Safety features include an automatic tilt sensor that shuts off the burner if tipped, and a heavy base capable of holding sand or additional weight for wind stability. The design includes wheels and a drink table for portability and convenience. This model is suitable for larger porches, restaurant patios, or semi-enclosed outdoor areas requiring broad radiant coverage.
Dyna-Glo 30,000 BTU Infrared Wall Heater
The Dyna-Glo IR30NMDG-1 is a natural gas infrared wall heater producing up to 30,000 BTU using infrared technology that warms objects directly rather than relying solely on air convection. This radiant approach provides fast, localized warmth comparable to sunlight, making it useful for covered porches or semi-enclosed spaces.
This heater is intended for permanent wall mounting and is natural gas ready. It’s rated to heat up to around 1,000 square feet depending on enclosure and climate. The infrared method reduces heat loss in drafty areas and is effective when occupants are seated near the heat source.
ProCom MN300TPA-B Ventless 30,000 BTU
The ProCom MN300TPA-B is a ventless natural gas infrared space heater rated at 30,000 BTU, designed for both wall mounting and floor placement using included hardware and base feet. It features thermostat control with High/Medium/Low settings to manage comfort and fuel use, and is sized to heat up to approximately 1,400 square feet in optimal conditions.

As a ventless unit, this model produces heat without flue or chimney requirements, relying on indoor combustion while incorporating safety devices typical for vent-free appliances. Its compact profile and thermostat control make it an option for covered porches that permit ventless indoor-style appliances and where local codes allow natural gas ventless units.
Mr. Heater 30,000 BTU Blue Flame Wall
The Mr. Heater MHVFBF30NGT is a vent-free blue flame wall heater delivering up to 30,000 BTU with an integrated thermostat for accurate temperature control. The blue flame design produces convection heat that warms air efficiently and offers steady room temperatures for enclosed or semi-enclosed porches where vent-free operation is permitted.
The unit includes a reliable electric ignition powered by a battery and is engineered for fuel efficiency, providing consistent convection warmth with relatively low fuel consumption. It’s suitable for spaces up to around 1,000 square feet and includes safety features typical of vent-free blue flame appliances.
Buying Guide: Choosing The Right Natural Gas Porch Heater
Selecting the appropriate natural gas porch heater depends on installation type, coverage needs, safety priorities, and local regulations. Below is a structured guide to help compare options and match a heater to your porch environment.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
1. Heater Type And Installation
- Freestanding Patio Heaters: (Fire Sense, Golden Flame) Offer portability and high BTU outputs. Best for open or partially-covered porches; require stable base and clearance.
- Wall-Mounted Infrared Heaters: (Dyna-Glo) Provide directed radiant heat that warms people and surfaces directly. Good for permanent installations on covered porches.
- Ventless Wall or Floor Heaters: (ProCom, Mr. Heater) Provide convection or infrared heat without a flue. Suitable for enclosed or semi-enclosed spaces where ventless appliances comply with local codes.
2. Heat Output And Coverage
- BTU Ratings: Higher BTU (45,000) models cover larger open areas but consume more fuel. 30,000 BTU units can be adequate for smaller porches or semi-enclosed spaces.
- Heat Distribution: Reflector hoods spread radiant heat broadly; infrared warms objects; blue flame convection warms air evenly. Match distribution style to seating arrangements and enclosure level.
3. Safety Features
- Tip-Over/Anti-Tilt Sensors: Important for freestanding units to prevent accidental fire hazards.
- Oxygen Depletion Sensors (ODS) And Auto Shut-Off: Critical for ventless and indoor-rated units to prevent unsafe indoor air conditions.
- Stable Base: Look for heavy bases or ballast options (sand reservoirs) for outdoor stability in breezy conditions.
4. Ignition And Controls
- Electronic Or Rapid Spark Ignition: Provides quick, reliable starts compared to manual pilot lighting.
- Thermostat And Variable Controls: Useful for ventless or wall heaters to maintain consistent temperatures and save fuel.
5. Construction And Durability
- Materials: Stainless steel and powder-coated finishes resist corrosion for outdoor use.
- Reflector Quality: Aluminum reflectors help maximize radiant coverage on patio-style heaters.
6. Ventless Vs. Vented Considerations
- Ventless Units: No flue required; efficient but rely on indoor combustion—check local codes and ventilation requirements for safety.
- Vented/Wall Unit Heaters: Require proper venting or exhaust pathways and may be preferred where indoor air quality or code restrictions prohibit ventless models.
7. Energy Use And Fuel Supply
- Natural Gas Availability: Confirm permanent natural gas supply lines and fittings. Some models may be designed specifically for natural gas and not convertible.
- Operating Efficiency: Infrared and blue flame technologies can be more fuel-efficient for specific scenarios—match to usage patterns.
8. Local Codes, Permits, And Clearance
- Clearance Requirements: Maintain recommended clearances from walls, ceilings, and combustible materials as specified by the manufacturer.
- Codes And Permits: Confirm local building codes and whether ventless heaters are permitted for porches or semi-enclosed structures.
9. Maintenance And Longevity
- Routine Checks: Inspect burners, connections, and ignition systems periodically. Outdoor heaters may need seasonal cleaning to prevent rust and debris buildup.
- Replacement Parts: Verify availability of replacement components such as igniters, thermostats, and ODS sensors for long-term maintenance.
10. Comparison Perspectives
- Coverage Priority: Choose higher BTU freestanding heaters (45,000 BTU) for larger open porches; opt for directed infrared if seated areas need concentrated warmth.
- Safety And Indoor Use: For semi-enclosed porches that are closer to indoor living areas, consider vent-free models only if allowed and with ODS and thermostat control.
- Portability Vs. Permanence: Freestanding units offer portability and seasonal storage; wall-mounted heaters provide permanent installation and often more efficient heat distribution.
