2 zone under floor heating. Does the pump need to be fitted to manifold

[Dharlen]

This is my first post and need help with underfloor heating.

I have just had an extension built with the floor area for this room now circa 24m2. This room is going to run underfloor heating on its own zone. Rest of the house is rads.

System has been installed and just waiting for room stats to arrive so insulation can be completed.

After the plumber left I had a look at the manifold and noticed that the pump hasn't been fitted. He informed me that he did this as he didn't want to cause pressure issues on my existing combI. 28I junior. I sort of understand this and wasnt worried. But having had another look I have noticed he hasn't fitted the mixer value which I assume is a big issue.

Any advice on how to proceed? I don't want to damage the boiler but I also don't want to be over heating my floor and damaging screed and tiles.

Many thanks in advance

The wiring centre/system. You need to get them back in.

pump should be wired to the two port valve /boiler stat/under floor controls etc

and post a pic up of whats changed if you could

So we are now in March. After much talking the pump has been connected to a power supply. But there is no surprise that this has been done incorrectly. It has been wired to a switched spur and is either on or off. No wonder he said having the pump running would affect the boiler.

I have now told the builder that this 'Plumber' is no longer allowed in my house. Problem is builder doesnt have another he can call on. Anyone in SE13 fancy having a look a what he has done and offering some advise?

Sorry your having problems still, as Shaun said previously you need the controls sorted out for the ufh now. Maybe try the find a plumber section on this website.

You need a wiring centre like in pic that will have everything yo need
or a 2 port valve and a decent spark to wire it in to heating
