Solar heating is a method of using sunlight to generate heat for various applications, such as warming water or indoor spaces. This technology typically involves solar collectors, which capture sunlight and convert it into thermal energy. The heated water or air can then be used for residential heating, swimming pools, or even industrial processes. There are two main types of solar heating systems: active and passive. Active systems use pumps and controls to circulate heat, while passive systems rely on building design to maximize sunlight exposure. Both methods contribute to energy efficiency and can reduce reliance on fossil fuels, benefiting the environment and reducing energy costs.
