2.6 Avoid damage to property

Cooling
If the heating surfaces are used for heating and cool-
ing, the control valves must be suitable for heating and
cooling.
can be expected to form on the heat distribution sys-
tem as the temperature falls below the dew point. If
the heat distribution system is not designed for these
operating conditions, it must be protected by appropri-
ate safety devices, e.g. dew point monitor (purchasa-
ble accessory).
Decommissioning/draining the heating
If the system/heat pump is decommissioned or drained
the condenser and any heat exchangers have been
drained completely for the event of freezing temper-
atures. Residual water in heat exchangers and con-
densers can result in damage to the components.
Completely drain the system and the condenser,
and open vent valves.
Blow them clear with compressed air, if required.
Improper action
Requirements for minimum scale and corrosion
damage in hot water heating systems:
Proper planning, design and start-up
Closed system with regard to corrosion
Integration of adequately dimensioned pressure
retention
Use of deionised heating water (VE water) or with
water corresponding to VDI 2035 only
Regular servicing and maintenance
If a system is not planned, designed, started up and
operated according to the given requirements, there is
Malfunctions and the failure of components, e.g.
pumps, valves
exchangers
components, e.g. heat exchanger, pipes, pumps
Material fatigue
Gas bubbles and
(cavitation)
gas cushion formation
