Knob Setting Central Heating Radiator Temperature (approx.) Minimum 45ºC Maximum 80ºC For economy setting ‘ ’ refer to Efficient Heating System Operation.
6 EFFICIENT HEATING SYSTEM OPERATION The boiler is a high efficiency, condensing appliance which will automatically adjust its output to match the demand for heat. Therefore gas consumption is reduced as the heat demand is reduced. The boiler condenses water from the flue gases when operating most efficiently. To operate your boiler efficiently (using less gas) turn the central heating temperature knob (B) to the ‘ ‘ position or lower. In winter periods it maybe necessary to turn the knob towards the MAX position to meet heating requirements. This will depend on the house and radiators used. Reducing the room thermostat setting by C can reduce gas consumption by up to 10%.
