Vitodens 333-F, type FS3B
3.1 Product description
3
The Vitodens 333-F storage combi boiler combines the benefits of the
Vitodens 300-W with the high DHW convenience of a separate DHW
cylinder.
With the MatriX gas burner and the stainless steel Inox-Radial heat
exchanger, the Vitodens 333-F offers top technology for many years
of energy efficiency and high heating and DHW convenience. The
Lambda Pro Control and SMART modules, well-known from the
Vitodens 300-W, plus the variable speed high efficiency DC pump,
ensure permanently high efficiency, reliable operation and low power
consumption.
The integral stainless steel 100 l litre primary store offers the same
DHW convenience as a separate DHW cylinder approximately twice
the size.
