-
Visual inspection for potential leaks in the roof
-
Visual inspection of the thermal insulation on pipework
Solar heating circuit
-
Visual inspection for potential leaks in the solar circuit (joints)
-
Colour check of the ANRO heat transfer medium
-
pH value test of ANRO heat transfer medium only in case the medium has
turned brown; poss. replacement
-
Frost protection level of the heat transfer medium checked.
-
Safety valve tested
-
Solar expansion vessel inlet pressure tested (for this, release pressure from
expansion vessel)
- In case of noisy pumps or system pressure fluctuations vent the system; for
this, block the gravity brake
-
System pressure in a cold system state (see system operating pressure)
-
Reactivate the gravity brake
Solar cylinder and DHW circuit
-
Protective anode inspection
-
Check for scale build-up in the cylinder and on the thermostatic mixing valve;
poss. carry out de-scaling
-
Check the anti-scalding protection (thermostatic mixing valve or via the
maximum cylinder temperature limit)
Control systems
-
Check control parameters and display values for plausibility
- Solar circuit pump running - circulates (poss. adj. and checking on the flow meter)
-
Temperature of boiler boosting tested
-
Option: DHW circulation pump runtime checked
