Heat Exchangers for Solar Water Heating Systems
Solar water heating systems use heat exchangers to transfer solar energy absorbed in solar collectors to the liquid or air used to heat water or a space.
Heat exchangers can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion.
This heat exchanger uses a heat-transfer fluid that circulates through the solar collector, absorbs heat, and then flows through a heat exchanger to transfer its heat to water in a storage tank. Heat-transfer fluids, such as antifreeze, protect the solar collector from freezing in cold weather. Liquid-to-liquid heat exchangers have either one or two barriers (single wall or double wall) between the heat-transfer fluid and the domestic water supply.

A single-wall heat exchanger is a pipe or tube surrounded by a fluid. Either the fluid passing through the tubing or the fluid surrounding the tubing can be the heat-transfer fluid, while the other fluid is the potable water.

DW Double Wall Heat Exchangers
Double Wall Brazed Plate Heat Exchangers - With visual leak detection
The design of the double wall brazed plate heat exchanger prevents cross contamination of fluid streams if there is an internal leak within the unit.
Two stainless steel plate walls separate the fluid streams, with an air gap in between. In the event of a leak, the affected fluid flows into the air gap and escapes out of the heat exchanger unit, enabling visual detection of the leak.
Special corrugation plate patterns within the heat exchanger promote highly turbulent flow. Turbulence dramatically improves heat transfer rates and reduces the amount of deposits inside the unit
