Sun in winter / Not frozen water pipes

Sun in winter
Sun in winter

In the countryside, water pipes are usually out of doors. It’s too cold in winter to have liquid water, so this causes the problem that people in the countryside have difficulty in using water in winter. The product we designed takes advantages of solar energy and transforms to the heat to keep water liquid and ensure the water is warm for people to use.
