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.\n\nThis 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.\n\nConstructed 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.\u003c\/p\u003e","brand":"Flamco","offers":[{"title":"Default Title","offer_id":57270016934272,"sku":"1200197","price":32.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/0629\/4936\/files\/ca7bea45-e51f-43e3-9071-6858f05d9002.jpg?v=1785167340","url":"https:\/\/www.lavastore.co.uk\/products\/baseflex-heating-expansion-vessel-12l-1-5-bar-pre-charge-3-4-connection","provider":"LavaStore","version":"1.0","type":"link"}
