Types of water heaters
The purpose of water heater is to provide hot water within the premises of the building. These heaters are constructed in such a manner that the cold water is entered into the heater from one side and the burner placed at the bottom of the heater evaporates, boils the cold water and then this hot water flows out when we open our tap. These heaters are generally of two types. The most commonly used type is the storage tank water heaters. These are the heaters in which the water remained stored within the heater so that, the hot water remains available whenever used.
The cold water that we enter into it goes down and when get heated from the gas burner it stores in a tank. In order to improve the quality of these heaters now a day a large number of insulated sheets are used so that a better insulation provides greater heat retention and less loss of heat. With the improvement in the insulation system there a better heat exchanger to transfer more heat from the energy source. There is certain water there is factory-installed heat traps and these taps allow water to flow into the tank but prevent unwanted flow of hot water out of the tank. For the improvement in heat exchange system the gas burners are replaced with electronic burners which reduce heat loss through flow- vent.
There are tankless water heaters and these heaters provide hot water only in the hour of need. They have a system that they heat only the required water and when the tap is closed they also do not produce heat. In this way no much heat loss is made and therefore there is no need of installing heavy insulators in it. These heaters are usually installed near areas where water is required at one site for example in our baths and kitchen. In these heaters certain other things are installed to increase the efficiency of these heaters.
There are solar energy heaters and the basic purpose of these heaters is that they trap the solar energy and heat the water is the heated water is then supplied to the household for consumption. The use of these heaters is not appropriate for the areas that are cold as they will not provide enough energy to these heaters to work. The water heaters are real important for us to fulfill our domestic needs. In severe cold the heaters provide us cold water at relatively low cost as compared to the geysers.
These heaters have a very limited capacity of working therefore they cannot be used for industrial purposes where the large boilers are required. There are different types of applications of these heaters. . These heaters are very quick at their service and the users of these heaters are contented with its efficiency, its durability, its cost and its monthly expenses. We see that there many other applications of these heaters as the small sized heaters are used in beauty saloons for heating water that they utilize for giving their clients steam during facial.
