4. Operation and Device Construction
4.1 Mode of Action
The Imersion Heater Principle
One to three heater elements (Pos. 8 in the exploded view,
please see cover foldout) are placed in a closed cylinder and
connected to alternating current. The cylinder is filled with tap
water, fully demineralized water or partially softened water. Heat
generated by the heater element increases water temperature to
approx. 100°C.
When fully demineralized water is used, the feed water is practi-
cally free of minerals. This ensures long life for the cylinder and
heater elements since virtually no mineral deposits can settle or
build up. Fully demineralized water minimizes the number of ser-
vice / maintenance checks.
When tap water is used, some of the minerals dissolved in the
water will settle in the cylinder as solids of various compositions.
Most of these scale deposits are removed by periodic flushing or
use of a heavy-duty blow-down pump. See section "Servicing
During Operation with Tap Water".
The generated steam has a temperature of about 100°C and
minimal positive pressure ("pressureless” steam). It is virtually
demineralized and germ-free.
