Expansion vessel round 6L De Dietrich 711579400

The expansion vessel round 6L is a compact pressure tank designed to accommodate thermal expansion in closed-loop heating systems. With a 6-liter capacity, it helps maintain stable system pressure by absorbing excess water volume as it heats up, preventing pressure spikes and protecting components like valves and pipes. This round vessel is suitable for many boilers and heating installations where space is limited. Replacing a faulty expansion vessel is a standard repair that ensures your system operates safely and efficiently without pressure fluctuations.
