Thermostatic mixing valve for boiler protection against acid corrosion.

Acting temperature: 130°F - 55°C

Protect boiler inner wall from condensation. The exhaust gas will condensate in acid water when the heating return is less than 130°F. Acid water on the inner wall will reduce greatly the boiler lifetime.

1-1/4 thermostatic boiler protection valve

Valve was easy to plumb in once I understood how it worked. Did not come with any kind of instructions, MBtek website has a diagram of how this worked. Basically, AB port goes to the boiler intake (mixed water), and the water exit (heated water) gets piped to B port this forms a loop until the mixing valve begins to open A port (cold water). This prevents the boiler from running to cold which can cause an acidic condensate from the pellets burning, which over time will eat your boiler from the inside out. Be sure to install this to protect your investment.
