Long time no post! Happy new year to all!
About 2 years ago I had an inset backboiler stove (Ború Chieftain) fitted in with the existing OFCH.
Each heating loop was fitted with a non-return valve.
Within 1 week the first valve failed - as in stuck open. To date 2 more have also stuck open.
I was told by a builder that this is a problem with wood/coal fired back boilers and the secret may be to add a chemical (scale remover/disolver or the like). AFIK when the system was comissioned no additives were added.
Any suggestions?
I know there are several additives (Fernox make a lot) for the heating loop but which would be best.
Trouble is that plumbing supply shops that I visit aren't run by plumbers any more!
