isoenergy was asked to design a system that would respect the building and heat the section currently lived in my the owners. A number of options were available for providing heating, but the near by lake was a perfect heat source for a ground source heat pump.
Spatial heating and hot water are provided by two 45 kW water source heat pumps, with energy collected from a near-by lake using a closed-loop array of 3,000 metres.
To supplement the ground source system a solar PV array was designed and installed by isoenergy. The solar photovoltaic array generates enough revenue throughout the year to offset the running of the heat pumps.
To make the most of the free energy from the sun, a solar thermal array was installed on a flat roof hidden from the ground by the building's parapet.
