Installing a HeatingSave controller can save between 15% and 25%+ off fuel usage, providing a shorter payback period than changing a boiler or installing double-glazing. HeatingSave comes complete with PC software that allows you to check and monitor the temperature of the rooms within a building and heating system itself. Once installed, HeatingSave automatically day-by-day improves the energy efficiency of a central heating boiler, significantly reducing the cost of heating bills.
