Gas Central Heating

Hi all,

A strange question and one that I think has an obvious answer.

Over the last couple of days we've noticed our radiators seem quite loud. It sounds as if you can hear the water running through, and it only seems to be the downstairs ones that are so loud, the upstairs seem fine. The boiler is a combi and is downstairs, and the loudest seems to be the hallway which is the closest radiator to the boiler.

We've been in this house for a couple of years now and I suspect they have always made this noise and been this loud, but now we have a little one we're being quieter on a night in the living room which makes the radiators sound louder. But thought I'd double check.

The radiators don't appear to need bleeding as they are hot from top to bottom with the exception of 1 that looks like it needs replacing (no air comes out at all when you bleed it but the heat only gets halfway.) and the pressure on the boiler is in the range for the boiler when the heating is on.

Normal I'm sure but thought I'd check. They are old radiators in a 1930's house. Not sure how old but they've not been repalced in a good length of time because they work well!

Cheers.

Sounds like one of your rads is full of sludge.
