Air Source Heat Pumps

Air Source Heat Pumps Lymington, Hampshire, New Forest.
An air source heat pump (ASHP), works in a similar way to a Ground Source Heat Pump except that it extracts heat out of the surrounding air instead of the ground.
Air source heat pumps are compatible with both radiator based and under floor heating systems and can be used together with most electric boilers, oil-fired boilers or equivalent when docking to an existing heating/hot water system.

How It Works

An air source heat pump extracts energy in the form of heat from the outside air in the same way that a fridge extracts heat from its inside. This is the same gas compression refrigeration cycle as a ground source heat pump but this time the energy source is outside air drawn across the evaporator heat exchanger by a fan.

This might sound impossible during the winter months, but given that the refrigerant in a heat pump boils at between -15ºC and -30ºC there is always energy to be extracted from the air regardless of the weather! The key is to understand how to do this efficiently and to understand the limitations of air-source devices in these circumstances and to provide for them.

Savings & Earnings

By installing an air source heat pump you will be eligible for the Renewable Heat Incentive (RHI). This is a government initiative to reduce carbon emissions and reward households who move away from fossil fuels to heat their homes.


Working in a similar way to the Feed-in-Tariff for solar photovoltaic (PV) systems, owners of heat pumps will be paid according to the total heat load of the property in kilowatt hours, for seven years tax-free. Air Source Heat Pumps Lymington, Hampshire, New Forest

TOP TIP If you do not have suitable land area for a ground source system, or have a very highly insulated new build property, or if you want heating for an outdoor pool then an air source heat pump may well be an ideal solution.
