Boiler no power, it's 2 years old, called customer service yesterday very nice helpful & friendly, arranged engineer to call today, engineer called today and immediately knew what to do, replaced fan, boiler fixed, a fabulous service peace of mind warranty, just excellent all round, can't recommend enough, my sister is changing hers soon and she will be buying a Viessmann. What a great service, thank you.
