Whether in closed heating systems, underfloor and collector heating, or in electrically or gas-heated instantaneous water heaters: Do not take any risks with hot water preparation and rely on the reliable protective function of this safety temperature limiter. The limiter immediately shuts down the heating system when the preset safety temperature is reached. The reactivation of the cooled heating system is only possible after the manual release of the limiter. Comes with ENEC certification and CE marking.
