Solar expansion tank is a vital item while operating a solar energy system. This is because of the heat, which the system is likely to incur during the conversion of direct sunlight to energy. As we all know the mere presence of heat can result to expansion of anything. The expansion it will cause on the system leads to the additional pressure, which is likely to strain the system if no tank is available.
Why You Need Solar Expansion Tank?
The tanks will act as a stabilizing agent for the pressure during the heating process. They do this through absorbing thermal expansion which in most cases is experienced. The tank will provide an extra room for the emitted pressures while at the same time aid in the heating process. The tank is normally made of a chamber; inside the chamber is a bladder that is filled with air.
The bladder is in most cases locked inside the chamber. During the stabilization period, the expanding fluid emitted during the heating process is absorbed safely to the tank. This achieved through compression of air that is already present in the bladder. However, it is important to note that, the size of the tank will contribute hugely to the volume of the fluid emitted during the heating process. It also depends with the size of the pipe system that is used by the pipes, in the solar heating system.
It is also on point to say that solar expansion tank can withstand even the highest temperature of about 210 degree. This means that, this equipment can be used even during summer period. The device comes with a unique heat resistant diaphragm to stall all the temperatures. During the period when electricity is out, the system comes in handy to provide the energy needed in the house. The diaphragm of solar tanks ensure that the solar system pressure do not go beyond of drop way below the needed within the system design.

The diaphragm inside solar expansion tank ensures that space within the tank that is occupied by pre-charged gas and that of solar fluids is maintained. In case of any expansion of fluid due to the heating activity, the diaphragm expands to the gas chamber. This results into the increment of space for the increased fluid volume. The same process happens again in case the volume of the fluid decreases during cooling process. The diaphragm will squeeze into the needed size to create a balance that is required.
Factors to Consider Before Purchasing Solar Expansion Tank
First and foremost, it is always important to consider the need of purchasing solar equipment system. For example, a person may need to purchase the solar system for heating the swimming pool. This will help in coming out with the best tank to buy, that which will also come in handy in terms of serving the purpose it is intended to do. The same tank a person will purchase to serve in heating the swimming pool will be totally different from that needed in maybe storing the energy needed as a form of electric power.
A person intending to purchase a solar expansion tank must also consider the cost. This is the amount of money he or she will need before buying the system. This will help him decide whether to go for the solar system that comes with the available tanks, or purchase them differently. All these will depend with the size of his pocket and his tastes and preferences. However, before a person opt for the tank to buy, it is very vital to have a good background research on the company selling them. Make sure that the tank that is on sale is the one needed. This is in terms of quality and the performance.
