Dyna-Glo IR30NMDG-1 30,000 BTU Wall Heater
Type: Natural gas infrared wall heater. Key Features: Up to 30,000 BTU, natural gas ready, radiative infrared heating that warms objects first, coverage up to 1,000 sq. ft.
This unit uses infrared radiation to heat surfaces and people directly, similar to the way sunlight warms objects. Because it’s designed as a wall-mounted heater, it’s suitable for garages, workshops, and sunrooms where direct, quick radiant heat is desired. The manufacturer specifies that fuel conversion is not permitted, so ensure the model matches your home fuel supply.
Installation considerations include wall location, clearances, and venting per local code. Infrared wall heaters are often appreciated for producing focused, immediate warmth in occupied zones without needing to heat the entire air volume of a room.
ProCom MN300TPA-B Ventless Infrared Space Heater

Type: Ventless natural gas infrared heater. Key Features: 30,000 BTU, thermostat control with High/Medium/Low settings, heats up to 1,400 sq. ft., includes wall mount and base feet.
This ProCom model blends infrared radiant heating with a ventless design intended for residential spaces. The built-in thermostat and multiple output settings enable more tailored comfort control for different room sizes and occupant needs. Because it’s ventless, it releases combustion byproducts into the room; verify local codes and indoor air quality considerations before installation.
Mounting options are flexible — wall-mounted or floor-mounted with included feet — which can simplify placement. The design and controls emphasize practical room-level heat management and installation versatility.
ProCom MN300HBA-B Ventless Blue Flame Heater
Type: Ventless blue flame natural gas heater. Key Features: 30,000 BTU, manual control with three heat settings, push-button ignition, oxygen depletion sensor (ODS) included, heats up to 1,400 sq. ft.
Although this model is primarily a blue flame convection heater rather than a pure infrared radiator, it’s commonly grouped with space heaters for supplemental heating. Blue flame heaters transfer heat through convection and radiant components and are designed to heat air and surfaces. The manual controls and lack of required electricity (piezo ignition) make it suitable for areas where electrical access is limited.

Safety features such as the ODS automatic shut-off provide a protective measure against oxygen depletion. Ventless appliances require adherence to ventilation guidelines and local regulations because combustion products are released indoors.
Dr Infrared Heater DR-238 Carbon Infrared Outdoor Heater
Type: Electric carbon infrared patio and indoor heater. Key Features: IP55 rated for indoor/outdoor use, three power settings (900W, 1200W, 1500W), remote control, instant odorless heat, 120V plug-and-go operation.
While this model is electric rather than gas-fueled, it represents an infrared solution well-suited to patios, decks, and semi-enclosed outdoor dining. Carbon infrared elements deliver direct radiant warmth and the IP55 rating supports exposure to outdoor conditions when installed per guidelines. Multiple heat settings and a remote offer convenient control for varied comfort needs.
Electric infrared heaters are typically easier to deploy than gas models because they require only standard electrical power and no combustion venting. They are often chosen for outdoor or covered areas where gas lines or venting would add complexity.
Mr. Heater MHVFBF30NGT 30,000 BTU Vent Free Blue Flame
Type: Vent-free blue flame natural gas wall heater. Key Features: 30,000 BTU, precision thermostat control, battery-powered electric ignition, efficient blue flame burner, effective up to 4,500 feet altitude, suitable for rooms up to 1,000 sq. ft.
The Mr. Heater vent-free blue flame model delivers consistent convection heat with a blue flame burner that includes a thermostat for temperature regulation. It’s designed to convert cold rooms and additions into comfortable spaces without venting. The emphasis is on steady, fuel-efficient heat rather than directional radiant infrared heating.
When considering a vent-free model, check local building codes and indoor air quality effects. The built-in thermostat allows more precise room temperature control than many basic unit heaters.
Buying Guide: Choosing The Right Infrared Or Gas Heater
Selecting a heater involves matching fuel type, heating method, room characteristics, and safety requirements. Below are core factors to evaluate when choosing an infrared or gas heater.
Heat Type: Infrared Versus Convection
- Infrared (Radiant) Heat: Warms people and objects directly. Best for targeted warmth in workshops, patios, garages, and seating areas. Faster perceived warmth at lower ambient temperatures.
- Convection / Blue Flame: Warms air and circulates heat throughout a room. Better for general, whole-room warming and maintaining a steady ambient temperature.
Fuel Source And Availability
- Natural Gas / Propane: Common for high-BTU permanent installations. Requires gas supply, proper connections, and adherence to venting or ventless code.
- Electric Infrared: Plug-and-play convenience with no combustion byproducts. Often chosen for outdoor, patio, or spaces without gas lines.
Ventilation And Code Considerations
- Ventless Models: No external venting required, but combustion products enter the room. Confirm local regulations and ensure adequate indoor ventilation.
- Vented / Direct-Vent Models: Route combustion byproducts outdoors; necessary in some jurisdictions and for enclosed spaces where indoor air quality must be preserved.
BTU Output And Coverage
- Match BTU capacity to square footage and ceiling height. Higher BTUs suit larger spaces or poorly insulated areas.
- Estimate coverage: 30,000 BTU is typical for 800–1,400 sq. ft. depending on insulation, ceiling height, and climate.
Installation Flexibility
- Wall Mount vs Floor: Wall-mounted infrared units provide directed warming; floor or portable units offer mobility.
- Electrical Needs: Some gas heaters require a small electrical connection for fans or ignition; verify power availability.
Safety Features
- ODS (Oxygen Depletion Sensor): Important in ventless gas heaters to automatically shut off on low oxygen.
- Thermostat & Controls: Built-in thermostats improve comfort and efficiency. Remote control adds convenience for outdoor electric heaters.
- Clearance And Placement: Observe manufacturer-specified clearances to combustibles and floor/ceiling distances.
Indoor Air Quality And Occupancy
- Ventless gas heaters release water vapor and combustion byproducts; in bedrooms or tightly sealed spaces consider vented options or electric infrared.
- For allergy-sensitive occupants, radiant electric heaters produce no combustion emissions.
Durability And Intended Use
- Outdoor Use: Choose IP-rated electric infrared units or purpose-built outdoor gas heaters designed to withstand weather exposure.
- Workshop / Garage: Infrared gas or unit heaters with higher BTUs perform well in spaces with intermittent use where immediate heat is desired.
Maintenance And Operating Costs
- Gas heaters typically have lower fuel costs per BTU than electric in many regions, but require periodic inspection and potential vent cleaning when applicable.
- Electric infrared requires minimal maintenance but may have higher operating costs depending on electricity rates.
Comparison Perspectives
- Performance: Infrared models (both gas and electric) provide faster perceived warmth for occupants in targeted zones; convection units maintain room temperature more uniformly.
- Flexibility: Portable electric infrared units win for ease of installation and outdoor use; gas units offer higher BTU outputs for larger indoor spaces.
- Safety And Code: Vented gas options are safest for air quality in enclosed spaces; ventless units require careful adherence to local guidelines.
- Cost Over Time: Assess fuel price trends, initial installation, and expected runtime to estimate lifecycle operating expenses.
Use the above criteria to determine which product characteristics align with your space, installation capability, and comfort priorities. When in doubt, consult a licensed HVAC or gas professional for site-specific guidance and safe installation practices.
