Commercial Gas Boilers

The Vitodens 200-W high output gas condensing boiler is one of the most efficient and reliable boilers for commercial use.
The Vitodens 200-W offers an affordable, space-saving solution – either as a single unit up to 150 kW or as a cascade with up to eight boilers and a heating output up to 900 kW. Vitodens 200-W wall mounted condensing boilers are especially suitable for installation in apartment building, commercial or public buildings.

All Vitodens 200-W light commercial boilers now have the option of an extended warranty to 10 years, warranty details as follows:

  • Standard Warranty - 2 years
  • Standard Warranty if installed by a Viessmann Trained Installer - 5 years, extendable to 10 years (fee applies)
  • Manufacturer's warranty details in full

New for 2018 is the underneath Low Loss Header for the Vitodens 200-W 49-150kW range; key features include:

  • Reduced footprint for much smaller installation
  • Easy installation with flow/return connection either on right or left hand side, up or down
  • Manufactured and patented by Viessmann - Details in the Technical Guide

The Inox-Radial heat exchanger made from stainless steel offers high output on a very small footprint. This enables particularly efficient operation with standard seasonal efficiency [to DIN] up to 98 % (Hs) [gross cv] / 109 % (Hi) [net cv].

The Vitotronic 300-K cascade control unit regulates up to eight Vitodens 200-W as a single heating centre. It also automatically matches the boiler output to the heat demand. This means, subject to the prevailing demand, either one boiler modulates or all eight boilers operate concurrently.

We offer the complete range of matching system components for creating cascade systems, e.g. control units with up to eight appliances, fully insulated hydraulic cascades and flue gas headers.
