Here at Underfloor Heating Systems Limited we use Reliance Water Controls underfloor heating mixing valves for our wet underfloor heating systems.

The underfloor heating pump is made by Grundfos.

The underfloor heating mixer is the ThermoMix mixing valve, one of the best mixing valves on the market.  The underfloor heating mixing valve can be mounted to the left on the underfloor heating manifold or to the right on the underfloor heating manifold.

The control pack that consists of the underfloor heating mixer and the underfloor heating pump can do up to 14 Kw underfloor heating output.

If the property is built to current building regulations, the underfloor heating pack could do up to 180 – 190 sqm floor area, ie 1000 m of multilayer pipe.

It is important that the pipework from the heating source to the underfloor heating mixing valve is flushed, as else there is a risk of dirt entering the underfloor heating water mixing valve and this could cause poor flow rates to the water underfloor heating manifolds.

The underfloor heating mixer can be adjusted from 35 degree C to 65 degree C.

The underfloor heating pump is a 25/60 pump, this is the same as a 15/60 pump.  The only difference is that our underfloor heating pump is black and the normal Grundfos pump on the market is red.  The reason for this is that our black underfloor heating pump is only sold to OEM’s and the red Grundfos pump is sold to merchants.
