Yes, it can run on a standard 20 lb propane tank, but we don’t recommend it. Smaller tanks are more prone to freezing, especially when paired with higher-BTU heaters. As a general estimate, a 20 lb tank provides roughly 24 hours of continuous burn time, though actual runtime will vary based on heat settings and conditions.

Can this run off a common 20lb propane tank? If so, approximately how many hours will it run on a full tank? Since this is highly variable, guesses are welcome. I intend to mainly run the unit over night in a small cabin, and not 24/7.

ProductExpert30· 3 months ago
While this heater can run off a 20lb tank, this heater is designed for permanent wall mounting. It would run approximately 10-12 hours continuously. It is highly recommended to have a licensed technician install it to meet local, state, and national fuel gas codes.
