When Is Solar Water Heater Maintenance Necessary?

Like a standard tank water heater, solar water heaters require an annual flush to eliminate sediment buildup and ensure your system operates as efficiently and reliably as possible.

While you should aim to schedule solar water heater maintenance at least once a year, it’s particularly important to consider a tune-up after severe weather conditions like heavy storms or extreme temperatures, which can damage components or affect efficiency.

If it’s been over a year since your last solar water heater maintenance, call 602-787-3956 to schedule an appointment
