University tennis centre loves Hamworthy boilers
Hamworthy Heating’s long-standing supply of boilers to the University of Warwick continues with the installation of Purewell VariHeat condensing boilers and a Dorchester condensing direct-fired water heater for the new tennis centre.
It has four internal and four external floodlit courts and was partly funded by the Lawn Tennis Association. It has a sophisticated controls strategy involving the amenities area and the main tennis hall, with a natural-ventilation system serving the 2500 m2 hall.
Gerard Hunter, the university’s mechanical engineer, did the mechanical design and specified the boilers and water heater. The building is expected to achieve a BREEAM Excellent rating.
Mr Hunter says, ‘The building has been designed to be 10% more efficient than the minimum requirements in the latest Building Regulations, which will save an additional 17 t of CO2 per annum over and above the requirements of Part L.’
The water heater has a continuous output of 936 l/h based on a 44 K temperature rise. It has a storage capacity of 386 l.
The heating system has a constant-temperature circuit supplying air-handling units in the changing rooms, main halls and ancillary areas of the building. A variable-temperature circuit supplies radiators.
There are two boilers delivering a maximum output of 140 kW at 50/30°C. They have a control system that uses an LPB Bus communications system, simplifying the controls requirement and ensuring close control and accurate load matching.
