Mr. Heater MHVFBF20LPT 20,000 BTU Blue Flame Vent Free Propane Heater
This wall-mounted vent-free model provides up to 20,000 BTU and is designed to heat rooms up to about 700 sq. ft. It uses a blue flame convective method to warm air in the space, and it includes a thermostat plus a battery-powered electronic ignition for straightforward startup.
Safety features include an Oxygen Depletion Sensor (ODS) that automatically shuts the unit off if oxygen levels drop. The heater is rated for reliable performance up to elevations of 4,500 ft. and lists a fuel consumption rate for planning run time.
As a wall-mounted vent-free heater, it does not include an integrated forced-air fan, but pairing this unit with a circulating fan or a heat-powered stove fan can help distribute convective heat more evenly across adjacent rooms.

This thermoelectric heat-powered fan is designed to sit on hot surfaces and convert thermal energy into fan rotation, requiring no batteries or electricity. It can be fixed to Buddy-style heaters or placed on compatible hot surfaces with the included bracket.
Included features list a magnetic stove thermometer that monitors surface temperature and a stable bracket for secure attachment. The product is positioned for use with propane Buddy heaters, fireplaces, and small stoves to improve heat circulation in tents, workshops, and cabins.
Because it operates when a surface reaches operating temperature, the fan helps move radiant and convective heat into the room rather than relying solely on heat rising naturally from the heater body.
Dyna-Glo IR30PMDG-1 30,000 BTU Liquid Propane Infrared Vent Free Wall Heater
This vent-free infrared model uses radiant heat to warm objects and people directly, similar to sunlight, rather than primarily heating the air. It offers a variable output from 6,000 to 30,000 BTU to cover spaces up to approximately 1,000 sq. ft.
The unit is specified as liquid propane ready and emphasizes direct radiant warming, which can feel more immediate in cooler environments. Like other vent-free heaters, it does not incorporate a fan, but radiant heating paired with a small circulation fan can improve perceived warmth across an area.

Infrared units are often chosen where targeted, fast warmth is preferred; adding a compatible fan or a passive thermoelectric fan nearby helps move warmed air gently without changing the unit’s operating characteristics.
Mr. Heater 18,000 BTU Big Buddy Pro Series Portable Propane Heater
The Big Buddy Pro is a portable radiant propane heater with adjustable settings from 4,000 to 18,000 BTU, suitable for indoor/outdoor use and spaces up to about 450 sq. ft. It’s designed to be nearly 100% efficient in turning fuel into warmth.
Safety systems include automatic shut-off for tip-over, pilot outage, and low-oxygen conditions. The heater’s radiant output directly warms nearby objects and people; pairing it with a heat-powered fan or a small electric fan helps spread warmth into the surrounding space more uniformly.
For camping, job sites, and workshops, this model’s portability and compatibility with heat-fan accessories make it a practical option where forced-air distribution is needed but an integrated fan is not provided.
Mr. Heater 4000 To 18000 BTU Dual Tank Portable LP Gas Heater
This variable-setting portable propane heater provides 4,000, 9,000, or 18,000 BTU options and supports a dual-tank connection for extended run time with larger tanks. It’s intended for porches, sheds, and similar semi-enclosed areas.
The unit uses radiant heating and includes a simple single-control knob with piezo ignition and safety shutoffs including tip-over protection. While it does not contain a built-in fan, its compatibility with external fans or thermoelectric heat fans enables improved heat distribution when needed.
Users who need flexible tank options and multiple heat settings often pair this model with an accessory fan if faster room air circulation is desired.
Buying Guide: Choosing A Propane Heater With The Right Fan Solution
Selecting the right combination of propane heater and fan involves assessing space, heater type, safety, and fan compatibility. The following considerations help match performance to needs.
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

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.
Heater Type And Heat Distribution
- Radiant Heaters (Buddy, Big Buddy, portable tank units) warm people and objects directly. Use a circulating fan or thermoelectric stove fan to push warmed air further into the room.
- Blue Flame / Convective Vent-Free Heaters warm air that then circulates naturally. These are effective for whole-room heating; pairing with a small fan accelerates even distribution.
- Infrared Heaters deliver immediate perceptible warmth; combine with a fan if you need the heat to move beyond the direct line of sight.
Fan Types And Compatibility
- Thermoelectric (Heat-Powered) Fans operate without electricity by sitting on a hot surface. Ideal for wood stoves and some portable heaters that provide a flat hot area. They are silent and self-powered but require a minimum surface temperature to run.
- Electric Fans (small circulation fans) can be used near vent-free wall or portable heaters to move air actively. Ensure placement meets safety clearances and local codes about proximity to heaters.
- Integrated Fans are uncommon in vent-free propane heaters due to safety and venting concerns; most solutions are external accessories.
Safety Features To Prioritize
- Oxygen Depletion Sensor (ODS): Essential for indoor vent-free units to shut down if oxygen is low.
- Tip-Over Switch: Critical for portable units used in garages, workshops, or outdoor settings.
- Certified Installation: Wall-mounted vent-free heaters should be installed per manufacturer guidance and local codes; fan placement must not obstruct safety devices.
Space Size And BTU Matching
- Estimate the square footage and ceiling height to select a heater with appropriate BTU output. Radiant BTU requirements differ from convective units since radiant heat is perceived differently.
- For larger or open spaces, choose higher BTU units and pair with fans to distribute heat across more volume.
Fuel And Run Time Considerations
- Check the fuel consumption rate and compare with your tank capacity or dual-tank setup to estimate run time.
- Dual-tank connections extend operation and can be useful for long outdoor events or workshops.
Installation And Maintenance
- Follow manufacturer instructions when mounting wall heaters and maintain clearances for air flow and fan placement.
- Regularly inspect thermoelectric fans for a secure fit and clean blades to maintain performance.
- Test safety features periodically, especially ODS and tip-over switches.
Comparison Perspectives
- Portability vs. Permanent Installation: Portable Buddy-style heaters excel for flexible use; wall-mounted vent-free units provide a more permanent whole-room solution.
- Immediate Warmth vs. Whole-Room Comfort: Infrared and radiant units deliver quick, localized warmth; convective blue flame units tend to provide steadier whole-room temperatures when paired with circulation fans.
- Self-Powered Fans vs. Electric Fans: Thermoelectric fans add heat distribution without wiring or batteries, but require a hot contact surface; electric fans offer continuous control but need power and proper placement.
