We have the experience and expertise to guide you through a transition to renewable energy. We have highly trained and skilled heating engineers, experienced in providing renewable energy solutions and able to understand your needs and requirements to discuss what renewable energy solution is the best for you.

 

We can service, maintain and install solar panel systems, rain harvesting systems, air to air and air to water heat pumps, ground source heat pumps, bore hole pumps, and all ground source pipework, as well as heat recovery systems.

 

Solar panels use the heat from the sun, not just direct sunlight, so they can still collect energy on even the dullest days, and working alongside a conventional water heater can make a big contribution to your hot water system.

How do air source heat pumps work?

​

There are two types of air source heat pump – ‘air to air’ and ‘air to water’. The Grant Aerona³ uses an air to water system which utilises heat energy captured from the air in ‘wet’ heating system radiators or underfloor heating.

The process uses the same vapour/compression cycle that extracts heat in a domestic fridge. A refrigerant with a low boiling point is exposed to external air temperatures in an evaporator. The liquid boils off to a gas and absorbs the latent heat energy of the air. This gas is then compressed increasing the heat content in the refrigerant, before passing through a heat exchanger where it condenses back to a liquid state while transferring the heat to the water of the heating system. The liquid refrigerant is then re-circulated through the evaporator and the cycle is repeated.
