Short description

Enamelled domestic hot water (DHW) tank
SKL 400 with two large heat exchangers
(bivalent) perfectly suited for the
application of solar systems. In
monoenergetic operation, the heat
exchangers can be connected for
increased efficiency and to increase
system efficiency, e.g. in condensing
boilers. Durable, highly resistant
two-layer enamelling with additional
magnesium protective anode. Standard
with thermometer, cleaning flange,
circulation connection and connection
for an electric heating element. Low
heat loss due to high-quality foam
