Differences Between Active and Passive Solar Heaters

1. Definition and Functionality

Active solar heaters use mechanical or electrical devices to collect and distribute solar energy. They involve pumps, fans, or other components to circulate heat or hot water throughout a building. Passive solar heaters rely on natural heat transfer mechanisms, such as conduction, convection, and radiation, to distribute solar energy without the need for mechanical or electrical assistance.

2. Energy Efficiency

Active solar heaters are generally more energy-efficient than passive solar heaters. They use pumps or fans to control the distribution of solar energy, resulting in more consistent and efficient heating. Passive solar heaters, while still effective, may be less efficient because they rely on natural heat transfer processes.

3. Installation and Maintenance

Active solar heaters often require professional installation due to the complexity of the system and the involvement of mechanical or electrical components. Regular maintenance is also necessary to ensure proper functioning. In contrast, passive solar heaters are typically simpler to install and maintain since they do not involve additional equipment or moving parts.
