If you have ever felt hot water trickle out of a garden hose that’s been sitting in the sun, you’ve experienced solar hot water in action. Essentially, a solar hot water system is made up of a solar thermal collector, a well-insulated storage container, and a system for transferring the heat from the collector to the container vis-à-vis a fluid medium, which in some circumstances is the water to be used itself.
Being as there are, on a global scale, near countless applications using domestic, commercial and industrial hot water, there are also nearly as many opportunities to apply solar thermal technologies to heat this water. But today the market is changing, and both the economic and environmental costs associated with using gas and electricity to heat water are being challenged by more efficient, less costly systems.
