The FMU3 (Floor Mixing Unit 3) is a pre-assembled competitively priced manifold designed to simplify the installation of underfloor heating systems.
Included in the FMU3 is a TM3 Thermostatic Control Group complete with Grundfos UPM3 circulating pump, temperature gauge, mounting brackets and swivel joints for connection to the manifold assembly. The TM3 thermostatic mixer ensures that hot water from the heat source and return water from the underfloor circuit are mixed together in the valve body to produce a range of temperatures from 20°C to 70°C. This range of temperatures suits a wide range of underfloor heating applications, from commissioning new floor screeds to operating with very thick floor screeds in commercial applications.
Available from 2-12 way.
