Air Ground Source Heat Pumps Devon, Solar PV, Biomass, Wood Burning

All heat pumps are an extremely efficient way of delivering a dwelling its heating and hot water demand if designed correctly.

Very simple to retro fit to an existing system and a great choice for any new build project.

If a property has photovoltaic panels installed heat pumps are a very good option as you can use the electricity being produced to offset the running cost of the heat pump… in some cases for free over a 12 month period.

Heat pumps are generally at least 3 times more efficient to run than a conventional fossil fuelled system.

Heat pumps come in two main varieties:

Air Source Heat Pumps (ASHP)

The ASHP is sited in the garden or mounted to a structure. It works by using a refrigeration process similar to a domes4c fridge.

At home the back of the fridge is always warm and inside is cold. The heat pump operates in the same way but instead of retaining the cold it expels it by blowing it away using a fan and retains the heat. The heat is then put through a heat exchanger and pumped into the building to provide heating and dhw.

The ambient air temperature is the source of heat to start the refrigeration process. The efficiency of a heat pump fluctuates throughout the year depending on outside air temperature and demand on a property. This can be calculated on system design.
