Air Sourced Heat Pumps

All forms of renewable energy has a major role in helping to reduce CO2 emissions and one of the most effective ways of helping reduce our carbon footprint and save our environment is to install an Air Source Heat Pump. Heat pumps have a very minimal impact on the environment (they need electricity to run) however, the heat that they extract from the air, ground or water is constantly being renewed naturally.

Air source heat pumps extracts heat from the outside air in much the same way as a fridge extracts heat from its inside. They work equally well even when the outside air temperature is as low as minus 12 degrees C.

Unlike gas or oil heating boilers, heat pumps deliver heat at lower temperatures over a much longer period. So in the winter they may need to be left on 24/7 in order to maintain and heat your home efficiently.

There are two main types of air source heat pump systems and they are:

Air to Air Heat Pump System

This produces warm air which is circulated by fan/s to heat your home or office. However, this type of system is not generally used to heat hot water as well and is purely for ambient air heat distribution.

Heat from the air is absorbed into a refrigerant fluid which is pumped through a heat exchanger. Low grade heat is then extracted by the refrigeration system, pumped from there through the heat pump compressor unit, is concentrated into a higher temperature useful heat that is capable of heating water for the heating circuits of the home or office.

Air to Water System

This distributes heat via a wet central heating system. Heat pumps work more efficiently at lower temperatures than a standard gas or oil fired heating boiler would. Because of this, they are more suitable for under-floor heating systems or larger radiators, both of which would give out heat at lower temperatures for longer periods of time.
