Hamworthy brings solar energy to community housing development

Hamworthy
This installation of 63 solar collectors from Hamworthy works with Hamworthy boilers to provide heating and hot water for community housing in east London.

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.
