When installing the "New Vaillant Ecotec Plus Combination Boiler" I have had some issues with the new insulation on the back of the boiler. I will show you what I have done to over come the problem.
Also when replacing an old Vaillant ecotec with the New Vaillant ecotec Boiler everything should line up but I found that was not quite the case. I will show you what I did find.
PLUS I found a really useful Menu which is sort of hidden.
