Solar Water Heaters









Solar water heaters can be a very useful way to saving money on your power bill. A water heater alone can easily cost a family of two $20-$40 dollars per month. Now think if you have a larger family what that could cost you throughout the year.

Heating your water by the sun is not a new concept. Back in the 1970’s there was a big push to conserve energy by heating your water with the sun. It however did not last very long. There are a few different types of solar water heaters out there. They can be as simple as laying a garden hose in the sun to a full enclosed system that uses a heat exchanger to transfer the heat from a liquid that does not freeze to the water.

The system that you decide on depends upon your location. If you live in a warm climate where it never or very rarely has freezing temperatures then you can go wth one of the more simple systems where the sun directly heats the water. The basics of the system include the solar water panel, some pipe and an old water heater. This is my favorite system because you can utilize your old water heater as a backup in case it is cloudy and there is not sufficient sun to heat the water. The old water heater also acts as a storage tank for the hot water and keeps it hot and ready for whenever you need it.

If you live in a climate that sees freezing and below freezing temperatures, you will need to go with a system that uses an antifreeze type of liquid just like your car so the water in the system does not freeze. You would also be wise to utilize your old water heater as a backup for when there are clouds or if the panels are covered in snow. You can also use the old water heater as a hot water storage tank using this method as well.








One of the best thing about solar water heaters is that they do not need electricity to run! This not only will save you money on your power bill but it will also allow you to take hot showers when there is no power! Imagine that there is a storm that comes through while you are at work and the power is out. You will still be able to take a hot shower.

Another advantage to having a solar water heater is that once you have it installed you are one step closer to being off the grid. In my opinion, this should be one of your first things to consider before going off the grid. Before you go and install $30,000 worth of electric solar panels on your house, put a solar water heater up there and start saving right away. It is also more efficient to heat your water with the sun than it is to power your old electric water heater by the electric solar panels you are thinking about putting up. This is because there are always losses with electricity. There will be losses due to heat, wire and electronics. This means that you are better off to heat your water with the sun first. This also means that you can save some money on the electric solar panels because the load that they will need to carry will not be as great. Electric water heaters can typically pull anywhere between 1500 and 4500 watts. This is 1500 to 4500 watts that you will not need to buy solar panels for.
