The Fiamma A20 expansion vessel is a component designed to improve the water system in motorhomes, caravans, and campervans. Its design reduces pulsations in the circuit, stabilizes pressure, and provides a smoother water flow. As a result, the Fiamma A20 expansion vessel makes using the tap more comfortable, quieter, and with less vibration.

Improved performance for the water pump

This expansion vessel helps prevent the pump from constantly switching on and off. This reduces daily wear and tear and also reduces noise during operation.
Furthermore, it comes pre-charged to 0.9 bar , although it is possible to adjust the pressure using the air valve if the system requires it.
In this way, it adapts well to different types of installations.

Advantages of the Fiamma A20 expansion vessel

• Continuous flow: reduces water pulsations.

• Longer lifespan: the pump works with less effort.

• Lower consumption: fewer starts mean less energy used.

• Compatible: Works with Fiamma pumps and other 12V brands.

• Adjustable pressure: thanks to its accessible valve.

• Compact design: ideal for small spaces.

• Quick installation: includes the necessary fittings.

Installation and maintenance

The Fiamma A20 expansion vessel is easy to install next to the pump. Its small size also makes it easy to fit into a tight space.
Maintenance is also simple. You only need to check the pressure from time to time to ensure that the flow remains stable.
For this reason, it is a practical accessory for both new users and those looking to improve their current system.

Thanks to its ability to smooth water flow and reduce vibrations, it becomes an essential component for improving the comfort and efficiency of any onboard water system.
