Christ it's only a boiler. All the top brands are pretty good and installation matters more anyway.
Pick one, get it installed properly by a man that can speak properly; do something more interesting.
That is the problem with a lot of trades yes to them it is simple and not worth the hassle when you have a customer who wants to know the ins and outs of everything, but to him at that point it is the most important decission he has to make at that time and for many a substantial capital investment that they do not want to get wrong ?
When I was running the bilding firm I started to see a 100k job as small and a pain in the backside I think somewhere along the line we tend to forget that people are all different some needing more hand holding than others !
