Case Study

Location: Failand, North Somerset
Project: Air Source Heat Pump and Solar PV On-Roof & Ground Mount Installation
Value: £15,000
Renewable Heat Incentive per year:
Energy Savings per year:

Our relationship with the National Trust has developed over the last 2 years and the products we offer them have changed too. When we were approached about the redevelopment of an old farmhouse in Somerset in the middle of 2015 we were asked to provide a solution that would reduce the tenants running costs, making the property more attractive to prospective tenants, and a solution that did not break the bank. There was no existing heating system in the property and no mains gas available, so we proposed a split air conditioning system, with an outdoor unit and an indoor unit connected with refrigerant pipework. In order to reduce energy costs further we proposed a 4kW Solar PV system, composed of a 2kW on roof system on one of the farmhouse’s outbuildings and a 2kW Ground Mount system so as not to disturb the look of the main house.

Why they chose us

We have worked with the National Trust for over 3 years now and have developed an understanding where we can provide the highest quality products and installation and still keep to budgets that they are able to allocate, the National Trust are improving the efficiency of their properties not only to reduce costs but because they know they have a responsibility to reduce their carbon emissions. In recent years we have specialised in retro-fitting homes with renewable technologies, from heat pumps to underfloor heating. We have been able to learn about this by working with the National Trust, meaning that now, when it comes to older properties we are able to select the best solution for the application. For this project in particular, we were able to supply a design where only one air source heat pump was required. Heat pumps drop in capacity as the temperature drops, so by choosing a superior product where the capacity does not drop as much as other products we can ensure the buildings heat requirement will be met. In this case, our competitors would have required 2 heat pumps, this increases the cost of install and would limit the capabilities of the system. We work with a number of national suppliers to ensure we can offer the best products, the initial plan was to install PV on the roof of the house, however the National Trust felt this would ruin the aesthetics, so we offered to supply a ground mount, with an on-roof array for one of the outbuildings.

The Results

Commissioned in February, whilst the farmhouse was still a building site, we were able to maintain a comfortable temperature throughout the property whilst the finishing touches were being applied during a particularly cold snap. So the building was able to dry out and absorb some of the heat. Damp had been a problem throughout the life of this property, with new windows and a constant source of warmth, this should no longer be a problem. Each year the National Trust is set to benefit from the Renewable Heat Incentive to the tune of £1,052.30 and the tenants will benefit from savings of over £300 a year.
