This new biomass system in Pulborough, Horsham, was installed to provide 100% of both heating and domestic hot water and provides 49.182 kwh energy.
The figures are based on a typical heating season with an average room temperature of 21 degrees centigrade and a boiler efficiency of 90%. An oil boiler based on this would cost £3,196.83 and an LPG system would cost £3,688.65.
