Mr. Heater 35,000 BTU HERO Cordless Forced Air Propane Heater

Used for Football Sideline warming stations. Much easy to work with/transport than large kerosene heaters. The self contained battery is also great as we don't need to bring generators. Used about a half tank of a full 20lb propane tank for the game.

I've had this for about 5 years I believe. When it works it works well and puts out good heat. Major design flaw is that when it's unplugged and not running the electronics still draw on the battery, so unless you have a convenient place for storage that you can keep it plugged in all the time plan on replacing the battery every year. the electronics will draw the battery down permanently destroying it, won't take a charge and even if plugged in if the battery is no good the unit won't run. No battery=no run even if plugged in.
