Natural gas and propane patio heaters can both make cool evenings more usable. The right choice depends less on the heater alone and more on how your outdoor space is built.
Quick answer
Choose natural gas when the heater will live in one main location and your patio is near an existing gas meter, appliance line, or planned outdoor gas stub. Choose propane when you need portability or do not want to run a fixed gas line.
In broad terms, natural gas already serves a large share of American homes through furnaces, water heaters, ranges, dryers, and other appliances. For those homes, a natural gas patio heater can extend an energy source that is already installed instead of relying on portable propane tanks.
Natural gas vs propane patio heaters
| Question | Natural gas | Propane |
|---|---|---|
| Best use case | Fixed patios, outdoor rooms, restaurants, and spaces near an existing gas line. | Flexible seating areas, renters, temporary setups, and patios without gas service. |
| Fuel source | Connected to the home or building’s natural gas supply. | Uses portable propane cylinders, usually a 20 lb tank for residential heaters. |
| Convenience | No tank swaps, no spare cylinders, no half-empty tank during a gathering. | Easy to move, but tanks need to be refilled, exchanged, stored, and checked. |
| Installation | Requires proper line sizing, shutoff valve, fittings, and professional installation. | Usually simpler to set up, but still requires safe outdoor use and tank handling. |
| Portability | Best treated as a fixed heat source. | Best when the heater needs to move around the patio. |
When natural gas is the better choice
Natural gas is the premium-practical option for patios that act like outdoor rooms. If your seating area is always in the same place, a fixed heater can feel more integrated with the space: no visible tank, no storage run, and no interruption when the evening gets cold.
- You already have natural gas at home. Homes with gas furnaces, water heaters, dryers, ranges, or outdoor stubs may be easier candidates for a professionally installed patio heater line.
- You use the patio often. If the heater is part of a regular seating or dining area, utility-supplied fuel is simpler than managing tanks.
- You want a cleaner patio layout. Natural gas avoids the visual bulk of a propane cylinder and keeps the heater tied to the outdoor room.
- You are planning a restaurant, bar, or serious backyard setup. Fixed fuel makes sense when outdoor comfort is part of the space’s core function.
When propane is the better choice
Propane still has a real place. It wins when the patio is flexible, the heater needs to move, or a fixed gas line does not make sense.
- You move furniture often. A propane heater can follow the seating layout.
- You do not have a practical gas-line location. Running a new line may not be worth it for occasional use.
- You rent or cannot modify the property. Propane avoids permanent installation work.
- You want a simpler first purchase. A propane setup can be easier to start with, provided it is used outdoors and according to the heater manual.

Technical planning checklist
Before choosing any gas patio heater, think about the space as a system. The heater, fuel source, wind exposure, clearances, and installation all matter.
- BTU output: Higher BTU ratings can help in larger or more open areas, but placement and wind exposure affect comfort.
- Gas line sizing: A qualified professional should confirm the line can support the heater’s fuel demand.
- Shutoff and fittings: Natural gas installations should include proper shutoff valves and approved fittings.
- Clearance: Follow the product manual and local code for distance from walls, ceilings, furniture, umbrellas, and combustible materials.
- Wind: Open, windy patios may need different placement or multiple heat sources.
Bottom line
If the heater belongs to a fixed patio layout, natural gas usually feels cleaner and more convenient over time. If the heater needs to move or the space is temporary, propane is usually the practical choice.
For a permanent outdoor room, start with Golden Flame’s natural gas patio heaters. If you are not sure what fits your space, send Golden Flame support a note with your patio layout, fuel type, and any existing gas-line details.
FAQ
Can I connect a natural gas patio heater myself?
Natural gas work should be handled by a qualified professional. Line sizing, shutoff valves, fittings, leak testing, and local code matter.
Is natural gas cheaper than propane?
In many areas, natural gas is a cost-effective utility fuel, but local rates vary. The bigger everyday advantage is convenience: no refilling, exchanging, or storing tanks.
Does a natural gas heater put out as much heat as propane?
Compare heaters by their rated BTU output, but remember that BTUs are only one part of comfort. Placement, wind exposure, reflector design, and the size of the outdoor space all affect how warm the patio feels.
Should restaurants use natural gas patio heaters?
Often, yes. For fixed outdoor dining areas, natural gas can reduce tank handling and keep the patio ready for repeated use. Installation still needs to follow local code and professional guidance.
