  • Mixing Valves - Watts

    Mixing valves used in heating systems allow the boiler to be operated at higher temperatures which will prevent the growth of Legionella in the standing water and extend the effective system flow rate. A mixing valve can also help reduce the size/BTU requirements that are needed to provide capacity during peak system demands.
