Viessmann Vitodens 200-W B2HA-399
The Vitodens 200-W B2HA-399 opens the larger B2HA chassis: 113,000 to 399,000 BTU (33 to 117 kW) of input in the 298 lb wall-hung condensing boiler, with a printed thermal-efficiency row (ANSI Z21,13/CSA 4.9) of 93.9%.

Viessmann Vitodens 200-W B2HA-399 in practice
The B2HA-399 is the first model in the B2HA line's second chassis group: with the B2HA-530 it fires from a 113,000 BTU (33 kW) minimum input — higher than the 71,000 BTU (21 kW) floor of the B2HA-285/311/352 — up to 399,000 BTU (117 kW) maximum, and it weighs 298 lb (135 kg).
Cabinet dimensions grow to 23½ x 27 x 44½ inches (600 x 689 x 1128 mm), and the page's spec table prints the model's efficiency as a thermal-efficiency row of 93.9% per ANSI Z21,13/CSA 4.9 — slightly below the 94.5% it prints for the B2HA-311 and B2HA-352, and a differently labelled row from the 92% AFUE it prints for the B2HA-285.
The boiler keeps the wall-hung MatriX cylinder burner and Inox-Radial stainless steel heat exchanger, on natural gas or liquid propane with no fuel-conversion kit required. As on the whole page, the technical table interleaves legacy B2HB rows with the current B2HA rows; only the B2HA-399 figures are used here.
Best suited to
- Large homes and light-commercial plants whose load calculation exceeds the 352's ceiling
- Projects needing the larger 298 lb B2HA chassis for headroom toward 530 MBH
- Cascaded or common-vented multi-boiler plants (up to four units common-vent per the page)
