Air Source Heat Pumps

DRG Associates offer a wide range of services utilising renewable energies. We are BPEC registered solar thermal and un-vented solar hot water storage cylinder installers.  We are able to provide a complete service to make your home more energy efficient and help you reduce your carbon footprint.  To discuss your options please contact us

We can supply and fit both air and ground source heat pumps.  These are used to provide hot water or heating (preferably under-floor heating) or can be used with a radiator heating system.  They are powered by electricity and have an energy efficiency varying from 300% to 500% depending on air and ground temperature and generally have a maximum output to water of approximately 55°C.  These systems would normally require some form of backup to produce higher temperatures required for hot water and space heating, this could be in the form of gas/oil/LPG/electric boilers or electric emersion heaters.

Please contact us to discuss your ideas and plans and let us help you realise these.
