No product in this list is a 500 BTU propane heater: the listed models produce 20,000 or 25,000 BTU per hour. They are higher-output options for buyers who need substantially more heat. The ProCom manual-control model is best for straightforward settings, while its thermostat version offers thermostat control. Mr. Heater’s radiant and blue-flame models provide two different heater styles. Compare the output carefully before choosing; none is a match if you specifically require a 500 BTU unit.
| Product | Listed Output | Best For |
|---|---|---|
| ProCom Blue Flame, Manual | 20,000 BTU | Simple manual heat settings |
| Mr. Heater Radiant Dual Fuel | 20,000 BTU | Radiant-style heating |
| ProCom Blue Flame, Thermostat | 20,000 BTU | Thermostat control and placement options |
| ProCom Infrared Plaque | 25,000 BTU | Higher listed output |
| Mr. Heater Blue Flame Dual Fuel | 20,000 BTU | Blue-flame heating with electronic ignition |
ProCom 20,000 BTU Blue Flame Heater
This ProCom model is best for buyers who want a propane-only heater with direct manual settings. Its listed maximum output is 20,000 BTU, and the product information says it can heat up to 950 square feet. That output is far above 500 BTU, so it is not suitable for someone who needs to stay near that lower capacity.
- Uses liquid propane and does not require electricity.
- Push-button Piezo ignition and three manual heat settings: low, medium, and high.
- Includes an Oxygen Depletion Sensor with automatic shut-off.
Choose this if simple controls matter more than thermostat operation. A limitation is that its listed fuel is propane only, rather than dual fuel.
Mr. Heater 20,000 BTU Radiant Dual Fuel Heater
This Mr. Heater is best for shoppers seeking a radiant-style heater and a dual-fuel design. Its listed output is 20,000 BTU per hour, with coverage stated as up to 700 square feet. These specifications make it a higher-capacity option, not a 500 BTU alternative.
- Radiant, vent-free heater design.
- Dual-fuel operation, as stated in the product name.
- Battery-operated electronic spark ignition.
Choose this if radiant heating and electronic ignition align with your needs. The listed coverage is lower than the 950-square-foot claims for the two 20,000 BTU ProCom blue-flame models, so compare the stated coverage as well as output.
ProCom Blue Flame Heater With Thermostat
This ProCom is best for buyers who prefer thermostat control and want the choice of floor or wall placement. It produces up to 20,000 BTU using liquid propane, and the listing says it can heat up to 950 square feet. It is not a low-output 500 BTU heater.
- Thermostat control with high, medium, and low settings.
- Includes base feet for floor placement and hardware for wall mounting.
- Slim profile described in the product information.
Choose this over the manual ProCom model if thermostat control and mounting flexibility matter. A limitation is that it is listed for liquid propane, not as a dual-fuel model.
ProCom 25,000 BTU Infrared Plaque Heater
This ProCom model is best for buyers comparing the highest listed output in this group. Its infrared plaque design produces up to 25,000 BTU using liquid propane, and the stated coverage is up to 1,150 square feet. That output is 50 times the 500 BTU figure in the search phrase.
- Thermostat control with high, medium, and low settings.
- Includes base feet and wall-mounting hardware.
- Designed for floor or wall placement, according to the listing.
Choose this if you need more listed output than the 20,000 BTU options. Avoid it if your requirement is specifically a 500 BTU appliance or a lower-output heater.
Mr. Heater 20,000 BTU Blue Flame Heater
This Mr. Heater is best for buyers seeking a blue-flame heater with electronic spark ignition. The listing gives an output of 20,000 BTU per hour and coverage of up to 700 square feet. It is another substantially higher-output product rather than a 500 BTU match.
- Vent-free blue-flame design.
- Dual-fuel operation, as stated in the product name.
- Battery-operated electronic spark ignition; the listing says a battery is included.
Choose this over the radiant Mr. Heater if you specifically want the blue-flame style. The stated coverage is up to 700 square feet, so compare it with the larger coverage claims of the ProCom models.
Buying Guide: How to Choose a Propane Heater
Do you actually need 500 BTU?
Check whether 500 BTU is a strict equipment requirement or an approximate search term. Every product here is rated at least 20,000 BTU per hour. If you need a heater close to 500 BTU, these models are not appropriate; look for a product whose specifications clearly match your required output.
How much heat output and coverage do you need?
Compare both BTU output and the manufacturer-listed coverage. In this group, the 20,000 BTU products list coverage from 700 to 950 square feet, while the 25,000 BTU ProCom lists up to 1,150 square feet. Treat coverage as a product claim, not a guarantee for every room; actual needs can vary with the space and conditions.
Which heater style and controls fit your priorities?
The listed choices include blue-flame, radiant, and infrared plaque designs. For controls, the manual ProCom offers low, medium, and high settings, while the thermostat-controlled ProCom models add thermostat operation. The Mr. Heater listings specify battery-operated electronic spark ignition; one states that a battery is included.
What should you check before buying?
Confirm the fuel type, installation options, and instructions for the specific model. Some products are described as propane-only, while the Mr. Heater models are described as dual fuel. Follow the manufacturer’s directions and check local requirements for vent-free propane heaters before selecting an indoor location.
