The owners of Paxton Green Group Practice needed a heating solution that would future-proof the building by reducing both heating bills and carbon emissions, to replace the existing gas boilers.

Ecodan CAHV monobloc air source heat pumps from Mitsubishi Electric were chosen due to their ability to lower running costs and carbon emissions. Patients and staff can now benefit from cost-effective, renewable heating while also enjoying modern levels of comfort.

The heat pumps were installed to deliver 116kW of heat to the building, replacing the two commercial gas boilers. The CAHV models operate in a cascade system, meaning they are able to continually match the heating but only consume the power needed to keep the practice comfortable, whatever the weather.

Andy Booth, project manager for Opus Air Conditioning, which installed the system said: “One of the things that amazed me was how quickly the CAHV units heated the water in the tank. We picked up water temperatures of 70 degrees in less than 30 minutes.”

Opus specialises in the design, supply, installation, service and maintenance of boilers and heating systems, along with heat pumps, air conditioning and ventilation systems. This was the first Ecodan CAHV installation that Opus had carried out and they will be looking at promoting the use of air source heat pumps on future projects.

Owing to the practice being a vaccination centre for its local community, the heat pumps had to be installed and the old systems removed in close partnership with the practice and its opening times.

“The team had to be completely flexible so that we could get in around the working hours of the vaccination centre,” added Mr Booth.

Heat pumps are low maintenance and able to produce an average of three kilowatts of heating for every kilowatt of electricity consumed. The practice can now provide a high quality healthcare service for patients whilst also delivering high levels of comfort.
