Like most other things, a hot water tank does not have an exact life expectancy which will allow you to prepare for its replacement. Because appliances such as hot water tanks are essential to everyday life and can be quite costly and time consuming to repair, many people often ask “How can I determine a hot water tank lifespan?”  Although there is no clear and direct answer to this question, there are some warning signs that you can look for which will help you to determine if your hot water heater is on its last leg so that you can prepare for the inevitable. However, this is just an estimate and will not be able to provide you an actual timeline on when you can expect your hot water tank to go out. 

When a hot water heater goes out it can often take days for you and a plumber to come up with a compatible time which is convenient for both of you. For this reason, when your hot water heater breaks, it could mean the absence of hot water in your home for days which makes everyday living extremely hard. Having to wash dishes and laundry in cold water and take cold showers can be a huge inconvenience; therefore, you should be aware of the warning signs so that you can be as prepared as possible.

How can I determine a hot water tank lifespan?

One of the first signs that your hot water heater tank may be going out is the presence of rusty water. This is due to the breaking down of the metals within the hot water tank which creates rust within your homes water supply. When water heater tanks are extremely old and the metal begins to severely break down it can even tint the color of the water indicating a problem. Another common warning sign is that the hot water will not come out as hot. If water begins to come out cooler than normal this could indicate that your hot water tank lifespan is near its end.  

If you are finding puddles near your hot water tank, this could also mean that your hot water tank is on its last leg or needs to be repaired. If puddles are found in or near the area of your hot water heater this could indicate a slow drip. Lastly, you should consider the age of the water heater tank as well. Most water heaters typically last on average between 8 and 10 years. Although this does not mean that it will always go out at this point, it may be wise to start saving some money for replacement when the time comes so that you are prepared for this unwanted, yet necessary expense.
