What Is A Solar Water Heater?

A solar water heater is a cost-effective type of water heater that converts sunlight into heat. They can be used for residential or commercial buildings and can be used in any type of climate with a reasonable amount of sunlight. These systems also can operate independently or in conjunction with electric or gas heaters.

How Do They Work?

When it comes to solar water heating, there are two types of systems that can be implemented – a direct system or an indirect system. The key differences between these systems is that a direct system circulates and heats potable water directly, whereas an indirect system circulates heat-transfer fluid and uses a heat exchanger to transfer heat from the fluid to the water.
