My boiler was installed by Alpha Gas Ltd who did an amazing job. Im glad that they recommended the Viessman boiler as other companies had not. I have had no real problems with the system, other than when the battery ran in my room stat. So efficient, house has never been so warm. Lovely hot water. Would recommend to anyone looking for a new central heating system to check out Viessmann boilers. We love the ability to turn the heating on or off from anywhere via the wifi app. Highly recommend.
