päikeseküttevõrk
Päikeseküttevõrk refers to a solar thermal system designed to heat water. These systems typically consist of solar collectors, a storage tank, and a heat transfer fluid. The solar collectors, usually mounted on a roof, absorb sunlight and convert it into heat. This heat is then transferred to a fluid, often a mixture of water and antifreeze, which circulates through the collectors and a heat exchanger in the storage tank. The heat exchanger transfers the heat from the fluid to the water in the tank, thus heating it. The heated water is then available for domestic use, such as showering, washing dishes, or heating purposes.
The efficiency of a päikeseküttevõrk depends on several factors, including the intensity and duration of sunlight,
