Unipolar and bipolar thermostats for storage water heaters

The rigid rod thermostats operate by exploiting the linear thermal expansion of the rod which, acting on a switch, disconnects the electrical circuit positioned in the thermostat head. It is also possible to opt for our model with a patented double safety system with manual reset, which, by means of a bimetallic disc, ensures the permanent opening of the two phases of the electrical circuit. Alternatively, the permanent opening of the two phases can also be ensured with the traditional bimetallic disc system.
Furthermore, our heating elements guarantee the safety and correct functioning of the water heater.
The standardized production, the computerized calibration systems and the strict controls allow RECO to ensure the highest level of quality and safety for its thermostats.
