners but used in the opposite direction. Unlike an air conditioning unit, most ASHPs are reversible and are able to either warm or cool buildings and also provide domestic hot water.

In a typical setting, an ASHP can gain 4 kWh thermal energy from 1 kWh electric energy. They are optimized for flow temperatures between 30 and 40°C (86–104°F) suitable for well insulated buildings. With losses in efficiency, an ASHP can even offer a full central heating solution with a flow temperature up to 80 °C (176 °F).

Air to water heat pumps provide efficient commercial and residential heating, cooling, and hot water supply solutions. Heat in cold weather, cool in hot weather, while providing hot water for domestic , commercial and industrial use. Such as homes, house, offices, gyms, hotels, factories, shools, hospitals, etc. More economical and energy efficient.
