It extracts heat energy from hot water and uses the air handler's blower to distribute warm air through the conditioned space. The unit mounts directly over the air handler's discharge or return opening and supports both horizontal and vertical installations. Its heavy-duty aluminum cabinet features a baked enamel finish and full rigid foam insulation for durable, efficient operation. Licensed HVAC technicians typically install this unit as a furnace or heat pump alternative in hydronic heating applications.\u003c\/p\u003e\n\u003cp\u003eThe hhu-am-3 is suited for residential space heating systems where a hot water source such as a gas-fired water heater or boiler is already present or planned. It is sized for use with 4 to 5 ton air handlers. The unit accommodates discharge-side or return-side air handler configurations, giving installers flexibility in system layout. Heat output is adjustable to match the load requirements of the conditioned space. Optional circulation pump packages are available in 230-volt or 115-volt configurations to simplify integration with existing air handler wiring and controls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMounts directly onto the air handler discharge or return in horizontal or vertical orientation\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty rust-proof aluminum cabinet with baked enamel finish\u003c\/li\u003e\n  \u003cli\u003eFully insulated with high-R rigid foam to minimize heat loss\u003c\/li\u003e\n  \u003cli\u003eCompatible with any hot water source providing sufficient BTUH output\u003c\/li\u003e\n  \u003cli\u003eOptional 230-volt or 115-volt circulation pump for direct integration with air handler controls\u003c\/li\u003e\n  \u003cli\u003eOptional water-lubricated, low-wattage circulation pump requires no routine maintenance\u003c\/li\u003e\n  \u003cli\u003eDesign Certified and Listed to UL and CSA Standards; tested to comply with ANSI\/NSF 61-2012\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4 to 5 ton air handlers in residential hydronic heating applications.

Shut off the hot water source and de-energize the air handler before mounting or making water connections. Ensure all water connections are properly sealed and that the system is bled of air before startup. Optional ball valve and swing check valve kits should be installed per the manufacturer instructions to protect the coil and maintain flow control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential hydronic space heating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Air Handler Size\u003c\/strong\u003e: 4-5 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCabinet Material\u003c\/strong\u003e: Rust-proof aluminum with baked enamel finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation\u003c\/strong\u003e: High-R rigid foam\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Horizontal or vertical, discharge-side or return-side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptional Pump Voltage\u003c\/strong\u003e: 230-volt or 115-volt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed, CSA Certified, ANSI\/NSF 61-2012 Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AQUECOIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: hhu-am-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AQUECOIL","offers":[{"title":"Default Title","offer_id":51467555045682,"sku":"HHU-AM-3","price":954.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946506.jpg?v=1783906747","url":"https:\/\/voomisupply.com\/products\/aquecoil-hhu-am-3-hydronic-heating-unit-4-5-ton","provider":"Voomi Supply","version":"1.0","type":"link"}
