Hi,
I would like to thank all of you for your help in the renewal of my heating system, I read a lot of the archives and posted a lot of questions and you were all very helpful.
The boiler is a Vaillant ecoTEC+ 937(Storage combi boiler) I initially was going for unvented hot water but no unvented cylinder would fit in the space I had, this boiler gives fantastic hot water. After much research on this group I went for the Honeywell CM927.
I expected a boiler of such a big size to be noisy, but it is very quiet.
If you really want to see pictures just ask and I will post the link.
Thank You.
