Emmeti UK | Heating Manifolds (T3)
Diagram showing a mixed heating system
Type 3 (T3) manifolds are for underfloor heating (UFH) systems only. They have a temperature controller and pump, to ensure that the water is at the correct temperature for the underfloor heating circuits, and there is sufficient flow for the greater amounts of pipe used.
Within this simple explanation of the type are many variations and applications, ranging from stand-alone control groups, like the T3 Controllers, to T3 Floor Mixing Units which are fully pre-assembled single piece ‘plug and play’ sets, to more complex primary distribution groups, like Firstbox Primary Flow.
Within each range are further variants, reflecting the needs and sizes of underfloor heating systems, from domestic to full commercial civil construction, with different flow and temperature requirements. On temperature management, these range from simple hydro mechanical mixing valves to full weather compensating packages.

Mixed systems – controlling both wall hung radiators and underfloor heating with manifolds:
Emmeti T3 Floor Mixing Units are designed to work with both a high temperature set of circuits (wall hung radiator circuits running at in excess of 60°C) and low temperature circuits (underfloor heating pipe running at temperatures lower than say 50°C). You can add high temperature circuits to the left hand side of the Floor Mixing Unit, please look at the high temperature T2 rails that are needed, under Floor Mixing Unit Accessories. We also advocate using Heating Manifolds (T2) for wall hung radiators, perhaps on the 1st floor of a domestic property, with a T3 manifold for the ground floor in screed underfloor heating pipe circuits.
