Propane Radiant Tube Heaters

A standard 20 lb propane tank holds about 430,000 BTUs of energy. Running continuously on a 30,000 BTU heater, it would last roughly 14-15 hours; however, most heaters cycle on and off, so actual runtime is typically longer, often spanning several days of intermittent use.

Our propane radiant tube heaters span a wide BTU input range from 30,000 to 250,000 BTU/hr, with configurations for small workshops (30K-60K BTU) up to large warehouses and aircraft hangars (160K-250K BTU). Dual-stage and modulating models adjust output automatically based on ambient temperature for optimal efficiency.

Power-vented systems use a fan to push combustion gases through the tube and out an exhaust vent, suited for single-unit installations. Vacuum-fired systems draw combustion gases through the tubing using a remote exhauster, allowing multiple heaters to share one venting system — ideal for large, custom-engineered installations.

Stainless steel burner housings and radiant tubing are recommended for corrosive or high-humidity environments such as natatoriums, car wash bays, chemical processing plants, and food processing facilities. Standard powder-coated units are suitable for typical warehouses, garages, and manufacturing floors where corrosion exposure is minimal.

Propane radiant tube heaters typically deliver 30-50% energy savings over conventional forced-air heating systems. Radiant heat directly warms objects, floors, and occupants rather than heating and circulating large volumes of air, reducing heat loss through ventilation and stratification near the ceiling.

Combustion Research Corporation backs its propane radiant tube heaters with a 10-year warranty on radiant tubes against internally created corrosion, plus additional multi-year warranties on burner components, ignition controls, and electrical parts — reflecting confidence in long-term durability.
