CAMPLUX advertises adjustable output at 6,000, 12,000, and 18,000 BTU. The heater connects to a standard 20 lb propane tank via the included regulator and hose, and is claimed to warm spaces up to 450 sq. ft.
Key safety features include an oxygen depletion sensor (ODS) and tip-over protection that automatically cut gas if oxygen drops or the unit is knocked over.
No electricity is required for operation. On low output, the manufacturer notes extended runtime, and the control knob allows simple adjustment of heat output for fuel-saving operation or rapid warmth.
Mr Heater 4000 To 18000 BTU Portable LP Gas Heater
Mr Heater’s portable LP heater offers three heat levels—4,000, 9,000, and 18,000 BTU—suitable for campers, porches, sheds, and job sites. The single-control knob and piezo ignition simplify starting the unit.
The unit supports use with larger tanks (up to 40 lbs) when an additional hose and filter are used, which can be useful for extended multi-day operation without tank swaps.

Safety mechanisms include an automatic shutoff if the unit tips. The heater is built to be moved between indoor and outdoor locations if manufacturer-recommended ventilation and clearances are followed.
Mr. Heater Portable Buddy MH9BX
The Portable Buddy MH9BX is a compact radiant propane heater designed for smaller spaces up to 225 sq. ft. It operates between 4,000 and 9,000 BTU, aiming for efficient, localized warmth.
This model highlights improved tip-over safety and a durable piezo igniter for matchless startup. Its radiant heating method warms objects and people directly, rather than heating large volumes of air.
The Buddy series is frequently used in campers, workshops, and emergency indoor situations where a small, controllable heat source is required and ventilation is adequate.
Avenger FBDTP30 Infra-Red Tank Top Outdoor Heater
The Avenger FBDTP30 is a tank-top, double-burner infrared heater offering up to 30,000 BTU and directional heating by swiveling burner heads up to 45 degrees.
Designed primarily for outdoor use, the unit hooks onto a propane tank and features a safety control valve that stops gas flow if the flame goes out. It uses match-light ignition and includes a tip switch for automatic shutdown if overturned.
This configuration offers robust, focused heat for camping areas, open patios, and larger outdoor gatherings where high output and directional warmth are required.
Buying Guide
This buying guide highlights essential considerations when selecting a propane radiator heater for indoor or outdoor use. Assess each item below against your intended use case for safe, effective heating.
Heat Output And Coverage
- BTU Ratings: Higher BTU delivers more heat but uses more fuel. Small spaces often require 4,000–9,000 BTU, while larger areas may need 18,000 BTU or above.
- Coverage Area: Manufacturers usually state a square-foot range; match that to the space you intend to heat and account for ventilation losses.
Safety Features
- Tip-Over Shutoff: Essential for portable units; this feature cuts gas if the heater is knocked over.
- Oxygen Depletion Sensor (ODS): Recommended for indoor use; it shuts off the unit if ambient oxygen falls below safe levels.
- Automatic Flame Control: Protects against gas leaks if the pilot or flame extinguishes unexpectedly.
Fuel Connection And Runtime
- Tank Compatibility: Check whether the unit attaches to 20 lb tanks or requires additional hoses for larger tanks.
- Regulator And Hose Included: Units that include a regulator and hose simplify setup; confirm hose length meets your layout needs.
- Runtime Expectations: Lower BTU settings extend runtime. Consider how long you need continuous operation when selecting capacity and connections.
Portability And Installation
- Weight And Handle Design: Look for molded handles or compact footprints for transport and storage.
- Mounting Type: Tank-top heaters mount directly to the tank; others have a freestanding design. Choose based on stability and space.
- Ignition Type: Piezo ignition requires no batteries or matches; match-light models may be less convenient outdoors in windy conditions.
Intended Use: Indoor Vs. Outdoor
- Indoor Use: Prioritize ODS and adequate ventilation. Many units are labeled for indoor-safe use only when used per manufacturer instructions.
- Outdoor Use: Look for weather-resilient designs and directional heating for focused warmth in open spaces.
- Dual Use: If planning both, verify the unit’s certification and safety features for indoor operation and follow clearance and ventilation guidance.
Heating Method And Efficiency
- Radiant vs Forced Air: Radiant heaters heat objects and people directly and are efficient in open settings. Forced-air units move warmth through airflow and can heat larger volumes faster.
- Adjustable Settings: Multiple BTU steps allow balancing comfort and fuel use.
Durability And Maintenance
- Construction Materials: Stainless steel or durable painted finishes resist corrosion in outdoor use.
- Serviceability: Check availability of replacement hoses, regulators, and parts to extend service life.
- Cleaning: Keep vents and protective guards clear of debris for consistent performance.
Comparison Perspectives
- Small Spaces: Choose lower BTU radiant units with strong tip-over and ODS protections for enclosed use.
- Large Outdoor Spaces: Consider tank-top double burners or higher BTU models for directional, high-output heating.
- Long Runtime Needs: Opt for units compatible with larger tanks or those with lower selectable BTU settings to extend runtime.
When selecting a propane radiator heater, weigh output, safety features, fuel setup, and intended environment. Match the heater’s specifications to the space and use-case for safe and effective warmth.
