Viessmann Gas Boilers

Viessmann Gas Boilers: Viessmann gas boilers provide optimum energy use, which results in the maximum savings for you on your building’s energy bills.

Viessmann gas boilers are some of the most economical and clean ways to generate heat in any commercial building and can significantly reduce your monthly heating bills, as well as your environmental footprint.

Viessmann doesn’t just make individual commercial heating equipment and components that meet the high Viessmann standards for quality, reliability, and effectiveness. All Viessmann products are part of a matching concept, where each component perfectly complements the rest. Only the perfect interaction of system integrated components draws out the maximum potential of our innovative leading technology.

Viessmann system technology includes everything you need for a reliable and economical commercial heating system. The Vitotronic control unit with remote control, the powerful Vitocell DHW tanks for best DHW convenience, to high-quality solar thermal systems for cost-saving heating.

Vitodens 200-W Cascade Systems

Prefabricated Viessmann gas boiler systems with Vitodens 200-W gas-fired condensing boilers. Rated input: 32 to 4240 MBH

Outstanding performance with Vitodens 200-W and Lambda Pro combustion management system. Lambda Pro ensures maximum efficiency by automatically adjusting the gas and combustion air ratio.
Maximum efficiency with high turndown that precisely matches load.
Simplified boiler system layout as manifold and Low-Loss Header provides a complete primary loop.
Multiple boilers secure against interruption of heating plant operation.
Boilers easily assembled and hydraulically connected prior to installation with prefabricated manifold.
Flexible installation with multiple manifold configurations: wall-mounted, floor standing, corner or back-to-back. Right or left-mount Low-Loss Header acts as hydraulic break and helps eliminate air and debris.
Ideal for small or difficult-to-access boiler rooms or facilities with narrow halls and stairwells.
All serviceable components easily accessible from the front.
No pipe or manifold sizing required.
Offered in a packaged system.
Common venting up to four boilers.

VITOCROSSAL 200

Gas-fired condensing boiler with fully-modulating pre-mix cylinder burner. Rated input: 133 to 2245 MBH (single) / 17960 MBH (cascade)

Extremely low NOx emissions and quiet operation from new fully-modulating Viessmann pre-mix cylinder burner.
Wide modulation range of 5:1 turndown ratio precisely matches load conditions.
Pre-assembled burner simplifies installation and commissioning.
Multiple venting possibilities with installed air intake kit for direct or chimney venting PP(s) or stainless steel up to 198 ft. of vent length.
Common venting up to four boilers.
Gas fuel flexibility (NG/LPG/LNG) with a simple electronic conversion.
Low inlet gas pressure requirement (NG) as low as 4 inches of water column for compatibility with a range of supply pressures.
Large water content extends burner run time and reduces cycling.
No dedicated boiler pump required due to extremely low water pressure drop through the heat exchanger – no low-loss header required.
Generous stainless steel heat transfer surface area for maximum heat extraction.
Seamless integration with building management systems.

VITOCROSSAL 300

CA3B Series high-efficiency, gas-fired condensing boiler with Inox-Lamellar heat exchanger surface made of high-grade stainless steel. Rated input: 2500 to 6000 MBH
