Ausdehnungsgefäß „7l“ von De Dietrich 7769760

The expansion vessel 7l is a key component in sealed heating systems, accommodating the expansion of water as it heats up. With a 7-liter capacity, it is suitable for smaller boilers and heating setups, helping to maintain stable pressure and prevent damage. This vessel is typically pre-charged with air and features a diaphragm that separates water from the air chamber. When replacing an old or faulty expansion vessel, choosing the correct size is critical for system performance. As a boiler spare part, it ensures your heating equipment operates safely and efficiently, reducing the risk of pressure-related issues.
