High fuel prices means high oil prices for central heating — and just in time for autumn and winter too when it's most needed! HeatingSave can save oil central heating customers £100s off their annual bills. The longer HeatingSave has been installed, the more it saves as the microprocessor continually refines its mathematical thermal algorithm of your property. HeatingSave's PC software displays how much your heating is costing. For those with oil-fired systems it predicts how much oil is left in the tank.
