A three-day’s workshop on the construction of the summer variant of a solar water heater for local communities was held in the Nisur village, Bartang valley of GBAO (Gorno-Badakhshan Autonomous Region) from 8 to 10 of October 2015. The event was organized by the "Little Earth" environmental organization within the "Clean Energy" project and with the assistance of NGO "Oyandasoz" - a local partner. The workshop was attended by 10 countrymen from Nisur and neighboring villages. It is worth noting that workshop was conducted by three local craftsmen, who participated in the same course on construction of the solar collector a few years ago. Workshop was divided into three parts. At the first day new participants received theoretical knowledge and later made a wooden base for the water heater. During the second day participants were engaged in assembling and painting the plastic pipes. On the third day, they assembled all the items together and tested the device. "Little Earth" staff members monitored the process and provided necessary help to the trainers. The water heater’s testing was conducted in the afternoon on open space in the yard. The air temperature was +21 degrees Celsius. 18 liters of cold water (capacity of the device’s pipes) was heated up to an around +40 degrees in 25 minutes. After an hour the water temperature reaches +70 degrees Celsius. The water heater has sparked interest among local residents, who came to look at the completed device performance. According to the general decision made by the participants of the workshop water heater has been presented to the Guldastshoev Zoirbek - one of the craftsmen and resident of the Savnob village. Number of tools that can be further used for the manufacture of such type of solar water heaters was provided to the NGO "Oyandasoz" by "Little Earth". "The design of self-made water heater is simple and its manufacture requires only minimal technical skills. Such devices can be a good helper for people in remote mountain communities that have no access to electricity. They improving sanitation and increasing comfort, and also demonstrate the benefits of solar energy use, "- said Anton Timoshenko - staff member of "Little Earth "and one of the organizers of workshop.
