When temperatures drop, a porch heater can extend the usability of your outdoor space. Choosing the right one depends on several factors, including the size of your area, fuel type, and specific heating needs. Here’s what to consider before you buy.
Quick answer: For small porches under 150 sq ft, an electric infrared heater under $150 provides focused heat and easy installation. Larger areas up to 400 sq ft often require propane heaters, starting at $250, or natural gas systems for consistent warmth. Always measure your porch and opt for models with safety features like tip-over protection.
Types of Porch Heaters
Porch heaters come in various types, each suited to different outdoor setups. Here’s a breakdown:
Electric Infrared Heaters
Electric heaters are ideal for small spaces. They’re plug-and-play, with no need for fuel storage. Infrared models heat objects directly, making them efficient in targeted areas.
- Best for: Small enclosed porches, patios under 150 sq ft
- Price range: $100-$250
- Key features: Quiet operation, no emissions, easy wall mounting
Popular models include the Heat Storm HS-1500-PHX ($149) and Dr. Infrared Heater DR-238 ($169).
Propane Heaters
Propane heaters deliver higher BTU output, making them suitable for larger open spaces. They typically feature portability and quick heating.
- Best for: Open porches, areas up to 400 sq ft
- Price range: $200-$400
- Key features: Adjustable heat levels, safety shut-offs
A standout option is the Mr. Heater MH18B ($229), which offers 18,000 BTUs and tip-over protection.
Natural Gas Heaters
If you’re planning permanent outdoor heating, natural gas heaters are reliable and cost-effective in the long term. They require professional installation.
- Best for: Large porches or patios, semi-permanent setups
- Price range: $300-$600 (installation extra)
- Key features: Continuous fuel supply, no tank refills
Consider the Dyna-Glo DGPH202SS ($329) for consistent performance and sleek design.
Pro tip: Compare fuel costs before committing. Propane tanks cost $3-$6 per hour, while natural gas averages $1-$2 per hour.
Key Features to Look For
When choosing a heater, focus on features that enhance performance and safety:
Wattage and BTU Rating
Heating capacity matters. Electric heaters are rated in watts, while gas heaters use BTUs. For uncovered areas, aim for 20 BTUs per square foot. Enclosed spaces require less, about 10-15 BTUs per square foot.
Safety Mechanisms
Look for models with automatic shut-offs for tip-overs or oxygen depletion. These features aren’t optional, they’re critical.
Portability vs. Fixed Installation
Portable heaters offer flexibility but may require frequent refueling. Fixed units, especially natural gas systems, provide stable, long-term heating.
Weather Resistance
Outdoor heaters should withstand rain and wind. Stainless steel builds resist corrosion and extend product life.

Cost Comparison of Popular Models
| Heater Type | Model | Price ($) | BTU/W Output | Best For | |---------------------|------------------------|-----------|--------------|--------------------------| | Electric Infrared | Heat Storm HS-1500-PHX | 149 | 1,500 W | Small enclosed porches | | Propane | Mr. Heater MH18B | 229 | 18,000 BTUs | Open spaces up to 400 sq ft | | Natural Gas | Dyna-Glo DGPH202SS | 329 | 40,000 BTUs | Permanent setups |
Surprising insight: In 80% of cases, electric infrared heaters cost less to operate over a year compared to propane models, according to Energy.gov’s 2025 efficiency report.
Maintenance Tips for Longevity
Proper care extends the lifespan of your heater. Follow these steps:
- Clean filters regularly: Blocked filters reduce efficiency and increase energy use.
- Inspect hoses and connections: Check for leaks every 6 months, especially in propane systems.
- Store safely: When not in use, keep portable heaters in a dry area to prevent rust.

FAQ
What’s the most energy-efficient porch heater?
Electric infrared heaters like the Dr. Infrared Heater DR-238 ($169) are the most energy-efficient. They focus heat directly, reducing waste.
How much does it cost to run a propane heater?
Propane costs $3-$6 per hour on average, depending on tank size and local prices. A 20 lb tank typically lasts 8-10 hours.
Can I use an indoor heater outdoors?
No, indoor heaters aren’t designed for weather exposure and lack necessary safety features for outdoor use.
How do I install a natural gas heater?
Natural gas heaters require professional installation. Costs vary, but expect $200-$500 for labor and permits.
What heater works best in windy conditions?
Propane heaters with higher BTU ratings (like Mr. Heater MH18B) perform better in wind. They provide stronger radiant heat that resists dissipation.
