Mr. Heater 20,000 BTU Blue Flame
This vent-free blue flame wall heater produces up to 20,000 BTUs, suitable for cabins and rooms up to about 700 sq. ft. It includes a thermostat for temperature control and a battery-powered electronic ignition for easy startup (battery included). The unit is designed to operate reliably at elevations up to 4,500 ft. Safety features include a factory-standard Oxygen Depletion Sensor (ODS) that shuts the heater off if oxygen levels drop. Fuel consumption is listed at about 0.926 lbs/hr, which can help estimate run times from a standard propane cylinder. Installation is wall-mounted and intended for indoor use where vent-free appliances are permitted.
Mr. Heater Portable Buddy MH9BX
The Portable Buddy MH9BX is an infrared radiant heater offering 4,000–9,000 BTUs, ideal for small cabins, workshops, or single rooms up to around 225 sq. ft. Infrared technology heats objects and people directly rather than warming the air first, which can feel quicker in drafty or intermittently used spaces. Safety enhancements include an improved tip-over switch and a robust Piezo igniter that requires no batteries. The unit is designed as an indoor-safe propane radiant heater and is commonly used for temporary or supplemental heating where portability and quick warmth are priorities.

This vent-free radiant wall heater delivers 30,000 BTUs of infrared-style heat intended for areas up to about 1,000 sq. ft. It uses multiple burner tiles to produce sun-like warmth and emphasizes high efficiency and fuel economy. The heater reports fuel consumption around 1.389 lbs/hr at full output, with a runtime calculation provided for a standard LP cylinder. It is intended as a supplemental or primary heater for larger cabins and sunrooms where distributed radiant warmth is preferred.
Mr. Heater 30,000 BTU Blue Flame
The F299730 is a vent-free blue flame wall heater rated at 30,000 BTUs, suitable for cabins up to roughly 1,000 sq. ft. It features a thermostat-controlled operation and battery-powered electronic ignition for straightforward use. Safety systems include an automatic ODS and CSA certification for compliance with applicable safety standards. This model is designed for consistent performance at elevations up to 4,500 ft, making it suitable for many mountain cabins where ambient pressure varies.
Mr. Heater 18,000 BTU Radiant Heater
This vent-free radiant wall heater produces 18,000 BTUs, suitable for areas up to about 700 sq. ft. It emphasizes fuel efficiency, consuming approximately 0.926 lbs/hr, and is intended to run longer on a given propane supply compared to higher-BTU models. Infrared-style heating tiles deliver targeted warmth to people and objects, which can be efficient for cabins with irregular occupancy. It requires a minimum 20 lb LP cylinder for optimal performance and mounts to the wall for permanent or semi-permanent installation.
Buying Guide: Choosing A Propane Heater For A Cabin
When selecting a propane heater for a cabin, consider the following objective factors to match the heater to your space and use case.

Heat Output And Coverage
- BTU Rating: Higher BTUs heat larger spaces. Estimate needs by square footage, building insulation, and typical outdoor temperature. Vent-free blue flame and radiant units list approximate coverage—confirm against your cabin size.
- Room Layout: Radiant units warm objects directly and work well for occupied zones; blue flame units heat the air and can be better for whole-room warmth.
Vent-Free vs Radiant vs Portable
- Vent-Free Blue Flame: Efficient at heating air throughout the room, often with thermostatic control; requires adherence to local codes and proper ODS safety systems.
- Radiant Heaters: Use infrared-style heating to warm people and surfaces; effective in drafty or intermittently used spaces and often more fuel-efficient for spot heating.
- Portable Units: Offer flexibility and can be used temporarily; check tip-over protection and indoor safety certification before using as a primary cabin heater.
Safety Features
- Oxygen Depletion Sensor (ODS): Essential for vent-free units; it shuts the unit off if oxygen falls below safe levels.
- Tip-Over Switch: Critical for portable heaters to prevent fires if the unit is knocked over.
- Flame Failure Device & Certifications: Look for CSA or other recognized safety certifications and automatic shutoff features for malfunction scenarios.
Fuel Efficiency And Runtime
- Fuel Consumption: Measured in lbs/hr for propane; lower consumption extends runtime on a standard 20 lb cylinder.
- Thermostatic Control: Heaters with thermostats can cycle to maintain set temperatures and reduce fuel use compared with manual-only controls.
Installation And Venting Regulations
- Local Codes: Vent-free appliance use is subject to state and local regulations—confirm permissibility before installation.
- Mounting Requirements: Wall-mounted units require clearance and fuel line access; portable units require safe placement and stable surfaces.
Altitude And Performance
- High-Altitude Operation: Some heaters specify reliable operation up to certain elevations (e.g., 4,500 ft). If your cabin is at high elevation, verify the heater’s stated elevation performance.
Maintenance And Reliability
- Burner Tile/Orifice Cleaning: Vent-free radiant and blue flame units may need periodic cleaning to maintain efficiency and safe combustion.
- Ignition Systems: Battery-powered electronic ignition vs. Piezo igniters—consider availability of replacement batteries and ease of starting in cold conditions.
Comparison Perspectives
- Cost-To-Operate vs Coverage: Higher-BTU units heat larger spaces but consume more fuel; match capacity to the space to avoid wasted fuel or insufficient warmth.
- Portability vs Permanent Installation: Portable radiant units are suitable for temporary or supplemental heating. Wall-mounted blue flame units are better for consistent primary heating in cabins where vent-free is allowed.
- Safety vs Performance: Choose models with automatic shutoffs and certified safety systems if the cabin may be unattended or used seasonally.
Use the technical specifications—BTUs, fuel consumption, safety features, and listed coverage—along with local code requirements and your cabin’s insulation profile to select the most appropriate propane heater. Professional installation or consultation with local authorities is recommended when installing gas appliances indoors.
