ProCom MN300TPA-B Ventless Infrared Heater
This ProCom variant delivers infrared heating using natural gas at 30,000 BTU, with thermostat control and included mounting hardware and base feet. Infrared technology radiates heat to objects and occupants rather than relying solely on air convection.
- Heating Mode: Infrared radiation for direct-object heating.
- Control: Built-in thermostat with multiple settings.
- Installation: Can be mounted on a wall or placed on the floor with base feet.
- Coverage: Marketed for spaces up to 1,400 sq. ft.
Infrared models are generally effective for targeted warmth and can feel warmer at lower air temperatures since they heat surfaces and bodies directly.
Mr. Heater MHVFBF30NGT 30,000 BTU Vent Free Heater
The MHVFBF30NGT is a vent-free natural gas wall or floor-mountable heater rated at 30,000 BTU. It features a precise mechanical thermostat, an electric ignition powered by a battery (battery included), and a blue flame burner intended for efficient convection heating.

Buying Guide: How To Choose A Gas Floor Heater
Selecting a gas floor heater requires attention to capacity, installation, safety, fuel compatibility, and room characteristics. Below are key considerations to compare models and determine the best fit for your needs.
Heating Capacity And Room Size
Match the heater’s BTU rating to the room square footage and ceiling height. Higher BTU units cover larger spaces but may be overpowered for small rooms. Ventless heaters list approximate coverage—cross-check with your room volume for accuracy.
Heater Type: Blue Flame Vs Infrared
- Blue Flame (Convection) — Heats the air in a room for even warmth. Good for whole-room, continuous comfort.
- Infrared (Radiant) — Warms objects and people directly. Effective for targeted warmth and can feel warmer at lower air temps.
Ventless (Vent-Free) Versus Vented
Ventless heaters are easier to install and offer higher indoor efficiency but require adequate indoor air quality and adherence to local codes. Confirm whether ventless operation is permitted in your area. Vented or direct-vent options exhaust combustion gases outdoors and may be required in some jurisdictions.
Fuel Compatibility And Conversion
Confirm natural gas compatibility if that is your fuel source. Some heaters are LP convertible; others are natural gas only and prohibit conversion. Choose models that match your supply or include approved conversion kits if needed.
Safety Features
- Oxygen Depletion Sensor (ODS) — Shuts off the heater if oxygen levels fall below safe thresholds.
- Automatic Shut-Off — Protects against over-temperature or tip-over (if applicable).
- Thermostat Control — Enables temperature regulation to avoid overheating and reduce fuel use.
Installation And Placement
Decide if you need a floor-mounted model with base feet or a unit that can be wall-mounted. Wall mounting may require clearances and supports; floor placement needs adequate clearance from combustibles and adherence to manufacturer minimum distances.
Ignition And Power Requirements
Some ventless units use battery-powered electric ignition, while others use piezo or manual ignition. If power outages are a concern, models that do not require mains electricity or rely on battery ignition may offer continuous operation.
Efficiency And Operating Costs
While ventless heaters often list high efficiency due to lack of flue losses, actual cost depends on local gas rates and usage patterns. A thermostat and cycling control can save fuel by avoiding unnecessary runtime.
Local Codes And Venting Rules
Verify local building codes regarding ventless gas heaters. Some areas restrict or ban ventless combustion appliances indoors. Always follow local regulations and consult a licensed installer if required.
Maintenance And Serviceability
Look for accessible burners, replaceable parts, and manufacturer support. Routine inspection of gas connections and periodic cleaning of the burner and pilot area help reliable operation and safety.
Comparison Perspectives
- Performance: Compare BTU output to room size; consider infrared for targeted comfort and blue flame for whole-room convection.
- Control: Thermostat models offer temperature stability; manual models provide simplicity and fewer electronics.
- Installation Flexibility: Models with both base feet and wall-mount hardware offer the most placement options.
- Safety: Prioritize ODS and automatic shut-off features for indoor ventless use.
When choosing, balance capacity, control features, safety, installation, and local code compliance to select a gas floor heater that suits your space and usage patterns. For complex installations or code questions, consult a qualified heating contractor or local authorities.
