Volano UP GBF - 6 Connection Mild-Steel Buffer Tank (Indoor)

Volano UP GBF 6-Connection models are compact, wall-hung buffer tanks designed for more complex hydronic and air-to-water heat pump systems. With six generously sized connections, they make it easy to manage multiple circuits, add sensors, and fine-tune system hydraulics in a small footprint.

Key features

• 6-connection layout for flexible piping
  Two connections for the heat source plus four additional tappings for system circuits, mixing sets, or sensor wells—ideal for multi-zone or future expansion.

• Wall-hung, space-saving design
  Vertical, wall-mounted tank keeps the floor clear and fits in tight mechanical rooms, closets, or utility spaces.

• Sized for real-world systems
  Models from 25–100 liters (~7–26 gallons) provide enough buffer volume to stabilize most residential and light-commercial heat pump or boiler systems.

• Improved system stability
  Adds thermal mass to reduce compressor and burner short cycling, smooth out flow in zoned systems, and support more stable operation during defrost cycles.

• Mild-steel construction with protective jacket
  Robust steel vessel with a clean, durable outer jacket for a finished appearance and easy wipe-down.

• Hydronic closed-loop use
  Designed for closed heating and cooling loops (non-potable); not intended for domestic hot water storage.

Typical applications

• Air-to-water heat pumps with multiple zones or circuits

• Hydronic systems needing extra tappings for sensors, mixing valves, or bypasses

• Retrofits where you want a buffer tank that can handle today’s design and tomorrow’s upgrades
