With the Vitopend 200-W, Viessmann offers a wall mounted gas fired boiler with a particularly advantageous price/performance ratio, excellent heating and operating convenience, compact dimensions and a timeless, elegant design. The Vitopend 200-W is one of the most affordable in its class, not only in the purchase price, but also where running costs are concerned. After all, it can achieve a high standard efficiency of up to 85 % (Hs) / 94 % (Hi). The premix burner of the wall mounted gas fired Vitopend 200-W boiler is particularly economical because it adapts its modulating burner operation to the actual heat demand. Automatic flue gas adaptation ensures that combustion meets the actual conditions, for example when there is a change in weather conditions. Not only is it easy on the pocket, but it is also environmentally friendly. Consequently, the Vitopend 200-W emissions are below the requirements for the «Blue Angel» certificate of environmentally excellence. The compact Vitopend 200-W fits practically anywhere, in the kitchen, the bathroom, the attic, in recesses and corners — because clearances to the side for service work are not required. The Vitopend 200-W can be quickly fitted by your heating contractor and is operational in no time, be it in a new building or replacing an old boiler.

Low temperature gas fired boiler Vitogas 200

The Vitogas 200-F up to 60 kW is the smallest model in the freestanding gas fired boiler range from Viessmann. It is highlighted by its high performance, operational reliability and long service life. Both its price and dimensions make it an attractive choice: It fits most budgets and into almost any space. The Vitogas 200-F is not only miserly in its space requirements, but also where outlay and energy consumption are concerned. Its stainless steel premix burner lets it perform better than required for the «Blue Angel» certificate of environmental excellence and the Swiss Clean Air Act. The heating surfaces of Vitogas are made from proven special cast iron and the dimensions have been designed to provide the lowest possible stress on the heating surfaces, so you can enjoy your new gas fired boiler for longer. And you can enjoy higher operational reliability.

Low temperature gas fired boiler Vitogas 200

The Vitogas 200-F always does well — with a rated output of 72 to 144 kW or as a multi-boiler system up to 432 kW. The standard components of the powerful gas fired cascade are the proven Vitogas 200-F (up to 144 kW), the matching flue gas header and the Vitotronic control unit. This makes the Vitogas 200-F an ideal solution even in larger buildings, where quiet operation and an optimum price/performance ratio are a must. Of course, the «large» Vitogas 200-F also offers the whole range of leading technology from Viessmann. These include heating surfaces made from special cast iron, the atmospheric premix burner and the Vitotronic digital control units for operation with modulating boiler water temperature. The Vitogas 200-F ensures high operational reliability, low emissions and low energy consumption. A huge plus as far as the environment and your wallet are concerned. The stainless steel atmospheric premix burner not only ensures excellent emission values, but also minimum noise levels during its operation and on starting. This is easily explained: The special feature of this burner is its segmentation into several gas fittings. This ensures rapid, even gas distribution and reduces the start-up noise development to a minimum. Even in partial load operation the entire burner area is fired up, ensuring a balanced loading of the burner and the heating surfaces that is kinder on the materials used. The Vitogas 200-F can also be used in the output range 72 to 144 kW with a matching flue gas header; also in dual and triple-boiler systems in cascade operation up to 432 kW.
