Mixing units for underfloor heating
Flooré mixing units
If the underfloor heating is connected to an existing water-based heating system, such as radiators, a mixing unit needs to be installed.
The mixing unit pumps water around the underfloor heating coils and mixes most of the cool return water from the underfloor heating with incoming hot water from the radiator system. If the mixing unit is not used, the water temperature will be far too high. Water-based underfloor heating is what is termed a low temperature system, which means that the flow temperature is significantly lower than would be required for conventional radiator systems.
