Solarwärmesystems

Solar thermal systems, also known as solar water heating systems, harness the sun's energy to heat water. These systems are a renewable energy technology that can significantly reduce reliance on conventional heating methods. A typical solar thermal system comprises several key components: solar collectors, a storage tank, and a circulation system. Solar collectors are usually mounted on a roof or in an open area where they can receive direct sunlight. These collectors contain a fluid, often a mixture of water and antifreeze, that absorbs solar radiation and heats up. This heated fluid is then pumped through a network of pipes to a storage tank. The storage tank, typically insulated to retain heat, stores the hot water for later use. A heat exchanger within the tank transfers the heat from the collector fluid to the domestic water supply. The circulation system, which can be active or passive, moves the fluid between the collectors and the storage tank. Active systems use pumps and controllers, while passive systems rely on natural convection. Solar thermal systems can be used for domestic hot water, space heating, and even in industrial processes. Their efficiency is influenced by factors such as sunlight intensity, collector design, and system insulation. While the initial investment can be higher than conventional systems, the long-term savings on energy bills and the environmental benefits make them an attractive option for many.
