How Solar Water Heaters Work?

Solar water heater can be a cost effective solution to generate hot water at home, while making use of a natural free resource, the sun. The solar water heating systems basically include storage tanks and solar collectors. How these two combination work together to heat up and generate hot water at home?

Getting the Lowdown on a Water Heat Exchanger

Why do people need a water heat exchanger? This device is built for efficient heat transfer using one medium to another. A solid wall can separate this medium so that they never mix, or it can be through direct contact.

This is used for solar water heating systems. Exchangers are used to transfer solar energy absorbed in solar collectors to the liquid or air used to heat water or a space.   

This material can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron.
