Ice Works Apartments, WorcesterKensa Contracting has installed Networked Ground Source Heat Pumps on a new-build and retrofit housing project in Worcester, The Ice Works.JJS Developments Ltd created 54 modern apartments on-site, building several detached apartment blocks from the ground up and converting a derelict Victorian mill-turned-factory that once commercially manufactured ice using an ammonia-based refrigeration process.Project overviewEach newly built dwelling and flat in the converted Ice Works factory features Kensa’s ground source heat pumps, which use sustainably sourced heat from the ground to keep the homes comfortable all year round.Using ground source heat pumps to provide sustainable heating for the apartments feels complementary to the building’s history, as the technology mirrors the refrigeration process used in the Victorian era to produce ice.Key FactsProject start date: 4/11/1954 residential apartmentsPhase 1: 7 boreholesPhase 2: 13 boreholesPhase 1: 23 x Shoebox 3kW Phase 2: 35 x Shoebox 6kW & 1 x 9kW EvoPhase 1: 20-year estimated carbon saving of 11.1 tonnes compared to gasPhase 2: Estimated annual saving of 20.44 tonnes compared to gasAnnual Running Costs: Phase 1: £179 per home per year & Phase 2 £463 per home per yearTotal heat load: Phase 1: 43 kW Phase 2: 80.6 peak kW

In a unique installation project for Kensa Contracting, the historic Taff’s Well – Wales’ only thermal spring – was used as a heat source for heat pump systems in Ffynnon Taf Primary School and the pavilion at Taff’s Well Bowling Club, near Cardiff.Kensa designed a complex but effective open-loop water source system and oversaw innovative horizontal drilling solutions in the installation of the underground pipework. Water source systems are highly efficient, as water has a higher heat transfer rate than the ground. The primary school benefitted from the high heat capabilities of Kensa’s Q (gshp) heat pumps, whilst the bowls pavilion is heated by the efficient Kensa Evo.

Ground source review: Rural Farmhouse RetrofitTwo Kensa 15kW Evo ground source heat pumps (GSHP) were installed to deal with the heating and hot water demands of an old farmhouse conversion with a swimming pool in a picturesque rural farm in the South West of England.

Determined to create a bespoke new build home that ticked all their boxes, Mr & Mrs Babbington installed a Kensa Evo Ground Source Heat Pump to help future-proof their property.In need of a heating system for their new home, Mr & Mrs Babbington wanted to use a low carbon ground source heat pump, because they could see it was the best alternative to fossil-fuel heating, and they knew it would future-proof their property as the UK moves towards a zero-carbon future.The Babbingtons made contact with Kensa sometime before starting their self-build project and formed a good relationship which ran right the way through to when the heat pump was installed, commissioned and beyond.Key FactsTwo-storey, new-build property9kW Kensa Evo40m slinky ground arrayIntegrated solar thermal
