LavaTap - Baseflex Heating Expansion Vessel 1.5 Bar - 18 L Capacity (3/4 Inch Connection) for Central Heating and Cooling Pressure Management

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 integ
