Hydronic means it heats with hot water circulated from a boiler or water heater through its coil rather than with a furnace burner or electric strip — a house with a boiler gets forced-air heating and central air from one cabinet. It ships A\/C ready with the A-coil and a factory-installed TXV, so adding an R-454B condensing unit makes it a complete cooling system. Freeze protection works in both heating and cooling.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e3.5 to 4 ton blower drive range\u003c\/li\u003e\n\u003cli\u003eHydronic heating — hot water from a boiler or water heater, no burner or heat strip\u003c\/li\u003e\n\u003cli\u003eA\/C ready with A-coil and factory-installed TXV\u003c\/li\u003e\n\u003cli\u003eRuns on standard 115V power\u003c\/li\u003e\n\u003cli\u003eECM constant-torque motor — holds airflow against duct static\u003c\/li\u003e\n\u003cli\u003eMotor speed and torque controlled by software embedded in the motor\u003c\/li\u003e\n\u003cli\u003eFreeze protection in both heating and cooling\u003c\/li\u003e\n\u003cli\u003eMulti-position design\u003c\/li\u003e\n\u003cli\u003eCopper tube \/ aluminum fin coil\u003c\/li\u003e\n\u003cli\u003eR-454B compatible for the cooling circuit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COMFORT-AIRE","offers":[{"title":"Default Title","offer_id":58363986805039,"sku":"HWCR47X0A","price":3090.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0826\/4436\/9711\/files\/HWCG-X_8ed474de-df72-43ec-881d-0770900482cb.png?v=1787595149","url":"https:\/\/www.varouj.com\/products\/comfort-aire-3-5-4-ton-hydronic-air-handler-ecm-constant-torque-with-factory-txv-115v-r-454b-hwcr47x0a","provider":"Varouj.com","version":"1.0","type":"link"}
