Devices for Preventing the Boiler from Over-heating

1. Thermal Discharge Safety Device
When 100 °C is reached, this device opens a valve and sends
cold water to the safety heat-exchanger in order to decrease
the temperature.
2. Safety Temperature Limiter
Switches off the blower fan at the maximum boiler temperature
of 105 °C. The pumps continue to run.
Once the temperature has fallen to under approx. 95 °C,
the safety temperature limiter 10 can be unlocked
mechanically.
3. Safety valve
Protection against over-heating:
When the boiler pressure reaches approximately 3 bar, the
safety valve opens and the heated water is blown off in the
form of hot water or steam.
