Air to Water Heat Pumps

Air to water heat pumps extract warmth from ambient air and transfer it to a heat exchanger which heats the central heating and domestic hot water when connected to a water cylinder.

In the home this process is applied when fluid, normally water with anti-freeze, absorbs or emits heat to the soil, depending on whether the ambient air is colder or warmer than the soil. In winter, the heat pump removes the heat from the fluid, upgrades it to a higher temperature for use in the building, typically in under-floor heating. The heat is often in the form of hot water and is distributed around the dwelling by radiators or a low temperature underfloor heating system.

This heating and cooling system is highly energy efficient generating 3-4 units of heat for every unit of electricity used in the the running of the system. As a result this system is also very cost effective and will more than pay back the initial cost over the course of its lifetime.
