We had a Viessmann Vitodens 100 boiler installed by a very good Viessmann registered installer 5 years ago, the boiler has never run through a winter since installing without a problem, I have had 2 expansion Vessels, 2 PC boards, 1 Spark Generator, also came home one day to find the boilers inlet cold water feed had broken thus flooding the kitchen, I have had numerous other problems including the air flap sticking, more error codes than Microsoft. Do not buy one of these boilers, they are nothing but trouble. if it was not for the fact the installer is a very good friend of mine, I would not have put up with it for so long, also has of this moment 4th Jan 2011 I have no hot water or heating since new years day, F4 error, another spark generator I assume. DON'T BUY ONE, TOTAL RUBBISH.
