Finding the right industrial heating system often involves compromise. Many systems underdeliver on energy efficiency, installation flexibility, or long-term durability.
The SunStar SG3-N aims to change that. With 30,000 BTU/hr of infrared ceramic heat, it brings targeted warmth and impressive efficiency to large, hard-to-heat spaces.
Designed specifically for commercial environments, it’s a heating solution built for performance, not just power.
How It Provides Efficient, High-BTU Heating
The SG3-N is engineered for commercial-grade performance, with a design that emphasizes direct infrared heat delivery rather than traditional convection.
- Emits 30,000 BTU/hr of focused radiant heat using natural gas.
- Uses ceramic infrared panels to radiate warmth directly to people and objects.
- Offers faster recovery in large spaces, especially where air circulation alone falls short.
How the Technology Improves Heating Efficiency
Instead of heating air that quickly dissipates, the ceramic elements radiate medium-to-long-wave infrared heat, similar to the sun warming the ground.
- Minimizes heat loss from stratification—ideal for tall ceilings and open doors.
- Reduces duct losses, common in forced-air systems.
- Lowers operating costs by delivering heat directly to occupied areas.
- Saves 30–50% in energy compared to similar forced-air systems.
How It’s Built to Last in Harsh Conditions
Every component of the SG3-N is built with industrial use in mind.
- Corrosion-resistant aluminized steel housing withstands moisture and airborne contaminants.
- Aluminum reflectors direct radiant energy efficiently.
- Compact dimensions (26.5″ W x 15.75″ D x 7.75″ H) and 34 lb weight make it manageable for overhead mounting.
- Comes fully assembled to simplify installation.
How It Installs Safely and Flexibly
The SG3-N supports multiple mounting methods and offers clear clearance guidance to maintain safety and effectiveness.
- Certified for wall or ceiling mounting at up to 30° angle.
- Requires 12-foot minimum height from floor for safe operation.
- Clearances: 31″ side, 37″ ceiling, 73″ below, 51″ front (angled), and 31″ rear (angled).
- Direct spark ignition on 120V with just 0.4 amps of draw.
- Comes with 120/24V transformer and CSA certification for North American safety compliance.
How Ventilation and Gas Supply Requirements Work
For safe and efficient combustion, the SG3-N has defined airflow and gas pressure standards.
- Requires 120 CFM ventilation airflow (4 CFM per 1,000 BTU).
- Operates at 6″ WC burner pressure, with acceptable input pressure from 7–14″ WC.
- Uses a 1/2″ NPT female gas connection, compatible with most natural gas lines.
How Safety and Reliability Are Maintained
This heater incorporates built-in safety systems to ensure worry-free operation in busy environments.
- Includes 100% gas shut-off if irregularities are detected.
- Features no standing pilot—direct spark ignition simplifies operation and improves reliability.
- Test-fired at the factory to ensure correct calibration.
- Designed only for indoor use in commercial or industrial spaces.
- Backed by a 1-year limited warranty (installation must meet guidelines).
How It Performs in Industrial Applications
Ideal for spaces that are hard to heat using traditional air-based systems.
- Performs well in warehouses, machine shops, garages, hangars, and loading areas.
- Best suited for 600–1,000 sq ft zones depending on ceiling height and insulation.
- Infrared heat makes it perfect for high-ceiling areas and frequently opened spaces.
How Operating Costs Compare
The SG3-N offers energy-efficient performance over time, making it a cost-effective option for many businesses.
- Consumes 30 cubic feet of gas per hour at full output.
- Operating cost ranges from $0.30–$0.50/hour, depending on gas rates.
- Lower heat loss means less run time compared to forced-air systems.
How Users Rate the SG3-N
Feedback has been largely positive across distributors and early buyers.
- Rated 4.7 out of 5 stars on Northern Tool.
- Users praise the fast warm-up and silent, sun-like heat.
- Durable construction earns approval in heavy-use environments.
- Most common challenge: professional installation is strongly advised due to mounting and gas connection complexity.
Why It’s a Smart Investment
While infrared heaters can carry a higher upfront price, they often pay for themselves in just a few seasons of reduced operating costs.
- Eliminates ductwork losses, cuts down heat stratification, and boosts comfort near workstations.
- Ideal for zoned heating, allowing selective warmth rather than heating unused space.
- Comes with heater unit, transformer, and operation manual—all ready for installation.
For companies needing consistent warmth in tough environments, the SG3-N is a practical choice that combines power, efficiency, and reliability.
By investing in infrared ceramic technology, facilities can reduce heating costs while creating a more comfortable workspace for employees—even in winter’s harshest months.
