Jolentho Stove from Indonesia

Jolentho in javanese (a local language in Indonesia) means rounded and bulky, so Jolentho Stove means bulky and rounded stove. We gave it the name because the stove liner is made of round and bulky potteries. Every part of the liner is made from pottery, including the grate.

The liner is divided into 8 parts to simplify production and tranportation. To make a liner, one needs to have pottery making skill. For simplicity, the liner is produced by a professional pottery maker. The users only need to buy, install and cast a sand-cement mixture surround the liner. Although cement are not ressistant to heat (easily crumbles), pottery liner provide protection so that cement can last longer. Properly made, the stove will last for 10 years.

The stove has 3 potholes and a chimney to suit the needs of palm sugar producers in Indonesia. The technology is simple: fuelwood burns above grate. Grate provide air suppy and dispose ash. The enclosed combustion chamber provides improved combustion quality. After heating the pot in hole #1 rom beneath, hot smoke is channeled to pothole #2 and #3. There are baffles in pothole #2 and #3 to maximize heat transfer. Finally, the smoke exits through chimney. Chimney also provide draft that boosts combustion.
The innovations we offer are cost and time efficiency and simplicity in stove making, and. It only takes 1 men, 2 hours and 19.25 USD to make a Jolentho Stove and the stove is ready to use within 3 days. This is much more simpler, compared to a mud stove, which requires 4 men, 16 USD and 3 days only to make mud stove and additionally 17 days to get mud stove ready to cook.
