Solar Evacuated Tubes Used In Water Heating Systems If you are looking forward to save substantial money on monthly electric bills, you need to seriously reconsider the usage of traditional water heating methods. For lowering carbon footprint too, this traditional system that is in use for a long time needs to be replaced by an advanced and highly efficient method of heating water. These days, one of the systems that are gaining a lot of popularity in water heating is the powered Solar Evacuated Tubes. This is surely a great option for which cost is a huge factor. In case a new home is being built or planning to refinance one, this Solar Water Heating Systems can be installed without much hassle, though specific federal deductions in tax comes into the picture. On the basis of energy being consumed, one will find a lot of saving being possible in monthly energy bills. Letâ€™s have a closer look to the different categories of the modern solar water heaters, and the major advantages which you can get by installing them to your home.
Two categories of solar water heaters Solar water heating systems are available in two major categories. 1. Active solar heating system Relying upon traditional source of external power like electricity, this system comes with circulation pumps and is controlled by this external source. 2. Passive solar heating system
For operating fans, pumps, etc., 100 percent solar power is used in this system.
The main Solar Water Heating Systems accessories include: · Charge controller – This ensures the longevity of the battery, prevents overcharging, recharges it, and thwarts wasteful draining. · Inverter – This gadget converts the DC being generated by the solar panels to AC that most households use. · Solar back-up kit – This is a handy gear for those who plan to use a combination of the traditional electricity and that which is generated through solar panels.
There are many types in active systems which is further categorized intoDirect Circulation System- This is a great choice in all those regions where the climate never moves towards freezing point. It offers great water heating option. Water temperature at the storage tank bottom is compared with water at the top of the storage tank in this system. In case there is considerable difference between two temperatures, a small pump is activated through an electronic control that helps in circulation of water across solar collector. It heats it and later returns to the top tank. It offers both advantages as well as disadvantages. # Pros: In warmer climates, this system proves to be highly efficient system in heating water. # Cons: In regions where freezing is a common occurrence, this system is not quite effective. Indirect Circulation System- This system is also referred to as drain back system. An anti-freeze or heat transfer fluid is used in this system. This fluid is pumped using a heat exchanger. From solar collector, the transfer of heat reaches the water thereby heating it. # Pros: This system is perfect for climates that are cold. # Cons: In comparison to direct circulation system, this is comparatively less efficient. Just like Active systems, Passive systems are further divided into various types of heating systems: Integral Collector System- For water circulation, this system do not utilizes automatic Solar Evacuated Tubes for control or pumps. Moreover, storage of water and collection of energy units are joined to form one component meaning no insulation. This is done so as to ensure solar heating reaching water.
