2.5 Avoid damage to property
Improper action
Requirements for minimum scale and corrosion dam-
age in hot water heating systems:
Proper planning, design and commissioning
Closed system with regard to corrosion
Integration of an adequately dimensioned pres-
sure maintaining device
Use of demineralised heating water (VE water) or
water corresponding to the VDI 2035 norm
Regular servicing and maintenance
If a system is not planned, designed, started up and
operated according to the given requirements, there is
a risk that the following damage and faults will occur:
Malfunctions and the failure of components, e.g.
pumps, valves
Internal and external leaks, e.g. from heat ex-
changers
Cross-section reduction and blockages in compo-
nents, e.g. heat exchanger, pipes, pumps
Material fatigue
Gas bubbles and gas cushion formation (cavita-
tion)
coatings, deposits, and associated noises, e.g.

es, the heat exchangers will be damaged.
Fill the system with deionised heating water
(VE water) or with water corresponding to the VDI
2035 norm only (low-salt operation of the system).
3 Operation and care
NOTE
The device is operated via the control panel
of the heating and heat pump controller
( operating manual of the heating and
heat pump controller).
3.1 Energy and environmentally
conscious operation
The generally accepted requirements for energy con-
scious and environmentally conscious operation of a
heating system also apply to use of a heat pump. The
most important measures include:
No unnecessarily high domestic hot water tem-
perature (note and follow local regulations)
Do not open windows with just a gap or tilt open
(continuous ventilation), but instead open wide for
a short time (shock ventilation)
Always ensure that the controller settings are cor-
rect
