Water heaters help up unwind after a long and stressful day. However water heaters have their own set of problems. One of the main causes of heater problems is the build up of sediments. What goes on inside of a water heater? Besides the water getting heated up, calcium in the water settles down to the bottom. Sand and other sediments also tend to build up in the tank. Build up of sediments happen over a period of time. If you receive a supply of hard water, then this process can speed up.
Faulty dip tube
Another issue with heaters, either electric or propane, is them not heating the water to the desired level or constantly providing warm water. This could be due to a faulty or a broken dip tube, or a damaged heating element. A dip tube is a tube that allows cold water to run into the bottom of the tank.
A broken dip tube results in cold and hot water mingling, and giving out lukewarm water. This problem can be solved by replacing the dip tube. However if there is damage to the thermostat or if a heating element has been burnt, then the cost of repairs will definitely increase.
Sedimentary build up
Heaters which work on propane gas indicate that there is something wrong with them by emitting sounds when the temperature rises. This is due to the build up of sediments and other minerals. As the temperature of the water increases, stem bubbles form due to the accumulated sediments, and escape through the top of the tank. This issue can be completely resolved by flushing out the heater.
Faulty pressure valve
Another issue that tends to plague heaters is that of a build up of pressure. Water, like other elements expands on heating. Hence water heaters have a valve which allows the pressure to be released. If the valve is blocked, the pressure in the heater builds up until the heater bursts.
