How should a shared solar hot-water system be maintained?
Follow manufacturer instructions and arrange competent periodic checks of collectors, pipes, valves and other system components.
A shared system is more than panel cleaning. It may include pipes, valves, non-return devices, pressure reducers, pumps and safety components. Low temperature, abnormal pressure or leakage needs diagnosis rather than cosmetic cleaning.
An annual professional visit is often a reasonable planning starting point, but the actual frequency must follow the manufacturer, installer and system design. Interim collector cleaning may help in Eilat, provided roof access and working methods are safe.
Sound management distinguishes routine work, a service-provider visit and an inspection reserved for an authorised professional. Each system should have a file, next due date, responsible party and open-defect status so that warranties and required work are not lost.
Three points to check
- Manufacturer and installation file
- Leak, pressure and flow checks
- Record of replaced parts
