Project to upgrade existing heat pump and electric heaters for swimming pool, spa and air heating on 50m³ indoor leisure pool.
We first removed all of the existing equipment and supplied and fitted a new Mitsubishi ECOdan heat pump and ancillary equipment.
The Mitsubishi heat pump operates on a primary circuit to a 300 litre buffer tank and a secondary circuit from the buffer tank is connected to three heat exchangers managing all the heating needs of the facility.
Separate temperature controls are fitted to the heat exchangers to allow individual control of each, with the pool set to 29°c, spa set to 38°c and air heating at 32°c.
The upgrade has given the client a single heat pump rather than running two fixed speed and now inefficient heat pumps and separate electric heaters.
We repurposed the electric heaters within the new arrangement to provide emergency back-up if ever required.
At present after several months of running we are achieving a SCOP of 4.1, and with some more fine tuning on the weather compensation curve we are confident of getting an even greater energy efficiency.
