Viessmann Vitodens 200-W B2HE-150 in practice
The B2HE-150 fires from 14 to 150 MBH input (4.1 to 44.0 kW), stepping up to the taller 179 lb (81 kg) cabinet shared with the 199. Above 120 MBH it is the size a heat-loss calculation reaches for on larger detached homes and homes with substantial indirect-tank recovery loads.
Like the rest of the B2HE series it is heating-only with domestic hot water handled separately, and it carries the 7-inch colour touchscreen, up to four heating circuits, built-in WiFi and Lambda Pro Plus combustion management at 95% AFUE.
Its minimum fire rises to 14 MBH — against 8.5 MBH on the 85 and 120 — so in a home whose load rarely approaches 150 MBH the smaller models track mild BC weather more closely. Vent runs to about 198 ft (60 m) per the page still apply, which keeps retrofit flexibility.
Best suited to
- Larger detached homes whose heat-loss calculation exceeds 120 MBH
- Homes with high indirect-tank recovery demand on the flagship control platform
- Retrofits needing the B2HE's venting reach (about 198 ft per the page)

Frequently asked questions
How heavy is the B2HE-150?
179 lb (81 kg) per Viessmann Canada, versus 108 lb for the 85 and 120 models. It is also taller and deeper, so the mounting plan changes.
When should I choose the B2HE-150 over the B2HE-120?
When the room-by-room heat-loss calculation and hot-water recovery load genuinely exceed the 120's ceiling. Below that, the 120's lower 8.5 MBH minimum fire gives it the modulation advantage.
Does the B2HE-150 support four heating circuits?
Yes. The B2HE page states the series provides four input connections for heating circuits and third-party controls, and all four B2HE models share that control platform.
