Expansion vessel 10 L De Dietrich 7769943

The expansion vessel 10 L is a key component in sealed heating systems, absorbing excess water pressure as it expands when heated. This 10-liter capacity vessel helps maintain stable system pressure, protecting pipes, radiators, and the boiler from overpressure damage. If you notice frequent pressure drops or the safety valve releasing water, a faulty expansion vessel may need replacement. Suitable for many boiler spare parts applications, this vessel is pre-charged with nitrogen and ready to install. Proper sizing is crucial, and a 10 L vessel is common for domestic heating systems. Ensure compatibility with your system's requirements.
