Output range
Boilers within the range offer the following
DHW outputs of 19 kW, 26 kW, ideal
for refurbishments

Award winning control unit
The Vitodens 242-F is supplied as standard
with the Vitotronic 200 HO1B weather
compensation controller with 7 day
programming
The control can be sited up to 5 m
away from the boiler enabling installation
in areas with restricted access, e.g. If the
boiler is installed in a garage or loft
Cylinder Loading System (CLS)
Most unvented cylinders use a heating coil
to heat up the cylinder. The CLS technology
replaces the coil with a plate heat exchanger.
A DHW pump circulates the cold water from
the bottom of the cylinder, through the plate
heat exchanger and puts the hot water back
to the top of the cylinder.
