The brief was for a clean, sustainable heating system and our solution was a Danfoss DHP-L Opti 10kW heat pump, drawing energy from 2 boreholes at 88m depth. Heating is via underfloor heating throughout the building, which we also installed by Lee and Andrew ex-owners of Coefficient Renewable Heating Solutions and now Technical Systems Engineers for IMS Heat Pumps.
Case Study Facts:
- Danfoss DHP-L Opti 10kW heat pump
- 2 boreholes at 88m depth
- Heating-only system
Case Study Results:
- Annual fuel cost savings of 35% compared to alternative oil-fired system
- Annual RHI income £1100 per annum (paid for 20 years)
- Carbon dioxide emissions reduced by 1,862kg per year
