Gas Patio Heater

Picture a restaurant patio on a cool evening, guests lingering over dinner, warmth radiating from overhead without a single propane tank in sight. That’s the advantage of a natural gas patio heater. Connected directly to a continuous gas line, these heaters deliver reliable infrared radiant heat for hours without interruption or fuel changes.

This collection includes permanent post models, portable freestanding units, and wall-mounted infrared heaters from Sunglo and Sunpak. Whether you’re outfitting a commercial dining space or extending your home patio season, Fire Pit Surplus carries gas heaters for outdoors built for both settings.

Why Choose a Natural Gas Patio Heater?

Continuous Fuel Supply

A direct gas line means no propane tanks to swap or run out of mid-service. Your heater stays lit as long as you need it, ideal for restaurants, resorts, and frequent home use.

Lower Long-Term Operating Cost

Natural gas costs significantly less per BTU than propane over time. For commercial outdoor heaters running nightly through a full season, the savings add up quickly.

Commercial-Grade Reliability

Restaurants and hospitality venues depend on consistent heat to keep outdoor dining comfortable. With U.S. restaurant sales projected at $1.55 trillion in 2026 per the National Restaurant Association, outdoor seating is a revenue driver and reliable heating makes it viable year-round.

Flexible Installation Options

Natural gas outdoor heaters for patios come in permanent post, freestanding, and overhead wall-mounted configurations. Pair them with electric patio heaters in covered zones for full-property coverage.

Natural Gas vs. Propane: Which Patio Gas Heater Is Right?

Natural Gas

Natural gas heaters connect to a continuous gas line, eliminating tank refills and reducing long-term fuel costs. They're the preferred choice for permanent installations with consistent nightly use, especially restaurant patio heaters and resort properties.

Propane

Propane heaters run on 20 lb. tanks, making them portable and simple to set up without a gas line. They suit seasonal use, events, and freestanding patio heaters where permanent plumbing isn't practical. Both fuel types deliver effective infrared heat; the right choice depends on your installation and usage frequency.

How to Choose the Right Patio Natural Gas Heater

Installation Type

  • Permanent Post: In-ground models like the Sunglo PSA265 are fixed in place, ideal for open patios with dedicated gas lines.

  • Freestanding Portable: The Sunglo A270 connects via quick-disconnect hose and can be repositioned or stored between seasons.

  • Wall or Ceiling Mounted: Infrared units like the Sunpak S34 mount overhead, keeping floor space clear, preferred for covered patio heater setups.

BTU Output & Coverage Area

  • 40,000–50,000 BTUs: Standard for open patios and commercial dining. Space units approximately 12 feet apart for even coverage.

  • 25,000–34,000 BTUs: Appropriate for covered patios where infrared radiant heat is directed downward from wall-mounted units.

  • Multiple Heater Layouts: Larger venues combine high BTU patio heaters with overhead infrared units to cover open and sheltered zones.

Residential vs. Commercial

  • Residential: Manual or semi-automatic ignition works well for homeowners. Prioritize stainless steel and weather resistance.

  • Commercial: Choose automatic ignition with 24-volt controls for multi-unit ease. CSA certification and wind-rated designs are essential.

  • Code Compliance: Commercial installs may require specific clearance requirements, mounting heights, and professional gas line connections.

Material & Weather Resistance

  • Stainless Steel: Most durable for outdoor use. Resists corrosion and UV degradation through years of exposure.

  • Powder Coated Finish: Available in black on select Sunglo models. Sleek aesthetic at a lower price point with solid weather protection.

  • Aluminum Reflectors: Deep-dish aluminum on Sunglo post and portable models maximizes heat distribution and resists rust.

Frequently Asked Questions

How much does it cost to run a natural gas patio heater?

A 50,000 BTU unit typically costs $1.50 to $3.00 per hour depending on local gas rates, significantly less than propane over a full season, especially for commercial properties running heaters nightly.

Can I convert a propane patio heater to natural gas?

Not all models support fuel switching. Sunglo and Sunpak build dedicated natural gas and propane versions rather than conversion models. Always confirm with the manufacturer's specifications before attempting any conversion.

How many BTUs do I need for an outdoor patio heater?

For open patios, 40,000 to 50,000 BTUs per heater is standard with units spaced about 12 feet apart. Covered spaces can use 25,000 to 34,000 BTU wall-mounted infrared models for effective heating at lower output.

Are natural gas patio heaters safe on a covered patio?

Yes, provided you maintain the manufacturer's recommended clearance between the heater and overhead structures. Wall-mounted infrared models like the Sunpak S34 are designed for covered patios with minimum mounting heights of 8 to 10 feet.

What is the difference between infrared and conventional gas patio heaters?

Infrared heaters warm people and objects directly through radiant energy rather than heating the air. This makes them more fuel efficient and wind resistant, which is why infrared models are preferred for open or breezy commercial patios.
