A Building Energy Management System (BEMS) from HeatingSave will provide a platform for running a solar renewable set-up. BEMS is a comprehensive solution for cutting bills by up to 30% and dramatically cutting the environmental impact of heating your business or home. Firstly the HeatingSave controller makes calculations using its internal algorithm to get your boiler and central heating set-up working as efficiently as possible. The BEMS can also be tailored to control a SolarSave solar water heating system, which uses free energy from the sun to provide hot water even in cloudy weather, supplementing and saving on fossil fuel use. This will drastically reduce your building's CO2 emissions.
