This horizontal unit heater hangs from the ceiling, receives the hot water from your electric boiler or air-to-water heat pump and blows 1,400 CFM of warmed air, at 900 FPM at the outlet. With 200°F entering water, 60°F entering air and a 20°F drop, Sterling publishes 61,000 BTU\/h, and 54,900 BTU\/h at reduced speed (1,100 CFM).\u003c\/p\u003e\n\u003cp\u003eIt is also the first size in the series with a 1\/12 HP motor. It runs on 115 V, single phase, 60 Hz, single speed, and the manufacturer describes it as totally enclosed with thermal overload protection. It suits a municipal garage, a commercial space opening onto a delivery dock or the maintenance shop of a property portfolio.\u003c\/p\u003e\n\u003ch3\u003eOne unit or several smaller ones: how we decide\u003c\/h3\u003e\n\u003cp\u003eIn a good-sized garage or commercial space, two approaches often look equal on paper. A single HSB08411 simplifies the piping and the electrical connection. Two smaller units spread the air better in a long or cluttered room. We decide after the visit, from the floor plan and a heat-loss calculation.\u003c\/p\u003e\n\u003cp\u003eEither way, water temperature remains the starting point. Sterling publishes the factors to apply to the 200°F rating: 0.857 at 180°F, 0.715 at 160°F, 0.571 at 140°F, 0.429 at 120°F and 0.286 at 100°F. An electric boiler or air-to-water heat pump that supplies cooler water will therefore give less heat per unit, and the calculation accounts for it.\u003c\/p\u003e\n\u003cp\u003eOn the loop side, the HSB08411 needs 6.1 GPM with a 20°F drop, for a pressure drop of 0.24 ft H2O. The coil accepts hot water or a propylene glycol solution, and it is rated up to 150 PSI (1,034 kPa) on hot water.\u003c\/p\u003e\n\u003ch3\u003eWhat our installation covers\u003c\/h3\u003e\n\u003cp\u003eThe documents we verified do not list the box contents. Our quote therefore includes everything needed: hanging rods, isolation valves, air purging and control. Our technicians hang the unit level, connect it to the loop, make the 115 V electrical connection, then start it up and check the flow.\u003c\/p\u003e\n\u003cp\u003eAirGreen is a family business established in \u003cstrong\u003eMontreal\u003c\/strong\u003e for more than fifteen years, holding RBQ licence 5645-9605-01 (ventilation, refrigeration and electrical).
