Compact 40K-60K BTU power-vented radiant tube heaters for smaller workshops, single service bays, pole barns, detail bays, and light commercial spaces.

Synergy Infrared

High-intensity ceramic infrared heaters for instant-on spot or zone heat at workstations, loading areas, protected outdoor spaces, and shop entrances.

Sizing & ROI

Engineering guidance for BTU sizing, mounting height, clearances, installation cost, operating cost, payback period, and utility rebate evaluation.

System Comparison

Side-by-side guidance comparing radiant tube, forced air, high-intensity ceramic, vacuum-vented, power-vented, gas-fired, and electric infrared heating options.

A Practical Shop Heater Selection Process

Measure the Shop Conditions

Start with the shop’s square footage, ceiling height, insulation level, door sizes, and how often overhead doors open. These details determine whether a compact, power-vented, vacuum, or spot-zone infrared system is the best fit.

Proven Applications

Radiant infrared systems are specified for shops, warehouses, service bays, hangars, arenas, and industrial plants.

"Our 16-bay garage runs with doors opening constantly, so keeping students comfortable through Connecticut winters was a real challenge. Reflect-O-Ray units installed over each bay solved it. The concrete floor acts as a heat sink, absorbing and re-radiating warmth back into the space, so students feel warm at lower thermostat..."

Ella T. Grasso Technical School

"We chose a two-stage Omega II 30-ft low intensity tube system for our new two-story hospital, and it's been the right call. The 60,000–100,000 MBH output keeps our rear operating area genuinely comfortable, not just warm air blowing around. Our concrete slab absorbs and re-radiates the heat, so the space..."

Fenton River Veterinary Hospital

"Hangars are the hardest buildings to heat. High bay, minimal insulation, and a massive overhead door that dumps cold air in every time it opens. Forced air simply couldn't keep up without burning through energy. Ten 40-foot straight tubes at 150 MBH with reflectors changed that completely. Radiant heat warms..."

Tac Air – Bradley International Airport

"Heating a 120-yard indoor field under a 65-foot domed roof is not a standard job, and Reflect-O-Ray was the only system engineers felt could be tailored to it. Twelve 360,000 B/H burners firing 140-foot tubes condition the entire space efficiently. Infrared fit directly into our campus energy conservation standards and..."

Frequently Asked Questions

How many BTUs to heat a 40x60 shop?

A 40x60 shop is 2,400 square feet. As a rule of thumb, an insulated low-bay shop may need about 25-40 BTU per square foot, or 60,000-96,000 BTU/hr. High-bay, poorly insulated, or frequently opened shops may require 40-65+ BTU per square foot, or 96,000-156,000+ BTU/hr. Final sizing should account for ceiling height, doors, insulation, and climate.
