The boiler initially seemed to be efficient and was reasonably priced. My heating bills have gone down. My main reservation is the after sales support - my installer took several days to come out when the boiler stopped working during cold weather. I had better service with my previous boiler from another company so I am still anxious that the warranty won't get me urgent help f I need it.
