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.

With a BTU rating of 11,000, it provides adequate heating for areas up to 1,600 square feet, ensuring a consistent and comfortable temperature thanks to its advanced modulating technology. This feature effectively reduces cold spots, which is a great benefit for maintaining an even warmth throughout the room.

Safety is a notable strength of this heater. The cool-to-the-touch cabinet and self-diagnostic electronics help ensure safe operation, making it suitable for homes with children. Moreover, the programmable thermostat allows users to customize their heating preferences easily, and it connects with Wi-Fi-enabled systems for modern convenience. This can be particularly appealing for tech-savvy users looking to integrate heating control into their smart home systems.

On the energy efficiency front, the heater stands out by minimizing fuel consumption while delivering adequate warmth, which can lead to savings on energy bills. This aspect makes it a wise long-term investment for those looking to optimize heating without sacrificing comfort. However, there are a few drawbacks to consider. The Rinnai EX11DTP is designed specifically for indoor use, which limits its versatility for outdoor applications. Additionally, while its compact design is space-saving, some users may find its beige color and wall-mounted form factor less visually appealing, depending on their interior decor. Potential buyers should also be aware that the installation process may require professional assistance or careful DIY skills, especially given its venting requirements. The Rinnai EX11DTP is a reliable and efficient indoor propane heater, well-suited for urban residents or anyone looking to maximize their home's heating efficiency.

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.
