Heat pumps are sole source of heat for new primary school

Heating and hot water for this new school in Warrington is provided solely by Mitsubishi Electric air-source heat pumps.

Air-source heat pumps provide heating and hot water for a new school in Warrington — without any support from gas-fired boilers. The £4.3 million Chapelford Village Primary School is a low-impact design that uses a host of energy-efficient technologies such as lighting control with absence detectors and mechanical heat-recovery ventilation.

Heating, cooling and ventilation for the 2219 m2 school, which has 14 classrooms, was planned by BCM Consulting. Matthew Hakes of BCM explains, ‘We used advanced energy-modelling techniques to determine that the optimum energy solution for heating this building was to use air-source heat pumps. Following further analysis, we arrived at the conclusion that a Mitsubishi Electric system would provide the best technical solution for this application.’

The Ecodan CAHV system was installed by A&B Engineers and offers heating and sanitary hot water up to 70°C. The installation can deliver 172 kW of heat at an outdoor temperature of 3°C. Drop off is minimal down to -20°C, including defrost. 69% of the energy delivered is renewable.

There is a gas supply, but only for the kitchen area.
