What Does the 3K Bombe Expansion Tank Do?

The fluid circulating in the system loses heat as it returns from the installation to the boiler.

Heat loss causes thermal expansion in the boiler. This reduces the lifespan of both the boiler and the system.

The main function of the 3K bombe expansion tank is to mix the cooled water returning from the installation with the hot water from the boiler, minimizing thermal imbalance.

Using the 3K bombe expansion tank extends the lifespan of your system and boiler.

The 3K bombe expansion tank has three connection sleeves on top where sensors, manometers, and valves can be installed.
