I've got a vaillant vcwgb242eh combi boiler. the DHW heat exchanger is leaking. Is this an easy fix?
How much could I being looking at being charged to get someone to do it for me? I know a new DHW heat exchanger is around £80...
I've got a Vaillant VCW GB 242 EH or VCW GB 282 EH (not sure of the difference).
The problem is I seem to have a leak on the DHW heat exchanger... Is this exspensive to replace?? Would parts still be available?? :cry:
