An integral part of a modern private heating system home is an expansion tank. It allows you to level thermal expansion of the coolant. Experts have calculated that when the temperature rises by 70ºС, the volume of water will increase by 3%. Heated liquid from the pipeline enters the tank, and after As it cools, it goes back to the highway. In the domestic market A wide range of expansion tanks is presented. They differ in volume, design and price. Choose the right one equipment for a specific heating system will help recommendations of our experts.

Recommendations for choosing an expansion tank

Types of expansion tanks. In heating systems can several types of tanks are used.

  1. Open type tanks for heating systems with natural circulation (without booster pump). In that In case the tank is installed at the highest point.
  2. The scope of closed expansion tanks is sufficient wide. It can be open systems without pumps or closed forced circulation lines.
  3. Membrane expansion tanks are today the most advanced equipment. The advantage of such devices is work in automatic mode. The coolant in such a circuit does not in contact with air, so the inner surfaces metal parts are not destroyed.

Volume. Many consumers pick up an expansion tank without calculations, spending money for excess volume. Experts recommend do some simple math.

  1. To calculate the volume of coolant in the heating system it is necessary to take the passport data of the boiler and all radiators, to them add volume of fluid in the pipes. Multiply the resulting figure by 0.1-0.12.
  2. For example, if 100 liters of water are poured into the heating system, then the size of the expansion tank should be 10-12 liters.

Membrane. In modern accumulators an important role membrane plays.

  1. Some manufacturers make it interchangeable, which allows through carry out repairs or scheduled maintenance for a while.
  2. There are expansion tanks where the membrane is non-replaceable. In this case equipment life is limited by durability membranes.

Installation method. Expansion tanks are mounted by two ways.

  1. Vertical installation is easy. Enough tank set on supports or adjustable legs to tackle equipment strapping.
  2. In case of horizontal installation, you will have to mount the tank on the wall or make a special stand. These devices do not always go in the kit.

The editorial board selected the 6 best expansion tanks for the review. All of them are sold in specialized stores in Russia. When distributing the positions, expert opinions were taken as a basis, with This did not go unnoticed by reviews of Russian homeowners.
