According to the U.S. Department of Energy, about 18 percent of all energy used in a house goes to heating water, making it the second largest source of energy usage.

Most people can benefit from more information on how to identify when their water heater needs repairs or is about to fail. If ignored until the water heater breaks, homes can be without hot water and, possibly with a flooded basement.

Good news!  You can avoid the disruption and damage of a failing water heater.

 

Five signs that it may be time to replace your water heater:

1. Leaks or Pools of Water Around the Water Heater Tank – Leaks are never a good sign. Water puddles can be a sign that a valve needs to be tightened or replaced. Leaks and corrosion can also mean that the water heater has reached the end of its life and may be at risk of bursting. Drips and leaks can escalate. Consult with a plumber to see if repairs are possible, or if it is time for a new water heater.

2. Lukewarm Water Even at the Hottest Temperature Setting – Have your showers recently been lukewarm despite having your shower handle at the hottest temperature setting? Is it taking longer to get hot water from the tap? A common sign of a failing water heater is a lack of sufficient hot water. Consult with a plumber to see if the water heater needs flushing or other repairs, or if a water heater replacement is in order.

3. Contaminated Water Coming Out of the Faucet – The contaminated water can come in many different forms:

    • Sandy or muddy water
    • Hot water with a metallic taste or smell
    • Water with rust particles

First, determine if the contamination is in your cold or hot water.  If only hot water is affected, the problem may lie with the water heater.  Flushing the tank’s contents to remove sediment or replacing the sacrificial anode rod may solve this problem. If left unaddressed, this issue can worsen and lead to rust damaging the inside of the tank and ultimately the need for a new water heater. Consult a plumber to see what maintenance or repairs can be done to prolong the life of the water heater.\

4. Repairs Keep Adding Up –Are you calling for repairs to your water heater more than twice a year? If so, start planning your water heater replacement, and avoid the hassle of an emergency replacement.

5. Water Heater is Over 10 Years Old – An important question to ask yourself when deciding to replace your water heater is “How long has the water heater been in my house?” ENERGY STAR recommends replacing your storage water heater if it is over 10 years old. A decline in the performance of the water heater due to age is inevitable. Be proactive and replace it with an ENERGY STAR-certified water heater before it fails.

Water heater replacement may be costly upfront, but upgrading to an ENERGY STAR-certified, energy-efficient water heater can save you more money in long-term. In fact, ENERGY STAR natural gas storage and tankless water heaters use about 10 percent less energy compared to standard gas water heaters and can save your household hundreds of dollars over its lifetime.

Did you know, Washington Gas offers rebates to help you replace old water heaters and upgrade to new high-efficiency models. You can save up to $400 on a new ENERGY STAR certified water heater for your home. Through the Washington Gas Maryland Existing Home Program, Maryland customers can take advantage of natural gas appliance rebates. To qualify, eligible equipment must be purchased and installed by a qualified participating contractor in the Washington Gas EmPOWER Contractor Network. Get started by visiting WashingtonGasRebates.com/MDHome today.

If your contractor doesn’t take away your old hot water heater, make sure to dispose of your old one correctly by scheduling a curbside scrap metal pickup from your home or bringing it to the Transfer Station. Learn more at www.montgomerycountymd.gov/scrapmetal.

  1. I didn’t know that you should have your water heater replaced if it is over 10 years old since it can become less efficient over time. My uncle has owned his water heater for at least 13 years, and he isn’t sure if water heaters need to be replaced. I’ll let him know that he should find a service that can replace his water old water heater with one that will function more effectively.

  2. That was a good point that if your water starts to have a lack of sufficient hot water it might be time for a replacement. I’ve been having a hard time getting my shower as hot as I would like it to be and putting it on the hottest setting doesn’t even help. Maybe I should look into water heater replacement services and get a new system.

    It was helpful when you said that a sign could be a lack of hot water. Last night my daughter was complaining about how the shower would not get warm even when the shower handle was on the hottest temperature setting. I’ll have to look into calling a plumber to come and inspect it to see what’s wrong.

  5. These are all great reasons to replace a water heater. Having your appliance inspected by an experienced and qualified plumber will go a long way in letting you know what route to take.

      Thank you Water Heater Replacement Mason! We couldn’t agree more than working with an experienced and qualified plumber will go a long way in letting you know what route to take! If you have other energy saving tips and tricks, we would love to hear them!

  6. We planned to spend our vacation at my brother’s beach house this year and when we went to test if everything was working, some of the faucets didn’t seem quite right. I appreciate your article for stating that lukewarm water coming out when you expect hot water is a reason to get a replacement because every faucet in the house couldn’t make any water that was hotter than your usual tap water and I was thinking if this was just a coincidence or if it meant something more serious. I’ll be sure to get a plumber to check out the beach house and make any necessary replacements before vacation. Thank you!

    1. Larissa Johnson says:

      We are so glad that this helped you out! Hope you have an amazing summer vacation!

  7. My sister has been complaining that her water heart is producing an odd smell, and on top of that, it’s not producing enough hot water as well. I never knew that it’s possible to have rust and a metallic taste in the water heater, I’d make sure to check for any signs. Maybe it’s best if I’ll start looking for an installation service so they may proceed with the work.

    1. Larissa Johnson says:

      Rachel – please do get someone to look at the water heater – it is better to be overly cautious than to have to purchase something quickly! Let us know if you want to share your story about the process! Thank you 🙂

    Thanks to spreading this awesome content.

  9. I never knew that a failing water heater could release weird-colored water when using it. I called my mom recently and she mentioned that this, along with a distant odor, is coming from her water heater. I believe leaving this to an experts o that it’ll get repaired or replaced is a good idea.

    1. Larissa Johnson says:

      Yes, please do contact an expert and if you do replace your hot water heater, remember that Montgomery County has a $250 property tax credit program that you could apply to: https://www.montgomerycountymd.gov/Finance/Resources/Files/data/taxes/renewable_energy_tax_credit_application.pdf

  13. Luke Smith says:

    I like that you pointed out how leaks and corrosion could mean that the water heater has reached the end of its life and may be at risk of bursting. I was cleaning around our water heater tank the other day and I noticed that there are pools of water around it. That isn’t a good sign so we should probably call for water heater replacement services and have them work on our heater.

  14. Happy Hiller says:

    Thank you for sharing this information! I only want to add that rumbling is another sign that your water heater needs to be replaced. As time goes on, sediment builds up inside the water heater tank. As the water heater heats this up time after time, it becomes hard and starts to move around in the tank. This causes a rumbling noise.

  15. Please note that ten years is not an age of replacement for on-demand water heaters. While a storage water heater last 10 to 15 years, tankless heaters have a much longer life expectancy. You can expect your unit to last for more than 20 years.

  16. ESCO says:

    When replacing your water heater and choosing between the tank and tankless water heaters, remember that tankless heaters are 24–34 percent more energy-efficient than a traditional tank in households using less than 41 gallons of hot water daily. The only disadvantage is that such water heaters are more expensive to install.

  17. An old unit definitely feels like something that shouldn’t be kept around anymore of it isn’t efficient. Our water heater definitely feels like this, and I can see us benefitting from a unit that has more up-to-date features now that we take hot showers more often. I’ll take your advice and look for a plumbing service that can help us with a replacement water heater right away.

    It was really helpful when you said that water taking a long time to heat up is a bad sign.
