New boiler and UV cylinder quotes

[Trevor C]

Had three quotes for a new boiler and UV cylinder. All quotes are very similar in price (only about £200 difference between the most expensive and the cheapest). They are all accredited installers meaning we should get the maximum guarantee. So it will probably come down to which is the preferred brands:

Quote 1 = Worcester Bosch Greenstar 18i + Albion Ultrasteel Indirect 210

Quote 2 = Vaillant Ecotec Plus 615 + Joule Slimline Indirect 205

Quote 3 = Viessman 100W 19kw + Cornerstone Indirect 210

All three quotes include a power-flush prior to installation.

All three brands seem to have a good reputation and came out well on the latest Which reviews. My main requirement is reliability - having had regular break-downs with the previous boiler. Any views from the professional on which of these set-ups are likely to be most reliable?

Thanks

I'm not gas but I'd like to be! Viessmann are the best IMO from what I've gleaned and read.

Vaillant and Joule would be my choice
Make sure you get a magnetic filter

I like a cylinder that has internal expansion (none of the above)
