As the rule of thumb, our water heaters may not last that much as you may think. They are designed to last about 10-15 years or less. However, to answer this question of "how long does a water heater last?" actually, it depends. To maintain the water heater is not a joke. You need to know how to flush your equipment step and step and perform it well. With this, you are guaranteed to maintain the unit as per the manufacturer's recommendations. In fact, you will get several more years. If you fail, the tank will also fail eventually.
There are water heaters that can last substantially longer, those with the fiberglass tank. They also come with a lifetime warranty for your benefit. Damaged tanks can't be repaired, regardless of the type of materials used to make them. It might be tempting to purchase a low-model price brand, keep in mind that it may not last long. It may also have a short lifetime warranty. It's advisable to spend a more up-front for the model with 10 to 15-year warranty.
How long do water heaters last?
In every household, warm running water availability is essential in today's living. From frequent hand-washing, baths, cooking to showers, dishwashing, and laundry. Think how much miserable you would be with lack of hot shower in the morning! Your water heater is of great help since it is a staple in every home.
As time goes, you are bound to see signs of replacing your heater. You may be surprised when to replace your water heater, mainly because you do not have a clue how long is its lifespan. Your water heater’s life length will depend on what sort of water heater you have. Not only how well you take care of it.
A high-quality hot water tank, adequately installed can last for eight to twelve years. Consistent use and time are what wears down the container. A tankless water heater can have a lifespan of twenty years. This is because it is not always in use as the hot water tank. Here are the signs on when to replace your water heater.
Why Tank Fail
Your water heater tank may fail due to these two causes:
This is the first cause which can emerge as a big problem for you. This where psi of water contained in the tank exceeds specifications. Overpressurization happens due to two causes. It be can be due to too much pressure exerted at the inlet or excessive heating. However, you can avoid these situations by keeping the hot water lower for heating issues or at 140F. You also need to install an adjustable valve directly at the inlet.
At your home, you need a water heater expansion tank if there is a closed water supply system. Remember that when water in your water heater tank heats up it causes thermal expansion or it expands. Here, this water needs enough space to go. In the open water system, the pressure pushes back to your home water supply. When it comes to a closed system, the additional pressure is relieved by flowing it into expansion tank temporarily. If this pressure finds nowhere to go, then your tank might literally burst.
This is another reason that makes your tank to fail. The sediments buildup in your tank turns to be dangerous as you’re the tank becomes older day by day. Contaminants and chemicals in the water usually cause corrosion. It can also cause rust inside the tank. Eventually, the water heater tank ends up leaking.
Once a slight leak occurs, the pressure inside the water heater tank forces water through a flaw, this increases the amount of leakage. Nevertheless, even a cheaper water heater can last longer, all is needed is proper care. Once the anode rod is caked with contaminants, the rod is eaten away leading to the replacement of the equipment. This component is inexpensive than purchasing a new water heater.
Electric and Gas lasting
The electric water heater lasts 2-3 years longer as compared to gas models. However, this is not always. Most people tend to prefer gas heaters. This is because they are more environmentally friendly and economical than electric. It is also easier to replace your old unit because it is cheaper and easier for this gas model.
Whenever you are choosing a water heater, select the one with a longer lifetime warranty. Moreover, choose the one that is easier to replace when the leakage occurs. Environmental friendly and economical are other features to look at to ensure your heater last longer.
Signs on when to replace your water heater.
Age is a more significant factor in determining whether to replace a water heater. Keep a record on when you bought the water heater. Most of the heaters can last between eight and ten years. Of which ten years is the age recommended for a replacement of a water heater. Whether or not your water heater will always show symptoms. Before a decade passes, you should do a replacement.
Water around your heater.
When a leak gets noticed in anything that is always a bad sign. Like a tank full of hot water leaking? That’s definitely not good. Expansions of the metal in the tank always results to water leaks. These leaks occur because the tank is ever exposed to thousands of heating cycles causing the expansion. A leak in your hot water tank does not only cause damage to your house, but it can end up being costly regarding your utility bill. It’s worth checking your tank regularly.
Odd noises from your water heater
Do you hear weird sounds, banging, clunking from your hot water tank? This sign always occurs nearly the end of your heater’s lifespan. In homes where large amounts of warm water are consumed, the problem of rumbling noises will emanate louder as the tank heats the water. Causes of such noises are due to sediment buildup. Sediments can wear out your water heater rapidly resulting in inefficiencies.
A decrease in water temperature levels.
Hot and warm water are among the essential requirements in a home. Without warm water you cannot take showers or do the necessary requirements. If there is a drop in water temperatures after heating, which means the water heater needs to get replaced. The sudden loss of heat in your water is likely to be caused by a broken heat element, a small size of your water tank compared to your house and a misadjusted thermostat. This problem is expected to mean that you need a new water heater. Not like the other problems where it’s easy to rectify.
