20,000-40,000 BTU Radiant Tube Garage Heater, Adjustable NG/LP, 10 ft

Fire up wrenching season with a garage heater that actually keeps up. This 20,000–40,000 BTU radiant tube heater is built for gearheads who want consistent, quiet heat in the garage or shop without the blast of a fan. It runs on natural gas or liquid propane (your call) and uses infrared radiant heat to warm the stuff that matters—floors, tools, cars, and you.

Dial it in the way you like it: the thermostat and modulating control are included, and the BTU output is a manual adjustment so you can crank it up for a fast warm-up and turn it down once you’re comfortable.

• Covers an area 14' x 12' or 168 sq. ft. to 24' x 26' or 624 sq. ft.
• Intended for an insulated garage with a minimum of an R-12 rating in the walls and roof. A non-insulated garage will consume more fuel and will feel cooler than an insulated garage.
• 10 feet long by 15 inches wide

Why gearheads love this radiant tube heater:

• Infrared heat warms objects, not just air, for quiet, draft-free comfort. Rooms above or next to the heated space can feel cozier, and snow and ice on vehicles melt off while the floor stays warm and dry.
• Certified for indoor and outdoor use with flexible venting through the wall or roof. Each unit comes with a thermostat and hanging kit for straightforward installation.
• Energy-smart design uses 30%–40% less energy compared to many conventional forced-air garage heaters.
• Slim profile with low clearance requirements and an architectural look that tucks up clean on the ceiling—great for tight overhead spaces or when you’re grouping multiple radiant tube heaters.
• Heavy-duty build quality: high-quality stainless steel components and an eight-sided reflector design that stays stable during expansion and contraction for quiet operation.
• Fuel options: run it as a natural gas garage heater or a propane garage heater. Easy-light, 3-Try direct spark, electronic ignition system—no standing pilot, no valves to turn, no thermocouples to replace.

Standard equipment you’ll appreciate in a serious shop heater:

• Pre-assembled and prewired burner control housing
• Industry-standard gas, electrical, and venting connections
• Balanced air rotor and thermal overload protection motor
• Visual burner inspection sight glass
• Combustion and air proving safety switch
• 3-Try spark ignitor control with 100% safety shut-off
• Low voltage thermostat connection
• 4" heat-treated aluminum combustion tube
• Aluminum reflector (largest and heaviest gauge in the industry) with anti-walk, eight-sided design
• 4" mild steel radiant heat exchanger
• Tube couplers, joint/hanger pieces, and a heat economizer baffle

If you’re after a clean, vented gas garage heater that delivers steady infrared warmth, this radiant heat tube heater is the move—perfect for a garage, workshop, or home pit space.
