That is not a suggestion: the heaters changed, and a bundle from the wrong era will not go in correctly. Read the manufacture date on the rating plate before ordering, and confirm you have the ASME version rather than the non ASME build.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the tube bundle does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt is the part that actually transfers heat. Pool water runs through the copper tubes while combustion gas passes around them, and everything else in the heater exists to support that exchange. When the bundle leaks, scales heavily or corrodes through, the heater is out of service until it is replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy bundles fail\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater chemistry, almost always. Low pH eats copper from the inside, and high calcium plates the tubes so heat cannot get through and the metal overheats. Getting chemistry under control before the new bundle goes in is what determines whether it lasts.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48626309234900,"sku":"RAY-151-1459","price":893.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_5035a27b-f384-4829-93fd-2376c1212b20.png?v=1788708013","url":"https:\/\/www.activepoolsupply.com\/products\/tube-bundle-copper-asme-206a","provider":"Active Pool Supply","version":"1.0","type":"link"}
