Rent a 170k BTU forced air heater that uses both propane for a heat source and electricity for the operation of the fan and the ignition.
The L.B. White Tradesman 170 propane space heater has a heat output of between 125,000 to 170,000 BTU using a 625 CFM fan and is the second largest heater that we rent. It requires a 120V power supply and a 25 gallon propane tank to operate. The maximum operating time with a full tank is 12.5 hours. With your rental, we provide a full propane tank and then top it off on return, so that you only pay for the propane used! This large propane heater is for use in workshops, garages, construction sites and farms with proper ventilation.
*** Not for use in residential living areas or inadequately ventilated areas! Proper ventilation is required during operation! At least a 3 foot by 6 foot opening to fresh air! ***
