After the central heating has been turned on and the boiler has ignited there is a whooshing sound followed by constant banging and clanking coming from pipes close to the boiler. There are also noises which sound similar to switches or valves turning on and off. I immediately turn the heating off as it sounds as if it is about to bring the house down, and the banging stops after about 20 seconds or so. Does anybody know what is going on?

Sounds ok to me. It's probably just the pipes heating through. I don't get this as I have the new push-fit plastic stuff, by my parents heating system makes a variety of different noises, including the pipes banging together as they heat up.

I don't think it's the pipes heating up as the boiler turns itself off after about 30 seconds of constant banging and clanking, so doesn't have chance to heat the pipes up. I've never had this problem before and have been in the current house for 4 years.
The boiler is old and is a Wickes 45F manufactured by Halstead.

It didn't say that the boiler shut down in the first post!
No offence taken as that is obviously not what is happening here. A faulty pump is a much better place to start with this one!
Thanks Gas2air. I thought it might be the pump as it is pretty old. I don't suppose you know how much it would cost to have a new one fitted? I've seen new ones for about £50-£60, but then of course there's labour costs.
£60 for a 15/60 Grundfoss, depending on your system. Labour well a pump can be changed in 15 mins, if the valves shut off, 30-45 if not. Estimate!!
It may just be stuck if your on a gravity HW system however, what pump is installed currently?

No probs. Yeah, roll on the weekend
Hi
The symptoms you describe are typical of a failed pump. Could be freed, could need replacing but judging by its age, I'd say replace anyway.
Please don't take any notice of alanperu, he clearly has no idea and thinks that 'bringing the house down' is the norm
You haven't mentioned what type of boiler you have so its only an assumption on my part....but a pretty safe bet

Yes, I agree. Ignore everything I have said here (except this)!
