Farmhouse Renovation

Members of our team helped a family develop their home on this self build project. They completed a full scale renovation of an existing farmhouse and conversion barns to form one dwelling with a large floor area of 450m2.

This project was situated on the southern slopes of Dartmoor in the heart of South Devon countryside. This particular area is off-gas, meaning the original farmhouse had no heating system apart from open fires to provide heat.

Despite this property being a country farmhouse there was limited space surrounding the property making it unsuitable for a ground source heat pump. The size of the property therefore meant that the heating demand was significantly greater than our typical air source heat pump installations.

Our design calculations identified a 20kw heat demand, we then specified a Mitsubishi Ecodan air source heat pump cascade system consisting of two 14kW Ecodan heat pump units with a 300L Kingspan stainless steel hot water tank, to supply sufficient volumes of hot water.

This cascade system meant that we were able to help our clients overcome an issue with the electricity supply, whilst they benefit from the heat provided by multiple air source heat pump units, with the simplistic controls of only one.

Our clients specified that they wanted underfloor heating throughout the majority of their project, which comprised of different floor constructions and levels. In the few rooms that radiators were installed, the client specified that they wanted antique stylised radiators.

We created a full heat distribution design and installed underfloor heating with 150mm pipe centres and a screed infill on the ground floor. On the first floor we installed underfloor heating with a timber suspended floor with screed infill, to help provide a superior thermal performance.

We then worked alongside the client to identify the correct sizing of their chosen radiators to ensure the system would run efficiently, and therefore minimise energy bills. Our client was extremely happy with this installation.
