Splitting of UFH and Rads via Stat

[Mason Carter]

I think that the pipe which is a Y shape ie comes from boiler splits down to the UFH up to rads is heating flow (what boiler is it) a 2 port valve would need to be put in the leg that goes to rads (after split).Have you got a photo of UFH control unit.

It's a combi. The UFH is an Emmeti ewc-1... i've got this picture but access is cramped here.

You will have to get a plumber to check what combi is it ?

In the boiler for the heating you should have terminals for a stat eg L and Rt from stat a two core & E cable/flex would need to be connected between this and the volt free boiler terminals in UFH wiring ctr. when a valve is fitted to leg for rads the orange and gray will go between the room stat terminals in the boiler. The brown to open the valve goes to 3 in the wireless stat link between live and 1.

You could try backing the flow control valves back on each of the UF manifold zone valves effectively starving the ground floor and forcing flow to the rads. Ideally move the stat upstairs. This will require a lot of tinkering with flow rates but may at least get you some heat upstairs in the short term.

As already said the real answer is to split the zones.

What did you decide to do in the end ?.
