Perfect for those looking for a to go green at their home or business, solar hot water heaters are an eco-friendly and affordable way to maintain a reliable hot water supply without the need for traditional forms of power.
How Do Solar Water Heaters Work?

Traditional hot water heaters burn natural gas/propane or use electricity from the main power grid to heat water for the home. Solar hot water heaters collect their energy from the sun, and use that energy to heat water for use in the home or commercial building. On a basic level, they include a collector, which absorbs energy/heat from the sun, storage tanks for the heated water, and pipes that connect the two together and tie it into the home. There are a few main types of solar hot water heating systems:
Active and Passive Solar Water Heating Systems
Active solar hot water systems use pumps and controls to circulate liquids within the system. Cold water (or transfer fluid) is pumped into the collector, where it is warmed and then pumped into the storage tank. Because they use pumps, the tanks in active systems can be located below the collector. Passive hot water heating systems do not use pumps to distribute water, instead relying on gravity and water’s natural tendency to circulate when it’s heated. These systems are usually less expensive and longer lasting, but also less efficient. They also require that the storage tank be located above the collector to allow for the hot water to rise.
Direct and Indirect Systems
Solar hot water systems are also divided into direct and indirect circulation. The former of the two is best suited for warmer climates that rarely experience freezes because it involves sending the potable water directly through the collector (located outside) to be heated. Indirect systems use a freeze-proof transfer fluid to collect heat and transfer it to the water. They are slightly more costly, but have the added benefits of protection from freezing and overheating.
Choosing Your Solar Water Heater System

Each home or business has different hot water needs, which also means they need slightly different systems. From picking the size of the tank to choosing between a passive or active system, direct or indirect circulation, and more, the ways to customize a system are seemingly endless. However, that doesn’t mean it has to be confusing, and the experts at Renewable Energy Corporation can help you quickly and easily determine the best setup for your needs. We understand solar water heating systems inside and out, and how they fit into different homes and businesses.
