It hangs from the ceiling, receives the hot water from your system and runs it through a standard header-type coil. A propeller fan pushes 1,100 CFM of air across it, which leaves at 800 FPM through horizontal louvers that come standard. This stronger jet helps the warm air come down to the work area.\u003c\/p\u003e\n\u003cp\u003eThe manufacturer’s rating is 52,300 BTU\/h, measured with 200°F entering water, 60°F entering air and a 20°F drop. At reduced speed, Sterling publishes 47,000 BTU\/h at 950 CFM. The 1\/20 HP motor runs on 115 V; it is single speed, totally enclosed with thermal overload protection.\u003c\/p\u003e\n\u003ch3\u003eWhich buildings we propose it for\u003c\/h3\u003e\n\u003cp\u003eWe consider it for a light production shop, a farm machinery building on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e or the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e, or the garage of a fleet of service vans. What they share: a work space, often tall, already served by an electric boiler or an air-to-water heat pump, where the floor has to stay clear.\u003c\/p\u003e\n\u003ch3\u003eWhat we calculate before recommending it\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eActual output.\u003c\/strong\u003e Sterling publishes factors by water temperature: 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.
