- Is it safe to use indoors?
- Only in ventilated spaces such as a garage with the door cracked or a construction site. It burns propane and produces exhaust, so never use it in a sealed bedroom or small closed room.
- What size propane tank does it need?
- A standard 20 lb grill tank works, connected with the included 10 ft hose and regulator. A full tank runs several hours on high.
- Does it need electricity?
- Yes. The blower fan runs on 110 V, so you need an outlet or generator. The burner itself is propane.
- How much area will it heat?
- Mr. Heater rates it for about 950 square feet. In a well-insulated garage it keeps the space workable; in a drafty space expect less.
- Is $115 a good price?
- Walmart lists it at $115 as of November 7, 2026, and it is the only new price shown, so there is no recent range to judge against. Compare with other 30,000 to 40,000 BTU forced-air heaters before buying.
