A previous installation by another company had resulted in the client being unhappy with the performance, with high electricity bills and cold rooms. RDC were asked to diagnose the problem and found that the system was considerably under-sized.
It is essential to use a company that specializes in heat pumps to ensure an efficient well designed system suited to the property, unfortunately this is not always the driving factor and when price takes precedent often the result is poor design, and an inefficient system.
RDC removed the 8kW air source system and installed 2 x 11kW ground source units taking heat from 5 bore holes located on the drive.
The new system is working very efficiently, providing comfortable heat for the house and 150L of hot water. The owners are recouping their investment in the new system from the domestic RHI over the next 7 years.
