Natural Gas Patio Heaters — Space & Stand Up Models

Commercial-grade infrared heaters designed for outdoor use, such as the Synergy series, are entirely safe when installed correctly in protected outdoor environments. All Combustion Research outdoor heaters are CSA International Design Certified to ANSI/CGA Standards, factory pre-wired, pre-piped, and tested, and include 100% safety lockout ignition systems to ensure reliable, code-compliant operation.

It depends on the heater type. Combustion Research's Synergy ceramic patio heaters require no direct venting, making them ideal for protected outdoor spaces with fewer roof penetrations. The Omega II and Reflect-O-Ray tube heater series use either power vented or vacuum fired venting systems, which exhaust combustion gases safely to the exterior and are required for enclosed or semi-enclosed spaces.

Combustion Research offers natural gas patio and space heaters ranging from 30,000 BTU up to 250,000 BTU across the Synergy and Omega II product families. The Synergy series covers 30K–200K BTU in single and dual stage configurations, while Omega II pre-engineered packages range from 40K to 200K BTU, allowing precise sizing for small covered patios to large commercial outdoor venues.

Yes. The Synergy series is explicitly designed for use in protected outdoor environments such as covered restaurant dining decks, hotel terraces, auto dealership canopies, and commercial event venues. Units requiring no direct venting are suited to semi-outdoor spaces, while power vented and vacuum fired models are ideal for enclosed areas with proper exhaust routing.

All Combustion Research commercial patio and space heaters operate on Natural Gas (NG) or LP/Propane Gas, providing installation flexibility. The Synergy Dual Stage 200K model is natural gas specific, while most Synergy single stage and all Omega II and Reflect-O-Ray models support both NG and LP configurations to accommodate existing gas supply infrastructure.

The Synergy series of high-intensity ceramic patio heaters reaches maximum operating temperature in less than one minute, providing instant on-demand radiant heat. This rapid heat-up capability is especially valuable in commercial outdoor settings where guests or workers need immediate warmth upon arrival, without the long warm-up wait associated with conventional forced-air systems.
