What are Solar Water Heaters?

Solar water heaterTechnological advances allow homeowners to get creative with every aspect of their home, including the water heater.

Standard water heaters are still useful and have become more energy efficient over time. But if you're looking for an entirely new experience, consider installing a solar water heater.

What Is It?

According to the U.S. Department of Energy, solar water heaters keep water hot by generating heat from the sun. The best part: Solar heaters can be used in any climate, including Hickory, North Carolina, even when there is no sunshine.

How It Works

Every solar water heater consists of solar collectors and storage tanks. Passive heaters don't come with circulating controls or pumps, while active ones do. Active heaters fit any climate, but keep in mind there are two subsets of this heater, direct circulation and indirect circulation.

Indirect circulation is when a non-freezing heat transfer fluid is pumped through a heat exchanger and then into your house. Direct circulation heaters pump water through a collector and then into a home.

There are also two types of passive heating systems. Thermosiphon systems are more complicated because water will flow through the system while warm water rises and colder liquids sink. This means the collector needs to be under the storage tank to ensure warm water rises.

The second type of passive system is an integral collector-storage. This type has the tank and collector joined together. As a homeowner, this means you don't have to worry about controls or circulation pumps. With this system, tap water is stored and heated in the joint collector and tank.

Due to the number of solar water heating options, you might find yourself overwhelmed trying to decide on one. Not only that, but you may need the help of professional installers.
