The FK 2 scratch tube heater and the FK 22 wall-mounted radiant heater both have remarkable performance, which is why they are considered indispensable household accessories. In their case, the FKT 42CM type heating pad supplies the thermal radiation, which, as in the case of all expendable devices, must be replaced at certain intervals. Its qualitatively designed structure is formed by a 42 cm long tube-shaped insert, which guarantees a power of 600 W for both heating elements. Thanks to its beneficial properties, its service life is particularly high and it provides excellent thermal radiation.
