I have a Vaillant 831792 GB boiler that has given excellent service for 18 years but I feel that it's probably due for replacement for something more efficient.
I would appreciate comments on models to shortlist when comparing quotes.
Are models available (newer Vaillants?) that would use my existing pipe layout as this would (I guess) simplify installation and minimise disruption?
Thanks.
