Flexiheat support FAQ

Common questions about manuals, registration, and support for this brand.

  • Where can I find the identification details for my Flexiheat boiler?

    A serial or identification number is printed on the boiler's identification label. This information is required for every interaction with the manufacturer or when booking an authorised service call.

  • How often should I service my Flexiheat electric boiler?

    An initial inspection of the device's electrical contacts should be performed 3 months after starting operation, as elements can loosen during transport. After this, regular maintenance should be performed every 6 months by a qualified professional.

  • Do Flexiheat boilers have built-in frost protection?

    Yes, models like the Thermo Max feature built-in frost protection. If the boiler is not actively used during the winter, the main power should be left on so the system can automatically protect against freezing if the water temperature drops below 8°C.

  • Can Flexiheat unit heaters operate in highly humid environments?

    Standard Flexiheat unit heaters should not be used in areas where the relative humidity exceeds 95% or if the air dust concentration is above 3mg/m3.
