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.
