Description and Benefits of Air Source Heat Pump

Air source heat pump s are used to provide indoor heating and cooling, even in colder climates, and can be used efficiently to heat water in milder climates.

A big advantage of some pumps is that the same system can be used for heating in winter and cooling in summer. Although the installation cost is generally high, it is less than the cost of an underground source heat pump, because an underground source heat pump requires excavation to install its ground loop.

Another advantage of an underground source heat pump is that it has access to the thermal storage capacity of the ground which allows it to produce more heat with less electricity in cold conditions.

Air source heat pumps can provide low cost space heating. A high-efficiency heat pump can deliver up to four times more heat than an electric resistance heater using the same amount of electricity. The lifetime cost of an air source heat pump will be affected by the price of electricity compared to gas (where available).

Also, an air source heat pump does not emit carbon dioxide, nitrogen oxide or any other type of gas. It uses a small amount of electricity to transfer a large amount of heat: the electricity can be from a renewable source or it can be generated from plants that burn fossil fuel.

Another point is that a “standard” domestic air source heat pump can extract useful heat down to about -15°C (5°F). At colder outside temperatures, the heat pump is less efficient; it can be turned off and the premises heated using only supplemental heat (or emergency heat) if the supplemental heating system is large enough.

Finally, it can be said that the benefits are numerous and always aim at a better quality of life, but more than that a cleaner environment, since it is a model of clean and sustainable energy.
