FAULT
CAUSE
SOLUTION
No or insufficient domestic hot water
production
Unusually high draw of DHW.
- Check.
Water leaks in the DHW distribution
circuit.
- Check.
Collector glass covered in dust or
leaves.
- Clean.
The level of heat transfer liquid in the
circuit has dropped as the result of leaks
from the unions or because of over-
temperature during extended periods of
disuse.
- Top up the circuit with water/glycol mix
and bleed any air out.
Air bubbles have formed inside the
circuit and are impeding natural
circulation.
- Bleed the circuit by loosening the up-
permost union on the short pipe until
liquid comes out.
- Top up to replace any lost liquid.
Vibrations
Loose screws.
- Tighten the screws.
DISPOSAL
When the system is no longer needed, do not abandon it in the environment, but dispose of it through appropriate channels and
in compliance with applicable legislation.
