Detroit Radiant ELX 24 Inch Heater: a compact electric heater for a seat or doorway
The Detroit Radiant ELX 24 Inch Heater is the smallest ELX, an electric patio heater 24 inches long. It suits a single seat or doorway. Quartz heating elements sit in black powder coated steel or brushed stainless steel. For homes, it goes outdoors, not inside a room. Adjustable ceiling brackets are included; wall brackets are optional. Detroit Radiant Products is a family owned company founded in 1955 that builds its heaters in Warren, Michigan.
Radiant heat warms people and surfaces directly, like sunshine, instead of warming the air, so it works outdoors. Choose one, two, or three elements in the same housing. High output elements give 1,360 watts each, up to 4,080 watts. Standard elements give 750 watts each with a softer orange glow. Pick either type on this page. Minimum mounting heights are 6, 7.5, or 9 feet for one, two, or three elements. An electrician wires it to the voltage you pick on the page; it is not a plug in heater. All components have a one year warranty. Need more length? See the Detroit Radiant ELX 33 Inch Heater. The Detroit Radiant ELX 24 Inch Heater ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
How many elements should I choose?
The Elements selector sets single, dual or triple lamps, with the price shown per option. The Specifications tab gives 1,360 to 4,080 watts across those counts for the 24 inch ELXT, and the clearance sheet raises the minimum mounting height from 6 feet for a single to 7.5 for a double and 9 feet for a triple.
What voltages?
Single and dual element units offer 120, 208, 240, 277 or 480 volts; the triple offers 208 to 480, per the Voltage selectors. Because wattage tracks voltage, the brochure advises matching the supply available at the mounting point before choosing chassis and element.
What clearances apply?
At 0 degrees the clearance sheet lists 16 inches front and behind, 12 inches at the ends, 6 above and 56 below for a single element; 28, 28, 26 and 86 for a double; 31, 31, 34 and 105 for a triple. Angled installs up to 45 degrees use the larger of the two sets; recessed mounts must keep the same distances.
Are the elements interchangeable?
Yes, the brochure describes interchangeable lamps: medium wave, high-output medium wave, clear short wave and ruby short wave. This listing ships with ELXT high-output or ELXM standard medium wave per the Element Type selector; the ELXT gives short wave heat with about 30 percent less brightness.
What mounting hardware comes with it?
0 to 45 degree adjustable brackets are included per the brochure. Stainless wall mounting brackets, a 24 inch wire guard sized to the element count and 24 inch recessed mount kits for single or dual units are on the Accessories selectors. Finish is black or brushed stainless, priced on the Finish selector.
Indoor or outdoor?
UL listed for indoor and outdoor commercial and outdoor residential use per the Specifications tab and brochure, with a 1 year warranty on all components. Compare it with our other wall mounted patio heaters before choosing a length.
