How Do Solar Water Heaters Work?

Solar energy is a rapidly expanding field that offers the potential to use a renewable and clean source of power to run every appliance inside a home. But if you feel a bit intimidated at the prospect of an immense overhaul of your house and power system to accommodate solar power, you can always start smaller and build from there. A good place to start: installing a solar water heater.

As we’ll explain, solar water heaters are simple devices that do not require large-scale installation jobs or immense upfront costs. If you schedule an appointment with HB Energy Solutions, we can show you how easy it is to fit homes in New Hampshire with solar water heaters… and we think you’ll find the prospect of using the free energy of the sun so enticing that you’ll want to expand solar power to more of your daily life.

Solar water heaters: the basics

As with most solar-powered systems, solar water heaters use a solar collector mounted on the roof that picks up the radiant energy of the sun. With active solar water heat systems, a pump moves water or a heat transfer fluid through the collector where it gains the sun’s heat.

Active solar water heaters come in two types: direct circulation systems and indirect circulation systems. In general, we recommend the indirect systems for installation in New Hampshire because direct circulation systems can have difficulty in sub-zero temperatures.

With indirect circulation systems, the water does not circulate though the collector itself to receive heat energy. Instead, a pump sends a heat-transfer fluid through the collectors to gain energy. This fluid is designed not to freeze in low temperatures. The heated fluid then runs through a heat exchanger within a water tank, and this heats up the water stored there.

A ­passive solar water heater does not use a pump, but instead relies on the natural rise of water as it heats and the sinking of colder water. These systems are less expensive, but tend to be less efficient as well.

Rely on professional installers to determine which of the various systems listed above will provide you with the best supply of hot water at maximum efficiency.

Solar powered water heaters in New Hampshire make a fantastic gateway to the use of the power of the sun to run a home.
