Kensa Heat Pumps has provided a 21kW Hybrid Twin Heat Pump for Blue Bell Lodge in Devon. Somerset-based renewables installer Total Renewable Solutions (TRS) went to see owners Mr & Mrs Vincent about a replacement heating system. Their old heating system was inefficient and in need of an upgrade or replacement.

Whilst exploring the grounds, TRS discovered that the property had a large picturesque lake at the bottom of the garden fed by a natural spring. This made it an especially efficient water source system for a ground source heat pump, as water is an excellent conductor and has a higher heat transfer rate than the ground. Kensa’s technical team provided relevant calculations which clarified that the lake had sufficient volume and a replenishing energy source from the spring to manage the property’s heat load.

Kensa supplied a 21Kw Twin Hybrid heat pump which provides space heating and hot water to the entire property, replacing the separate heating systems for the main house and annex. Mr & Mrs Vincent are thrilled with the system which has been up and running since June 2015. They have a much greater level of control over the output temperature and are pleased with how quickly the house warms up and retains heat. TRS specified the new system to ensure it was fully eligible for the RHI scheme and also oversaw the application process for the Vincent’s.

Fred Thomson, Sales Manager at Total Renewable Solutions said: “My clients initially seemed a bit sceptical about whether a ground source heat pump would work for them, but once they realised they could harness free energy from the lake to heat their property they were both excited and delighted".
