Hi there,
I have just had a new boiler installed (thanks again for lots of invaluable help over that)
Everything seems fine except that it is producing quite a large ammount of Hydrogen (I tested the vent gas as suggested on another post)
The system was flushed by a plumber (I happened to notice that he was using Fernox products if that makes any difference) and then Sentinel X.100 inhibbitor was added. Existing rads are at a guess 20 years old. 1 new rad was added at the same time as the boiler. All copper pipes used (i.e. no plastic ones). The system was converted from an open vented to a closed system at the same time. (I didn't have any Hydrogen problems with the old setup).
The gas seems particularly bad in the towel rail (maybe a third of the towel rail every day) but is pretty bad in all the higher rads. The water which comes out of the rads has visible brown particulates in basically clear water. I tried to test it's acidity with a pond tester (Could not see any colour at all!). A very basic 'school boy' test bit bicarb did not show any fizzing either.
It is only a week since all this was done. Is this normal? Fresh steel exposed during the flush which is 'bedding in'? Should I be worried?
One last thing (in case it is relevent). The system is filled with water which comes through an ion exchange water softener.
