Its a good way to study using the renewable energy of the sun to provide helpful effects, in this example hot water. You may use these instructions to build solar power water heaters that will basically heat enough water to use in the home, and save you thousands over time in energy bills. By using the sun rather than traditional fules to heat your water you will be stopping deadly greenhouse gasses from being released into the atmosphere, helping to stop global warming.
Think hot water isn't a hot topic? The average electrical water heater serving a family of 4 uses 6,400 kilowatt-hours of electricity each year, releasing 8 tons of CO2, according to the School of Wisconsin's Solar Energy Laboratory. That's more than a standard car! Gas-fired heaters release about two tons of CO2 a year.
Solar power water heaters are very reliable and can work in any climate. There are several different types, including those with pumps and those that work passively. You will need a storage tank and some kind of solar collector. Some homeowners use the devices exclusively (sometimes with a gas or electric tankless water heater as a backup ), whilst others pair them with other systems as pre-heaters.
The idea behind solar power water heaters is relatively simple, and with the right information, you'll be on the way to making your own heater and saving huge amounts of money.
