Baseflex Heating Expansion Vessel 12L – 1.5 Bar Pre-Charge (3/4" Connection)

Product description

The Baseflex heating expansion vessel is an essential component for maintaining the health and efficiency of your sealed heating or cooling system. As water within a closed-loop system is heated, it naturally expands. Without a dedicated expansion vessel to accommodate this increased volume, the resulting pressure spikes can lead to system fatigue, leaks, or the unnecessary activation of safety relief valves. This high-quality heating expansion vessel is engineered to act as a buffer, containing a flexible EPDM diaphragm that separates the system water from a pressurized air cushion. By absorbing the expanded water volume, the Baseflex helps stabilize internal pressure, protecting your boiler, pumps, and pipework from the stresses of thermal expansion. Constructed with a durable carbon steel shell and finished with a resilient coating, this vessel is designed for longevity in demanding plumbing environments. Each unit comes factory-set with a 1.5 bar pre-charge, making it ready for integration into standard sealed systems. Whether you are installing a new heating expansion vessel or replacing an existing unit, the Baseflex range offers a reliable, space-saving solution for both residential and commercial applications.
