Mr. Heater Portable Buddy MH9BX
This portable radiant heater uses infrared technology to heat people and objects directly. It offers an adjustable output between 4,000 and 9,000 BTU, suitable for areas up to about 225 sq. ft. The unit’s Piezo igniter provides matchless ignition, and the product description highlights an improved tip-over safety switch that audibly engages if the heater is moved or tipped.
Key strengths include focused radiant warmth that feels like “sun-like” heat and easy portability for campers, workshops, and patios. The lack of batteries and simple sparker design simplifies operation. The safety-focused tip-over enhancement is emphasized for safer use in active environments.
Mr. Heater 4000 To 18000
This three-setting portable LP gas heater offers versatility with 4,000, 9,000, and 18,000 BTU outputs and a stated heat range up to 450 sq. ft. It supports connection to larger propane tanks (up to 40 lbs) when used with an additional hose and filter, which is practical for extended outdoor applications.

The model uses a single control knob and a piezo sparking mechanism. Its listed features include an automatic safety shutoff that activates on tip-over. This heater suits users who want variable heat levels and the option to connect to larger tanks for longer run times or higher output.
Mr. Heater MH4B Little Buddy
The Little Buddy is focused on small indoor-safe spaces, delivering 3,800 BTU with coverage suitable for areas up to 95 sq. ft. It includes an oxygen depletion sensor (ODS), patented cross-thread protection, and a tip-over shutoff—features intended for safer use in enclosed spaces like tents or small rooms.
The product lists a runtime of about 5.6 hours at maximum output on a 1-pound cylinder (not included). Rated to operate up to elevations of 7,000 feet, this unit is positioned as a compact solution where indoor-safe certification and low BTU output are key priorities.
15,000 BTU Single Tank Top Heater
This single-burner radiant heater mounts directly to a 20 lb tank for portability and provides selectable regulator settings with 10,000–15,000 BTU options. The product description notes a tip-over safety shut-off and a simple mount-to-tank design for quick setup.

As a tank-mounted radiator, it offers higher output than the smallest portable models while remaining relatively compact. The high-medium-low regulator enables some control over output and fuel consumption, making it suitable for larger porches or outdoor workspaces where a small but powerful heater is needed.
Buyplus Propane Heater 6200BTU
This portable heater lists an output of 6,200 BTU and highlights an electronic ignition and a protective mesh guard that reduces direct contact with heating elements. It is promoted for outdoor uses like camping, fishing, and garage work.
The feature set emphasizes rapid heat, push-button start, and safety via a mesh guard to protect users and prevent foreign object contact. The design targets users wanting a straightforward, mid-range small heater with safety shielding around the burner.
Buying Guide: How To Choose A Small Propane Heater
Choosing the right small propane heater requires matching heater type, safety features, and fuel/runtime needs to your intended use. Below are critical factors to compare before purchase.
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.
1. Heater Type And Heat Delivery
- Radiant vs. Convection: Radiant heaters warm people and objects directly and are efficient for targeted spots (porches, tents). Convection heaters warm air and are better for enclosed areas.
- Tank-Mount vs. Portable Stand: Tank-top heaters mount to the propane cylinder for compactness and higher BTU; portable stand units often offer broader directional coverage and sometimes larger tanks.
2. BTU Output And Coverage
- Match BTU output to space size. Small heaters (3,000–6,000 BTU) suit tents or very small rooms. Mid-range units (6,000–15,000 BTU) cover larger porches and garages. Higher outputs are designed for open outdoor areas.
- Manufacturer square-foot estimates assume certain conditions; insulation, wind, and outdoor exposure reduce effective coverage.
3. Safety Features
- Tip-Over Shutoff: Prevents operation when the unit falls—essential for portable use.
- ODS (Oxygen Depletion Sensor): Required for certified indoor safe units; shuts off when oxygen levels drop.
- Protective Guards: Mesh or grills reduce burn risk from accidental contact.
4. Ignition And Controls
- Piezo Or Electronic Ignition: Piezo igniters work without batteries; electronic ignition can be more convenient but may require power.
- Variable Heat Settings: Multiple settings let you balance heat and runtime.
5. Fuel Source And Runtime
- Confirm the tank size compatibility (1 lb cylinders vs. 20 lb tanks vs. larger tanks). Adapters may be required for larger tanks.
- Estimate runtime at chosen BTU settings. Lower BTU extends runtime but reduces heat output.
6. Portability And Setup
- Consider weight, handle design, and whether the heater mounts directly to a tank for compact transport.
- Check assembly complexity; many small units offer tool-free hookup while some tank-top units require secure mounting.
7. Intended Use And Certification
- Indoor Use: Only use units explicitly rated for indoor or enclosed use and with ODS certification.
- Outdoor Use: Open-area heaters can have higher BTU but lack indoor safety features.
8. Environmental And Site Considerations
- Wind and open-air spaces reduce effectiveness of radiant heaters. Use wind breaks or semi-enclosed areas to improve performance.
- Altitude can impact combustion; verify product elevation ratings for high-altitude use.
9. Maintenance And Parts
- Inspect fittings, hoses, and connectors regularly for leaks or wear. Replace parts as recommended by the manufacturer.
- Clean protective grills and burners periodically to maintain efficient combustion and prevent blockages.
10. Purchase Comparison Perspectives
- Value For Size: Small, low-BTU units offer portability and indoor safety while sacrificing coverage.
- Performance vs. Portability: Tank-top designs deliver more BTU per weight but are less suited to indoor use without proper certification.
- Safety Priority: For enclosed or tent use, prioritize ODS and tip-over sensors over raw BTU output.
