TIPS ON ENERGY SAVING HEATING ECONOMICALLY The boiler is designed to provide a high level of comfort while keeping gas consumption and the resulting environmental effect as low as possible. The gas supply to the burner is controlled according to the level of demand for heat. The boiler continues to operate with a low flame if the demand for heat reduces. The technical term for this process is modulating control.
TIPS ON ENERGY SAVING DRAUGHTS Try to ensure that draughts around doors, windows, letterboxes and keyholes etc. are reduced by using a suitable draught excluder. Warning - Do not block or seal any air vents that are installed to ensure the central heating boiler operates safely. ROOM THERMOSTATS Reducing the setting of the room thermostat by 1°C can reduce fuel consumption by up to 10%. NEW CONTROL SYSTEMS Upgrade your heating control system if necessary with the latest equipment available.
