Expansion tank VAO 50 by the company Aquasystem, with a capacity of 50 liters. Any material—liquid, solid, or gas—expands when heated (i.e., its volume increases) and contracts when cooled. In plumbing systems, the circulating water constantly heats and cools, leading to its continuous expansion and contraction.

When water expands, its volume in liters automatically increases, and the extra liters, if not stored somewhere, will increase the pressure to high and dangerous levels. At this point, the expansion tank intervenes, responsible for storing the extra liters created after expansion.

It has a special membrane that ensures the water is potable. It is installed horizontally and requires a little more space compared to a vertical tank.

Finally, selecting the right size tank is a function of several factors, such as:

• The water capacity of the entire installation
• The system pressure
• The total height of the installation

In any case, before proceeding with a purchase, you should consult a specialized engineer.
