Hot water systems are almost a basic necessity in every household, as people use it for bathing, washing, and cooking. Solar hot water system installations, however, depends on the climate, solar resources, safety measures, and building codes. Installing it by yourself may damage its parts or lead to technical malfunctions. This is why it’s advisable to hire a qualified thermal system contractor to set it up properly.
After that, the maintenance is up to you. If you’re using active solar heating systems, make sure to talk to your contractor for the necessary instructions. Reading the system manual will also give you an idea which parts need regular cleaning. You won’t have a problem with passive systems, though, because these don’t need regular inspection. In addition, if you take care of your hot water systems properly, you’ll only need to replace its electrical components every 10 years.
Occasional inspections and routine maintenance are necessary to keep the systems running efficiently. This way, you can prevent scaling, corrosion, and freezing. Here’s a maintenance checklist to help you:
1. Collector Soiling – If you live in a dry, dusty area, then your system may not perform effectively. Cleaning the collectors at least once a month will keep it running in good condition. Look for cracks in the grazing and check if the seals are intact as well.
2. Collector Shading – Make sure that the collector gets the necessary sunlight. Observe the sun’s rays during mid-morning, noon, and mid-afternoon to know if you need to make adjustments.
3. Plumbing, Ductwork, and Wiring – Check the pipe connections if there are fluid leaks. The ducts should have a durable mastic compound and the wiring connections should be in their proper position.
4. Support Structures – Inspect the area where the solar hot water system is connected. Make sure there are no missing materials that might cause it to fall. Try to test its steadiness to know if there are loose materials as well.
Treat your solar hot water systems like an investment. With proper installation and maintenance, you can use the hot water it produces for a long time. Another good thing is that you’re saved from costly prices, which is the typical case among water heating systems that rely on electricity.
