Does it matter what the size of the earth heating water tank is, and what is the role of the earth h

The size of the earth heating tank depends on the actual situation, and the bigger is not always better.

A terraisphic tank is also called an expansion tank. It can hold the water in the circuit system that expands due to heating, and when the water cools down in size, it can also flow back into the system, ensuring that the circuit is filled with water at all times, promoting smooth circulation.

The tank should also have a function, which is often overlooked by the installer, that is, the tank should be ready to drain the original gas in the pipeline and the gas separated from the water due to heating.

Most installers prefer to install the tank pipe on the return pipe, and the result is that after the water is heated, the gas in the pipe runs upwards and concentrates at the highest part of the pipe section, where an exhaust valve must be installed. But when in use, you can't always open the exhaust valve to vent the air. Because the gas in the pipe expands sharply when heated, the pressure is very high, which will cause the water to jump out of the tank.

This is the disadvantage of the tank being placed on the return pipe. If the tank is installed on the water pipe, the gas can escape smoothly. Of course, for the water tank to be placed outside the heating room, due to the conduction of heat, it will lose part of the heat, reducing the heating effect.

Therefore, the installation of the water tank should also be properly placed in the heating room.

Placing the tank on the upper pipe will not hinder the circulation. Many people believe that the power of the water circulation of the earth heating is due to the pressure of the water in the tank, so it is not right to install the water tank on the return pipe and try to place the water tank as high as possible. The power of the water circulation of the earth heating is determined by the temperature difference of the water and the vertical distance difference between the boiler and the radiator, that is, the larger the temperature difference and the higher the radiator (or the lower the boiler), the faster its circulation.

Regardless of whether the tank is installed on the upper or return pipe, the positive pressure on the system becomes offset by two equal forces flowing in the same and opposite directions. Therefore, the position of the water tank does not affect circulation, and placing it on the water supply pipe does not prevent the hot water from rising.

Earthen heating tank, generally speaking, 1 3 liters is enough.

The function of the earth heating water tank is mainly to facilitate the addition of water, maintain the water level, avoid burning dry, and the evaporation of the earth heating is very small.

Secondly, when it is put into use, it is necessary to avoid overflow due to the increase in volume due to the rise of water temperature.

At the end of the day, one is the water inlet, and the other is the buffer tank. If it's too big, it will waste heat.

The main role of the earth heating tank:

1. As a water bucket, add water to the heating system;

2. The amount of thermal expansion after the water heating of the containment system:

3. Constant pressure for the system.
