    Is UFH flow and return reversed?

    Thanks Rob, I did as you suggested. It seems that perhaps the motorised valve is faulty (or not wired correctly), as the return from the blue valve gets much hotter than the flow to the red. The motorised valve does not seem to actuate (the lever remains loose). The pump comes on straight...

    Is UFH flow and return reversed?

    Hi Guys, I wonder if somebody could give me some advice, please? I've had an extension built, and as part of the project, I had the boiler moved and a single loop underfloor heating fitted to the new extension ground floor. It seems to me that the UFH flow and return is mixed up. From the...

    Extension electrics

    Just a bit of an update. I went to connect two new wall lights to the new circuit that the builder put in. They are in the original bedroom, so don't form part of the extension. Before I connected them, I isolated the "upstairs lights" and checked for a live wire. My meter told me that it...

    Extension electrics

    Hi guys, I wonder if anybody could give me some advice, please? I am a homeowner, and I have just had a two storey extension done. My builder was recommended by my architect, and the work has gone through building control. I have an issue with the electrics. To cut a long story short, the...

    Central heating Flow and Returns seem to be mixed up

    Hi all, Thank you for all of your help. I've tried to do as many f your suggestions as I can. I can't take a useful picture of the loop pipe as it joins the system under the only par of the downstairs that is still carpeted, and all our furniture is in that room. However, today I checked the...

    Central heating Flow and Returns seem to be mixed up

    BTW I know that there is a lot of air in the system, I can hear it at the pump, but none of the radiators have air in them.

    Central heating Flow and Returns seem to be mixed up

    Correct on both counts. One of the radiators is starting to heat up, but not very quickly. The other is stone cold. While the system was drained down yesterday, the builder came in and blanked off a pipe that was looped together. That was for a radiator that has been removed and not to be...

    Central heating Flow and Returns seem to be mixed up

    Hi, The rads did work before, but never seemed to get as hot as upstairs. He only recommissioned the boiler ( I think that was all the builder paid him to do, and it was getting late when he finished 18:30). The F&E tank has water, and there are no other valves up there. He didn't go anywhere...

    Central heating Flow and Returns seem to be mixed up

    Fair enough. I have phoned, but no reply, so I have sent him a message. I just wondered if there was anything I can try in the meantime.

    Central heating Flow and Returns seem to be mixed up

    Hi guys, I am having an extension added to my 1930's house. The builder has installed pipework for radiators and towel rails, upstairs and downstairs. Yesterday a heating engineer Gas Safe), came to move my boiler. I don't have any concerns about his work. However, I can get heating...
