This air source heat pump system has been designed and installed to replace an old oil fired AGA with back boiler. Due to the existing radiators not being capable of working at the new design of temperature of 45˚C, all the existing emitters were replaced with new Stelrad K2 radiators with thermostatic valves. In addition to the radiator upgrade the kitchen was fitted with a Myson kick space heater due to the limited wall space and the conservatory is heated with a Dimplex Smartrad (Fan assisted).
The system is controlled by the new Mitsubishi FTC5 controller with weather compensation and the MELCloud for access via the internet or your smart phone.
In addition to the Mitsubishi Ecodan W85 air source heat pump 4kW of Solar PV was also fitted using the latest Solar Edge technology with micro inverters. The PV on average reduces the running cost by a further 25%. It is expected that the customer’s annual fuel bill will be reduced by 70%.
Not only are the fuel savings huge but the customer is also entitled to the FIT for PV, netting nearly £20,000 over the next 20 years and the Domestic RHI payments totalling £6388 over the next 7 years.
