The Challenge

The building was previously heated with three existing commercial gas boilers that had come to the end of their life, so Dorset House was identified as one of the buildings to focus on as part of a decarbonisation plan.

Dorset House sits at the heart of the Talbot Campus, where most of the undergraduate and postgraduate courses are delivered at Bournemouth University.

The building is where the Forensic Toxicology, Scanning Electron Microscope (SEM) and Microscopy labs are based, as well as a range of industry-standard analytical instruments. This building is also home to the Business School’s Professional Engagement Suite.

The Solution

Nine CAHV-R air source heat pumps from Mitsubishi Electric have been installed in a special compound to replace the gas boilers. The CAHV-R units can deliver domestic hot water up to 70°C, which will be used for both heating and hot water throughout Dorset House.

The CAHV heat pump has been one of Mitsubishi Electric’s most popular commercial heating system since it’s entry on the market over a decade ago. The latest version, the award-winning CAHV-R uses lower Global Warming Potential (GWP) R454C refrigerant, to deliver a robust, low carbon system for the provision of sanitary hot water and space heating.
