I had my new Viessmann fitted just over 12 months ago and I am so glad we chose your boiler I have been really impressed with the system everything looks like its made to last, its economic good looking much better than my last system which began with a w which I nearly had updated but after reading pros and cons I chose you. Fitters also did an excellent job.
