What if the electric current of circulating pump thermal oil heater is lower than normal value?

12 May 2023

If the electric current of the circulating pump in a thermal oil heater is lower than the normal value, it may indicate a problem with the pump or the system. Here are some potential causes and solutions:

1. Low fluid level: If the thermal oil level is low, the pump may not be able to circulate the oil properly, leading to lower current readings. Check the fluid level and add more oil if necessary.

2. Clogged filter: A clogged filter can restrict the flow of thermal oil, causing the pump to work harder and draw more current. Check the filter and clean or replace it as needed.

3. Pump malfunction: A malfunctioning pump may not be able to circulate the thermal oil properly, leading to lower current readings. Check the pump for any signs of damage or wear, and repair or replace it as needed.

4. Electrical issues: Electrical problems, such as a faulty motor or wiring issues, can also cause the circulating pump to draw less current. Check the electrical connections and components, and repair or replace as needed.
