The MH18B Big Buddy Portable Propane Heater from Mr. Heater is designed to heat enclosed spaces of up to 400 square feet, such as cabins or tents. There is a high-medium-low switch for outputs of 4,000, 9,000, or 18,000 BTU per hour, and the heater can connect to either two 1 lb, or one 20 lb separately sold fuel cylinders. An integrated fan increases the heating capacity of this unit, blending radiant and convection style heat. The heater contains an electric ignition which can be lit by pushing and rotating the knob, and two swivel regulators for adapting usage from the cylinders to a remote gas supply. The MH18B also features an oxygen depletion sensor and accidental tip-over safety shut-off for safe use.
