This item is priced to make heating affordable and Portable with a digital controller this 2000kW heater is a great addition to any campervan, van, tent, roof top tent, ice fishing tent, or even a shed. Our Portable heater comes with a 2.5 gallon tank which provides almost 30 hours of heat. Simply fill up the tank at any gas station and then use the 12v Female Cigarette Adapter to hook your heater up to a power source. With our digital controller you can also set a temperature and the heater will heat the space to a specific temperature so you don’t get too hot. Simply run the heater hose to the place you want to heat and then bring the the controller into the heated space. No need to do a permanent install like a Webasto or Espar so during warmer months you can just leave your heater at home. Our heater compared to the planar unit runs off gasoline so the exhaust is much cleaner and won’t stink out fellow campers. We also used a digital controller unlike the Planar portable heater.
