Solar Water Heater Maintenance Checklist

Use this Solar Water Heater Maintenance Checklist to inspect components like piping, seals, ducts, and other support structures for efficient operation.

1. Is the shading of the collectors visually checked during the day (mid-morning, noon, and mid-afternoon) on an annual basis?

2. Has vegetation growth or new construction introduced shading that affects performance?

3. Have the collectors been checked for dust and soiling?

4. Is periodic cleaning performed if necessary due to birds, dust, or insufficient rain?

5. Are the collector glazing and seals inspected for cracks or degradation?

6. If the plastic glazing is excessively yellowed, is it replaced?

7. Are plumbing, ductwork, and wiring connections inspected for fluid leaks, loose connections, or degraded seals?

8. Are ducts properly sealed with mastic compounds?

9. Are all valves in the proper operating position?

10. Is the insulation covering pipes, ducts, and wiring intact and undamaged?

11. Is protective wrapping applied to pipe insulation if needed?

12. Are roof penetrations inspected for proper flashing and sealant?

13. Are there any signs of water leakage on the underside of the roof?

14. Are all nuts and bolts securing the collectors to support structures checked for tightness?

15. Is there any corrosion on steel parts, and are they cleaned and painted as necessary?

16. Is the pressure relief valve (on liquid solar heating collectors) actuated to ensure it is not stuck open or closed?

17. In solar air heating systems, do the dampers open and close properly and are they in the correct operating position?

18. Are pumps or blowers functioning properly? Do they activate when the sun is shining on the collectors after mid-morning?

19. If they are not operating, has the controller, pump, or blower been checked for malfunctions?

20. Are the solar water heating controls functioning correctly?

21. If the pump is running at night or failing to run during the day, have the sensors been tested and secured properly?

22. Has the heat transfer fluid (propylene glycol antifreeze) been tested for pH and freeze point and replaced if necessary?

23. If hard water is used, has mineral buildup been addressed with descaling treatment?

24. Are storage tanks inspected for cracks, leaks, rust, or corrosion?

25. If the storage tank has a sacrificial anode, is it replaced at the recommended interval?

26. Has sediment been flushed periodically from the storage system?
