Doveton House in Stourbridge comprises of 31 one/two bedroom flats, which are occupied by elderly residents. Historically, the whole complex was heated by electric storage heaters, each flat having two to three storage heaters which were individually controlled by thermostats.
Black Country Housing approached National Grid Affordable Warmth Solutions (NGAWS) to assist with the project of replacing expensive to run electric storage heaters with a gas-fired solution. Following an in-depth analysis NGAWS concluded the site could be served by natural gas and an assessment of personal circumstances showed residents were eligible for the National Grid Fuel Poor Voucher (FPV) as tenants were in receipt of qualifying benefits or aged 70 or over.
NGAWS introduced its approved contractor, GASS Ltd., to Black Country Housing and the partners planned and designed a heat network and installation programme that would provide adequate heating for residents in readiness for the forthcoming winter. GASS Ltd. have installed three highly efficient Vaillant ECO Tec boilers to the central boiler plant. The heat network is controlled by a proprietary boiler management and weather compensation system. Pressurised, pumped and insulated District Heating pipes have been constructed that feed a 'heat' circuit to each floor. The heating circuit on each floor is linked back to the heat management system which will optimise flow temperatures. Each flat and communal area in the complex will be heated by thermostatically controlled radiators. Additional benefits to residents will be the use of a wireless room timer and thermostat.
The environmental benefit of the scheme shows lifetime carbon dioxide savings of 900 tonnes and present value of fuel savings of over £34,000.
