Comfort Glow 11,000 BTU Direct Vent Wall Heater
Type: Direct vent liquid propane wall heater. Primary Use: Small to medium rooms, additions, or finished garages where sealed combustion is preferred.
This model delivers 11,000 BTU and is rated to heat up to about 375 sq. ft. The unit features a sealed burn system and Matchless Piezo Ignition, reducing indoor combustion exposure by drawing air from outside and exhausting combustion gases directly outdoors. A built-in pressure regulator and safety pilot help stop gas flow if the pilot extinguishes. The wall-mount design is compact and suitable for rooms where venting to the exterior is possible and desired.
Comfort Glow 17,000 BTU Direct Vent Wall Heater
Type: Direct vent liquid propane wall heater. Primary Use: Larger rooms or small open-plan areas.

This larger direct-vent unit provides 17,000 BTU, with manufacturer coverage up to about 570 sq. ft. It uses the same sealed combustion approach as the smaller Comfort Glow, improving indoor air quality by keeping combustion isolated. The integrated safety pilot and pressure regulation add protection against unintended gas flow. The wider cabinet suits larger wall openings and can serve as a primary supplemental heater where venting through an exterior wall is feasible.
Dyna-Glo 30,000 BTU Blue Flame Vent Free Wall Heater
Type: Vent-free blue flame propane heater. Primary Use: Large rooms where venting is not available and local codes allow vent-free appliances.
This wall-mounted blue flame model offers variable output from 24,000 to 30,000 BTU and is designed to convect heat to the room air. Because it is vent-free, combustion products are released indoors and rely on proper room size and ventilation for safe operation. The unit is intended for spaces up to around 1,000 sq. ft. Note that vent-free units must be used in accordance with local building codes and room size requirements to maintain safe oxygen and combustion byproduct levels.
Mr. Heater 30,000 BTU Vent Free Radiant Propane Heater
Type: Vent-free radiant infrared propane heater. Primary Use: Supplemental heating for large rooms, sunrooms, or cabins where radiant warmth is preferred.

This model uses infrared/radiant technology with multiple burner tiles to warm objects and people directly, offering a different warmth feel than convection units. Rated at 30,000 BTU, it targets up to about 1,000 sq. ft. Vent-free radiant units provide efficient perceived warmth but emit combustion products indoors. Safety features and adherence to local regulations are critical when selecting a vent-free heater for indoor use.
Dyna-Glo IR30PMDG-1 30,000 BTU Infrared Vent Free Heater
Type: Vent-free infrared/infrared-style propane heater. Primary Use: Areas where direct radiant heat is desired without a vent system available.
This Dyna-Glo model offers variable BTU from 6,000 to 30,000, allowing modulation of output to match room demand. Infrared heating warms objects and occupants first, which can feel more immediate than air heating. As a vent-free appliance, it is suitable only where regulations allow and where users can ensure adequate room volume and ventilation for safe combustion byproduct dilution.
Buying Guide: How To Choose A Propane Indoor Vented Heater
Vented vs. Vent-Free: Direct vent (vented) heaters use sealed combustion chambers and an external vent to exhaust combustion gases, preserving indoor air quality. Vent-free
Room Size And BTU Capacity: Calculate room heating needs by square footage, insulation level, and ceiling height. Smaller direct-vent units (10k–17k BTU) suit bedrooms and small living areas; larger units (24k–30k BTU) address bigger or open spaces. Allow margin for cold climates and poor insulation.
Sealed Combustion And Safety Features: For vented units, prioritize sealed combustion chambers, pressure regulators, and reliable ignition systems. For vent-free, look for Oxygen Depletion Sensors (ODS)
Installation Requirements: Direct-vent models require an exterior wall or vent path for intake and exhaust. Confirm clearances, venting kit compatibility, and whether professional installation or permits are needed. Vent-free units typically need only wall-mounting clearances but verify local code.
Combustion Type — Blue Flame Vs. Infrared: Blue flame (convective) heaters warm air, distributing heat through convection. Infrared/radiant heaters warm people and objects directly, often feeling warmer at lower air temperatures. Choose based on occupant comfort preferences and room use.
Controls And Thermostats: Built-in thermostats and variable output improve comfort and fuel efficiency. Battery-powered electronic ignition minimizes pilot flame fuel use. Consider units offering precise temperature control if the heater will operate as a primary heat source.
Fuel Consumption And Cylinder Requirements: Check fuel consumption rates (lbs/hr) and recommended propane cylinder size. Larger BTU units use more fuel and may require a permanently plumbed supply or frequent cylinder changes.
Local Codes And Permits: Confirm local building codes and restrictions on vent-free appliances. Many jurisdictions restrict vent-free units in bedrooms, bathrooms, or small enclosed areas. Direct vent units are more widely accepted for indoor use.
Maintenance And Service: Regular inspection of burners, combustion chambers, vents, and controls ensures safe long-term operation. Sealed vent systems require periodic vent inspection for blockages or leaks. Follow manufacturer service intervals.
Noise And Drafts: Direct vent systems may include small fans or coaxial piping that can affect installation complexity. Radiant units typically operate quietly but consider any blower options if rapid heat distribution is desired.
Comparison Perspectives: Evaluate units by safety (sealed combustion, ODS), efficiency (BTU vs. room size), comfort type (convective vs. radiant), and installation feasibility (vent path vs. wall clearance). Direct vent models score higher for indoor air quality; vent-free models score higher for ease of installation where codes permit.
