Commercial & Industrial Water Heaters

EXCELSIOR WI water heaters are designed for commercial and industrial hot water systems where larger storage capacity, durable construction and reliable performance are required. Manufactured from stainless steel, the range provides dependable hot water storage for higher-demand applications.

Available from 400 to 3000 litres, EXCELSIOR WI vessels are suited to larger buildings, plant rooms and industrial systems where a standard domestic cylinder would not provide sufficient storage volume. The range gives installers and specifiers a practical stainless steel solution for projects with greater hot water requirements.
