Built with a heavy-duty 316L stainless steel tank and high-output internal coil design, this unit provides exceptional durability and outstanding resistance to demanding, aggressive water environments. Its low-maintenance, high-performance architecture eliminates the need for a sacrificial anode rod, making it an ideal solution for residential and light commercial hydronic heating loops.\n  \u003c\/p\u003e\n  \u003cp style=\"margin-top: 15px;\"\u003e\n    Operating seamlessly as an independent zone connected directly to your primary heating boiler, the Aqua Plus 45 generates ultra-fast recovery times and continuous hot water delivery by utilizing a tightly wound 1-inch diameter heat exchanger coil. The tank features a high-density, 2-inch thick CFC-free foam insulation jacket that reduces standby heat losses down to an exceptional 0.4°F per hour, maximizing overall fuel conservation. Encased in a resilient, dent-resistant pewter gray polymer resin outer shell, this indirect water heater provides long-lasting mechanical protection and reliable domestic thermal staging.\n  \u003c\/p\u003e\n\n  \u003c!-- Advanced Engineering Features Bullets --\u003e\n  \u003cdiv style=\"margin-top: 25px; margin-bottom: 20px;\"\u003e\n    \u003ch4 style=\"font-size: 16px; font-weight: bold; margin-bottom: 10px; color: #111111; border-bottom: 2px solid #111111; padding-bottom: 5px;\"\u003eAdvanced Engineering Features:\u003c\/h4\u003e\n    \u003cul style=\"margin: 0; padding-left: 20px; font-size: 14px; color: #333333; line-height: 1.6;\"\u003e\n      \u003cli style=\"margin-bottom: 8px;\"\u003e\n\u003cstrong\u003ePremium 316L Stainless Steel Architecture:\u003c\/strong\u003e Advanced plasma and TIG-welded tank geometry provides total corrosion defense across harsh water applications without sacrificial rods.\u003c\/li\u003e\n      \u003cli style=\"margin-bottom: 8px;\"\u003e\n\u003cstrong\u003eHigh-Output 1\" Internal Coil:\u003c\/strong\u003e Generates excellent first-hour flow delivery with a remarkably low pressure drop on the boiler-side distribution loop.\u003c\/li\u003e\n      \u003cli style=\"margin-bottom: 8px;\"\u003e\n\u003cstrong\u003eIntegrated Digital Thermostat:\u003c\/strong\u003e Features a factory-installed precision immersion sensor probe for simple, rapid low-voltage control panel wiring.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Weil-McLain","offers":[{"title":"Default Title","offer_id":42910017781854,"sku":"633500001","price":2200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Weil-McLain_Aqua_Plus_45_vertical_indirect-fired_stainless_steel_domestic_water_heater_tank_in_pewter_gray..jpg?v=1782004393","url":"https:\/\/nationalboilersupply.com\/products\/weil-mclain-633500001","provider":"National Boiler Supply","version":"1.0","type":"link"}
