12 V heaters and air conditioners for caravans, campers and 4WDs, plus 12 V fans. Our diesel heater kits run off your 12 V battery and a small fuel tank, so you can heat the van without mains power or gas. For cooling, choose myCOOLMAN reverse cycle roof top air conditioners, a portable camping air conditioner, or a 12 V fan.
