Wall mounted gas fired Vitodens 200-W Wall mounted gas fired Vitodens 200-W Wall mounted gas fired Vitodens 200W


Vitodens 200-W boiler is a wall powered by gaseous fuel, elegant and compact design that can provide the ideal price / performance and is comfortable for heating and hot water.
Is part of the range boiler Viessmann wall solutions which are good for apartment buildings, firms, institutions or vile. Can be cascaded up to four boilers and power up to 420 kW. Standard efficiency up to 109%  . Vitodens 200-W wall boiler consumes less energy because the additional use of exhaust heat.The result is a standardized energy efficiency up to 109% contributing substantially reduce heating costs and reduce pollution.                                                                                                                                   
Effective duration
Vitodens 200-W is equipped with a heat transfer surface Inox-Radial, which offers reliability and durability needed, guaranteeing a high energy efficiency.
Modulation range extended
This device has a cylindrical burner revolutionary Matrix, a Viessmann innovation, which has a capacity of modulation in the 1:4 expanded.
Another novelty lies in the integration of Lambda Pro Control function that allows automatic adjustment of combustion parameters according to different types of gas used.
Comfort in hot water
Combi boiler Vitodens 200-W wall is provided with function to maintain hot water temperature adjusted.
By this, the beneficiary is immediately available hot water temperature.
Assembly cascade
Vitotronic 300-K cascade allows linking up to 4 boilers Vitodens wall in one set of heating.
In this situation the power boiler automatically adjusts the heat and can thus be in operation only one or all four boilers.

Advantages in use
Wall mounted gas fired condensing gas-fired power:
Heating from 4.8 to 105 kW
Combi from 6.5 to 35kw
Possibility of cascading up to 4 boilers Vitodens 200-W wall with total power up to 420kW.
Standard efficiency up to 109%.
Heat transfer surfaces of the stainless steel Inox-Radial:
self-cleaning effect of smooth stainless steel surfaces
Corrosion resistant stainless steel alloy advanced high quality.
Matrix cylindrical burner:
Long life due to the structure of stainless steel wire, low emissions of pollutants, optimum compatibility between the burner and heat exchanger, comfort in the hot water temperature maintenance function,
Intelligent combustion control by Lambda Pro Control function does not require replacement of nozzles passing another type of gas, running at optimal parameters even if fluctuations in gas quality, pollutant emissions remained constant at a very low, quiet combustion due to low fan speed.
