What is an expansion tank?

Let’s explain the answer to the question of what an expansion tank means with a simple equation. When water is heated, it expands. The expanding water affects the pressure in the closed heating systems it is in and causes the pressure in these systems to increase. Over time, this pressure increases further and various fluctuations occur. These fluctuations begin to damage the system. If the water that expands with the increase in temperature is not taken under control, it will cause leaks in the pipes, boiler and heating system. These leaks, which break out at the weakest point, cause you to not get efficiency from the heating system and cause the system to malfunction. The device designed to prevent this pressure and possible dangers is called an expansion tank. In fact, the expansion tank acts as a “mediator” between the increased heat pressure and the heating system. It allows the increased temperature to be controlled. It reduces the pressure in the system, balances it and helps the system to work at the desired performance. Today, there is an expansion tank in every boiler room. Expansion tanks equalize the pressure in the system. It is a small tank divided into two parts by a rubber diaphragm. The system works as follows; As hot water enters the heating system, the pressure in the system increases. As this pressure increases, the diaphragm in the expansion tank is pushed down. This compresses the air in the tank and creates space for excess water to enter. The excess pressure in the system is reduced, thus preventing the pipes from being damaged.
