Product Information

Natural gas and liquid propane gas-fired condensing
heating boiler for weather-responsive operation in closed
loop, forced circulation hot water heating systems for
space heating and domestic hot water (DHW) production.
The Vitodens 222-F, B2TB series boiler comes factory
set for operation with natural gas. For a fuel conversion
to liquid propane gas no conversion kit is required (see
page 16).
The integral primary storage tank 26.5 USG (100 L)
capacity offers the convenience of a separate DHW tank
with approximately twice that volume.
Boiler model must be selected based on an accurate heat
loss calculation of the building. Ensure boiler model is
compatible with connected radiation.
