Active solar heating is a technology that captures sunlight and converts it into heat for various applications, such as heating water or indoor spaces. This system typically uses solar collectors, which are devices that absorb sunlight and transfer the heat to a fluid, usually water or air. The heated fluid is then circulated through pipes to deliver warmth where needed. These systems can be installed on rooftops or in open areas to maximize sunlight exposure. Active solar heating is often used in residential and commercial buildings, contributing to energy efficiency and reducing reliance on fossil fuels. It is an important component of sustainable energy solutions.
