Prices depend on sizing, venting and piping in your home, so we quote every installation.
Sizing: the right size comes from a room-by-room heat-loss calculation, not the size of the old boiler or a rule of thumb. Oversized boilers short-cycle and waste fuel; steam systems are sized to the connected radiation instead. See how we approach boiler installation.

Ideal For
Luxury estates in Old Westbury, Brookville, and Great Neck
Expert Review: Viessmann Vitodens 200-W
The Viessmann Vitodens 200-W achieves 98% AFUE—the highest efficiency available in residential boilers. For luxury homeowners in Old Westbury, Great Neck, and Brookville, this German-engineered masterpiece delivers meaningful fuel savings over its 30+ year expected lifespan. The Inox-Radial stainless steel heat exchanger is specifically designed to resist Long Island's hard water and coastal salt air.
Lambda Pro combustion control continuously optimizes the air-fuel ratio, maintaining peak efficiency regardless of gas quality or weather conditions. The WiFi-enabled Vitoconnect allows monitoring from anywhere—perfect for second homes or snowbirds.
Parts availability requires planning. While F.W. Webb can source most components, specialty items ship directly from Germany with 3-5 day lead times. We strongly recommend an annual maintenance contract for priority service.
The 12-year heat exchanger warranty reflects Viessmann's confidence in their build quality. For coastal communities like Long Beach and Point Lookout, the marine-grade stainless construction resists salt air corrosion that damages lesser units.
Our recommendation: The Vitodens 200-W is worth the premium investment for homeowners who prioritize maximum efficiency, German engineering, and 30+ year durability. Best suited for estates over 4,000 square feet where the fuel savings justify the upfront cost.

Sizing & Installation Notes
Condensing boilers like the Vitodens 200-W reach their rated efficiency only when return water runs cool enough to condense flue gases. We check your radiation and design water temperatures so the unit actually condenses in your home, not just on the spec sheet.
Every Viessmann installation starts with a free in-home assessment covering the heat-loss calculation, venting and chimney condition, and gas or oil supply sizing. Learn more about our boiler installation process, or see current rebate and incentive programs that may apply.
