Solar Water Heater Cost

The cost of solar water heater it is almost to the cost of an electric water heater. Price range is about $700- $2000, depending on size and manufacturer.
Solar water heaters work through the use of a storage tank and a solar collector. There are two different types of solar water heater options, which are active and passive, where active water heaters have circulating pumps and passive heaters do not. Well insulated storage tanks are required for most water heaters running on solar energy. For residential applications, there are three different types of solar collectors that are used with these water heaters flat-plate collectors, integral collector systems and evacuated tube solar collectors.

There are two different types of active water heaters that you can choose, direct circulation systems and indirect circulation systems. With a direct system, pumps circulate the household water into the home through the collectors. With an indirect system, pumps circulate a unique heat-transfer fluid through first a heat exchanger and then the collectors.

Passive solar heating systems tend to be less expensive than their active cousins, but they do not tend to be as efficient. They can be more reliable, however, and may even last a lot longer. There are two different types of passive solar heating systems to choose from: integral collector systems and Thermosiphon systems.
