Heat radiating power with PTC ceramic insert: 1500 W heating power: approx. 15 m2 thermostat oscillation 2 stages: 750/1500 WPTC ceramic heating element tipping protection built-in handle white color dimensions: core: 21.5 cm, depth: 13 cm, edge: 17.5 cm weight: 1.2 Kg 2 year warranty Features of radiators with ceramic insert: A special ceramic is placed in the heating panel, which functions it does not glow, so its lifetime is almost unlimited. Its material is a special ceramic with different alloys, very long life and low possibility of failure. Its real advantage is that it has a temperature self-regulating feature. The essence of this is that when the heater reaches the set temperature, its resistance suddenly increases. (the resistance changes according to the temperature) Because of this or as a consequence, there is no need to constantly adjust the temperature and there is no need to fear overheating.
