    Fernox Solar Cleaner 500ml

    Restore the Performance of Your Solar Thermal System

    Over time, solar thermal systems can lose efficiency as heat transfer fluid degrades and contaminants build up inside the pipework. This build-up can reduce heat transfer, increase system wear and affect overall performance. Fernox Solar Cleaner 500ml helps remove these deposits, preparing your system for fresh heat transfer fluid and restoring efficient operation.

    Developed specifically for solar thermal heating systems, Fernox Solar Cleaner circulates through the system to break down contamination and remove degraded fluid residues. As a result, it helps improve circulation and supports efficient heat exchange throughout the installation.

    Using a dedicated solar cleaner before replacing the heat transfer fluid helps maximise the performance of your renewable heating system. Clean internal pipework allows the new solar fluid to work more effectively, helping maintain reliable operation and extend the life of key components such as pumps, heat exchangers and collectors.

    Fernox Solar Cleaner is easy to dose and works with a wide range of solar thermal installations. Whether you’re carrying out routine maintenance or servicing a system that has experienced reduced efficiency, it provides a professional solution trusted by heating engineers.

    Manufactured by Fernox, a recognised leader in water treatment and renewable heating chemicals, Solar Cleaner 500ml supports long-term system performance while helping protect your investment in renewable energy technology.

    THE PROBLEM IT SOLVES

    As solar heat transfer fluid ages, it can degrade and leave deposits inside the system. These contaminants restrict circulation, reduce heat transfer and lower system efficiency.

    Fernox Solar Cleaner removes these residues before new solar fluid is added. As a result, your solar thermal system can operate more efficiently while helping protect key components from unnecessary wear.


    WHY CHOOSE THIS PRODUCT?

    Routine maintenance helps every solar thermal system perform at its best. Fernox Solar Cleaner removes contamination that ordinary flushing may leave behind, allowing fresh heat transfer fluid to circulate freely.

    Using the correct cleaner before replacing solar fluid helps improve efficiency, reduce maintenance issues and extend the working life of your renewable heating system.


    PERFECT FOR

    ✔ Solar thermal heating systems

    ✔ Renewable heating maintenance

    ✔ Heating engineers

    ✔ Solar installers

    ✔ Heat transfer fluid replacement

    ✔ Routine servicing

    ✔ Domestic renewable systems

    ✔ Commercial solar thermal installations


    WHEN SHOULD I USE THIS PRODUCT?

    Use Fernox Solar Cleaner whenever you’re replacing the heat transfer fluid in a solar thermal system or carrying out routine maintenance.

    Cleaning the system before adding fresh solar fluid helps remove contamination and ensures the new fluid delivers maximum performance.
