Combi Closed System - Cleaning?

Spleurker · 21 Nov 2004

As it's a good idea to flush out CH systems and put additives such as Fernox in, is it possible to do it with closed systems used with some combi boilers?

yes, fernox do a special product which looks like a tube of silicone. It fits in your mastic gun so that it can be pumped into a sealed system. With the standard product it is introducted via a radiator bleed valve.

Or... if you are a tight arse cowboy like meself, you can get a 1/2 bsp male/female elbow screw it into rad and pour it in...
