This horizontal unit heater hangs from the ceiling, runs the water from your loop through a standard header-type coil and blows 2,200 CFM of warmed air, at 800 FPM at the outlet, through horizontal louvers that come standard. With 200°F entering water, 60°F entering air and a 20°F drop, Sterling rates it at 118,000 BTU\/h.\u003c\/p\u003e\n\u003cp\u003eIts 1\/3 HP motor is single speed and runs on 115 V, single phase, 60 Hz. Sterling does not publish a reduced-speed rating for this model.\u003c\/p\u003e\n\u003ch3\u003eHow it compares with the HSB15611\u003c\/h3\u003e\n\u003cp\u003eThe HSB18011 has a particularity worth knowing. In Sterling’s table, it has a higher rating than the HSB15611, the previous size, but lower airflow and a lower outlet velocity. These values are printed the same way in the manufacturer’s catalogue and installation manual. In practice, the HSB18011 sends more heat with less air, and that air leaves more slowly. In a wide, open space, it can be a good choice; in a deep building, the HSB15611 may suit better. We compare the two at your water temperature before recommending one or the other.\u003c\/p\u003e\n\u003ch3\u003eWhich spaces, and with what water\u003c\/h3\u003e\n\u003cp\u003eGarage with several service bays, covered eco-centre or sorting centre, fabrication shop: the HSB18011 targets wide work spaces heated by an electric boiler or an air-to-water heat pump. Water temperature remains the deciding factor. 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.\u003c\/p\u003e\n\u003cp\u003eThe circuit must supply 11.8 GPM with a 20°F drop, for a pressure drop of 0.60 ft H2O. The loop can contain propylene glycol, with the correction factors Sterling publishes. The coil is rated up to 150 PSI (1,034 kPa) or 320°F (160°C) on hot water.\u003c\/p\u003e\n\u003ch3\u003eWhat our installation covers\u003c\/h3\u003e\n\u003cp\u003eWe first confirm with Sterling the weight, dimensions and connections, which are missing from the data we verified. Our technicians check the structure, hang the unit by rods, level, connect it to the loop with isolation valves and air purging, make the 115 V electrical connection and the control, then start it up.\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).
