1. Simplify installation

In the case of natural circulation, the circulating pressure of the system is due to the poor specific gravity of the water. The circulating pressure produced is usually only a few thousandths of the atmospheric pressure. Therefore, the existence of bubbles in the system will seriously hinder the realization of circulation. After using the circulating pump, heating installation is greatly simplified.

2. Arbitrary layout

In the case of natural circulation, in order to ensure the circulation pressure of the system, the radiator and the cooker are separated from the necessary distance in the direction of gravity, resulting in "the radiator hanging high" or "the stove falls into the ground" and other problems. Using forced circulation, without considering the relative position of radiator and furnace. Even if the furnace is higher than the radiator, it will not affect the circulation of the system.

3. Optimize the system

Because the power of natural circulation is very small, a very thick main pipe is usually used to reduce the resistance of the system. Even so, the system often has problems with circulation or heat dissipation. After the use of the circulating pump, the main diameter can be reduced appropriately, so as to simplify the installation, optimize the circulation, beautify the appearance.

4. Save money

The disadvantage of natural circulation is the low efficiency of the radiator. Under normal conditions, the temperature difference between the top and bottom of the radiator is more than 40 degrees. The forced circulation can reduce the temperature difference between the radiator and the radiator. Based on the same heat dissipation calculation, it is estimated that the radiator can save 20-30%. In addition, each system can achieve considerable cost savings due to reduced mains power.
