Ground Source Review: Hanover, Ashfield Court

Ashfield Court is a two-storey block of 22 flats with one site office, constructed in 1977. Following energy efficiency measures including  loft insulation, cavity wall insulation and double glazing, Hanover opted to retrofit ground source heat pumps in place of the ageing night storage heaters to further lower tenant heating bills and improve the building’s efficiency.

Winston Williams, Property Director at Hanover Housing Association said:

Hanover were keen to adopt district ground source heat pump technology into our housing stock as we felt it provided a cost effective and long-term solution, and means residents will save money on their heating bills as a result. As well as being able to monitor running costs and ensure the systems are performing efficiently, the new scheme will save nearly 1,900 tonnes of carbon emissions during its lifetime, so it really is a win, win for everyone.

In total, twelve shared ground loop array systems were installed for the 22 flats with a separate system for the office. Each array consists of two flats sharing one borehole. Within each flat is a Kensa 6kW Shoebox Twin heat pump and new 150 litre unvented hot water cylinder in the airing cupboard.

It is expected that, on average, each tenant will save £352 per year on their fuel bills.
