Case Study – Barn conversion, renewable energy

Location – Crewe

Existing situation and objectives

As always we carried out a thorough consultation with the clients before scoping the work to determine their objectives – which included greener energy with the added peace of mind of static energy bills going forward. As the property is a barn conversion the clients wanted to be self-sufficient and explore cleaner, renewable options right from the start rather than installing a traditional energy source. After agreeing on a solution based on their requirements we then conducted a full design and scope of the project including all heating products, costing the overall work accordingly in line with the clients’ budget and objectives.


Initially before any work began we carried out a structural survey for the heat loss calculations, plus a British Geological Survey for the boreholes to ascertain the correct depth for the pipework. We then designed the heat emitter circuits based on the heat loss calculation in order to obtain the correct Delta T on the flow and return temperature. Additionally we carried out the application for the MVHR based on the building’s air tightness; and this has greatly improved the heating performance thus reducing the client’s heating bills in a significant way.

Following the initial groundwork and preparation a Ground Source Heat Pump was then fitted with two 130 metre boreholes, whilst underfloor heating for the whole house and Mechanical Ventilation Heat Recovery systems were put in place to compliment the new energy-efficient technology. We have also installed the first and second fix heating and plumbing.

During the course of this project we collaborated with other engineers and consulted closely with the client at each step of the way to make sure the installation continued smoothly and efficiently throughout – and this close communication helped to save time and money. As a result the work was completed within six weeks.

Outcome and benefits

The client now has a clean, energy-efficient environment in which to live which has been carefully configured to enable them to save money both now and going forward. The installation has reduced the property’s CO2 emissions and has resulted in lower energy bills almost immediately – in addition to allowing the client to gain money from the RHI (Renewable Heat Incentive) application.
