Regular maintenance is essential for the long – term and reliable operation of an electric – heated thermal oil boiler. One of the key maintenance tasks is to check the electric heating elements regularly. Over time, the heating elements may be subject to wear and tear, and signs of damage such as cracks or breakage should be detected early. If a heating element is damaged, it should be replaced immediately to ensure the normal heating function of the boiler.
The thermal oil also needs to be maintained. Periodic sampling and analysis of the thermal oil are necessary to check its quality. If the thermal oil has deteriorated, such as due to oxidation or contamination, it should be replaced. In addition, the circulation pump should be inspected regularly for proper operation. Lubrication of the pump's moving parts is important to prevent mechanical failures.
When troubleshooting, common problems such as insufficient heating may be caused by a malfunctioning heating element or a problem with the control system. If the temperature cannot be stabilized, it may be due to inaccurate temperature sensor readings or incorrect settings in the control system. By carefully checking each component of the boiler system, these problems can be diagnosed and resolved in a timely manner.
