Overheating becomes extreme when the film temperature of the fluid rises its optimal maximum. The liquid inside the controller absorbs the heat. Use of cheap quality liquid cannot absorb the heat properly. As a result, the controller becomes overheated and you are deprived of a comfortable temperature. On the other hand, high-quality temperature controller does not become overheated.

Maybe, you were not aware of the fact that you have to face these problems. Contamination happens because of foreign in the system. Cheap controllers have very limited cleaning systems that do not let dirt and dust to be cleared. It makes the air contaminated.


To maintain the flow of temperature is the important function of temperature. As the flows reduce, temperature also fluctuate. The device can be overheated within minutes. So, the reduction of flow can cause a problem in getting a comfortable temperature. You have to face this problem in cheap temperature controller.


Cheap temperature controllers require high maintenance to keep it working. You may need to clean it 3-4 times a month. You have to check everything of it regularly. Overall, the maintenance of this device may be very tough for you.
