Mastering Outdoor Comfort with Sunpak Gas Infrared Patio Heaters
Discover why Sunpak is the professional choice for high-efficiency, overhead gas heating.
The Science of Sunpak: How Gas Infrared Heating Works
Unlike traditional portable "mushroom" heaters that heat the air, Sunpak infrared heaters emit electromagnetic waves that warm people and objects directly. This "sun-like" radiant heat is unaffected by wind, making it the most efficient way to keep your patio usable during the colder months.
Choosing the Right Sunpak Model for Your Layout
Sunpak offers a streamlined selection of heaters designed for specific mounting heights and heat demands. Understanding the difference between the S25 and S34 series is key to your patio design.
Sunpak S25: The Residential Standard
The S25 delivers 25,000 BTUs and is optimized for lower mounting heights (7.5 to 9.5 feet). It’s the perfect choice for cozy residential seating areas where a gentle, consistent warmth is required without being overpowering.
Sunpak S34: Maximum Heat Output
With 34,000 BTUs, the S34 is engineered for larger spaces or higher ceilings (9 to 12 feet). This model is a favorite for commercial restaurant patios because it provides a wider heat "footprint" and can handle colder ambient temperatures.

Expert Installation Checklist for Sunpak Heaters
To ensure safety and longevity, keep these professional installation requirements in mind:
- Outdoor Use Only: These are unvented gas appliances. They must be installed in spaces with at least two open sides for proper ventilation.
- 24V Power: Sunpak heaters use a 24-volt spark ignition system. You will need a transformer to step down standard 120V power.
- Mounting Angle: For the best heat distribution, Sunpak heaters are typically mounted at a 0 to 30-degree angle.
- Gas Pressure: Ensure your gas line is sized correctly for the total BTU load of all heaters on the circuit to prevent "clicking" or failed ignitions.
Common Questions About Sunpak Heating
Are Sunpak heaters weather-resistant?
Yes, Sunpak heaters are designed for outdoor environments. The 304 stainless steel model is specifically recommended for areas near salt water or heavy rain.
Can I use a Sunpak heater with a remote?
Only the "TSR" models come equipped with a factory-installed remote control system. Standard S25 and S34 models are operated via a wall switch.
How much clearance do I need?
Clearance requirements vary by model, but generally, you need 24 inches of clearance from the top of the heater to any combustible ceiling material.
