The Procom ML300TBA-B is a ventless liquid propane space heater rated at 28,000 BTU, enough to heat up to about 1,000 square feet. It uses blue flame technology that warms the air and circulates it like a central heating system, with a thermostat to hold your set comfort level. It needs no electricity and no chimney or duct, so it works during power outages and installs with the included wall bracket or base feet. It suits garages, workshops, cabins and rooms a central system doesn't reach; against electric space heaters it delivers far more heat output, but it burns propane and adds indoor moisture and combustion byproducts, so ventilation matters.

It has a steel finish and a space-saving design. It can stand on its own, and a wall mounting bracket is included.
