When it comes to hot water, nobody wants to be reminded of its unpleasant side effects. If your neighbors are currently enjoying the benefits of unlimited hot water, thank your water heater. It’s what keeps your home warm in the winter and cool in the summer, and it’s also responsible for keeping your bathing and laundry routines on schedule. However, if your water heater is in need of some TLC or has seen better days, its ability to provide hot water may be interrupted. If your current water heater isn’t up to snuff, there are a few things you can do to make sure things don’t get too messy (or even dangerous) for your home’s inhabitants. Keep reading for helpful insight on water heater repairs, replacements, and maintenance—and what you can do now to avoid unpleasant surprises in the future.

Check your water heater’s operating temperature.

The thermostat on your water heater should be set between 120° F and 140° F to produce safe, effective water at the temperatures your family needs. If your water heater’s thermostat is set lower than this, it will take longer to heat up enough water for your family, and it may not always reach the desired temperature. If the thermostat is set too high, your water heater will run out of hot water more quickly, and you may have to resort to using cold water during peak times (like when you’re doing laundry).

Check your water heater’s anode rod.

In addition to being responsible for heating up your water, water heaters also help remove harmful substances from your water supply, like magnesium and calcium. These substances can cause water to taste bad, smell bad, or even stain laundry and fixtures. To counteract these substances, water heaters employ an anode rod. An anode rod is a cylinder of lead or another metal that is installed inside the water heater and exposed to your water supply. The rod slowly corrodes, but it prevents harmful substances from entering the water heater and affecting your family’s water supply.

Get your water tested.

If your water heater is older than 10 years, you should have it tested by a professional to make sure it is working properly and can continue to provide you with hot water. Doing so will help you identify potential problems with your water heater before they cause too much damage. Depending on your location, you may be able to find a water testing company that offers home water testing, or you may want to hire a professional. Additionally, many insurance providers will cover the cost of water testing.

Change your water filter regularly.

If you have a water filter installed in your home’s water supply, make sure you change it regularly to ensure it isn’t allowing contaminants to enter your water supply. If you have a well or a city water supply, you can find out how often you need to change your filter by visiting your local water utility’s website. If you have a filter installed in your home’s water supply, but you aren’t sure how often you need to change it, trust your instincts: if you start to notice a change in the taste or smell of your water, it may be time for a change.

Install a new water softener if your water tastes like salt.

If your water tastes like salt, it may be caused by the presence of minerals in your water supply. If this is the case, you may want to install a water softener to counteract the minerals in your water supply. A water softener works by attracting minerals in your water supply and removing them, which helps to reduce the amount of minerals in your water and improve its taste and quality.

Check the connections and hoses of your water heater.

If your water heater is leaking or otherwise not producing the results you’d like, you may want to inspect its connections and hoses to identify potential problems. If it’s leaking, you may be able to repair it by replacing the connection or hose. If you find that it’s leaking due to an issue with a particular material (like copper), you may want to replace it with a more durable alternative.

Conclusion

Whether you’re hoping to get more out of your water heater, or you’re simply ready for an upgrade, it’s important to know what needs to be addressed and what your options are. With the right information, you can make the best decision for your home’s plumbing and your family’s long-term needs. Be sure to keep an eye out for signs of wear and tear on your water heater, and don’t be afraid to get it checked out if you notice anything out of the ordinary. With a little TLC, your water heater can last for years to come.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.
  • Your older water heater is getting up there in age
  • It's making strange noises
  • You're getting rusty water out of the tap
  • Your hot water doesn't last as long as it used to
  • There are water puddles around the unit
120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
Sediment buildup shortens the life of your water heater and adds to your energy bill by reducing its efficiency. Draining two or three gallons of water is usually enough to flush out sediments, but always let the water flow until you no longer see particles in the bucket. Regular water heater maintenance will always extend its lifespan.
  • You're overusing hot water.
  • The water heater tank size is too small for your household.
  • Your hot water heater is tankless.
  • Sediment or minerals have built up in your water heating system.
Soft water can actually corrode the water heater anode faster. When the anode wears down, the corrosive elements will move on to the tank. So if left alone, a water softener system can actually shorten the lifespan of a water heater.
