Noisy heating pump

[Hogweed]

Hi folks, and thanks for providing this facility

I moved into a new Redrow house a year or so ago, and generally it's fine, except that, every time the heating comes on in the morning, the motor wakes me up with its loud rumbling. Redrow sent their plumber round, and he discovered it was leaking, and replaced it – but the new one’s the same. I’ve spoken to my neighbours and it seems they’re all the same.

The motor is an Altech SG6, if that helps. One of the problems is that the airing cupboard is directly above the main bedroom – but anybody sleeping in the second bedroom (which is beside the airing cupboard) has the same problem.

Surely these motors should be almost silent, or am I deluding myself? I mean, this is the 8th house I've lived in in my life, and I've never had the problem before!

I don’t know what kind of system I’ve got, but there’s a (condenser?) boiler downstairs in the kitchen, and a big hot water tank in the airing cupboard, so it's not a combi, if that helps…

The plumber said it was normal

Thanks
Roger

pump should be near to silent usually its cause by a lack of fixings on the pipe work try holding the pump still while its running to see f it makes any difference if yes then id get on to redrows

Thanks - yes, it's just in the middle of a big long pipe! That's probably it.

True Steve, most of these new houses use that flimsy metal stud partion now which IMO is a ,load of crap, Iam sure the manufactures will disagree with me though. This is then clad in plasterboard, so wtf are you supposed to get a decent fixing into? a heavy pump will pull those spiral fixings out when you try and tighten up the unions. Iam sure that the walls flimsy construction will add to the resonation (does that word exist?) of the pump. At least with stud timber you could screw some wooden batterns across the back of the cylinder cuboard to screw your pipe clips to. Have any of you ever tried screwing somthing into those metal studs? ball ache.

I’ll have to look again, but I don't think the pump is attached to the nasty stud wall at all – I think it's just sort of spliced into the pipe which runs from out of the floor of the airing cupboard and up somewhere… maybe I’ll take a pic and post it?

If it doesn’t, it should!

Yeah... not exactly supported, is it... just sort of hanging there!

ahhh, tobe fair hes managed to get a baton across the back for his pipe clips!, when I was on about spiral clips I meant to support the piewrok that the pump is on, your install looks quite neat and tidy to be honest, maybe he could have put another wooden batton and clip below the pump, try this but I bet Ive just got this feeling that it wont improve things,btw sorry to call the walls of your new home flimsy and nasty.

Just a possibility, but is the noise coming from the pump or is it more of a vibrating noise? I ask this because it's possible there may be air in the system and that will make it noisy. It probably isn't the case as you say your neighbours have the same problem, but could be worth checking out.

I changed a pump some time back in a house and it was a nasty bugger to replace. The ball valves wouldn't close properly and it was so tight and cramped it took me ages to get the rubber washer on and the pump in place. All the while the water was leaking from the system. When I went to replace the water the pressure was real low as the header tank was too low and it took an age to refill. Due to air in the system you could hear the pump a lot noisier than normal, and it was only when I got all the air out that it returned to normal.

Why not – it's the truth! Same as the nasty dab’n’slap plastering for the walls. Unfortunately it’s the way houses are built nowadays, but I didn’t know any of this when buying it…

Yeah… I know. When the water has got low in he past the noise gets MUCH worse – but since the house settle down from new, the pressure stays around 1 now.

I don't know if the pump should be bled though?

Bleed the pump, it only takes a minute. Just open the screw on the front most of the way and let any air out. If there is air you will see air bubbles. Just wait till it's running clear. Mind though, it gets very hot! Also, put a rag/towel underneath to soak the water - there won't be much water as your only opening it for less than a minute.

What, is that the really big screw front centre?

Haven’t had a chance to touch it yet – probably be the weekend before I get the chance, I'm so busy. It DOES seem to get quieter as it runs on after starting up – I suppose it could be air, or it could be something to do with heat expansion…
