High Efficiency, Clean Combustion

The fully modulating MatriX‑Plus burner with Lambda Pro combustion control continuously optimizes the air‑to‑fuel mix—even as gas quality changes—helping the system run efficiently and cleanly at up to 95% AFUE.

Right‑Sized Modulation For Real‑World Loads

With a 14–199 MBH input range, the B2HE‑199 can cruise on milder spring/fall days and ramp up for peak demand. That reduces short‑cycling, improves comfort, and helps components last.

Compact, Wall‑Hung Design

At roughly 17‑3/4" wide with a shallow depth, Vitodens 200‑W saves valuable floor space and fits tight mechanical rooms. Front access to components keeps annual service straightforward.

Flexible Venting For Retrofits

Choose 80/125 mm concentric or 3" polypropylene (PPS) two‑pipe systems for long runs and tricky layouts. Use sealed direct‑vent or draw room air where code allows.

Smart 7" Touchscreen With WiFi

The integrated 7" color touchscreen with built‑in WiFi connects to the ViCare app for remote control, schedules, and alerts. Outdoor reset and multi‑circuit capabilities help tailor comfort room by room.

Ready For Indirect Domestic Hot Water

Pair the B2HE‑199 with a Viessmann or compatible indirect tank for abundant hot water while keeping the boiler focused on space heating.
