The Truma FrostControl Kit with John Guest fittings is designed to help protect compatible Truma water heating systems against frost damage. The FrostControl valve automatically drains the water from the boiler when temperatures fall to a critical level, helping to prevent frozen water from damaging the system.
The valve operates without an electrical supply and automatically opens at approximately 3°C. Once the ambient temperature has risen sufficiently, the valve can be manually closed again and the water system refilled.
Supplied with John Guest push-fit connections, the kit provides a convenient solution for integrating FrostControl into compatible water systems. It is particularly useful for caravans, motorhomes and campervans that may be exposed to low temperatures during colder months.
Compatibility should be checked with your existing Truma heating system and plumbing configuration before ordering.
