I wanted a Worcester CDI 37 boiler but when the plumber came he said this model is crap and said the Viessman vitoden 100 is really good and cheaper. what do you think?
Personally I rate them as similar with WB having the slight edge on the grounds of manufacturer support.
Not that I would specify either as a first choice.

+1Ideal make their own heat Exchangers as well - says nowt .
But as it happens - Intergas make their own heat exchangers too.
You can certainly buy better than Viessmann.
Keeps telling me to fit their light commercial range - pretty sure I am not allowed to fit anything sold as a commercial appliance on my registration
