ProCom MN300HBA-B Ventless Blue Flame Heater
This ProCom model is a vent-free blue flame natural gas heater rated at 30,000 BTU for spaces up to 1,400 sq. ft. It operates on natural gas only and does not require electricity, using a push-button piezo ignition. Controls are manual with three heat settings: Low, Medium, High. Safety features include an Oxygen Depletion Sensor (ODS) that automatically shuts off the unit if insufficient oxygen is detected. The unit includes base feet so it can be floor-mounted if preferred.
Relevance: This model is useful where non-electric operation is desired and where a simple, robust blue-flame convection heater is preferred. It lacks an integrated blower but provides strong BTU output for larger rooms.
Comfort Glow 30,000 BTU Natural Gas Infrared Wall Heater
The Comfort Glow heater uses infrared radiant technology to warm objects and people directly rather than primarily heating air. It delivers 30,000 BTU and is rated for up to 1,250 sq. ft. Installation is designed for wall mounting, and a floor mounting kit is available separately. This model requires no electricity for operation and uses piezo ignition, making it a candidate for off-grid or power-outage scenarios.

Relevance: Infrared wall heaters are suitable when targeted, direct warmth and quick comfort are preferred—for living areas, garages, or workshops. No integrated blower is present, but radiant heat performance differs from convection blue-flame units.
Dyna-Glo IR30NMDG-1 30,000 BTU Infrared Wall Heater
The Dyna-Glo IR30NMDG-1 is a 30,000 BTU natural gas infrared wall heater that radiates heat to warm objects first, similar to sunlight. It is designed to heat up to 1,000 sq. ft. and is factory-set for natural gas (fuel conversion is not permitted). Infrared heating typically yields faster perceived warmth in the occupied area without having to heat the entire air volume.
Relevance: This model is relevant for users seeking radiant heat performance in medium-sized rooms. It does not include a blower; compare radiant vs convection performance when selecting a unit for living spaces.
Mr. Heater 20K – 30K Natural Gas Heater With Blower Kit
This listing bundles a Mr. Heater vent-free blue flame natural gas heater (compatible 20,000 and 30,000 BTU models) with a blower fan kit. The kit is intended for Mr. Heater models produced from 2016 onward and includes a three-position rocker switch to control blower operation. Adding a blower converts primarily convection heating into forced-air distribution, increasing circulation and improving heat distribution in the room.

Relevance: For readers specifically searching for a natural gas wall heater with blower, this item directly addresses that need by offering compatibility and the fan kit. Verify model compatibility and installation requirements before purchase.
Mr. Heater MHVFBF30NGT 30,000 BTU Vent Free Blue Flame Heater
The MHVFBF30NGT from Mr. Heater is a vent-free blue flame wall heater with thermostat control and a reliable electric ignition. Rated at 30,000 BTU and intended for up to about 1,000 sq. ft., it is engineered for efficient convection heating with a blue flame burner. The thermostat allows precise temperature adjustment and the unit includes a battery for ignition power. Though it does not ship with a blower, this model is often compatible with aftermarket or manufacturer blower kits depending on model year and installation configuration.
Relevance: If you need thermostatic control combined with blue flame convection, this unit is appropriate. Those seeking an integrated blower should confirm blower kit compatibility before ordering.
Buying Guide: Choosing A Natural Gas Wall Heater With Blower
Selecting the right natural gas wall heater involves more than BTU numbers. The following considerations will help you match product capabilities to room needs and installation constraints.
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.
Heat Type: Infrared vs Blue Flame
- Infrared (Radiant) — Warms objects and people directly; quicker perceived warmth in the occupied zone. Best for workshops, garages, or spaces where localized warmth is preferred.
- Blue Flame (Convection) — Heats the air and circulates warm air throughout the room; effective for whole-room comfort and consistent temperatures.
Blower / Fan Considerations
- Integrated Or Add-On — Some heaters include blower kits or are compatible with manufacturer blower accessories. Blowers improve air circulation and can speed warm-up times.
- Compatibility — Confirm model year and compatibility for blower kits (some kits only fit specific models or production dates).
BTU Rating And Room Size
- Choose a unit with appropriate BTU capacity for the square footage and room insulation. Over-sizing may cause short cycling; under-sizing will lead to insufficient heat.
- As a rough guideline, 20,000–30,000 BTU covers many 700–1,400 sq. ft. situations depending on insulation, ceiling height, and climate.
Ignition Type And Power Requirements
- Piezo Or Manual Ignition — No electricity required; useful for power outages.
- Electric Ignition / Battery-Assisted — Requires a small electrical supply (battery or mains) but delivers easier startup and reliable thermostat control.
Safety Features
- Oxygen Depletion Sensor (ODS) — Shuts the unit off if oxygen levels drop; commonly standard on ventless gas heaters.
- Thermostat And Tip-Over Protections — Useful for maintaining setpoint and preventing overheating.
Installation And Venting
- Ventless (Vent-Free) — Easier installation; requires adequate room ventilation and adherence to local codes.
- Local Codes — Confirm building codes, permits, and fuel type restrictions (some locales restrict vent-free heaters).
- Professional Installation — Gas appliance installation should be performed or inspected by a qualified technician.
Efficiency And Fuel Use
- Blue flame heaters tend to offer efficient heat distribution for whole-room heating, while infrared models can be very efficient for targeted comfort.
- Check manufacturer specs for fuel consumption and BTU-to-area guidance.
Maintenance And Longevity
- Routine checks: burner ports, pilot/ignition components, and ODS sensor functionality.
- Follow manufacturer recommended cleaning intervals and annual safety inspections.
Comparison Perspectives
- Performance vs Distribution — If even whole-room warmth is the priority, pair a blue flame heater with a blower. For quick localized warmth, infrared models suffice.
- Power Independence — Non-electric units (piezo ignition) remain functional during outages; electric ignition models provide thermostat convenience but need a small power source.
- Safety and Local Code Compliance — Vent-free heaters require proper ventilation and code compliance; prioritize models with ODS and reliable ignition systems.
