Vibrating pipes when heating is on.

Jimmy_Neutron

When I have my heating there is loud vibration from the pipes which go to the upstairs radiator. Anyone have an idea what could be causing this vibration?

Thanks

Pump bearings?

Air in the system ? Bleeding all of the rads is a piece of cake, will take you 15 minutes and cost nowt ( or maybe 50p if you have to buy a bleed key http://www.wilko.com/plumbing-supplies-and-accessories/wilko-radiator-key-easy-grip/invt/0343482

But do bleed the radiators without the system running!

Any reason for this? I always bleed when system is running in full power.

Wookey

What type of heating system is this? Open fire, oil, renewable or gas. If it's open fire or renewable you could be producing to much heat/hot water (heat leak radiator), if its gas or oil then the most likely cause is poorly clipped pipework somewhere or piping that is rubbing against timber when expanding/contracting due to heating up or cooling down, this is more likely to be a creaking sound rather than a vibration. If the rad upstairs is turned of does the sound occur? Check all visible pipework for movement/vibration to narrow down the area/source.

Assuming it is a pumped or pressure system or both do you want water being forced out at pressure. Alternatively do you want air being sucked in. I am prepared to be proven wrong but I have always assumed that it is better to bleed when all the air has found its way to the highest point in the system.

Possibly water hammer. When it's happening, if you've got a trv on the rad then turn it up or down and the hammer may disappear. If not, then turn the valve on the rad with the non-smooth cover either way and the same may occur.

No no no no no no!!!

There's a risk of sucking in air as water in the rads cool. Always bleed rads when the central heating system has fully cooled down. Start with downstairs then upstairs rads as slowly any remaining air moves to the high points.

I will try all your suggestions today when I finish work. The heating is from a combi boiler.
