Expansion vessel 2l DHW neutral De Dietrich 7715660

The expansion vessel 2l DHW neutral is designed to accommodate thermal expansion in domestic hot water systems. With a 2-liter capacity, it helps maintain stable pressure and prevents damage to pipes and fixtures. This neutral vessel is specifically intended for DHW circuits, ensuring that pressure fluctuations are safely absorbed. When your existing expansion vessel loses its charge or develops a leak, replacing it with this model protects your water heating system from overpressure and extends its lifespan. Ideal for combi boilers and indirect water heaters.
