The BMES Minder is an intelligent central heating boiler management system, compatible with most small domestic boilers including combis, condensing and back boilers using natural gas, oil or LPG. In common with all BMES intelligent controls the system uses the principle of Variable Thermal Response (VTR) to achieve it's energy savings. It has two electronic sensors which are fitted to the FLOW and RETURN pipes of the central heating system. Information from these sensors is used to accurately vary the system temperature according to the demand imposed. This significantly reduces the fuel wastage caused through temperature overshoot, heat saturation of the heat exchanger, flue losses and unnecessary boiler cycling, whilst improving internal comfort levels and reducing CO2 emissions. The Energy Minder is also available with an optional weather compensation program (only suitable for heating only or combi boilers).
