Outdoor Gas Heating Options: Gas Space Heaters vs Gas Fire Pits

Author: Sean Summers, NFI Master Hearth Certified Technician – WoodstovePro.com

If you want to extend your outdoor season, gas heating is one of the easiest ways to make a patio, deck, or backyard space usable on chilly nights. The big question homeowners ask is: should you choose an outdoor gas heater designed for heat output, or a fire feature that’s more about ambiance like a gas fire pit? Both can improve patio heating, but they serve different goals, require different setups, and come with different venting options (or none at all).

Here’s a clear comparison to help you choose the best outdoor gas heating solution for your space.

The main difference: heat vs ambiance

A gas space heater is designed primarily to warm people and spaces. A gas fire pit is designed primarily to create a flame centerpiece, with heat as a bonus. Both are enjoyable—but if you’re trying to stay truly warm in colder weather, the “right” choice depends on how you plan to use your patio.

Option 1: Outdoor Gas Space Heater (best for real patio heating)

An outdoor gas heater in the “space heater” category is built for performance. Many models use radiant or infrared heat to warm people and objects directly—especially helpful in breezy conditions.

Best for:

• Covered patios and outdoor seating areas
• Outdoor dining spaces
• Frequent entertaining in cooler months
• People who want dependable warmth, not just flames

Key benefits:

• Strong heat output for targeted patio heating
• Consistent warmth without constantly tending a flame
• Many mounting options: freestanding, wall-mounted, or overhead
• Often better in wind than an open flame feature

Important notes:

• You must choose a unit rated for outdoor use
• Placement and clearances matter
• Some models require professional gas line hookup

If your goal is warmth you can feel, a gas space heater is usually the better tool.

Option 2: Gas Fire Pit (best for ambiance with some warmth)

Gas fire pits create a social focal point—great for gatherings and atmosphere. They provide radiant heat near the flame but usually won’t heat an entire patio like a heater can.

Best for:

• Creating an outdoor “hangout” centerpiece
• Mild-to-cool evenings where ambiance is the priority
• Areas with lower wind exposure
• Homeowners who want décor + flame + some heat

Key benefits:

• Beautiful flames and strong visual appeal
• Easy ignition and control compared to wood fire pits
• Great for conversation areas and outdoor living design
• Less “equipment-looking” than some heaters

Considerations:

• Heat can be less directional and less effective in wind
• You’ll need safe clearance from seating, railings, and structures
• Materials and burner quality matter for long-term reliability

If you want the fire experience first and heat second, a gas fire pit is often the better fit.

Gas heating fuel and setup basics

Both options usually run on:

• Natural gas (utility line)
• Propane (tank)

Your choice impacts installation and convenience:

• Natural gas offers continuous supply but may require a gas line extension
• Propane offers flexibility but requires tank refills and storage

Venting options: what matters outdoors?

For outdoor products, “venting” usually means safe airflow and proper clearance rather than a chimney pipe. However, venting options still matter in a different way:

Outdoor-rated products only

Never use indoor heaters outdoors unless they are specifically rated and approved for outdoor use—and never use outdoor appliances indoors.

Covered patios and airflow

If you’re using gas heating under a covered patio, airflow and placement become critical. You must follow:

• Manufacturer clearance specs
• Local codes and installation guidelines
• Safe distance from ceilings, walls, and combustibles

If your patio is enclosed or semi-enclosed, a professional should help confirm what’s safe and permitted.

Which should you choose? A quick decision guide

Choose an outdoor gas heater / gas space heater if you want:

• Strong, practical patio heating
• More warmth in windy conditions
• Heat directed to seating/dining areas
• A solution for frequent use

Choose a gas fire pit if you want:

• Ambiance and a centerpiece flame feature
• A casual “gather around the fire” experience
• Moderate warmth close to the fire
• A style-forward outdoor upgrade

Many homes actually benefit from both: a fire pit for atmosphere and a space heater for nights when warmth is the priority.

Final thoughts

Outdoor gas heating is all about matching the product to your space and how you use it. For maximum patio heating, a gas space heater usually delivers stronger, more dependable warmth. For ambiance and a social centerpiece, a gas fire pit is hard to beat. Either way, choose outdoor-rated equipment and follow the right clearance and venting options guidance for safe operation.
