Key Takeaways
- Infrared heaters provide instant, targeted warmth without heating the air.
- Portable electric heaters are versatile and easy to move.
- Propane heaters offer powerful heat but require ventilation.
- Radiant floor heating is luxurious but needs professional installation.
1. Infrared Heaters (Most Energy-Efficient)
Infrared heaters use electromagnetic waves to warm objects and people directly, making them ideal for screened porches with airflow. Unlike traditional heaters, they don’t lose heat to drafts. Key benefits:
- Instant heat – No waiting for the space to warm up.
- Low energy use – Up to 40% more efficient than convection heaters.
- Silent operation – No noisy fans.
For larger porches, consider a radiant heating comparison to explore alternatives.
2. Portable Electric Patio Heaters (Best Budget Option)
These plug-in heaters are affordable and easy to move. Look for models with:
- Adjustable thermostats – For precise temperature control.
- Tip-over protection – Auto-shutoff if knocked over.
- Weather-resistant housing – For outdoor durability.
They work best in smaller porches (under 150 sq ft).
3. Propane Heaters (Highest Heat Output)
Propane heaters deliver strong, consistent warmth, perfect for colder climates. However, they require proper ventilation to avoid carbon monoxide buildup. Features to consider:
- BTU rating – Higher BTUs = more heat (20,000+ BTUs for large porches).
- Safety certifications – Look for CSA or UL approval.
- Fuel efficiency – Some models last 10+ hours per tank.
4. Electric Fireplace Heaters (Aesthetic + Functional)
These combine ambiance with heating, offering flame effects without real fire. Benefits include:
- No venting needed – Easy to install.
- Adjustable settings – Control heat and flame brightness.
- Space-saving designs – Wall-mounted or freestanding.
5. Radiant Floor Heating (Luxury Option)
Ideal for enclosed porches, this system warms from the ground up. Pros:
- Even heat distribution – No cold spots.
- Hidden installation – No visible units.
- Long lifespan – 20+ years with proper maintenance.

6. Ceiling-Mounted Heaters (Space-Saving)
These free up floor space and provide wide coverage. Look for:
- Low-profile designs – Blend with porch ceilings.
- Oscillation features – For even warmth.
- Waterproof ratings – IP65 or higher for outdoor use.
7. Tabletop Heaters (For Small Porches)
Compact and portable, these are great for spot heating. Features:
- Lightweight – Easy to store when not in use.
- Fast heating – Ceramic elements warm quickly.
- Safety locks – Prevent accidental activation.
