{"product_id":"heat-exchanger-assembly-h400","title":"Hayward Heat Exchanger Assembly, H400","description":"\u003cp\u003eThe Hayward HAXHXA1403 is the heat exchanger assembly for the H400 H-Series gas heater. It is supplied as a kit that contains the parts needed to complete the replacement, and it covers the millivolt, ED1 and ED2 versions of the heater.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe design\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe exchanger uses the patented single header V baffle arrangement. That geometry moves heat into the water quickly and leaves virtually no condensation inside the cabinet, which is one of the things that shortens the life of a heater when it goes wrong. The tubing is protected with cupro nickel, the tougher of the materials Hayward specifies, for durability in harder or more aggressive water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eConfirm the heater size on the data plate. This assembly is the H400 and does not cross to the smaller models in the range. The union nuts, header o-ring set and CPVC flange nipples around the exchanger are separate part numbers, and a heater old enough to need an exchanger is usually worth refreshing those at the same time.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48626602410196,"sku":"HAY-151-1403","price":1866.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_09a775e2-a723-44c7-a4f1-a7d4e7571f8d.jpg?v=1788712938","url":"https:\/\/www.activepoolsupply.com\/products\/heat-exchanger-assembly-h400","provider":"Active Pool Supply","version":"1.0","type":"link"}
