Andrews provides DHW for award-winning academy in Kent
Energy-efficient water heating for the Leigh Technology Academy at Dartford in Kent is provided by two gas-fired condensing water heaters from Andrews Water Heaters. Designed by BDP, the academy shows savings of 65% in carbon emissions compared to the DfSCF benchmark and a reduction of 30% against Part L of the Building Regulations.
To provide DHW to washrooms, showers, kitchens and teaching areas, BDP specified two Supa-Flo R307 gas-fired ‘constant-flow’ water heaters, together with two 450 litre buffer vessels, They are the largest in the R300 range.
These water heaters have extremely low emissions of NOx, CO and CO2. They are used in an unvented system with an open flue and installed in a custom-built plant room. Their nominal output is 274 kW, which can be modulated down to 20%. Recovery rate is 4700 l/h through 50 K.
