Flamco - 1800 Ltr - FlexTherm PS 1800 Hot Water Storage Vessel - 3 Bar

The Flamco - 1800 Ltr - FlexTherm PS 1800 Hot Water Storage Vessel - 3 Bar is a pressure vessel designed to support pressure stability within the system and reduce rapid cycling.

With pressure duties up to 3 Bar, it is built to help protect connected equipment and smooth system operation.

Purpose-built for heat pump systems and sealed heating circuits, the Flextherm PS Thermal Storage Buffer stores heated water to stabilise flow, smooth demand and cut compressor cycling.

Floor-standing steel construction with 90° opposed connections allows corner placement for a smaller footprint. Models up to 2000 Ltrs include height-adjustable feet for accurate levelling. Four G½" temperature sensor ports support precise control. Maximum operating temperature 95 °C.

• Heat-pump friendly: reduces start/stop frequency
• Compact install: 90° connections suit corner mounting
• Scalable: link multiple buffers for higher volume
• Serviceable: adjustable feet (≤ 2000 Ltrs) for easy levelling

Note: this PS variant is typically used for heating; for chilled applications with factory insulation specify Flextherm PSK.
