Expander Buck

The pressure of the liquid inside the radiators, which are connected to the combi and the system, is very important in sending the heat to the room. Many users want to get information from us by asking questions such as What is the expansion tank in the combi. This pressure level allows the fluid to circulate easily in the system. This liquid is generally water. When the water in it is heated, an increase in volume, called expansion, is observed. In this increase, the pressure of the combi increases and endangers the installation and the combi. In order to prevent this, the expansion tank is usually installed in the back of the combi, also known as the storage tank.
