The first is heated by an electric boiler supplying 180°F water. The second, by an air-to-water heat pump supplying 120°F. Sterling rates the unit at 104,000 BTU\/h with 200°F entering water, 60°F entering air and a 20°F drop. But its correction factors give 0.857 in the first case and 0.429 in the second. Same model, same airflow, very different heat.\u003c\/p\u003e\n\u003cp\u003eThat is why we never choose a unit heater on its rating alone. We start from the actual water temperature of your installation, then the heat-loss calculation, and only then the size. The other published factors are 0.715 at 160°F, 0.571 at 140°F and 0.286 at 100°F.\u003c\/p\u003e\n\u003ch3\u003eWhat the HSB14411 does\u003c\/h3\u003e\n\u003cp\u003eThis horizontal unit heater from the HS series hangs from the ceiling, circulates the water from your loop through a standard header-type coil and blows 2,200 CFM of warmed air, at 1,000 FPM at the outlet. It suits winter storage buildings for boats or recreational vehicles, dealership service shops, distribution warehouses and plants with a central electric boiler, whether in \u003cstrong\u003eLaval\u003c\/strong\u003e, on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e or on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe 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. On the loop side, it takes 10.4 GPM with a 20°F drop, for a pressure drop of 0.43 ft H2O. In a lightly heated winter storage building, the loop can contain propylene glycol: Sterling publishes correction factors for that mix. The coil is rated up to 150 PSI (1,034 kPa) or 320°F (160°C) on hot water.\u003c\/p\u003e\n\u003ch3\u003eInstallation by AirGreen\u003c\/h3\u003e\n\u003cp\u003eAfter the visit and the calculation, we confirm with Sterling the weight and dimensions, which are not in the data we verified, then check the structure. Our technicians hang the unit heater 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 everything up while measuring the water 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).
