Panasonic 50L Buffer Tank

The Panasonic PAW-BTANK50L-2 50 Litre Buffer Tank is engineered to work seamlessly with all Panasonic Aquarea air-to-water heat pump systems. A buffer tank helps stabilise system flow rates, protects the heat pump from short cycling and ensures efficient and reliable operation in both heating and cooling modes.

This high-quality buffer tank features Class B insulation to minimise heat loss (only 35 W), keeping system efficiency high. The tank also includes a built-in sensor pocket, allowing easy installation of temperature probes for accurate system management.

Integrated components—such as the automatic air vent and drain cock—simplify maintenance and ensure long-term reliability.
