Smart, Clean Combustion
Viessmann’s MatriX‑Plus burner with Lambda Pro/Pro Plus automatically tunes combustion for gas quality, vent length, and altitude—delivering quiet operation and low NOx performance.
Quiet, Space‑Saving Wall Mount
A slim 17‑3/4"‑wide cabinet and front‑access components simplify installs and annual service. Zero‑clearance design makes it easier to fit tight mechanical rooms.
Flexible Venting For Tricky Layouts
Choose 80/125 mm concentric or 3" two‑pipe venting with generous equivalent lengths (configuration‑dependent), so you can route flue and intake through a sidewall or roof to suit the space.
Ready For Indirect Hot Water & Multi‑Zone Control
Pair the heating‑only B2HE‑85 with a Vitocell or other indirect tank for abundant domestic hot water. The onboard control supports outdoor reset and can coordinate multiple heating circuits with the right accessories.
