Panasonic 200L Pre-Plumbed Cylinder with 70L Buffer Tank

The Panasonic 200L Pre-Plumbed Cylinder with Integrated 70L Buffer is a complete hot water and hydraulic solution built for Panasonic Aquarea heat pump systems. The Duo design places the 70L buffer tank above the 200L unvented domestic hot water cylinder, reducing cycling of the heat pump and improving long-term compressor life.

Built in the UK and pre-assembled for rapid installation, this unit significantly reduces labour time and the number of required system components. The cylinder features a high-efficiency multi-pass corrugated stainless steel heat exchanger, optimised for heat pump flow temperatures, ensuring fast and efficient hot water recovery.
