Detailed Product Description

The solar water heater relies on the natural circulation of water between the collector and the tank or heat exchanger. In this type of installation, the tank must be located above the collector. As water in the vacuum tubes is heated it becomes lighter and naturally rises into the tank. Meanwhile, cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation through out the system. These systems move household water or a heat-transfer fluid through the system without pumps. This kind of passive systems have the advantage that electricity outage and electric pump breakdown are not issues. This makes passive systems generally more reliable, easier to maintain, and often inexpensive.
