Barn Conversion, Honeybourne, Worchester

Following over 30 years spent living abroad, Steve and Beverley Mullins recently returned to the UK and bought Middle Barn in the village of Honeybourne in Worcestershire. They renovated the barn and outbuildings to create a large, five-bedroom home.

The outbuildings had been previously used as an office and utility room to the neighbouring cottage and was heated by Calor gas .The barn itself had been partly renovated, but Mr & Mrs Mullins employed contractors to do a full scale renovation/conversion . The property is in a rural area, off the gas grid and the couple were looking to invest in a more sustainable form of energy. A friend recommended Luke Bernardini from Solo Heating Installations as he had installed a NIBE ground source heat pump for them and they were more than satisfied with the service.

The solution

Luke visited the property and recommended two F2040 12kw air source heat pumps from NIBE to provide heating and hot water for the barn conversion.

The NIBE F2040 is an intelligent and compact inverter-controlled air source heat pump, which provides optimum savings as the heat pump automatically adapts to a home’s heating requirements all year round. The heat pump works down to an outdoor temperature of –20°C whilst still providing sufficient hot water and the perfect indoor climate.

NIBE’s air source heat pumps can be coupled with various accessories, such as comfort cooling and ventilation. All these accessories can be controlled via the heat pump app NIBE Uplink. This allows the connection of a home’s heat pump to a smart home system, making it even smarter and optimising its operation.

Solo Heating Installations installed underfloor heating throughout the upstairs and downstairs of the 4,000 sq ft property. The Mullins family also have a rainwater harvesting system to enable them to capture and recycle rainwater. The renovations at the brick-built property included adding new floors, new electrics and windows, plus 200mm thick insulation to ensure the building was as energy efficient as possible.


The Mullins’ system is expected to achieve a seasonal performance factor of 3:1. When you consider this, plus the income from the RHI, the heat pump should pay for itself in just three to five years.

Mr Steve Mullins said: “We’ve not had the heat pump installed over a winter season yet, so we can’t give an exact idea of energy and cost savings yet, however we are delighted with its performance so far. Solo Heating Installations came highly recommended and we were very impressed with Luke and how he was very responsive to our requirements. He was also very attentive to detail, particularly with regards the aesthetics in the plant room. We’re really pleased with the result.” He adds: “It is reassuring to know that we have a heating system that is sustainable but affordable for the future too.”

Luke Bernardini from Solo Heating Installations said: “This was a really enjoyable project to work on and Mr and Mrs Mullins will benefit from a comfortable warm home, through a heating system that is affordable to run and sustainable too.”
