Air source heat pumps, as the name suggests, is a device which effectively takes latent warm air from outside, and uses it to heat your water system, both for hot water and central heating.
Whether your home or premises has its water heated by gas or diesel, the savings and benefits of a heat pump system are nothing short of spectacular.
The heat pump itself looks very similar to an external air conditioning condenser unit and for the most domestic buildings, is about the same size.
Because of the inverter technology used in these systems they are also very cheap to run. Typically, for every Kw of power the unit consumes, it outputs 3-4 Kw of heated water, making these modern heat pumps very efficient and slashing huge amounts off your heating bills.
