Active solar heating: what it is, how it works and advantages

Active solar heating is a system that harnesses solar energy using technical devices, such as solar collectors, to convert it into usable heat in a building. Unlike passive solar heating, which relies on architectural design and materials that naturally harness sunlight (e.g., south-facing windows and thermal insulation), active solar heating uses technology to capture
