Immersion heating device that could be used particularly in a water circulating heating radiator

摘要

The thermal insert consists of a heating cartridge (3) within a sealed tube (1) which contains a heat carrying liquid (2). The cartridge includes a resistor (5), thermal cut-out (8) with parallel resistor (9) to maintain a cut-out operation until water circulation is restored and a fuse (12) to protect against electrical faults An Independent claim is made for a radiator which uses the thermal insert
