Onsen 1.0L Accumulator Tank


The Onsen 1.0L Accumulator Tank is an ideal complement to the Onsen 3.0 Pump, helping to extend the life of the pump, decreasing power consumption, and reducing plumbing noise (pipe hammer) caused by water pressure systems.

Designed to work in conjunction with the pump, the Onsen 1.0L Accumulator Tank acts as a pressure buffer, which allows for smoother water flow and reduces on/off cycling by the pump by lessening variations in water pressure and flow between the pump and the water fixtures.

By ensuring even water flow and pressure, the Onsen 1.0L Accumulator Tank provides better control of hot water temperatures in water systems using tankless gas water heaters.
It is also a great addition to pressure water systems on boats, RVs, cottages, and other similar applications.
