Water 08-4
Hot water supply
Hot water is supplied by means of the hot-air heating system
with its integrated hot-water boiler
(see also Chapter 10.2) ;
the options for settings are described on p. 10-05 “Changing
the hot water temperature”.
The boiler will automatically empty itself via a safety or outlet
valve if there is danger of frost
(see also 10-13 Frost Control).
Position of the Frost Control valve
The Frost Control valve is always located directly by the
model-specific place of installation for the hot-air heating
system.
The non-electric safety or drain valve will automatically
open at temperatures under approx. 3°C and drain the
boiler contents via a drain nozzle.
If the cold water system is operated without the boiler the
boiler tank will still fill with water. In order to avoid frost
damage the boiler must be drained via the drain valve,
even when not in use.
