10. Troubleshooting and remedy
Storage water not heating
In case of conventional and regenerative reheating:
– Has the stainless steel heat exchanger been correctly connected?
– Check the boiler circuit for disturbances.
– Check pressure.
– Check circulating pump for function – trapped air.
– Check of regulation. Are heat generators, pumps and temperature
sensors connected correctly?
– Are the temperature sensors positioned at the right
height and functional?
Loss of storage water
Is the storage tank cover closed with the clamps?
Check the storage tank cover – tight?
Is the drain valve on the lower front screw down mounting tight?
Pressure drop in the system
Pressure drop in the first weeks through escaping dissolved
air is normal!
Pressure fluctuations of up to 0.3 bar are normal during operation!
Check system for leak tightness.
Check safety valve for correct installation, leak tightness and function.
Was the bleeding valve shut again after filling?
