Heater for Greenhouse Solutions Guide

For commercial and agricultural greenhouses, infrared radiant heaters are often a strong choice because they warm plants, benches, floors, and workers directly instead of heating only the air near the roof. Gas-fired radiant tube heaters can support larger structures, while compact tube or electric infrared systems may suit smaller or fuel-limited spaces.

Safe greenhouse heaters should be properly sized, correctly installed, and certified to recognized standards. Combustion Research Corporation systems are CSA International Design Certified to ANSI/CGA Standards and include safety features such as direct spark ignition, safety lockout, electronic flame monitoring, and pre-purge cycles on applicable gas-fired models.

Infrared heaters warm surfaces directly, which can help maintain more stable comfort around crops, benches, and work aisles. Because radiant heat does not rely on moving large volumes of air, it can also reduce dust circulation and help avoid wasting heat in tall greenhouse roof spaces.

Greenhouse heater sizing depends on square footage, ceiling height, insulation, glazing type, outside design temperature, fuel type, and crop temperature requirements. CRC systems are quoted and engineered around these factors, with BTU ranges from compact 40,000–60,000 BTU units to large custom radiant systems for extensive agricultural facilities.

Many CRC heaters operate on natural gas or LP/propane, including Reflect-O-Ray, Omega II, Synergy, and Serengeti-IR models. Electric infrared options such as Solaira Alpha may be considered where gas or propane is impractical, though CRC typically recommends evaluating gas-fired radiant systems first when fuel is available.

Radiant infrared systems can reduce operational costs by 30–50% compared with conventional forced-air heating in many commercial applications. They deliver heat to occupied and productive zones rather than warming unused overhead air, which is especially useful in taller greenhouses or structures with frequent ventilation and air exchange.

Yes. CRC manufactures compact Serengeti-IR radiant tube heaters in 40,000–60,000 BTU packages that are suited to smaller commercial and agricultural footprints. For spot or zone heating, Synergy high-intensity ceramic infrared units can provide fast heat in protected environments where instant-on comfort is needed.
