Solar Hot Water Heater

In the 1890s solar water heaters were being used all over the United States. They proved to be a big improvement over wood and coal-burning stoves. Artificial gas made from coal was available too to heat water, but it cost 10 times the price we pay for natural gas today. And electricity was even more expensive if you even had any in your town!

Today, solar water heaters are making a comeback. There are more than half a million of them in California alone! They heat water for use inside homes and businesses. They also heat swimming pools like in the picture.

Building a solar hot water heater is easy. If you are someone that has never built an alternative energy source, it is recommended to get one of the online do-it-yourself guides to help you along the way. Developing your own solar or wind power system can reduce your electric bill as much as 80% and can be built for around $200
