Infratech Comfort 42.5" Slimline 2400 Watts Single Element Heater 240V
The Infratech SL-2424 is a 42-1/2" 2,400-watt electric infrared heater with a single quartz element. It warms people, tables and floors directly instead of heating the air, so the warmth holds up on a breezy patio. Model number SL-2424.
It runs on 240 volts at 10 amps, and Infratech rates it to cover about 7' x 7' at a mounting height of 7' to 9'. It suits a covered patio, a pergola, an outdoor kitchen or a restaurant terrace.
The Infratech SL-2424: A Slim Infrared Heater for Covered Outdoor Spaces
Infratech's medium-wave quartz elements give off a soft, barely visible glow rather than the harsh glare of short-wave or halogen heaters. Because infrared warms solid objects instead of the air, a breeze does not carry the heat away, and there is no gas line, flame or fan.
The Slimline has a narrow profile that tucks under an eave, a pergola beam or a porch ceiling. It comes in silver or black, and the black version disappears against a dark ceiling. Compare it with our other electric patio heaters, or see all Infratech heaters and controls.
A licensed electrician must hardwire the heater; the junction box takes standard 1/2" conduit fittings. It comes with T-slot brackets for wall or ceiling mounting, with positive stops at 30 and 45 degrees. On a wall, Infratech recommends angling it 30 to 60 degrees down, about 45 degrees being best.

FAQs
How much area will it heat?
Infratech rates it to cover about 7' x 7' at a mounting height of 7' to 9'. Indoor or well-protected spaces usually do better than that, and very cold or windy conditions do worse.
What does it cost to run?
Multiply your utility's rate per kilowatt-hour by 2.4, the heater's wattage in kilowatts. That gives the cost for each hour at full power.
Which control should I choose?
An on/off switch is the simplest choice. A contactor panel with timer adds a timer and smart switch, and the Universal Control Panel adds dimming, zoning and app control. Choose the control before the wiring goes in.

Warranty
Infratech's limited warranty covers manufacturer replacement parts for the original purchaser at the original installation site. It does not cover labor, and Infratech asks you to register the heater to activate the warranty. Using controls or accessories from other brands with Infratech heaters may void it. The full terms are in the Infratech manual linked above.
