The wall-mounted design helps save space, and the powered exhaust allows for both vertical and horizontal venting, providing flexibility during installation.

Safety features include a self-diagnostic control module that enhances reliability, though installation requires a minimum clearance of 8 feet from the floor to the base of the unit. While the heater is designed for indoor use, it’s important to have proper ventilation to ensure safety and efficiency.

On the downside, the unit does not come with a thermostat, hose, or regulator, which are necessary for operation and could increase the initial investment if you don't already have these components. Additionally, while it boasts a noiseless operation, the powered exhaust might still produce some level of sound that could be noticeable in quieter environments. If you're considering using LP gas, you’ll need to install the conversion kit, which adds to the complexity of the installation. While it performs well in providing heat, the lack of included parts and potential installation challenges may require some DIY skills or professional help.

However, there are some important considerations to keep in mind. First, while it includes a natural gas to propane conversion kit, the thermostat, hose, and regulator are not included in the purchase, which means additional costs may arise for complete installation. Also, the unit requires a ceiling mount, which might not be ideal for everyone and could involve a more complex setup.

However, there are a few downsides to consider. The reliance on electric power may limit its use in remote areas where electricity is not readily available.
