Manifold connection to boiler, heat pump or district heating

Connecting underfloor heating is skilled work. We fit the manifold, connect the circuits to your boiler, heat pump or district heating and make sure everything is flushed, vented, pressure-tested and balanced — even if someone else installed the underfloor heating.

Everything from one teamInstalling, fitting the manifold, connecting, pressure testing and balancing — all by the same team.

Benefits

Connecting and balancing underfloor heating

  • Connecting the underfloor heating manifold — to a boiler, heat pump or district heating, with a pump group or mixing unit where needed.
  • Flushing & venting the underfloor heating — every circuit thoroughly flushed and fully vented — air is the main cause of cold spots and a ticking pump.
  • Pressure testing — the whole system pressure-tested before handover.
  • Balancing the underfloor heating — dynamically: flow meters per circuit, pump and supply temperature set — every room evenly warm.
Good to know

For our milling and wet-system jobs, connection is included in the quote as standard. Is your underfloor heating already in place? Then we also come just to connect and balance it — and a manifold that doesn't heat properly or ticks, we get working again. We don't work on the gas installation itself.

Connecting underfloor heating in practice

Manifold mounted upside down on the boiler: the circuits come from the ceiling, so the manifold follows.

How it works

How we connect your underfloor heating

Four steps, finished the same day.

1

Fit the manifold

Every circuit neatly connected and labelled.

2

Connect to the heat source

Boiler (with mixing unit), heat pump or district heating.

3

Flush, fill & vent

Circuit by circuit, then pressure-test.

4

Dynamic balancing

Flow meters, pump and supply temperature set.

Existing floor and no new screed? Then milling in underfloor heating is the smartest solution: no loss of height and no drying time.
