10 Best Propane Heaters 2026 in the United States

The ProCom ML100TBA-B is a ventless propane heater designed for indoor use in spaces up to 500 square feet, offering a 10,000 BTU heat output, which is suitable for bedrooms, home offices, or small living areas. Its compact size and modern look make it easy to fit in most rooms, and it can be placed on the floor or mounted on a wall, adding flexibility in how you use it.

One of its strong points is safety: it includes an oxygen depletion sensor that automatically shuts the heater off if oxygen levels are too low, helping prevent carbon monoxide risks. The push-button ignition is simple and does not require electricity, which is a plus during power outages. You can adjust the heat with a thermostat control offering high, medium, and low settings, allowing for some customization of warmth.

The heater is not designed for large spaces and has limited portability since it weighs nearly 16 pounds and isn’t designed for quick moving around. Because it is ventless, it’s important to ensure proper room ventilation during use. This model is a reliable, easy-to-use small propane heater with solid safety features for indoor use, especially for those who want a heater that works without electricity.

The CAMPLUX Portable Propane Heater is a solid choice for people needing a reliable heat source for camping, patios, garages, or well-ventilated indoor spaces. It delivers 12,000 BTUs, which is good for warming small to medium-sized areas, offering about 6 hours of heat on a standard 1 lb propane cylinder. Its lightweight design (just 9.4 pounds) and built-in handle make it easy to carry around, and the added LED light is a handy feature for use in dark conditions. Safety is well considered here, with automatic shutoff features for low oxygen (ODS) and tip-over protection, which adds peace of mind when using it in less controlled environments. The ignition system is simple and efficient, using a piezo igniter that doesn't require batteries or matches, so you can get warm quickly without fuss.

One drawback is that the heater doesn’t come with the propane tank or hose, which means you’ll need to buy those separately. Also, while the radiant burner is effective, it’s best suited for outdoor or very well-ventilated areas due to propane fumes. This heater is not for large indoor rooms but works well in tents, garages, or small patios. In summary, it is a user-friendly, portable heater with decent power and safety features, ideal for casual outdoor use and small indoor spaces where ventilation is good.

The ProCom ML300TBA-B is a ventless propane heater delivering a strong 28,000 BTU output, capable of warming spaces up to 1,400 square feet. This makes it suitable for medium-sized rooms like bedrooms, living rooms, or offices. It features adjustable thermostat controls with three heat settings, allowing customization of warmth to your comfort. Its slim, modern design fits well in most rooms and can be mounted on a wall or placed on the floor using the included hardware, providing flexible placement options.

A key benefit is safety: the heater includes an oxygen depletion sensor (ODS) that shuts it off if it detects low oxygen levels, helping to prevent carbon monoxide buildup. It uses a push-button ignition that is simple and does not require electricity, making it useful during power outages. This also means it operates independently from a power source, although at nearly 30 pounds, it is not extremely lightweight.

Since it is designed primarily for indoor use, proper ventilation and installation are important to maintain safety. Although compact, it is not easy to move frequently due to its weight and mounting options. The heater lacks a battery or electric ignition option, which some users might prefer for added convenience. The ProCom ML300TBA-B is well suited for those seeking a reliable propane heater with solid heating power and safety features for residential or office spaces, balancing heating efficiency and safety effectively.
