It uses a copper tube heat exchanger and moves 580 CFM through a fan-guarded assembly driven by a 61-watt, 120-volt totally enclosed motor with a built-in thermal overload protector. Connections are 1-1\/4 inch FPT on both inlet and outlet. Maximum allowable working pressure is 150 psi. The unit ships at 47 pounds. It is installed by licensed HVAC or mechanical contractors in commercial and industrial heating applications where hot water or steam distribution is already in place.\u003c\/p\u003e\u003cp\u003eThis unit heater is designed for horizontal mounting in warehouses, garages, loading docks, workshops, and similar spaces where overhead or wall-mounted forced-air heating from a hydronic or steam boiler system is required. The horizontal airflow pattern distributes heat across floor-level work areas. At 61,000 BTU\/h and 580 CFM, it suits mid-size commercial or industrial spaces. The totally enclosed motor is appropriate for dusty or moderately demanding environments typical of these installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e61,000 BTU\/h output rated at 200 degrees F water temperature\u003c\/li\u003e\n\u003cli\u003eCopper tube heat exchanger for efficient heat transfer and corrosion resistance\u003c\/li\u003e\n\u003cli\u003e580 CFM fan-guarded airflow in horizontal discharge configuration\u003c\/li\u003e\n\u003cli\u003e61-watt, 120-volt totally enclosed motor with thermal overload protection\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch FPT inlet and outlet connections for direct piping to hydronic or steam supply\u003c\/li\u003e\n\u003cli\u003e150 psi maximum working pressure rating suitable for most commercial boiler systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application unit heater for horizontal hydronic or steam heating systems operating within 150 psi maximum working pressure and supplying 120-volt power to the fan motor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC or mechanical contractor in accordance with local mechanical codes and IFGC or applicable boiler and pressure vessel regulations. Shut off and depressurize the hydronic or steam supply line and disconnect electrical power before connecting or servicing the unit. Pipe connections should be made with appropriate thread sealant rated for steam or hot water service. Do not exceed the 150 psi maximum working pressure rating of the unit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating Capacity\u003c\/strong\u003e: 61,000 BTU\/h at 200 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow\u003c\/strong\u003e: 580 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Power\u003c\/strong\u003e: 61 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Horsepower\u003c\/strong\u003e: 1\/4 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Electric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Enclosure\u003c\/strong\u003e: Totally Enclosed with Thermal Overload Protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Material\u003c\/strong\u003e: Copper Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet\/Outlet Connection\u003c\/strong\u003e: 1-1\/4 inch FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Weight\u003c\/strong\u003e: 47 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MESTEK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: hsb08411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MESTEK","offers":[{"title":"Default Title","offer_id":51233712210226,"sku":"HSB08411","price":1060.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629349.jpg?v=1780107430","url":"https:\/\/voomisupply.com\/products\/mestek-hsb08411-hydronic-steam-unit-heater-61000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
