Heating water is one of the most common uses of solar energy. Solar energy can heat water as high as 140ºF or some can even heat it higher. There are two methods in which solar energy can be used for heating water. They are either direct or indirect systems. The direct system, as the name suggest is where the water is directly heated by solar energy. The sun’s rays are directly passed on into the pipe filled with water. The pipe is linked to an insulated tank which normally stores the water. But in this direct system of heating, you are required to maintain the entire solar water panel properly and keep it free from dirt and minerals. These systems also work best in the places which have a warmer climate and natural conditions are very hot. Again solar pool and hot tub heating systems also work in the direct system of solar water heater. However the water collector is sometimes removed as it might get too heated up.
The other available system is the indirect way of heating where as the name suggests water is not directly heated up. Rather there is some kind of a fluid with a low freezing point which is passed on to absorb the sun’s energy. Here the pipes are evacuated of air and the entire pipe is kept free. The thin copper layer laminate of the pipe then turns up the heat as the fluid passes through it on the back of each pipe. As the temperature in the pipe increases the pump circulates heat which reaches the water tank and thus produces hot water out of it. Here again the performance and usage of a hot solar water panel depends on the location and climatic condition of the area. Again here it is better you call for a skilled and professional expert who would give you the best suggestion and would also install it properly. Nowadays not only families and household people are opting for solar water heater but also business man and corporate. Also it is very cost effective and saves more than 50 percent of your bills had you used an electric heater. Electric water heaters are the ones which consume maximum energy. Hospitals and swimming clubs are very fast switching to this mode of heating since it doubles their earning and reduces there expenses.
In a solar water heater the most important part I that the tanks have to be insulated well and properly. Through water it is known that electricity travels faster. One should be very careful while using the solar water heater panel. Also one should have a back up pan in place. There are chances of a solar water heater getting damaged or it might need to be cleaned regularly. The fluid that passes though might many a times bring in chemicals or dirt. But is for sure that the entire world especially countries having longer winters are looking for solar water heater as the best option available.
