Truma safety valve Frost Control with John Guest System

The perfect frost protection

The de-energised safety/drain valve automatically drains the boiler if there is a risk of frost. This prevents the drain from freezing up and your water supply is on the safe side.

Function:
The water is drained intermittently via a drain connection in the event of overpressure. If there is a risk of frost, the FrostControl opens automatically and drains the water content of the boiler into the open via a drain connection. The valve can also be opened manually.

Suitable for:
Electric boilers, gas boilers, gas/electric boilers
