10 Best Propane Wall Heaters 2026 in the United States

The Rinnai EX38CTWP is a direct vent propane wall heater with a heating power of 36,500 BTU, suitable for medium-sized indoor spaces like bedrooms, home offices, or small commercial areas. It features an electronic spark ignition and a seven-stage modulating gas valve, which help maintain consistent and efficient warmth. The built-in electronic thermostat allows temperature settings between 60°F and 80°F, covering common indoor comfort levels.

Safety is well-addressed with child lock functionality, self-diagnosing electronics that monitor the heater’s operation, and automatic shutdown if ignition or combustion fails. Its direct vent design brings fresh air from outside and vents exhaust outdoors, making it safer and cleaner for your living space compared to unvented heaters. The unit measures about 37 inches wide and 26 inches tall, requiring sufficient wall space for installation.

This model has been discontinued, so buyers should consider the newer EX38DTWP model for current support and parts. Assembly is not required, and the heater is approved for use in modular and mobile homes, adding to its versatility. With strong safety features and reliable propane heating combined with decent temperature control, this heater is a solid choice for users needing a dependable wall-mounted propane heater for homes or small commercial spaces.

The Empire Visual Flame 65K BTU Room Heater is designed for those seeking efficient heating solutions for indoor spaces. With a robust 65,000 BTU output, it can effectively warm larger areas, making it suitable for homes that require significant heating capacity. Its flame propane heat type provides a visually appealing fire effect, adding a cozy ambiance to the room. The inclusion of a blower helps to distribute heat evenly, enhancing comfort in the space.

One of the standout features is the remote control, which offers convenience, allowing users to adjust settings without needing to get up. This can be particularly beneficial in colder months when you want to stay cozy. Additionally, its size (29-9/16 in. height, 20 in. depth, and 34 in. width) means it can fit well into various room designs, and its beige color complements many interior styles.

However, there are some drawbacks to consider. The heater is quite heavy at 142 pounds, which may pose challenges during installation or relocation. It also requires proper ventilation as it operates on propane, which could necessitate additional considerations for safety and placement within your home.

The Rinnai EX08DTP is a solid choice if you’re looking for an indoor propane wall heater that offers consistent and energy-efficient warmth. With an 8,000 BTU rating, it’s well suited for heating smaller spaces up to around 1,600 square feet, such as bedrooms, home offices, or studies. Its direct vent design means it safely exhausts combustion gases outside, which is important for indoor air quality and safety. The heater comes with an electronic spark ignition for reliable, push-button starting without the need for batteries. You can control the temperature easily with its electronic thermostat, adjustable between 60 and 80°F, and it modulates heat output in 7 stages to maintain comfortable temperatures without wasting fuel.

Safety is a strong point here: the cabinet stays cool to the touch, there's a child lock to prevent accidental changes, and built-in diagnostics monitor the system constantly, shutting down or restarting automatically if something goes wrong. On the downside, the unit requires professional installation to ensure the venting and gas connections are done correctly, which adds to the initial setup cost and effort. Also, at about 53 pounds and with dimensions of roughly 27 inches tall by 18 inches wide, it’s a noticeable fixture on your wall, so you’ll want to consider your space and décor.

This Rinnai heater is well suited for those needing a safe, quiet, and efficient propane wall furnace for moderate indoor heating, particularly when precise temperature control and peace of mind with its safety features are priorities.
