What should I do if the pipe heater has poor circulation?

A pipe heater is an electric heating device that uses a heating tube within a cylindrical, insulated container to heat gases and liquids. Pipe heaters offer fast heating speeds, excellent insulation, and high heating temperatures.

What should we do if our pipe heaters experience poor circulation? How can we resolve this?

Solution: Generally, opening the bleed valves on the heater and the pipe to release the air in the pipe can resolve the problem. (Note: There must not be any large bends in the pipe, otherwise circulation will be disrupted.)

Common problems with pipe heaters include the following:

1. The heater may not function properly upon initial use.

2. If the water circulation is poor during operation, the heater body may overheat. At this point, the manual reset thermal fuse on the heater will automatically trip, stopping the oil supply and allowing the heater to cool gradually.

3. The indicator light does not illuminate when the heater is turned on.

Solution:

1. Ensure the heater water valve is open and the heater rotates smoothly. The first time the heater is installed and operated, it may not operate properly due to a lack of oil in the heater oil pipe. It should function normally after a few attempts. The glow plugs and fuel filter generally do not require cleaning. However, if the heater is dripping oil, smoking, and not burning, remove the glow plugs and filter, reinstall them, and then restart the heater.

2. If this occurs, check that the heater water pipe is unobstructed and not compressed. Then, press the fuse reset button in the center of the rubber cap and restart the unit.

3. Check that the main power supply is on, the heater fuse is not blown, the wiring harness is in good contact and secure, and the control box is not damaged.
