The average lifespan of a hot water heater is between ten and fifteen years. There are numerous factors that could affect this lifespan, such as the quality of water that goes into the heater and regular water heater maintenance. Even a well maintained hot water heater does have to be replaced at some time. If you want to lengthen the lifespan of your hot water heater, then it is important that you take care of these appliances and keep it in good working condition. If the boiler which contains the heater has problems, then the whole hot water heater may also have to be serviced.
Water heaters contain a combination of elements like fuel, heating elements and a burner. There is a heat exchanger in the middle, which converts the natural gas or oil into liquid form. When the liquid enters the burner, it heats up the gases which are present inside the liquid thus giving it steam or hot water. This process takes place very fast and the liquid may be cooled too quickly by the burners thus causing it to become hot again. This causes the burner to cool down and the entire unit may have to be shut down and started up again.
Hot water enters the tank of the heater through a small tube that is connected to the main supply pipe. If there are any clogs in the tank, then this may prevent the hot water from passing through the tube and into the house. If the capacity of the tank is less than what it should be, the water may leak and enter in the house through the drain which may be a considerable distance away.
It is advisable to regularly maintain the capacity of the tanks of water heaters so that the capacity of water is maintained properly and there are no problems. Water which is of low quality may have bacteria in it and these may cause diseases. The pipes and tanks will get clogged if the fluid is of low quality. This will result in a reduced capacity of the tank as well as may make the water heater replacement necessary. Regular servicing of the tank and pipes will ensure that the water is of good quality and there are no problems related to the fluid.
There is a special type of tank called a booster. This is placed over the heating system and helps in increasing the circulation of hot water within the tank. Once the hot fluid has been exhausted from the tank through the booster, the system will then lower the temperature of the remaining fluid. This process ensures that there is enough hot water in the house when the heater returns. It also helps in keeping the house free of water marks that are left on hot water when it comes out through the hot water booster.
Water heater replacement can be prevented by using the latest models of water heaters that have an automatic shut off feature. These heaters will shut down automatically when they are filled with water. The shut off will ensure that there is a constant supply of hot water in the house. People should also try and use more water than they think they need as excess amounts may cause damage to the tank.
