Expansion tank for water supply: what is it and what is it for?

An individual hot water supply and heating system is now available in almost every country cottage. Its only drawback is that the batteries dry the air quite a lot, but you can cope with it by simply placing a small aquarium or other container of water in the room.

In addition, this system is quite reliable and does not often need maintenance and repair. The only element that you need to pay attention to is an expansion tank for water supply. If you select or mount it incorrectly, serious problems cannot be avoided. You do not want to be left without heating in the middle of winter?

What it is?

By the way, what kind of tank is this? This is a special tank designed to compensate for the excess pressure in the system that occurs when the temperature of the water rises.

In addition, their second β€œduty” is to maintain optimal pressure in the system. If you need a large heating system or hot water system, their purchase is inevitable.

Principle of operation

When the water in the system is heated to a certain temperature, it expands, and the excess just goes into the tank. Cooling, the liquid goes back into the pipes. Note that the expansion tank for water supply systems is designed so that the water does not come into contact with the inner surface of the walls. To do this, they are covered with a special material based on rubber. The thicker the walls of the tank, the longer its service life.

Additional functions

It is generally accepted that an expansion tank for water supply performs only those functions that directly derive from its name. But the engineers would not forgive themselves if such a quantity of water was used only for circulation through a closed pipe system.

Their very important function is to protect the entire structure from possible hydraulic shocks. Often they combine the role of a fire fighting tank and a tank with a supply of water. This will probably come in handy in the vastness of our country, where utilities love to turn off something.

Installation Notes

It is strongly not recommended to buy and install an expansion tank for water supply, without having completed all the necessary calculations. This can not only lead to the failure of the entire system, but also cause accidents.

Rule two: installation should only be carried out by a certified specialist, and the tank itself must be attached as reliably as possible to a concreted base.

If a suspended expansion tank is used for water supply, then with a device weighing more than 30 kilograms, it can only be mounted on a specially designed and properly reinforced frame.

In addition, we strongly recommend that you install a special fuse limiter that can completely turn off the system if the pressure in it exceeds all limit values.

However, remember, no matter how reliable modern devices are, the risk of their failure always remains.
