Solar water heating systems have a good economic payoff, and are manageable systems to build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can easily make this solar hot water yourself to supplement your existing system and save on energy costs. The system will pay for itself in several years.
There are only a few items that you will need and the pay-off of having hot water that continues on and on is worth the effort.
