The Igenix Over Door Downflow Fan Heater offers efficient functionality whilst utilising a self-regulating PTC heating element, which can be more energy efficient than other types of heating elements. The open window function avoids energy being wasted by monitoring the temperature in the room and entering standby mode if the temperature decreases while heat is being emitted. For ultimate organisation, there is a weekly programme function that enables you to set the heater to turn on and off at specific times each day, or you can simply use the 24 hour timer to turn the heater on or off at a more convenient time in the future. Use the LED display or remote control to easily control the heaters functions, including 3 modes and 2 heat levels. This heater also has a fan function to keep you cool in the warmer months, making it an essential addition to your home all year round.
