Altherma Flex Type’s Seasonal Performance Factor comfortably exceeds RHI minimum in Devon installation
Daikin UK’s large-scale air-to-water heat pump, the Altherma Flex Type, has become one of the first in the UK to qualify for the UK’s non-domestic Renewable Heat Incentive.
The heat pump system installed in the headquarters of Barkwell Plumbing and Heating in Okehampton, Devon, was calculated to have a design Seasonal Performance Factor (SPF) of 3.0, exceeding the RHI minimum requirement of 2.5. As per the non-domestic RHI guidelines, heat and electric meters were fitted to measure the amount of energy generated and consumed.
The Altherma Flex type system is able to produce water temperatures up to 80 deg C and is suitable for a wide range of applications from schools to hospitals and offices. Systems can be cascaded together to supply buildings with large heat demands of several hundred kilowatts, the manufacturer noted.
Robert Barkwell, who heads the family business BJ Barkwell & Sons, said:
“We were very interested in installing a renewable solution that would provide an opportunity to apply for RHI funding, and we felt Daikin offered the best solution. Mains gas was already installed but we wanted to demonstrate that there is an alternative and to prove that renewable technology will only benefit our business in the long term.”
Stuart Gadsden, Renewables and Heating Product Manager for Daikin added: “We are delighted that air-to-water heat pumps are included within the non-domestic RHI. We hope this will encourage new and current users of the technology to take advantage of the scheme which is currently rewarding renewable heat producers by paying them for the amount of heat they generate.”
