FAQ
Q: What is the expected service life of a carbon crystal heating plate?
A: Under normal indoor operating conditions, the heating plate provides a service life of 8–10 years with less than 1.5% heating efficiency degradation when installed according to the recommended guidelines.
Q: Can the heating plate be cut or drilled during installation?
A: No. The heating area cannot be cut, drilled, or punctured after manufacturing, as this may damage the internal conductive circuit. Custom sizes and mounting holes should be specified before production.
Q: Does the heating plate require regular maintenance?
A: No routine maintenance is required. It is recommended to inspect electrical connections every 12–24 months in commercial installations to ensure long-term electrical safety.
Q: Can the carbon crystal plate be used as the primary heating source?
A: Yes. With appropriate power density selection of 150–400 W/m² and proper insulation design, it can serve as the primary radiant heating system for residential and commercial indoor spaces.
Q: What warranty period applies to the carbon crystal plate, and how are electrical safety failures handled?
A: The plate carries a 5-year warranty against manufacturing defects including insulation failure or heating inconsistency, with confirmed defects resolved through free replacement after review of the batch test log.
Q: How should the heating plates be stored before installation?
A: Store the panels in a dry indoor environment between -10°C and +40°C, keeping them flat in their original packaging to prevent moisture absorption and mechanical deformation.
