Expansion tank Cal-Pro 80CP by Zilmet, with a capacity of 80 liters. Every material (liquid, solid, or gas) expands when heated and contracts when cooled. In heating systems, the circulating water heats up and cools down, leading to its expansion and contraction.

When water expands, its volume in liters increases. If the additional liters are not stored, they can increase the pressure to dangerous levels. The expansion tank intervenes by storing the extra liters created after expansion.

It is installed vertically, saving space, and has a base for free installation without additional installation work.

The choice of the correct tank size depends on many factors, such as the water content of the system, system pressure, and the total height of the installation.

Before purchase, it is recommended to consult a specialized plumber for the best solution.
