Very Noisy Central Heating

[hans_stiles]

Our central heating is very noisy when it comes on. It sounds like someone is using an orbital sander or something in a room downstairs.

The radiators all work - in fact the noise got worse on Wednesday night, and at the same time, two radiators that weren;t working very well suddenly sprang into life.

I've looked at some of the other posts and have ordered a couple of bottles of cleaning fluid and a bottle of inhibitor from screwfix direct.

My worry is that there a faulty part too. We get the system looked at a couple of times a year and the last time the ch specialist said it needed a cleanout but that it was a relatively simple job and so he didn;t we should need to pay him £xx per hour to do it.

Does this sound like a kettling problem?

Hans,

Just joined the forum and come across your post, mine has the same problem. My system is an Ariston SX20MMFICE, and like yours only makes the noise when water is drawn or it is heating the GCH system. Some of the guys (and girls) who post replies need as much info as you can give (for future reference). If I sort mine, I'll let you know.
