37,500-75,000 BTU Adjustable Radiant Tube Garage Heater (NG/LP)

Warm up your wrenching sessions with a garage heater that actually keeps up. The 37,500–75,000 BTU Adjustable Radiant Tube Garage Heater is a natural gas or liquid propane infrared garage heater that warms the things that matter—your tools, cars, floor, and workbench—so the whole shop feels comfortable without the blast of a fan.

Output and coverage are dialed for real-world garages: it’s designed for insulated spaces (minimum R-12 in walls and roof) and covers from 27' x 36' (972 sq. ft.) up to 40' x 40' (1,600 sq. ft.). A non‑insulated garage will use more fuel and feel cooler than an insulated garage.

• Thermostat and modulating control included.
• BTU output is a manual adjustment so you can crank it up to heat the garage fast, then turn it down once you’re comfortable.
• 20 feet long by 15 inches wide.

Why gearheads love this gas garage heater:

• Infrared radiant tube heater tech warms objects (cars, floors, walls, people) for quiet, draft-free comfort.
• Smart and efficient: uses 30%–40% less energy than many traditional heating systems and helps melt snow and ice off vehicles while keeping the garage floor warm and dry.
• Certified for indoor and outdoor use, with venting through the roof or wall for flexible installs in garages and shops.
• Slim, low-clearance profile fits tight overhead spaces; multiple units can be grouped to achieve the length you want.
• Heavy-duty build with high‑quality stainless steel workmanship and an eight‑sided reflector design that stays stable during expansion and contraction for quiet operation.
