Portable gas space heaters offer flexibility and mobility, while fixed models provide permanent heating solutions, making them ideal for different needs and spaces.
Choosing between portable and fixed gas space heaters impacts heating efficiency, installation costs, and long-term comfort. This guide compares their performance, safety features, and ideal applications to help you make the right decision.
What Are Portable Gas Space Heaters?
Portable gas heaters provide temporary, movable heat using propane or natural gas. They’re ideal for:
- Garages and workshops
- Outdoor patios
- Emergency heating
- Supplemental warmth in specific rooms

Portable units like the Duraheat 360° indoor/outdoor heater offer:
| Feature | Advantage |
|---|---|
| No installation | Plug-and-play operation |
| Lower upfront cost | $100-$500 vs $1,000+ for fixed units |
| Flexible placement | Move heat where needed |
Fixed Gas Heating Systems Explained
Permanently installed gas heaters provide whole-space heating through:
- Wall-mounted units
- Central duct systems
- Floor heating cables
- Commercial-grade unit heaters
Key Advantages
Fixed systems like built-in gas heaters deliver:
- Higher BTU output (30,000-200,000 BTU)
- Automatic thermostat control
- Safer venting of combustion gases
- Lower operating costs long-term
Critical Comparison Factors
1. Heating Capacity
Fixed heaters provide 3-5x more heat output. A Bromic Platinum gas heater delivers 46,000 BTU vs 10,000-30,000 BTU for portables.
2. Safety Features
| Feature | Portable | Fixed |
|---|---|---|
| Oxygen depletion sensor | ✓ | ✓ |
| Tip-over switch | ✓ | N/A |
| Professional venting | ✗ | ✓ |
3. Installation Requirements
Fixed units require:
- Gas line plumbing
- Electrical wiring (120V or 240V)
