If you have an electric hot water system in your home, then you know that it represents one of the more expensive items on your household budget. Consequently, you will want to ensure that it is as efficient as possible as it provides much-needed hot water for your family on any given day. Yet these systems are not designed to last forever and will eventually need to be replaced, so how can you tell when the time has come?
As a rough rule of thumb, a new hot water tank system should last you between eight and 12 years. Much will depend on how often you use it and the quality of the water that flows through the pipes, of course, but don't be surprised if things start to go wrong towards the tail end of that age range.
Some homes have to deal with a water supply that contains a particularly high level of minerals. Over time, these will build up within the tank and may compromise its ability to perform. When these levels get too high, you may start to notice some strange noises from within the tank. The sedimentation may move around when the water is very hot, and this will cause vibration.
Eventually, parts of the tank will begin to corrode, although this can be kept at bay through the use of a sacrificial anode. Nevertheless, when the tank starts to rust from the inside out, you may notice drips on the floor nearby.
When a hot water tank gets older, it will become far less efficient. You may have to turn the thermostat up gradually as the months go by and may still be unhappy with the water received.
Don't forget that technology is moving forward in leaps and bounds and you'll find that a modern-day tank is far more advanced than your aged installation. This is another reason for you to think about a new product, as these modern features may help you to cut down on the cost of your electricity in the future.
Making Your Decision
Have a look at your tank and see if you can find the installation plate. This should give you an indication of the age and will help you to draw your own conclusions. If you've noticed some leakage, strange rumbling sounds and lower efficiency, it's probably time for you to get a brand-new hot water heater installed as soon as possible.
