Background
Forests are reduced to 3 % of Tajikistan‘s
surface;
Wood continues to be the most important
fuel in rural areas;
Deforestation leads to mudslides and floods;
Cow dung cakes that would be needed as
fertilizer are also widely used as fuel;
Reduced agricultural yields are the
consequence.

Development of Prototype Conducted survey and stove users demands
identification
15 models were tested in the field according to
criteria such as
Energy-efficiency,
Multi-functionality,
User friendliness,
Enhancement of living comfort,
Affordability.
On the basis of the findings, a prototype
was developed. 4

Characteristics of Prototype
Prototype has a truncated form of cuboid.
The stove has 2 burners with a diameter of 17 cm and 26 cm,
The mesh around the stove
To heat water a metallic pipe that is 15 mm in diameter is
connected to the stove has a double spiral shape
The burning chamber’s door has draft regulation; the smaller
door at the bottom serves to remove the ash.

Accessories, cont. Increase of multifunctionality:
Heat exchanger allows baking;
It allows heating of 2 rooms to comfortable
temperature;
Water boiler provides hot water;
Water radiators function like a central heating for
the house.
An additional 30 % of energy can be saved
through the combination of the stove with
the accessories.

Production
Modern machinery increases efficiency of
work and allows mass production;
A blacksmith workshop currently produces
the stove and the accessories;
A stove manual explains the stove
production step by step thus enabling
other blacksmiths to take up the
production.

Marketing of the modified stove
Stove will be sold to market conditions;
Price is competitive as it could be kept
below the price of the traditional stove;
The marketing will be done via retailers,
markets or directly by blacksmith
workshop.

Promotion of the modified stove
A promotion campaign will introduce the
stove in the market;
Environmental aspects will be part of the
promotion;
100 selected multiplicators receive a stove
for free;
The first 100 buyers receive the
accessories for free as incentive.

Perspectives
A new project plans to
Make available a variety of EE and RE
options for dwellings;
Identify the best option(s) according to the
building, priorities and financial capacities of
the owner;
Substitute part of the fuel by biofuel where
the plants have grown on degraded
lands thus rehabilitating them;

Perspectives, cont
Capacitating the manufacturers and
providers of the required goods and
services;
Great emphasis will be put on the
monitoring of the environmental impact
of the measures;
A cooperation with the CDE,
university Bern, allows to do this
according to scientific standards. 17
