A water heater is defined as a heater and storage tank that supplies heated water. Depending on the usage a standard water heater can last upto eight to twelve years. The tanks which are available in the market these days are mostly steel lined with either porcelain or glass. These materials can deteriorate due to oxidization over time.
Due to regular wear and tear of the inner section of these tanks, you will notice water leaking out from them. At these times you may require a repairman to help you repair the tank. In some places in US, where the weather may get dangerously cold, the requirement of a water heater is felt immensely.
If proper care is taken of these tanks then the lifespan of these utility devices can be increased by upto two or three years. There are some useful ways to help extend the life of these heaters:
* Setting up an expansion tank: When water is heated between 50 degrees to 120 degrees, it tends to increase on an average by 2%. Since the tank is a closed unit and due to the presence of a valve (which prevents the backflow of water to the main supply) the pressure created by increased water may damage the tank as well as the plumbing system. Setting up an expansion tank can actually help, since the heated water can get transferred to these expansion tanks.
* Cleaning and flushing your tank: Regular flushing and cleaning your water tank, especially if it is very old will help a lot. Regular accumulations of water can build up sediments which can harm the inner section of the tank.
* Installing a 2nd anode rod: If you get a serviceman to install a 2nd anode rod in your water tank, the lifespan of these tanks can be increased considerably. An anode rod is made up of aluminum or magnesium that goes through galvanic corrosion over time. The corrosion of these rods actually delays the process of the tank getting damaged. It has been noticed that numerous homeowners in US, have installed a 2nd anode rod in their water heaters.
