2kW Diesel Heaters
2kW diesel heaters are the right size for an insulated panel van, small boat cabin, tent or small camper. A smaller heater runs at mid-power more of the time, which keeps it cleaner and quieter than a big heater turned right down.
They use roughly 0.1 to 0.25 litres of diesel an hour and only 1 to 2 amps once running. Not sure if 2kW is enough? Use the size calculator.
