Solar heating system distributes heat in many ways like with hot water radiators, through forced air and through radiant floor. Active solar heating is based on the type of fluid which is used for heating. There are two types of fluids which are used for the solar heating system. The liquid and the air placed in a collector. Collector is a special apparatus designed for the solar heating. The working of these collectors is really simple. The collectors are functioned for using water and anti freeze mixtures.
Depending on your domestic heating needs you should be able to install a proper collector. One should also take into account the climate. An average solar heater will produce up to 70% of the total heat needed for your household daily operation. And it’s quite costly if the system covers less than 50 % or more then 70% of your house heating demands. That is why solar collectors are usually supported by some sort of back-up systems that bring additional heat. The heat transfer fluid present in these collectors absorbs the solar heat and quickly transfers it. The liquid based collectors are considered more efficient as compared to the air based systems. The reason is air is considered a less efficient medium for transferring heat as compared to liquid systems. However, the ability of the air based systems cannot be neglected. Solar air heating systems generate heat heating liquid often heat water. While the collectors which are used for heating air use an air based heating collector.
How solar heating works
These solar systems absorb a lot of heat from sun during the day time. When the system is enough heated, it transmits the heat to the internal heating space. Then this heat is further distributed to the entire living space. Active solar systems also use electric or motorized equipments such as drivers, pumps and fans. Liquid based active solar systems are faster than the liquid heating systems. Moreover the ability of the air heating systems retains the heat for long. Also air heating systems are safer because a mild leakage does not create more panic. Air or liquid solar collectors are often positioned in walls or ceilings to hide their emergence. Air heating is more appropriate for individual rooms. If one requires an efficient central heating system than one must prefer liquid air heating system. Liquid solar systems store heat in water tanks mostly. Liquid solar systems mostly require flat plate collectors. Here, it should be noted that both kind of heating systems require backup system to function well.
Solar heating systems are an excellent and economical way to centrally heat the entire home. Active solar heating systems are considered cost effective worldwide for their well-organized working and quick results. They are much cheaper than the electric, oil and propane heating systems. The price and cost of installation varies with the variety of heating systems. Some systems are of commercial use and they are less expensive than the small systems. If we express the cost in terms of dollars than commercial heating systems cost approximately from 60 to 80 dollars at large. Since these solar heating systems benefit society because of its ecological means of heating some governments offer tax cuts or will reward credits for using solar systems. Finally, the prices for thermal solar collectors is different, depending on their power and length. Usually, such collectors don’t need any special service and their warranties last for 10 years or more. You should take this into account so that you can see that modern solar systems are a money saving and pollution free solution. It lowers your fuel bills and most importantly does not harm the environment.
