Our old baxi boiler has broken down and can no longer be repaired, we have had a gas engineer out to quote us on a new boiler. I know nothing about boilers and just want a good one to supply us with Heating and hot water, I don't need anything fancy. These are the 3 boilers he quoted us: Vaillant ecofit pure 418, Worcester bosch 18ri and baxi ecoblue advanced 19kw. Any reviews/options on these please? I've struggled to find reviews. Thanks
