Mr. Heater Portable Buddy MH9BX
This portable propane radiant heater uses advanced infrared technology to heat objects and people directly rather than relying solely on air circulation. Output ranges from 4,000 to 9,000 BTU, making it appropriate for areas up to about 225 sq. ft. The unit emphasizes portability for campers, workshops, and patios.
Safety and ignition features include an improved tip-over switch that audibly engages if the heater is moved, and a Piezo igniter that starts the unit without matches, batteries, or external flame. The radiant design produces localized, sun-like warmth and can be used indoors where allowed by local codes and manufacturer instructions.
ProCom MN300TBA-B Blue Flame
The ProCom MN300TBA-B is a ventless blue flame natural gas heater with a maximum output of 30,000 BTU and a stated heating coverage up to 1,400 sq. ft. It offers thermostat control with High/Medium/Low settings for temperature regulation and can be wall-mounted or placed on the floor using included base feet.

Its slim profile combines functionality and aesthetics for use in offices, bedrooms, or living spaces. As a ventless model, it vents combustion products into the room, so proper ventilation and code compliance are important considerations when installing.
ProCom MN300TPA-B Infrared
This ProCom model is a ventless infrared natural gas heater also rated at 30,000 BTU and designed to heat up to 1,400 sq. ft. Infrared operation radiates heat to objects in the room, producing a direct-warmth effect similar to sunlight. Thermostat control provides High/Medium/Low settings to maintain comfort.
Like other ventless units, the MN300TPA-B is intended for indoor residential use where local codes allow. The unit’s design supports wall mounting or freestanding placement, and it emphasizes even heat distribution via infrared heating elements.
Dyna-Glo IR30NMDG-1 30,000 BTU
The Dyna-Glo IR30NMDG-1 is a natural gas infrared wall heater that delivers up to 30,000 BTU/hr and radiates heat to warm objects and occupants directly. Manufacturer guidance lists coverage up to approximately 1,000 sq. ft., making it suitable for garages, workshops, or larger living spaces.

This model is built for natural gas supply and does not permit fuel conversion. The infrared mechanism provides focused radiant warmth and can be a practical choice where wall mounting is preferred to free up floor space.
Mr. Heater MHVFBF30NGT Wall Mount
The Mr. Heater MHVFBF30NGT is a vent-free blue flame natural gas wall heater rated at 30,000 BTU, intended to heat spaces up to about 1,000 sq. ft. It features a built-in thermostat for precise temperature control and includes a battery for electric ignition to aid reliable startup.
Blue flame convection heating provides even air circulation and efficient fuel consumption. The unit is specified for altitude performance up to 4,500 feet and emphasizes fuel efficiency in its blue flame burner design. Installation options and local code compliance should be evaluated prior to mounting.
Buying Guide: How To Choose A Gas Space Heater
Selecting the right gas space heater requires balancing fuel type, heating technology, capacity, installation, and safety. The following guide breaks down the key factors to consider across multiple comparison perspectives.
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. Fuel Type And Availability
- Propane (LP): Portable options like the Mr. Heater Portable Buddy use propane cylinders; ideal for camping, outdoor patios, or locations without natural gas lines.
- Natural Gas: Fixed-installation units such as ProCom and Dyna-Glo models connect to household gas lines and are suitable for consistent indoor heating needs.
- Conversion Considerations: Some units are fuel-specific and do not permit conversion between propane and natural gas; check manufacturer specifications before purchase.
2. Heating Technology: Radiant, Infrared, Blue Flame
- Radiant Heaters: Heat objects and people directly for immediate localized warmth; effective in smaller areas or outdoor settings where air exchange reduces convection efficiency.
- Infrared Heaters: Radiate heat similarly to sunlight, warming surfaces first; good for garages, workshops, or spaces where spot heating is preferred.
- Blue Flame/Convection Heaters: Heat air and circulate warm air through the space, providing more even whole-room heating for living areas.
3. Capacity And Room Size
- Match BTU output to square footage and insulation quality. Higher BTU ratings (20,000–30,000 BTU) suit larger rooms or poorly insulated spaces; lower outputs (4,000–9,000 BTU) are for small rooms or spot heating.
- Consider ceiling height, drafts, and building layout; manufacturers often provide an estimated coverage area which should be interpreted conservatively.
4. Venting And Installation
- Ventless (Vent-Free) Units: Do not require a chimney or flue but release combustion byproducts into the room. Ensure local codes permit ventless heaters and provide adequate ventilation.
- Wall-Mounted vs. Freestanding: Wall-mounted units save floor space and may offer better placement options; freestanding and portable units allow flexible placement and relocation.
- Professional installation may be required for natural gas connections or to meet local regulations.
5. Safety Features
- Tip-Over Switches: Essential for portable units to automatically shut off if tipped or jostled.
- Oxygen Depletion Sensors (ODS): Common on vent-free heaters to shut off the unit if oxygen levels drop below safe thresholds.
- Certified Ignition Systems: Piezo or electric ignition reduces reliance on open flames or manual lighting, improving safety.
6. Controls And Convenience
- Thermostat Control: Allows automatic cycling to maintain a set temperature and improve fuel efficiency.
- Variable Heat Settings: High/Medium/Low settings provide flexibility for managing output and comfort.
- Remote Operation & Timers: Some models support remote control or programmable timers for convenience.
7. Efficiency And Operating Cost
- BTU Per Hour vs. Efficiency: Higher BTU does not always mean better efficiency. Look for blue flame burners or ventless infrared units that claim high combustion efficiency.
- Usage Pattern: Intermittent spot heating favors radiant or portable propane units; whole-home supplemental heating may favor natural gas wall units with thermostats.
8. Noise, Aesthetics, And Placement
- Blowers and Fans: Units with blowers provide faster warm-air distribution but can add noise. Infrared and radiant heaters are typically quieter.
- Design and Finish: Slim profiles and decorative logs in some ventless fireplaces can better integrate into living spaces.
- Clearances: Verify manufacturer-recommended clearances from walls, furniture, and combustible materials before installation.
9. Code Compliance And Local Regulations
- Check local building codes and fire regulations regarding ventless appliances, combustion appliances in bedrooms, and required clearances.
- Some jurisdictions restrict vent-free heaters in certain room types or require specific installations; confirm before purchase and installation.
10. Comparison Perspectives
- Portability vs. Permanence: Portable propane units offer mobility at the cost of lower maximum BTU and reliance on cylinder supply. Fixed natural gas units provide higher continuous output but require piping and installation.
- Spot Heating vs. Whole-Room Heating: Radiant/infrared heaters excel at spot heating and immediate warmth. Blue flame convection units distribute heat to fill a room more evenly for sustained comfort.
- Efficiency vs. Venting: Vent-free designs maximize in-room heat but require attention to indoor air quality; vented systems exhaust combustion products but need ducting or flues.
