How much space can a Buck Stove infrared wall heater effectively heat?

Hello, thank you for reaching out. Buck infrared heaters are available in multiple BTU sizes (10k, 15k, 18k, 25k, 30k BTUs), allowing customers to choose a heater based on the heating requirements of their space. Proper sizing for a unit is important for comfort and performance, and the manufacturer recommends sizing the heater approximately for the application while providing adequate combustion and circulation air. These heaters are designed as supplemental room heat, rather than being used as the primary heating source for an entire home. If you have additional questions, please feel free to reach out over the phone to our Customer Service line at 1-888-901-5460. Have a great rest of your day.
