How do I descale the heat exchanger on my gas fired central heating

system.

If it's badly scaled up, you need a descaling pump and the appropriate
chemical (see the Fernox or Kamco websites)

As it happens ... I have a descaling pump, I'm in Watford


Maxie, how much do these cost to buy?


I would have thought you would have known such things.


Maxie, I don't buy one every week.

I have no idea
what mine cost, but they're not cheap.

For anyone interested

http://www.kamco.co.uk/descaling.htm

might be a useful site to look at


Thanks Maxie.
