We have very hard water in Rotherham. The boiler has been serviced annually but we did have a problem with leaks which were fixed under warranty. The system currently does not contain any inhibitors as it was refilled after a leaky radiator valve was fixed about 18 months ago.
Just had the engineer round to service my Ferroli combi boiler. The heat exchanger was very badly damaged and the boiler has now been isolated.
Worth repairing with a new heat exchanger unit or replace with new boiler?
Not sure what caused the damage, any ideas?
The boiler is 4 years...
