    What can go wrong with solar thermal panels?

    Solar thermal panels are designed to harness sunlight and convert it into heat energy for various applications, such as water heating and space heating. While they are generally reliable and efficient, several issues can arise that may impact their performance or functionality, particularly in older systems.

    Common solar thermal problems include:

    • Noisy pump
    • Broken pump
    • Overheating
    • Water not heating
    • Re-gassing
    • Pressure fluctuations
    • Water leaks
    • Control centre malfunction
    • Low anti-freeze
    • Air locks
    • Atmospheric corrosion
    • Coil problems

    If you notice a drop in your solar thermal system’s performance, it’s important that you address the problem as soon as possible. The longer you ignore the issue, the worse it can become and the more savings you’re likely to miss out on as a result. Contact our team to arrange a call out on 0330 0124 2941.

    Solar thermal panels - repair or replace?

    Are your solar thermal panels unsuitable for your property?

    Many evacuated tube systems are designed to heat large volumes of water such as swimming pools – much more than the average household water cylinder holds.

    This means that they are easily prone to overheating when installed on domestic properties and require frequent power flushing to maintain efficiency. You will likely find that a brand new flat plate solar thermal system is therefore a much better use of your money than an endless cycle of repairs.

    We don’t just repair solar thermal systems; we install them too. We only use the best technology and components, so you can rest assured that you’ll be left with a solar thermal system that will perform for years to come.

    We also carry out a FREE power flushing service as part of our installation service. Call us today to speak to a member of our team on 0330 0124 2941.

    Prevention is better than cure

    It’s better to be safe than sorry. Since solar thermal panels have no moving parts and are generally out of sight, you may have been inclined to leave their performance to chance, rather than detailed inspection and review.

    Our advice to customers is that a solar thermal system requires a maintenance review every year, at which time its power-generation performance is calibrated, and every electrical and plumbing appliance inspected and tested to ensure optimum performance.

    Don’t leave your solar thermal system’s performance to chance. We offer an excellent thermal maintenance service, complete with 12-month subscription, so you can rest assured that your panels are in capable hands.

    Solar Thermal Repair FAQs

    What is solar thermal power flushing?

    Solar thermal power flushing is a maintenance process used to clean and restore the efficiency of a solar thermal heating system. Solar thermal panels that are exposed to extended periods of overheating usually require power flushing more frequently.

    This procedure involves circulating a cleaning solution through the system’s components to remove accumulated debris, sediment, scale, or other contaminants that can hinder the system’s performance. Power flushing is typically performed when a solar thermal system is experiencing reduced heating efficiency or other operational issues.

    Why are my solar thermal panels overheating?

    There are several reasons why your solar thermal panels may be overheating, but the most common is that your system is not the right design or size for your needs. If your solar thermal panels generate more heat than is required to heat your water cylinder, they can overheat.

    What happens when solar thermal panels overheat?

    In the absence of consistent hot water demand, the temperature within a solar thermal system can swiftly escalate. When the temperature reaches 200°C, the glycol in the system undergoes a transformation into a viscous, tar-like substance that can cause a complete blockage. In many instances, rectifying this issue necessitates a complete system replacement. If not, power flushing will be required at a minimum.

    Why is my solar thermal pump noisy?

    If your solar thermal pump is making noise, several factors could be contributing to the issue:

    • Air trapped in the system
    • Inadequate mounting of the pump
    • Worn out pump components
    • Issues with electrical wiring
    • An issue with pump sizing

    If your solar thermal pump is noisy, our team can diagnose the issue and provide a swift solution.

    Why is my solar thermal system not heating my water?

    There could be several reasons why your solar thermal system is not heating your water effectively:

    • Lack of Sunlight
    • Air lock or blockage
    • Malfunctioning pumpThermostat or control issues
    • Collector positioning
    • Collector contamination

    If your solar thermal system is not heating your water, our team can diagnose the problem and provide a swift solution.
