These top-of-the-line radiant heaters are widely used in commercial settings such as restaurant patios and sports stadiums because of their remarkable heat-transfer efficiency – 92% of their energy input is converted into heat output. The HeLeN short-wave infrared element emits waves of radiant heat (like the sun) to directly warm people and objects in its field of coverage, rather than the ambient air. Because the element reaches its peak output within seconds, you can feel it start to warm you almost the instant you turn it on.
The 15-1/2" x 8-3/4" standard model heats an approximate 10' x 10' area; because the reflector is larger, it has a bonded gold coating to help reduce glare. It weighs about 7-1/2 lb and has a two-arm tilt-adjustable mount. The 15-1/2" x 4" low-profile model heats an approximate 8' x 10' area. It weighs just over 5 lb and is supported by a one-arm adjustable mount that pivots vertically as well as horizontally to let you aim the heat where needed.
Suitable for indoor and outdoor use, each heater has a robust, water-resistant steel and aluminum housing (IP24 rating) with a durable powder-coated finish. The polished aluminum parabolic reflector will not warp, crack or tarnish in use. Each model has a 16' grounded cord and produces 5118 BTU/hour, operating at 120 volts, 1500 watts. Silent, odorless and efficient, they operate with a cost of about 15¢ an hour based on 10¢ per kWh. The replaceable element is rated for 5000 hours. CSA/UL certified.
