Solar water heat exchangers function by providing safe, efficient transfer of heat between a heat transfer fluid and potable water in a domestic water supply. Used in closed loop solar thermal systems, thermal heat exchangers are part of a freeze-protection system, which expands the possibilities for where solar water heaters can be installed.
SolarTown's selection of thermal heat exchangers includes products from high-quality manufacturers. Heat exchangers can be installed inside solar hot water storage tanks, but are also available as external units. External heat exchangers can provide additional hot water without the cost of adding another storage tank to your solar water heating system.
