Utilizing the Sun in Solar Water Heating

Solar hot water heating units are becoming moderner as energy costs have upraised over the past 10 years. Technology for solar water heaters has too turned more modernized and effective, as the fact that the price of the devices has lessened, thus growing more of a manageable choice for an enlarged base of people. These solar water heating units use the sun’s ability to heat up the water before it comes into the home. They are often applied in combination with a conventional hot-water heater so that the water is pre-heated before it gets into the traditional heater, so economizing on energy cost, but even so supplying nice hot water to the household.


There are two main types of solar water heating systems: one uses a circularizing pump and controls and the other does not. Both types of solar water heating units demand high insulating material so that the benefits of the sun’s heating do not get missing out the sides of the water tank while awaiting use. There are also two types of systems that are practiced: one simply has a single tank which unites the solar water heating with the backup heater, and the another system has a solar heating storage tank that pre-heats the water before it passes away into the traditional water heater.


There are several unique types of solar accumulating materials that are in use in solar water heating. One is a flat plate collector which is a glazed, water resistant box that holds in an absorber plat that is under whatsoever glass or plastic covers. Other type is the ICS or Integral Collector Storage system which as well applies a glazed box, but this type of system incorporates black tubes or tanks in the box rather than an absorber plate. This permits the water to go through the solar collecting system so that it can be heated on its way to the backup water heater.

In active solar water heating, the water is moved all over the household by the system. In the direct circulation system, the water runs through the solar collectors into the house over the use of pumps. In a passive system, the water runs over the system because of the natural heating of the water, since the colder water sinks to the bottom and the warmer water arises to the top. There are other types of solar water heating systems in both the passive and active types that are practiced commercially and for special situations such as the heating up of pools.
