Volano UP WBF — Polywarm® 6 Connection Buffer Tank (Indoor)

Volano UP WBF 6-Connection models are indoor Polywarm® buffer tanks and hydraulic separators designed for more complex hydronic and air-to-water heat pump systems. With six generously sized connections, they make it easy to connect primary and secondary circuits, add mixing sets, or install sensors while keeping everything in a compact, wall-hung package. Built from mild steel with an internal Polywarm® coating, rigid polyurethane insulation, and a grey soft PVC outer cover, these tanks are made for clean, efficient operation on closed hot and chilled water loops. The added buffer volume reduces heat-pump short cycling, while the hydraulic separation helps decouple heat-pump flow from distribution flow for smoother system performance. Volano UP WBF 6-Connection is ideal when you want the benefits of a buffer tank and hydraulic separator in one unit—and you know you’ll need extra tappings for zones, sensors, or future expansion.
