UMDHT-68 MkII 30KW Portable Industrial Diesel Space Heater

Diesel air heaters give steady, dry heat off a 12V battery, so they work where there's no mains power. Shop Giantz, Thermomate and more.

Types of diesel heater

  • 12V diesel air heaters: 2 to 5kW heaters with an LCD remote, made to install in caravans, motorhomes, campervans and 4WDs.
  • Portable all-in-one heaters: 5 to 8kW units with the fuel tank built in, some with Bluetooth app control, for sheds, workshops and camp sites.
  • Industrial space heaters: 30 to 50kW portable diesel heaters for building sites, warehouses and large sheds.

Choosing a diesel heater

Match the power to the space: 5kW for a caravan or small shed, 8kW for a larger van or workshop, and an industrial heater for big open areas. Check whether you need 12V, 24V or 240V power, and always run the exhaust outside.

Frequently asked questions

A 5kW 12V diesel air heater suits caravans, motorhomes, campervans and small sheds. An 8kW heater suits larger vans, workshops and garages. 30 to 50kW industrial space heaters are for building sites, warehouses and big open sheds.

Yes, when it's set up as the manual says. 12V diesel air heaters burn fuel in a sealed chamber and send the exhaust outside through a pipe, so only warm air comes into the room. Keep the exhaust pipe outdoors and away from openings, give industrial heaters plenty of ventilation, and fit a carbon monoxide alarm in any sleeping space.
