Have you ever stepped into a lukewarm shower, bracing yourself for a burst of icy water instead of a comforting heat? It might be time to say goodbye to your old water heater. It can be tricky to tell the difference between a minor glitch and a sign it's time for a replacement.

In this blog, Lubbock A-1 Plumbing, LLC's plumbing specialists help you uncover the telltale signs your water heater is on its last legs, tell you more about the life expectancy of your unit, and explain the benefits of upgrading to a modern water heating system.

Armed with this knowledge, you'll never be at risk of an icy cold shower again.

What Is the Average Lifespan of a Water Heater?

The average lifespan of a traditional water heater tank is about 8 to 12 years when you perform regular maintenance. Newer tankless water heating systems offer more longevity with an expected performance time of up to 20 years.

What Effects How Long Your Water Heater Will Function Effectively?

Several factors can impact your water heater's effectiveness and how long it will remain safe and functional. Maintenance is a critical consideration. Regular flushing and draining of your tank-style water heater can extend its lifespan by keeping particles and contaminants from attaching to elements or corroding your tank.

Water quality is another determinant of unit longevity. Hard water with a higher mineral content can cause buildup and damage heating elements. Hot water usage in individual households also influences product life expectancy. Homes with high hot water demand will naturally put more stress on water heaters, potentially shortening their lifespan.

How Do You Figure Out the Age of Your Water Heating Unit?

It's ok if you don't know precisely how many birthdays your water heating unit has had, but it's a good idea to start investigating now so that you know for sure.

The first thing you can do to locate this information is to look at your tank to find the manufacturer's label. This label is generally found on the upper part of your tank. It contains important information like your unit's model, serial number, and specifications.

After you've found the label, check it for a serial number. This number often has the manufacturing date encoded within it. The format of the serial number varies by manufacturer.

Signs Your Water Heater Could Benefit From Repair Work

While some signs suggest that you need a new water heater, there are also situations where repair work can restore your existing unit.

Here are some signals that your water heater might benefit from repairs:

  • Leaking at the pressure relief valve: This safety valve releases pressure to prevent tank ruptures. A small leak might be due to a faulty valve. Minor leaks at this site can be resolved with a valve replacement.
  • Lack of hot water but no leak: This could be due to a malfunctioning heating element or thermostat. Replacing one or both heating elements and repairing your unit's thermostat are typically the answers to this problem.
  • Lukewarm water: Sediment buildup can reduce heating efficiency. When sediment is the culprit, flushing your tank to remove it often restores hot water function.

What Causes Water Heater Tank Leaks?

General wear and tear and improper functioning are usually to blame for water heater tank leaks. As your unit ages, the tank is constantly exposed to high temperatures and pressure. Over time, this can lead to corrosion, especially when the protective glass lining within your tank deteriorates. This corrosion can weaken your tank and cause cracks or holes, resulting in leaks.

Water contains minerals and sediment that can settle at the bottom of the tank. This buildup can insulate your water heater, reducing efficiency and causing the water to reach higher temperatures. The extreme heat can accelerate corrosion and contribute to tank leaks.

Your tank's temperature and pressure valve is a safety feature that releases excess pressure if it builds up too much inside the tank. A faulty valve that leaks constantly or fails to activate when needed can put stress on your tank and potentially lead to leaks.

Leaks can also develop around the connections where pipes enter and exit the water heater tank. These connections can loosen due to vibrations or thermal expansion and contraction.

Why Is Your Water Heater Hissing?

A hissing water heater can produce a sound like escaping steam or a high-pitched sizzle. It might come in short bursts or be a constant hiss. The source behind this hiss can vary. Sometimes, it's your tank's safety valve releasing pressure, which is a normal occurrence in small bursts.

Persistent hissing could indicate trapped steam from mineral buildup at the bottom of your tank or even hot water coming into contact with cooler condensation on its exterior. If the hiss is accompanied by leaks or unusual water temperature, it's time to investigate the issue further to prevent a host of avoidable problems.

When Should You Schedule a Water Heater Replacement?

When your system starts to fail, showers that used to be steamy might turn tepid quickly, leaving you shivering mid-wash. You might also notice the hot water running out faster than usual, forcing you to wait longer between showers or baths for your tank to refill.

Strange noises, like banging or knocking, can erupt from your water heater as well. These signs, coupled with rusty or discolored hot water, all point toward an aging water heater nearing the end of its service.

A water heater that's nearing the end of its manufacturer's recommended lifespan may put you at risk of:

  • Cold showers: As your water heater ages, it becomes less efficient at heating water. You'll likely experience lukewarm showers that quickly turn cold, or you might run out of hot water.
  • Increased utility bills: A failing water heater has to work harder to maintain the desired temperature, leading to higher energy consumption and increased costs on your utility bills.
  • Leaks and water damage: Over time, corrosion can cause leaks in the tank. A small leak can go unnoticed for a while, causing water damage to your flooring, walls, and surrounding areas. A major leak can lead to a flood, causing significant property damage.

When you encounter any of the above, it's a good idea to schedule an inspection and consider a replacement to ensure a steady stream of hot water for your home.

Capture All the Benefits of Upgrading Your Residential Water Heater

Upgrading your residential water heater will bring a wave of positive changes to your home. Modern water heaters boast significantly higher efficiency ratings than older models, leading to substantial savings on your utility bills. This eco-friendly upgrade also translates to a lighter environmental footprint.

New water heaters often provide a more consistent and reliable hot water supply, eliminating cold showers and ensuring everyone in your household has a comfortable bathing experience. Advancements in technology have led to quieter operations, and the inclusion of safety features like leak detection systems, automatic shutoffs (to prevent overheating), and temperature and pressure relief valve design improvements offer better reliability and performance.
