Mr. Heater Portable Buddy Heater
This compact propane radiant heater provides adjustable output from 4,000 to 9,000 BTUs and is designed to heat up to about 225 sq. ft. Its infrared technology heats objects and people directly rather than warming air, which is efficient for close-range outdoor use. The unit includes a durable Piezo igniter for matchless start-up and an improved tip-over safety switch that audibly engages if disturbed.
Considerations include its focus on close-range radiant warmth rather than large-area coverage. The portability and safety features make it suitable for patios where guests sit near the unit or for portable scenarios such as camping and workshops.
Amazon Basics 46,000 BTU Patio Heater
Built for broader outdoor coverage, this slate-gray patio heater produces 46,000 BTUs and claims heat reach of roughly a 9-foot radius. It features a one-touch ignition button and caster wheels for maneuverability, making it practical for both residential patios and small commercial spaces like cafés.

Its design centers on a standing tower with a top reflector to disperse heat. This model emphasizes ease of use and mobility, appropriate for users who need an upright heater that can be moved and started quickly without complex hookups.
Mr. Heater Portable LP Heater 3-Setting
This model offers three heat settings—4,000, 9,000, and 18,000 BTU—providing flexibility from small to medium coverage up to about 450 sq. ft. It supports connection to larger propane tanks (up to 40 lbs) with an accessory hose and filter, which extends runtime for longer outdoor events.
Safety is addressed through automatic shutoff on tip-over and a piezo start. The single control knob simplifies operation. This unit is useful where variable output or longer run times from larger cylinders are required, bridging portable and semi-permanent use cases.
EAST OAK 50,000 BTU Patio Heater
Designed for larger outdoor areas, this unit delivers 50,000 BTUs and spreads heat across a wide diameter. It uses a double-layer 304 stainless steel heating mesh intended to increase durability and life, and it carries ETL certification for safety compliance in commercial and residential environments.

Assembly is described as straightforward with reflector pieces and preassembled segments. Wheels are included for mobility. The emphasis is on high output, durable materials, and certification, which suits venues and homeowners seeking substantial coverage and a robust build.
Heat Hog 18,000 BTU Portable Radiant Heater
Offering up to 18,000 BTUs, this portable radiant heater heats up to 450 sq. ft. depending on setup and fuel source. It features a tiltable design to direct warmth and a curved plaque technology that broadens the heated area. It runs on 1 lb. cylinders or a 20 lb. tank with an accessory hose.
The Heat Hog emphasizes directed radiant heating and portability, making it suitable for garages, RVs, and outdoor spots where a focused warm zone is preferred. The tiltable head and compatibility with multiple cylinder types provide operational flexibility.
Buying Guide: Choosing The Right Propane Outdoor Space Heater
Heat Output And Coverage
BTU rating directly relates to potential coverage area but is affected by outdoor conditions. Higher BTUs (40,000–50,000) are better for open patios and commercial spaces; lower BTUs (4,000–18,000) provide effective close-range or directed radiant warmth. Consider whether you need a broad ambient effect or a focused heat zone.
Radiant Vs. Convective Heating
Radiant heaters warm objects and people directly and are efficient in windy or open spaces where heating air is ineffective. Convective or tower heaters can create a more ambient warmth but may lose efficiency outdoors. Match technology to how you use the space.
Portability And Fuel Options
Decide between truly portable tabletop or buddy-style units that use 1 lb. cylinders and larger standing patio heaters that attach to 20 lb. or 40 lb. tanks. Portable units favor transient use (camping, tailgates); larger tanks support longer gatherings without frequent cylinder changes.
Safety Features
Look for tip-over shutoff, flame failure devices, oxygen depletion sensors (if advertised), and sturdy bases. ETL or CSA certification is an indicator of third-party testing. For terraces and balconies, check local codes for permitted heater types.
Mobility, Assembly, And Maintenance
Wheels and a lighter assembly reduce setup time when moving units between storage and use. Stainless steel and tempered glass resist corrosion outdoors. Consider how easy it is to clean burners, replace parts, and access valves for winter storage.
Noise, Ignition, And Controls
Piezo ignition and one-touch starters simplify use; electronic ignitions may need power. Check for adjustable control knobs for variable heat and how audible safety switches are in case of tip-over or low flame conditions.
Installation And Placement Considerations
Maintain recommended clearances from walls, overhangs, and furniture. Permanent or semi-permanent installations may require professional help. Consider wind patterns, as drafts reduce effective coverage and may extinguish flames on some models.
Performance In Different Weather
Wind, ambient temperature, and humidity affect performance. Radiant heaters are less impacted by wind than convective models. For colder climates, choose higher BTU units or multiple units spaced appropriately for consistent comfort.
Cost Of Ownership And Accessories
Factor in cylinder replacement, hose and regulator accessories, covers for storage, and replacement parts. Larger tanks lower the frequency of cylinder swaps but add installation considerations. Certified covers extend product life by protecting components.
