46000 BTU Stainless Steel Commercial Patio Heater

With proper installation and maintenance, a commercial-grade 46,000 BTU patio heater built with stainless steel construction can last 10 or more years. Combustion Research Corporation backs their radiant tube heaters with a 10-year warranty on internally created corrosion. The corrosion-resistant aluminized steel tubing and stainless steel burner components are specifically engineered for long service life in outdoor environments.

A 46,000 to 48,000 BTU commercial patio heater can typically cover an area of approximately 200 to 400 square feet, depending on ceiling height, ambient temperature, wind exposure, and insulation. For ceiling-mounted infrared radiant heaters, coverage is more direct and efficient compared to forced-air systems, as heat is delivered to people and surfaces rather than warming air that can dissipate quickly outdoors.

Combustion Research Corporation's commercial patio heaters are available for both Natural Gas (NG) and Propane Gas (LP) fuel types. Models such as the Synergy Patio Heater and Serengeti-IR series support either fuel option, giving commercial operators flexibility depending on available utility connections or on-site propane storage. Consult your representative to confirm the correct orifice and pressure settings for your fuel type.

Select models, including the Synergy Patio Heater series, require no direct venting and can be used in protected outdoor environments with fewer roof penetrations. Other power-vented models like the Omega II PEP and Serengeti-IR series use power-vented or vacuum-fired systems. The right choice depends on your specific installation environment — indoor patios, covered walkways, or semi-enclosed spaces have different ventilation requirements.
