For almost two years our hot-water-system has been in use at Lophelling-Boarding-School (LBS) at an altitude of nearly 3500m in the valley of Manang (Nepal). Prior to this there was only freezing cold water available in the washing room. Thanks to the solar-system every pupil is able to use hot water for washing and can enjoy a warm shower once a week. Clothes can be cleaned with warm water, too. Additionally, Palden, the cook, uses the hot water in the kitchen. By doing so he saves up to 50 USD per month on firewood. This is an asset to the environment and the school’s financial budget. On the positive side, Palden and the other staff members are able to take care of the installation and carry out minor repair measures themselves. In the valley of Manang more and more news are spread that such solar-systems provide a genuine alternative to burning wood and gas.
