Description

ThermoMix High-Flow Boiler Protection Thermostatic Mixing Valve, Cartridge Sensor

The ThermoMix boiler protection high-flow thermostatic mixing valve is used in hydronic heating systems with non-condensing boilers, including solid fuel, biomass, gas, LP or oil-fired. It can be installed with steel, cast iron and copper tube style boilers, automatically controlling the return water temperature, preventingcondensation of the water vapor contained in the flue gas.

The 280 series ThermoMix valve mixes bypass flow from the boiler with return flow from the system, sending a fixed temperature flow to the boiler which protects against corrosion from condensation occurring when a minimum flue gas temperature is not otherwise maintained.

Changable thermostatic sensor cartridges modifies valve temperature setting. The thermostatic sensor cartridge can easily be removed for maintenance or to change the valve set temperature, with out removing the valve body from the piping.

I would buy this product again

I purchased and installed one of these in 2016 and it's worked faultlessly to this day. I dropped it one star simply because of price. It's expensive, but much cheaper than running a traditional boiler ineffectively, and given that so many boiler installations are oversized this could be the best thing you could do, if you are in that situation. It worked for me.
