The Sleeptight 800 Series heaters are designed to roll right into the infested area. Their compact size readily transports through small elevators and narrow hallways. Using less than 3.5 amps, the sleeptight 800 Series plugs into a single 110/120 VAC outlet and provides up to 80,000 BTU/HR of heat capacity. The sleeptight 800 Series utilizes standard 20-LB. propane tanks, the same tanks used on home BBQ grills. This high heat capacity, equal to 23.4 kW of comparable electric heaters, allows the sleeptight 800 Series to quickly raise the temperature to treat areas up to approximately 1000 square feet.
