Hi all. Hope you have all been keeping well.
A while back I decided I only wanted to fit one brand of boiler and decided on Viessmann due to space for servicing and changing parts if ever needing to. I am finding my decision rather hard due to the different clearances on flue runs and cupboards to other boilers. Now I want to replace a 16yr old ecotec pro with a flat roof terminal which is adjacent to a window. Vailliant require 600mm which the current one is. Viessmann require 1000mm. Now I would need to run a flue externally up past the window and above the roof with a different terminal. Viessmann have an external flue kit which is 3 fittings and costs over £200! Anyone fitted one and know what this kit does? Any way, it makes it extremely expensive.
Now looking around, Atag give you 600mm and Baxi give 300mm clearance. What's the crack?
