Following the initial enquiry, J L Phillips carried out a full room by room heat loss calculation on the Office block This determined the room requirement for space heating in Watts per m2. Radiator sizing was designed to ensure that the temperature of each room (21 degree Centigrade) was achievable at an external temperature of – 3 degrees Centigrade.
Heat pump sizing was achieved by calculating the total watts required for space heating with an additional hot water requirement for the 15 showers in the changing room block.Third party heating controls were installed, and a split zone design was implemented to separate the shower block from the office block and split the ground floor from the first floor.
3 x Mitsubishi CAHV 42kW Monoblock heat pumps were specified, giving a total output of 126kW’s.
With a seasonal coefficient of performance up to 3.54. The installation and upgrades to the heating design will look to save not only on carbon emission but also on-going fuel bills.
