Help!!!!

I drained 4 out of 5 radiators today and then inserted central heating system cleanser into the expansion tank in the loft.

Now the radiaotors are cold and the pipes near the boiler are making a constant rattling noise. I think i have air in the system somewhere.

On thinking back the feed tank barely emptied.

I need some advice.

sounds like you have a blockage. useally where the feed pipe from the tank joins the system.
the boiler will rattle with no water in the system and the pump could end up seizing.

is it easily solved or will i need a plumber to come out and charge loads of money?
