Do you need solar water heater system maintenance or repairs? Here are the common symptoms/causes

Low water pressure

If you’re not getting enough hot water from your solar system, low water pressure might be the root of the problem. This could be caused by a blockage in the pipes, a failing pump, or an issue with the pressure relief valve. To fix this, you might need to clear out any blockages, replace a faulty pump, or have a plumber adjust the pressure relief valve.

Lack of Hot Water

One of the most common issues homeowners face with their solar hot water systems is a lack of hot water. If the sun isn’t shining or if your system is undersized, you may find yourself without hot water. One solution is to install a backup heating system, such as an electric or gas heater.

Leaks

Leaks can be a real problem with solar hot water systems, but luckily they are often easy to fix. Check the connections between the pipes and the tank to ensure they are tight, and check the pipes themselves for any visible leaks. If you can’t find the source of the leak, it’s best to call in a professional.

Inefficient Heating (Reason #2)

If your solar hot water system is not heating effectively, it may be due to a build-up of scale or sediment in the tank. Flushing the tank periodically can help remove sediment and improve your system’s efficiency.

Air in the System

If your solar hot water system has become filled with air, it might not be able to circulate or heat the water properly. To fix this, you’ll need to bleed the air out of the system or have a professional plumber do this for you.

Water Too Hot or Too Cold

If the water from your solar hot water system is too hot or too cold, it may be due to a faulty thermostat or sensing unit – check these components and replace them if necessary. Similarly, if your solar collectors are not functioning properly, your whole solar hot water system will suffer. Check the collectors for any signs of damage, such as cracks or dents, and replace them if necessary.

Pump Not Working

If the pump in your solar hot water system is not working, the water won’t circulate properly and your system won’t function. Check the pump for any visible signs of damage, and test it to ensure it’s working properly. If not, it may need to be replaced.
