The Sterling HSB15611 releases its air at 1,150 FPM, the highest velocity Sterling publishes in the HS series, at an airflow of 2,600 CFM. The faster the air leaves, the farther the jet carries before mixing with the room air.\u003c\/p\u003e\n\u003cp\u003eThe exact throw and mounting height, however, are not in the data we verified. We therefore position the unit with Sterling’s installation manual, taking aisles, racking and doors into account.\u003c\/p\u003e\n\u003ch3\u003eOutput, water and electrical\u003c\/h3\u003e\n\u003cp\u003eSterling rates the HSB15611 at 113,000 BTU\/h with 200°F entering water, 60°F entering air and a 20°F drop. As with any hot-water unit heater, this value drops if the water is cooler: 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, according to the manufacturer’s factors. Whether your building is heated by an electric boiler or an air-to-water heat pump, we do the calculation with the actual temperature.\u003c\/p\u003e\n\u003cp\u003eThe circuit must supply 11.3 GPM with a 20°F drop, for a pressure drop of 0.53 ft H2O. The loop can contain water or a propylene glycol solution, for which Sterling publishes correction factors. The 1\/3 HP motor is single speed and connects on 115 V, single phase, 60 Hz. The coil is rated up to 150 PSI (1,034 kPa) or 320°F (160°C) on hot water.\u003c\/p\u003e\n\u003cp\u003eA word on the neighbouring size: in Sterling’s table, the HSB18011 has a higher rating at 200°F, but lower airflow and outlet velocity. In a deep building, we compare the two before recommending one or the other.\u003c\/p\u003e\n\u003ch3\u003eInstallation by AirGreen\u003c\/h3\u003e\n\u003cp\u003eOur technicians confirm the weight and dimensions with Sterling, check the structure, then hang the unit heater by rods from the connections provided, level. They connect it to the loop with isolation valves and air purging, make the 115 V electrical connection, install the control and start up the unit.\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).
