SOLAR HOT WATER HEATERS: THE DESIGNS

The designs and the type of components of the solar water heaters vary a lot. But we may consider five main designs, with different costs and complexities.
Solar Water Heating Designs
Main solar water heating designs:

- the batch ICS solar systems (an ultra-simple system for moderate climates);
- the thermosyphon solar systems (for moderate and other climates);
- the solar open-active heating systems (for moderate and hot climates);
- the drainback systems (cold climates);
- the anti-freezing pressurized systems (cold climates).
