Designed by EcoZoom, the Plancha stove has two burners and a 20 cm (8 in) chimney for cooking with wood, charcoal, or biomass briquettes.
Designed by EcoZoom, this Plancha stove is a portable, durable stove featuring two burners with two removable tops on a cast iron griddle to enable direct access to the flame when cooking with pots. It has a refractory metal lining, ceramic insulation, hinged combustion chamber doors, and no sharp edges and it is designed to burn wood, charcoal and biomass briquettes. Video available on how to use the stove.
EcoZoom operation and production center is located in Nairobi, Kenya.
Kenya, Uganda, Somalia, Ethiopia, Nigeria and Zambia, among others.
EcoZoom has projects going in several countries around the globe. They work with partners on scales ranging from single villages to entire countries.
Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all.
Individuals and families in developing countries in need of eco-friendly and efficient cooking products.
EcoZoom has a production volume capacity of 60,000 stoves/month (considering all commercialized models) that can be scaled to fit any project. Since the date of commercialization (April 2016), EcoZoom has distributed over 105 Plancha stoves in various markets around the world. Interview with representative

Design specifications include the two independent combustion chambers, each fully insultated for heat retention and transfer, a durable cast iron top that heats up evenly and can be used both with flat and round-bottomed pots and pans, a 20 cm (8 in) long chimney with an end cap and protective fence, and a space available at the back of the stove that allows storing of wet wood or biomass for drying.
This stove weighs 36 kgs and its dimensions (LxWxH) in cm are 55 x 45 33.
Technical support provided by the manufacturer. EcoZoom also provides a list of Frequently Asked Questions.
This product has a 1-year warranty, however, the approximate lifetime is 5 years.
The manufacturer designed the stove to reduce emissions and fuel consumption.
According to the manufacturer, the EcoZoom stoves save up to 70% fuel and produce 60% less smoke than traditional open fires. The manufacturer also claims that the stoves can save a user up to 200 USD/year and save 30 trees and 12 tons of CO2 over the 5 year lifetime of the stoves.
Vetted performance is unrated in the Global Alliance of Clean Cookstove webpage.
Please note that this stove is not rated for indoor use.
EcoZoom also commercializes the Zoom Dura with the possibility to add a stove carrier bag.

Ecozoom indicates that they use the standard laboratory test conducted for cookstoves – the 5-liter Water Boiling Test (WBT). The WBT is a laboratory-based test that can be used to measure how efficiently a stove uses fuel to heat water in a cooking pot and the quantity of emissions produced while cooking. This test can be used to evaluate stove changes during development, compare the effectiveness of different designs, select the most promising products for field trials, and ensure that manufactured stoves meet intended performance.
