The Vitodens 242-F gas condensing storage combi boiler is pre-
pared at the factory for the direct connection of a solar thermal sys-
tem. The solar control module is already integrated and is actuated
via the control unit of the Vitodens 242-F
Fitted with the MatriX-Plus gas burner and stainless steel Inox-
Radial heat exchanger, the Vitodens 242-F offers top technology for
energy efficiency and a high level of heating and DHW convenience
over the long term. The Lambda Pro Plus combustion controller and
the variable speed high efficiency circulation pump ensure perma-
nently high efficiency, reliable operation and low power consumption.
The integral DHW cylinder with 170 l capacity for connecting a solar
thermal system features high solar coverage of over 50 %. This is
achieved by means of its large cylinder capacity and automatic
reheating suppression.
