What is a Solar Double Wall Heat Exchanger?

A solar thermal system warms water by using a heat exchanger. This heat exchanger is powered by the energy collected from solar panels. A double wall heat exchanger is similar to a single wall heat exchanger, however, it has a double barrier that protects the portable water from the solar fluid. The double layer works as extra protection for your hot water reserves. 

Common Material For Double Wall Heat Exchangers:

  • Copper

  • Steel

What Do I Need a Double Wall Heat Exchanger For?

Double wall heat exchangers are necessary whenever toxic fluids are used as a heat transfer fluid. Incorporating the double wall heat exchanger can eliminate the chance for cross-contamination. Make sure to check your building code to see if this type of heat exchanger is required for your project.
