Selection tables, DHW cylinders

The DHW cylinders with a "-W" in the product name are supplied in
white. The appliances with a "-B" or "-V" in the product name are sup-
plied in Vitosilver (marked in grey in the table).

Vitodens 200-W gas combi boiler
For the DHW connection, connection sets for installation on finished
or unfinished walls are available as accessories. The integral instan-
taneous water heater provides direct DHW heating.
When using galvanised pipes, observe that the instantaneous water
heater is designed as a stainless steel plate heat exchanger with cop-
per solder joints (observe the flow rule).

The table shows that the correct DHW cylinder to DIN 4708 would have
a capacity of 120 litres.

In existing installations (modernisation projects), the risk of electrolytic
corrosion is low, since a protective layer will have formed on the inside
of the pipes.
If DHW should be drawn simultaneously from several points, we would
recommend the installation of a separate DHW cylinder in conjunction
with the gas boiler (see Decision-making aids regarding DHW heat-
ing).
From a water hardness above 3.58 mmol/l and higher, we recommend
the use of a water treatment system in the cold water supply.
