Viessmann Vitodens 100-W

Works as promised – After over 20 years service our boiler for the hydronic heating ceased working. Our hydronic technician recommended the Viessmann gas boiler made in Germany. We went with that and it was installed and turned on a week ago. It is working perfectly just as our technician said it would. Completely automatic and keeps the house temperatures stable at the settings at all times. Could not be happier so far. We will have to wait until next winter to see how efficient the unit is but we were assured it will be much cheaper to run. The only down side was that the new whiz bang thermostat was not available when the unit was installed. But the National Sales Manager promised to “look after us”. I will hold him to it. All in all a good experience from start to finish. www.viessmann.com.au Vitodens 100 mw condensing boiler Update. After the first couple of weeks the unit is working perfectly and is SUPER efficient and uses very small amounts of gas. Very pleased.
