Hamworthy brings solar energy to community housing development
Renewable energy for hot water and space heating for a community-housing development in Plaistow, east London, is provided by 63 ModuSol solar collectors from Hamworthy Heating. The building comprises 57 housing-association and shared-ownership dwellings.
Ecogale Services, M&E contractor for the project, approached Hamworthy Heating for a compact solution that was simple to install. Through Hamworthy’s technology-partner programme, the solar collectors were installed by one of its approved installers, Natural Power Wales.
The solar arrays provided pre-heated feed water via six Hamworthy Powerstock PS 1000 calorifiers. The solar energy is complemented by three Purewell Variheat 180 kW gas-fired condensing boilers, including a boiler sequencing cascade controller, to supply heating and top-up for the hot water when demand is very high.
Operating as a fully pumped system, a series of risers from the basement plantroom to the top floor each serve five or six flats via an hydraulic interface unit in each dwelling, which acts like a combination boiler.
