Viessmann Vitodens 200-W Boiler Overview

This boiler was installed 6 years ago and has never functioned correctly. Every few days we have no hot water in the morning and I have to go to the basement and re-start it. Now every morning I go down to the basement as soon as I wake up to make sure that it is running and does not have to be re-activated. In the winter, if the temperature is below freezing, we cannot get the house above 50 degrees. I called the regional representative and he was not helpful at all. The alleged service person has added pumps to the system, but nothing works. Stay away from Viessman.

I have sold viesmann boilers for many years and they have always been top of the line which are also more expensive than other boiler manufacturers. To my surprise they have produced poor quality for their electronics. Last year I had a main controller go on the vitodens 200 first thing the tech asked is there moisture on the gas valve or on the controller. There has been no signs of moisture so he states must be a power surge. Nothing else in the home failed by a power surge. The fix was to put a new circuit board in and coding plug this is when I learn there is only two year warranty on boiler parts which is 2 years 6 months old. So I am the person to give the bad news to home owner of the huge cost to repair. Now a year later I just had another client who has identical boiler and approximately same age ( now it is 3year 6 month old) once again tech at viesmann says is there any moisture on gas valve or circuit board and I say no there is nothing. Says it must be power surge and once again nothing else in home is effected Tech then states it's an easy fix you need a new board. Easy fix ! I know now the cost and again I have to inform my client the news. With two units doing the identical problem this is not a one off problem. I have written to sales rep to discuss my dissatisfaction with their product. No reply. Shame on viesmann for putting on the market an inferior product which we have paid too much for. Don't be fooled by Viesmann's idea of now offering 5 year warranty on their boilers now. They dragged their feet for two years. They are one of the last manufactures to offer this. Other boiler manufacturers has offered 5 years on parts for two years now. I hope more people voice their concerns about the vitodens so maybe viesmann starts to stand behind their product. Looking forward to the trade show in March to speak directly to the Viesmann Brass.

Wish I would have read some of the reviews. Less than a year and need to replace flame sensor and igniter which is apparently not unusual and will only cost $1540.00. Repair tech needs your manual so they can read how to repair the unit. Suppliers talk about how Viessman is the best, the other brands could not be worse. Spend $6000.00 to buy and then $1500.00- $2000.00 per year and they call it efficient!!!

I am a contractor for Viessmann out of London Ontario. I can without a doubt say that Viessmann is by far the worst brand of boiler going. When they break they are the most expensive and the hardest to troubleshoot costing the customer a fortune not only to replace the failed parts but to diagnose the problem. I am currently on site and have been waiting for a return call from tech support for over 2 hours now. The customer will be billed $89.00 an hour for the delayed call back as always.

Main control board failed in a residential clean environment after only 3 years and Viessmann would not stand behind it. Granted the warranty at the time of install (2013) was only 2 years but new ones (2016) are now 5 years. If this was really a top product then the manufacturer would stand behind it when an occasional failure happens to maintain its reputation and customer satisfaction. Take my $1600 lesson into consideration when making your choice.
