Underfloor Heating Manifold - OMNIE | The Whole House System

OMNIE Manifolds

The manifold distributes the primary warm water into each underfloor heating circuit. The manifold is the central point for the underfloor heating system. It brings together the warm water feed from a heat source, the pipe work from the floor and the thermostat wiring.

A manifold can serve areas up to 200m2 but installation is easier if a manifold is installed in an accessible central location on each floor. The size of the manifold depends on the area it is serving.

Manifold with mixing unit and circulator:

The manifold is supplied with a mixing unit and circulator to ensure the water temperature entering the floor does not exceed the design temperature. This manifold configuration is essential if the heat source is able to supply high temperature water.

‘Branch’ manifold:

Again, if the water is only supplied at the correct temperature then the mixing valve is unnecessary. Also, if there is a primary circulator installed then this  can be removed from the manifold assembly.
