Northamptonshire Extended Cottage save with Solar PV and Heat Pump

09 November 2015Air Source Heat PumpSolar Photovoltaic

Mr & Mrs S live in a Northamptonshire 17th century cottage which also has a large extension. Their existing storage heater system was insufficient in comparison to the size of the cottage. Bright Green were called and proposed a 13 panel east-west solar PV along with a 14kw Daikin Air Source Heat Pump and Hydrobox and new radiators throughout.

The Solution

Bright Green Vechicles Bright Green surveyed the cottage and carried out a detailed heat loss report to ensure the correct sized heat pump and radiators were installed, and also to find the most productive solar PV array.

It was proposed that the heat pump would be located at the side of the property to allow full capacity, the settings were put into weather-compensation mode to allow maximum operation and reduce running costs, the hydrobox would also be out of sight in the converted loft space.

A 200l unvented hot water cylinder was to be installed into the airing cupboard at the top of the stairs and all new pipework throughout the installation. The solar PV would be installed on the East & West elevations.

The Installation

The completed heat pump system At the beginning of November 2015 Mr & Mrs S had allowed the Bright Green team full access to their property while they were away on holiday.

The installation began with the installation of the solar PV, with the brackets, rails and panels all being installed on the first day, the electrical connections were finalised the day after.

The team then de-commissioned the storage heaters and took delivery of the radiators, heat pump, cylinder and hydrobox. All radiators were mounted onto the walls where the customer had requested and a route was chosen for the pipework radiators.

The hydrobox was mounted in the converted attic space, while the cylinder was installed into the airing cupboard, the hydrobox was connected to the cylinder and the heat pump mounted outside, the refrigerant pipework was then connected from the heat pump to the hydrobox.

On day five the team commissioned the new system and the cottage had hot water and was warm and toasty in time for Mr & Mrs S returning from their holiday.

The Benefits

Solar PV Mr & Mrs S had said they wanted to save on their energy bills as the storage heaters were costing a small fortune and took a long time to heat the cottage.

After speaking to the customer a month or two later they had advised that their energy bill had been reduced by over 50%, this will only get better as the solar PV will be generating a lot more as the winter months are put behind us. Mr & Mrs S have said they are thrilled with the installation.
