(10 year on body/oil, 5 year electronics). NB: This heater does not come with flex/plug.The ECOGREEN offers a full 24 hour, 7 day digital timer facility, with the ability to schedule 6 changes per day. EOCGREEN also uses electronic'open window' technology to detect temperature drop of 2°C over a period of 5 minutes over a 5 minute period and turn itself off. After 15 minutes, it will monitor room temperature and if an increase is detected, it will switch back onto programmed cycle.
How many elements do I need? As a rough rule of thumb a 10 square metre room requires 6 to 7 elements (660-770 watts), so an EG-07 heater would be recommended for maximum efficiency. You can always lower the thermostat if too warm, a smaller heater will be less efficient as it will be heating for longer periods per hour. (Based on 2.4m ceiling height)-please specify if taller.
