Why Choose EXCELSIOR WB Buffer Vessels?

EXCELSIOR WB buffer vessels are built for heating systems that require additional stored water volume and more stable operation. By helping balance system demand, the vessel can support smoother performance and reduce unnecessary strain across the wider system.

The stainless steel construction provides long-term durability across domestic, commercial and industrial environments. This makes the range suitable for projects where dependable buffer volume is needed as part of a wider heating or plant room system.

With capacities from 80 to 3000 litres, EXCELSIOR WB gives installers and specifiers a flexible buffer vessel range for different system sizes, layouts and performance requirements.
