Ceramic heaters achieve higher temperatures than most panel heaters - allowing them to heat a large area with greater intensity. The thermal conductivity and its heat retention make this heater very efficient to run. Even when switched off, the ceramic heater will continue to radiate heat due to the residual warmth stored in the ceramic plate.PROGRAMMABLE LCD DISPLAY: This MYLEK panel heater is super simple to use. By using the LCD control, you can easily set your desired hourly/daily/weekly time and temperature that you would like your heater to reach, as well as choosing between 3 different heat modes (one of which being frost protection). The child lock function prevents the heater from being tampered with and the LCD also dims for night-time use! Height 45cm x Length 88.5cm x Depth 11.5cm, Weight 11.6kgs, Room Coverage: 20m2 - 25m2.
