8 Best Portable Propane Heaters With Thermostat 2025 in the United States

The Heatstar 30000 Btu Vent Free Radiant Propane Heater with Thermostat and Blower offers a substantial heat output of 30,000 BTU, making it suitable for larger spaces. The adjustable top-mounted thermostat control is convenient for maintaining desired temperatures without constant manual adjustments. Safety is a priority with a built-in low oxygen sensor, which is a crucial feature for indoor propane heaters.

The portability of this unit is enhanced by the option to wall mount or use the included feet kit for free-standing placement. However, at just 1 pound, it might be prone to tipping if not secured properly when used free-standing. This heater is also practical during power outages since it can operate without electricity, though the blower requires power for optimal performance.

The battery-operated electronic ignition (with one AA battery included) simplifies the lighting process. In terms of fuel consumption, propane heaters generally provide a cost-effective heating solution, although specific consumption rates are not detailed here.

The Mr. Heater MHVFRD20LPT is a solid choice for those seeking a portable propane heater, especially for cold rooms, sunrooms, or cabins. With an impressive BTU rating of 18,000, it efficiently warms spaces up to 700 square feet. Its radiant heating technology mimics the warmth of the sun, creating a cozy atmosphere. One of the standout features is its built-in thermostat, allowing you to control the temperature easily, which is great for maintaining comfort without constant adjustments.

Fuel consumption is another strong point; it uses only about 0.926 lbs of propane per hour, providing up to 21.59 hours of warmth from a standard 20 lb cylinder. This means you won’t have to refill your fuel supply too often, making it convenient for extended use. Additionally, the battery-powered electronic ignition allows for quick startup, which is incredibly user-friendly.

Safety is a top priority with this heater as well. The automatic shut-off feature activates if oxygen levels drop, ensuring peace of mind while using it indoors. This makes it a reliable option for people who may have safety concerns with propane heaters. However, the heater does come with some drawbacks. While it is portable, being wall-mounted might not suit everyone’s space requirements. Additionally, it’s essential to note that it’s designed for indoor use but lacks a venting system, which might raise air quality concerns in poorly ventilated spaces.

The ProCom ML100TPA-B is a compact and efficient propane heater, ideal for heating spaces up to 500 square feet. With a 10,000 BTU rating, it provides ample heat for small areas like bedrooms, home offices, and living rooms. The built-in thermostat offers three control settings (High/Medium/Low), allowing you to adjust the temperature based on your comfort needs. This feature is particularly beneficial for maintaining a consistently warm environment without excessive fuel consumption. Additionally, it does not require electricity, making it a reliable option during power outages or emergencies.

The heater includes both wall mount hardware and base feet, offering versatile placement options to suit different room layouts. Safety is a priority with the ProCom ML100TPA-B, as it comes with an oxygen depletion sensor (ODS) that automatically shuts off the heater if it detects low oxygen levels or carbon monoxide, ensuring user safety. The push-button ignition system simplifies the start-up process, making it user-friendly even for those not tech-savvy.

On the downside, the heater's white color may not blend well with all interior decors, and its modern slim profile might be too plain for some aesthetic tastes. At 16.87 pounds, it is relatively lightweight, but still might require some effort to move around frequently. The ProCom ML100TPA-B offers a blend of efficiency, safety, and convenience, making it a solid choice for those needing a portable propane heater with thermostat control.
