Expansion tank
After connecting the expansion tank to the system, if the temperature rises, the volume of the water also increases, which begins to fill the membrane during its expansion.
The volume of the water increases until the maximum temperature when reached, the membrane no longer fills almost the entire tank. The membrane prevents the water from coming into contact with the inner surface of the tank.
When the temperature of the water in the system starts to decrease and with it its volume, thanks to the air pressure in the overpressure chamber, the water from the expansion tank flows back into the heating system, until , until the initial volume is reached and the cycle starts again.

Expansion tanks - Essential accessories of the heating system
Expansion tanks are indispensable elements of modern heating and water supply systems. These devices deal with the change in volume of water that comes with increasing and decreasing temperature. If the temperature rises in your heating system, the volume of water increases, which the expansion tank can flexibly handle. The membrane inside the tank ensures that water does not come into contact with the inner surface of the tank, which extends the life of the tank.
When the temperature drops, the air pressure in the membrane allows water to flow back into the heating system, thus maintaining a stable system. Expansion tanks contribute to safety and efficiency by preventing excessive pressure build-up and potential damage to the heating system.
In our webshop, you can find expansion tanks of various sizes and types, ranging from 5 liters to 5000 liters. Whether you are looking for a tank for a heating, solar collector, or hydrophore system, you will definitely find the right one with us.
These tanks are ideal for households or businesses that want to maintain a flexible and efficient system while minimizing maintenance and repair costs. The easy installation and durability of the tanks ensure problem-free operation in the long term.
Why is an expansion tank important?
As the temperature of the water in the heating system rises, the volume of the water also increases. The expansion tank ensures the storage of excess water, preventing a rise in pressure in the system. This protects the heating boiler, pipes and fittings from damage.
Advantages of expansion tanks:
- Prevents pressure fluctuations:The expansion tank balances the pressure in the heating system, preventing boiler overload and cracking of pipes.
- Ensures the efficient operation of the heating system:Through stable pressure conditions, the heating system operates more efficiently and consumes less energy and has a longer lifespan.
- Prolongs the life of the heating system components:The expansion tank prevents overpressure, which preserves the boiler, the integrity of pipes and fittings.
- Easy installation and maintenance:Expansion tanks are easy to install and require minimal maintenance.
