The innovative large-scale heat pump system installed in the headquarters of Barkwell Plumbing and Heating in Okehampton, Devon, will receive the financial incentive in the form of quarterly payments over a 20-year period.
In order to qualify for the incentive, the design Seasonal Performance Factor (SPF) of the Altherma Flex Type system installed at Barkwells had to be calculated. This was estimated to be 3.0, exceeding the minimum requirement of 2.5. As per ndRHI 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°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.
Robert Barkwell, who heads the family business BJ Barkwell & Sons, says:
“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 in place but we wanted to demonstrate that there is an alternative. We wanted to prove that renewable technology will only benefit our business in the long term.”
“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.”
