Thanks for your advise everyone. Waterworks, you were spot on. Moved the left hand pipe to the third from the left outlet (I could not get the other two on the left to undo without possibly snaping something). Worked great. Thanks again

Sorry for seeming a bit thick, but just to make it clear are you saying - Looking at my photo move the left hand pipe (out of the two in the top right of the photo) and move it along the same side on the manifold but to the left hand end in the photo? Don't forget there is six outlets under...

Ok thanks I will give that a try. Did I mention that out of the two pipes I connected (Top right in photo) it is the left hand pipe that is getting hot.

Just double checked. The pipes from the radiators that the manfold feeds are coming and going from this Manifold, on looking closer some auctually come out and go back in the same side of the Manifold.

Hi, I'm not being funny, but what difference would that make? All six outlets on that side of the Manifold were blank, I just connected it into the first two.

Thanks for the quick reply. I do have another Manifold but this is servicing other radiators. I'm sure that this Manifold has the radiators branching off it and returning to it, I can see the pipes. So do you think the problem is I have the flow and return on the same side and the Manifold is...

Hi, My central heating is is feed from a 22mm loop that has 10mm manifolds that branch off to the radiators. I had a heated towel rail that had an electric element in it. I have taken the element out and connected the towel rail to the manifold. Does it matter where the flow and return from...

So should I wrap the pipe first with the plastic duck tape then put it in the hair felt lagging sleeve? O rput lagging on then wrap the lagging?

Thanks for the reply. Is felt push on the tubular roll kind, Is there only on sort of this kind, so I can;t make a mistake? I should cover the pipe with duct tape first? Will the duct tape stay on ok once it heats up? I ask because I want to run the heating for a couple of weeks before I...

Hi I need to put some radiator pipes in concrete screed. I have been told to use Hair felt lagging of the tubular sleeve kind to cover them in. Is it right that there is a special kind of hair felt lagging that has a plastic sleeve inside which is used especially for concrete screed or is it...

I'm having problems finding anything from a search of this site. Either I'm searhing wrong or there is nothing.

Hi, I may have to run a new set of downstairs pipes for my central heating and they will be in a concrete floor. It looks like I have a leak under the concrete somewhere that I can not see so I think I may start with a new set of pipes. What is the pratice for laying copper pipes in concrete...

Thank you everybody for your advice. As to the Power flushing, no I did not have it power flushed before the Boiler was fitted. I do know that it says I should have had this done but before the new Boiler was fitted I had taken every Radiator off as I was putting the TRVs on and flushed it out...

Just giving you an update. Checked Tank level this morning and the tank had lost about 15 gallons. Filled it up again and run upstairs zone again this mornig for half hour. Water level went up a little then 3/4 hour after switching heating off the level has settled back to before I turned...

I have done as you advised and at first test the upstairs zone was run for 45 minutes and I never seemed to lose any water from the tank. I run the downstairs zone for 45 minutes and there has been a drop in the water level in the tank. I see no leaks anywhere downstairs. I will do this test...

Thank you for your reply, I will try what you have said. I'm not sure what you mean by one or two inches above the feed to the C/H system. Do you mean one or two inches above the outlet pipe on the F&E tank, so the f&E Tank should be near empty? By the way my F & E Tank is raised up about...

I have a worchester greenstar oil condensing utility boiler fitted 25/32 . I have 24 Rads on it, 11 downstairs 13 upstairs. (Sounds like a lot of rads but I will only have half of them on at any time, My Cylinder is approx 1100mm high.I also have a Groundfoss Pump and 3 zone valves by the...

Thanks for the replys. The thing about the flow and return pipes is that the TRVs were on the correct ends before I had the pipework changed for the new boiler. Is it possible for the flow and return pipes to be connected to the boiler wrong? Why should the original return pipes get hot...
