Engineered for high performance, the \u003cstrong\u003eA1400-L\u003c\/strong\u003e model is specifically designed to provide reliable thermal expansion compensation in demanding residential and commercial heating circuits.\u003c\/p\u003e\u003cp\u003eThese expansion tanks utilize advanced internal bladders to interface with compressed air, effectively absorbing and releasing water volume changes as the system fluid temperature fluctuates. This process prevents pressure spikes, protects system components from stress, and significantly reduces the physical footprint of the equipment compared to traditional steel tanks.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Footprint:\u003c\/strong\u003e Designed to reduce required tank size by up to 80% over standard designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Stability:\u003c\/strong\u003e Maintains consistent system pressure by managing thermal expansion and contraction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Operation:\u003c\/strong\u003e Uses compressed air technology to handle varying water volumes seamlessly as the system cycles.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for closed-loop hydronic heating systems, radiant floor heating, and boiler applications requiring space-saving, high-efficiency expansion control.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43133424730206,"sku":"573100-014","price":11483.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/573100_014_image_c6909fc7-e25d-4be3-ae48-a11dfc0c76c8.png?v=1786105768","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-573100-014-a1400-l-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
