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

The ThermoProtec™ 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, preventing condensation of the water vapor contained in the flue gas.
The 280 series ThermoProtec™ valve mixes by-pass 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.
Changeable thermostatic sensor cartridge changes 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.
Wood biomass and condensation build-up
Wood contains a variable moisture content depending on the type (logs, pellets, woodchips, etc.). Water vapor is released during the solid fuel drying phase inside the combustion chamber. The presence of cold surfaces in the boiler or flue gas chimney can lower the temperature of the flue gas down to the dew point, causing condensation. Water vapor condenses on the boiler surfaces, together with soot and part of the unburnt hydrocarbons contained in the flue gas, producing tar deposits.
These substances stick to the walls of the boiler, covering most of the inner surfaces. In addition to being dangerous due to its flammability, tar is damaging to the integrity of the boiler and limits the efficiency of the flue gas-system water exchanger.
By keeping the boiler walls at the highest possible temperature,
the boiler protection valve limits the formation of these substances thereby increasing combustion efficiency, controlling emissions into the environment and prolonging boiler life.
Brass body
The brass body prevents the formation of ferrous residues in the system, prolonging boiler operating life.
Temperature gauge pocket wells
The boiler protection mixing valve body features temperature gauge pocket wells on front and rear sides, allowing installation of a temperature gauge (code F29571) for monitoring the working temperatures: by-pass from boiler, return from system, and mixed
to boiler.

Ordered these heater elements as I had a hard time finding them elsewhere. Received a call the morning after ordering to update me and tell me about possible delays as they had to be ordered. However they were shipped very quickly, and were received within 3 days of order. Thank you.
