Title: central heating cleaner
Post by starflip on Oct 7^th, 2010, 8:11am

Could somebody explain to me how i get central heating cleaner into my system, it is a completley closed system with a pressure vessel built into the tank.

Most of my rads are sludged up im guessing as they dont really warm up, I have the bottle of cleaning solution, but just dont know how i get it in the system....?

Explain please.

Some info on the boiler make/model etc may help.

Just draining it out and flushing it with fresh water if it isn't too bad.
