Indirect Diesel Heaters

We have a range of indirect space heaters available. These units provide large volumes of dry, clean, fume-free warm air. Indirect diesel heaters are for enclosed areas with less ventilation. You can use them to heat marquees, workshops, church halls, barns, and more, where unclean air is unsafe.

Indirect Diesel Heaters

Portable space heaters for enclosed spaces

Indirect diesel space heaters are safe and versatile solutions for temporary and emergency climate control. You can place them outside the area you want to heat and duct the warm air inside through flexible hoses. Any fumes are expelled outside through an exhaust safely. A set-up like this is ideal for heating enclosed areas when you need floor space, like marquees, event tents, garages, church halls, factories, and warehouses. The air throw is enough to circulate the warmth right around the room, creating a comfortable environment.

You can also use indirect models to heat spaces from inside, as they have a flue outlet. You place them in a suitable area, with access to plenty of air, and build a flue pipe chimney that leads out of a wall or roof. The heated air circulates directly while the fumes are exhausted out into the open. Using an indirect heater this way is suitable for barns, stables, farm buildings, where the unit might be unattended, and it is safer to have it indoors.
