Dyna-Glo IR30PMDG-1 Liquid Propane Infrared

This vent-free infrared wall heater is specified for liquid propane operation and delivers 6,000–30,000 BTU/hr with variable output. Infrared technology radiates heat to objects first, producing a sun-like warmth rather than relying solely on air convection. The manufacturer states coverage up to 1,000 sq. ft. and notes that fuel conversion is not permitted, so it requires the proper LP setup at installation. As an infrared unit, it is often recommended for spaces where direct radiant comfort is preferred over rapid air warming.
ProCom ML300TBA-B Ventless Blue Flame Heater

The ProCom ML300TBA-B is a ventless blue flame heater designed to provide up to 30,000 BTU from liquid propane and is rated to heat areas up to 1,400 sq. ft. This model features thermostat control with High/Medium/Low settings for adjustable comfort and includes both wall mount hardware and base feet for floor placement. The slim profile supports mounting flexibility, and the design emphasizes continuous convection heating, which warms room air similar to central systems.
Mr. Heater 30,000 BTU Radiant Propane Heater

This vent-free radiant model from Mr. Heater delivers 30,000 BTU with advanced infrared burner tiles meant to warm objects and occupants directly. The product claims high efficiency and a fuel consumption rate that offers extended runtime on typical LP cylinders. It is positioned for use in cold rooms, additions, sunrooms, and cabins and highlights radiant warmth that often feels more comfortable for stationary activities compared with convective-only heaters.
Heatstar 30,000 BTU Vent Free Radiant With Blower

The Heatstar radiant unit pairs a top-mounted adjustable thermostat with a built-in blower for improved heat distribution. It uses battery-operated electronic ignition and can be wall mounted or used free-standing with the included feet kit. Features emphasize easy installation, thermostat comfort control, and a blower to move warmed air into the space, making it suitable for localized supplemental heating where both radiant and circulated heat are desired.
Mr. Heater F299730 30,000 BTU Blue Flame Heater

This blue flame vent-free model provides up to 30,000 BTU and is rated for rooms up to 1,000 sq. ft. It features a thermostat for temperature regulation, battery-powered electronic ignition, and an automatic low-oxygen shut-off system (ODS) for added safety. The manufacturer highlights CSA certification and suitability for indoor applications including workspaces, garages, and living areas where efficient convective heating and safety controls are priorities.
Buying Guide: How To Choose A 30,000 BTU Propane Heater
Selecting the appropriate 30,000 BTU propane heater depends on multiple factors: heating technology, room size, installation constraints, control options, and safety certifications. This guide outlines the primary considerations and compares different perspectives to help identify the best fit for your needs.
Heating Technology: Radiant vs Blue Flame
Radiant (Infrared) heaters emit heat that warms objects and people directly. They are effective in spaces where occupants remain stationary, like workshops, sunrooms, or seating areas. Radiant models often feel “warmer” at lower air temperatures because they heat surfaces first.
Blue Flame (Convection) heaters heat the air by convecting warmed air through the room. They tend to provide more uniform ambient temperatures and are commonly used where whole-room comfort is desired. Blue flame units can be better for open areas and spaces with moving occupants.
Coverage And BTU Output
Although models are rated at 30,000 BTU, coverage depends on insulation, ceiling height, layout, and local climate. Typical manufacturer guidance ranges from ~1,000 to 1,400 sq. ft. for these units. Use conservative estimates for poorly insulated spaces and verify local codes for installation requirements.
Vent-Free Considerations
Vent-free (ventless) heaters are designed to operate without a chimney or vent. They release combustion byproducts into the room at very low levels when functioning properly. Look for models with oxygen depletion sensors (ODS) and certification (CSA or equivalent) to address indoor air quality and safety. Maintain adequate ventilation per manufacturer instructions.
Controls And Convenience
Thermostat control provides automated temperature regulation and typically improves comfort and fuel efficiency. Manual three-position controls are simpler but may require more user attention. Electronic ignition (battery or piezo) simplifies starting compared to standing pilot systems. A blower can help circulate heated air for more uniform temperatures.
Installation And Mounting Options
Consider whether you need wall-mounted or free-standing installation. Many models offer both wall mounting and base feet for floor placement. Verify clearances to combustibles, gas supply type (liquid propane), and whether fuel conversion is allowed; some units are locked to LP and cannot be converted.
Fuel Consumption And Runtime
Fuel consumption varies by model and output level. Some manufacturers list pounds-per-hour or runtime on a standard cylinder. If runtime matters, compare fuel consumption rates and plan for appropriate LP cylinder size and refill logistics.
Safety Features And Certifications
Key safety features include ODS (oxygen depletion sensor), automatic shutoff, and CSA or ANSI certification. Electronic ignition reduces pilot-related fuel use and can improve safety. Verify elevation ratings if you live at high altitude as performance and certification may vary with elevation.
Maintenance And Durability
Regular maintenance includes checking burners, cleaning air passages, and following the manufacturer’s inspection schedule. Radiant tiles and blue flame burners have different wear characteristics—ensure replacement parts and service documentation are available for the chosen model.
Comparison Perspectives
- Energy Efficiency: Radiant units can feel warmer at lower thermostat settings, potentially saving fuel when occupants stay in one area. Blue flame units provide more even whole-room heat.
- Comfort Preference: Choose radiant for direct, sun-like warmth; choose blue flame for consistent ambient air temperature.
- Room Use: For workshops, garages, and seating zones, radiant is often preferred. For living rooms and open-plan areas, blue flame or radiant with a blower may be better.
- Installation Limits: If you need mounting flexibility or a blower, confirm those features. Some units require a minimum cylinder size or specific clearances.
Questions To Ask Before Buying
- What is the effective coverage area based on my insulation and layout?
- Does the unit require a minimum LP cylinder size or special regulator?
- Is an oxygen depletion sensor and CSA certification included?
- Do I prefer radiant warmth or convective (blue flame) heating?
- Will the heater be wall-mounted or free-standing and do clearances allow that?
Matching heater technology, control features, safety certifications, and installation constraints to your specific space will help ensure the selected 30,000 BTU propane heater meets heating performance and safety expectations. Review manufacturer manuals and local codes before installation, and consider professional installation for gas connections and vent-free compliance.
