20 Liter InStove: For large homes or small institutions

20 Liter Stove20 Liter Stove with patent-pending downfeed fuel chute can operate unattended for up to one hour when pre-loaded.

Since InStove's inception, our focus has been institutional stoves of large capacity. The 20 Liter InStove offers a compromise between household and institutional stove.

Based on InStove’s best-in-class 60 and 100 Liter institutional rocket stoves, the 20 Liter InStove's balance of portability and capacity makes it ideal for small institutions and communities, mobile kitchens and emergency situations, or as a companion to one of our larger models.

The 20 Liter InStove includes a patent-pending self-feed firebox, which can hold enough fuel (soon to include pellets via pellet-feeder) to burn for up to an hour with no tending or refueling. Stainless steel construction provides an extended lifespan and protection from the elements, and each stove comes with a removable chimney, ash tray, folding fuel chute, and stainless steel or aluminum pot and lid.

At about two feet wide and a foot and a half tall, and weighing in at 45 pounds, the stove is small and light enough to be shipped as checked baggage. It is also designed to work with the All-American brand pressure cooker/canners and medical sterilizers with 15 to 30 quart capacities. Some key attributes include:

  • Boils 10L water in 25 min; runs pressure cooker cycle in 20 minutes
  • Over 40% thermally efficient (used with pots provided)
  • Self-feeding design allows unit to run unattended for up to an hour
  • Removable tray can be used to start fire, and remove ashes after burning
