How to Know When It’s Time to Replace the Water Heater
A home’s water heater is, in some ways, the heart of the plumbing system. Without it, everything from bathing to washing dishes would be more difficult and decidedly less pleasant. So when the water heater suddenly and unexpectedly kicks the bucket, waiting for a water heater replacement can be a frustrating and uncomfortable ordeal – especially if it takes more than a day or two to get the new unit installed.
That’s why it’s so much better to be proactive about replacing a water heater that’s on its way out – before it stops working in the middle of a cold winter night. So, this article will share a few easy ways to tell if the water heater is about to fail and needs water heater replacement.
Signs of Corrosion
One of the most common reasons to replace a water heater is corrosion. This usually occurs due to a chemical reaction caused by certain minerals and other substances in the water interacting with the metal tank shell. It is a sign to replace the water heater because corrosion and rust will weaken the metal and lead to leaking.
Signs of water heater corrosion include if the hot water has a metallic smell or other unusual odor, if the hot water is rust-colored or cloudy, rust can be seen on the water heater itself, or if the water heater tank is leaking water. The best way to prevent tank corrosion is with routine water heater maintenance, where sediment can be removed, and the anode rod can be checked and replaced to protect against corrosion.
Little to No Hot Water Coming From Fixtures
Perhaps the most obvious sign that the water heater needs replacing is a lack of hot water or when it runs out too quickly. The hot water could run out faster than usual, only get lukewarm, or come out cold. Warm or lukewarm water typically indicates a failing burner or heating element, but if the water is coming out cold even when the hot water tap is turned up, it may mean that the water heater has stopped working entirely.
Of course, losing hot water may not always mean the water heater is beyond saving. In some cases, water heater repair or maintenance might do the trick, particularly if the issue is just a single faulty component like a thermocouple or a sediment buildup in the tank. In some cases, the water heater storage tank may simply be too small to meet the household’s hot water demands, so it may be a good idea to upgrade to a larger unit or a tankless water heater. So, if homeowners notice water temperature issues, they should call a professional to diagnose the problem.
The Water Heater Is Getting Old or Needs Frequent Repairs
Another signal that it is time for water heater replacement is the age of the water heater. The average life expectancy for a conventional storage water heater is about 10-15 years, while a tankless water heater's lifespan can be over 20 years. So if a storage tank water heater is over 10 years old or a tankless water heater is nearing 20 years old, it’s time to consider replacement before getting stuck without hot water. Older units also tend to be significantly less energy efficient than newer models, so it benefits homeowners not to wait too long before replacing their old water heater.
On the other hand, if the water heater in a home requires frequent repairs or isn’t as reliable as it used to be, it’s probably not worth keeping around. Before long, the repair costs will come close to or even exceed the cost of a new water heater, and it’ll have to be replaced eventually in addition to all those repair costs, making it more cost-effective to replace the water heater. So, if homeowners have an aging water heater or one that constantly needs repairing, they should consult a plumber about replacing it.
