In October’s Which? survey, owners gave Viessmann five star reviews for reliability and brand satisfaction (and likelihood to recommend to a friend). Heating engineers also rated the brand highly. Non-incentivised engineers reported they were likely to recommend a Viessmann boiler – one of only three brands to achieve this in the survey.
