Frequently Asked Questions about Solar Water Heaters

What is the difference between a passive and active solar water heater?

Passive and active solar water heaters are two types of systems used to harness the energy from the sun to heat water. The main difference lies in how they operate and the level of control they offer.

Passive solar water heaters rely on natural convection and gravity to circulate water through the system. They do not require any external power source or mechanical devices to operate. These systems typically consist of a solar collector, storage tank, and sometimes an insulated backup heater for cloudy days. The collector is usually positioned horizontally or at a slight angle to maximize exposure to sunlight. As sunlight heats the water in the collector, it naturally rises and flows into the storage tank, while cooler water from the tank replaces it in the collector. The water temperature in a passive system is influenced by the weather conditions and the sun’s intensity.

On the other hand, active solar water heaters use mechanical equipment, such as pumps and controls, to circulate water through the system. They are more sophisticated and provide greater control over the water temperature. Active systems consist of solar collectors, a storage tank, a controller, and a pump. The controller monitors the temperature in the collectors and the tank and activates the pump when the temperature difference reaches a certain threshold. This process ensures efficient transfer of heat from the collectors to the storage tank. Active solar water heaters can have direct or indirect circulation systems, depending on whether the water flowing through the collectors circulates directly or through a heat exchanger.

In summary, a passive solar water heater operates without the need for mechanical components or external power, relying on natural convection to circulate water. An active solar water heater, on the other hand, uses pumps and controls to circulate water and provides more control over the water temperature. The choice between the two depends on factors such as climate, available space, and desired level of control and efficiency.
