Volano UP WBF — Polywarm® 4 Connection Buffer Tank (Indoor)

Volano UP WBF is a wall-hung thermal buffer and hydraulic separator for air-to-water heat pumps and hydronic systems. Built in mild steel with an internal Polywarm® coating and rigid polyurethane insulation, it’s designed to stabilize hot and chilled water systems while protecting the tank and keeping system water clean. Key features Thermal buffer + hydraulic separatorProvides both functions in one compact unit: added thermal mass to reduce heat-pump cycling, and hydraulic separation to decouple heat-pump flow from distribution flow for smoother operation. Polywarm® internal finishCarbon-steel vessel with a Polywarm® internal coating for improved corrosion protection and “clean system” operation in modern hydronic circuits. High-performance insulationRigid polyurethane foam insulation minimizes standby losses for both hot and chilled water operation.
