Accumulator system for Nano-PK

Hybrid accumulator tank
HWS 320 / FWS / FWS-Z

This Hargassner hybrid accumulator tank is distinguished by its perfect size.

It was specifically designed for use in combination with the Nano-PK 6–15 kW and Nano-PK 20–32 kW pellet boiler. It impresses with its perfectly tailored appearance, the small amount of space it occupies and its short installation time.

Thanks to the hydraulic connection set, it can be installed and commissioned very quickly. It is available both as a simple expansion tank and as a heat storage tank with a fresh-water station with or without a hot water circulation  pump.
