I posted in December but no-one could answer my query. I have a pump plan set on speed 1 for HW and 2 for CH. The CH pump makes a very strange noise - a sort of quiet howling? When the HW pump is running too the noise is not too bad but it is very noticeable on CH only. I tried setting...

Not sure I know what Nige F is on about!/ The towel rail is on the CH circuit. I do have another one on the HW circuit. I dont think that there is any pumping over - that is why I had to have things changed because I was getting water coming out of the overflow. I have felt both the...

Had pump plan fitted so now got pumped CH and DHW. Pump is quite noisy (its on 2 for CH - was 3 to start with) but also when it comes on for CH there is a sound of rushing water through the pipes surrounding it and then gurgling in the bathroom towel rail. The top rail fills with air over...

Having spent a lot of time worrying, asking questions, having a new cylinder and now changing the pipework and having new pumps fitted I think that I have just realised what my original problem was. I had gravity HW and pumped CH. Every now and again when the CH clicked off there would be an...

I have had a lot of problems with severe pumping over and so have had my system changed from gravity fed HW and pumped heating to both of them being pumped using the above. This is now situated in the airing cupboard rather than by the boiler - not sure why. The HW pump is on 1 and the...

Gosh, I dont want the heating on - might it just mean only the bedroom radiator would be on when hot water is called for - if it is pumped that way? I will do what you suggest first.

Thought my problems were solved - but we had an almighty bang last night and water came out of the overflow. Plumber suggested converting to fully pumped as suggested on this forum too. Problem is boiler cannot be near the cylinder. Cylinder is in a cupboard in a corner of the bathroom...

AL It is very interesting 'listening' to your thoughts. My plumber - whi is an ex BG engineer - is coming on Friday as he has to flush the system through in any case. We will remove the boxing around the boiler pipework and I can take some pictures. The lack of an injector disc...

Oh, and I am certain that the boiler does switch off.

Thanks. I havent seen a cylinder thermostat because there is no electricity in the cylinder cupboard but I am sure that the hot water doesnt get as hot as the radiators. Will this motorised valve be by the boiler? I wouldnt be at all surprised if the boiler is fitted incorrectly but the...

One last thing. We can only have CH if we have HW so I think that this might mean we don thave these motorised valves. Re the pipes going into and out of the radiators the wrong way - could this also mean that the pipes are going into and out of the boiler the wrong way - although they go...

Okay I thought that gravity was the opposite of fully pumped. It is a 1950s house which is probably on its third boiler. I'll take a picture of the pipework and the pump. I dont think that my plumber has a clue - hence I will probably need to engage someone else.

Thanks all. Softus - having read other threads have got the impression you can be a little 'abrasive'! I am a woman actually!!! Yes - we have a gravity system. I dont KNOW if we have had the problem since the new boiler was fitted but think that we probably have. I was only...

I will have a look when I get home. Are you saying that this is either a blockage or a faulty valve (if we have such things)? Where is the blockage most likely to be? Having read lots of threads I thought that it was in the cold feed pipe - if I knew which this was. We have just had a new...

I have a gravity fed system with a potterton 60e profile which replaced a baxi about 4 years ago. The pump used to be inside the boiler now it is next to it as all the pipework wouldnt fit in it. It was an emergency replacement as the old boiler packed up. I think that since the new boiler...
