Mixing Valve, Pump & PEX Manifold for lower Temp Radiant Systems

Taco Mixing Valve setup with a Grundfos pump to a 4 Port PEX Radiant Manifold. This will allow you to run lower tempeatures to your radiant that what your boilers is putting out. In this case - we set the tempeature guage to 120 Degrees and if the boiler runs over this - then all you will get is max 120 Degrees. If the boiler is running lower tempeature - then the floor will get this lower tempeature.

When using any Mixing Valve you want to make sure that the pump is pulling water through the mixing valve. Mixing Valves are used frequently in PEX Radiant Heating Systems where lower water tempeature is needed.
