Efficient, low carbon school heating
A hybrid commercial heating system from Ideal Commercial Heating, featuring ECOMOD heat pumps and Evomax 2 boilers, has been installed at Hawthorn Primary School in Doncaster.
The school campus comprises several buildings of varying ages and construction types, creating challenges for consistent temperature control and system performance. The existing heating infrastructure, which consisted of two ageing openflued boilers alongside undersized pipework, struggled to meet demand efficiently, resulting in high gas consumption and unreliable comfort levels, particularly during colder months.
Longstanding Ideal Commercial Heating customer Service 2 (HVAC) was appointed to design and fit a new system capable of delivering dependable year-round performance while reducing carbon emissions. The completed installation is a hybrid system with two 50kW ECOMOD 290HT air source heat pumps and three wall-mounted Evomax 2 150kW commercial condensing boilers operating in cascade, providing 450kW of output.
The heat pumps are located externally next to the plant room and feed buffer vessels, while the boilers are installed internally on an Ideal Heating frame and header kit, with preformed insulation kits and a plate heat exchanger to ensure separation between the primary and secondary circuits. This allows the heat pumps to satisfy most of the school’s heating and hot water demand, with the boilers automatically providing support during periods of lower external temperatures. www.idealcommercialheating.co.uk
