Signs it’s Time to Replace Your Water Heater

Water heaters are essential to maintaining home comfort. One day, you may wake up and go take a shower, only to find that you have inconsistent hot water. Not only is this an inconvenient way to start your day, but it can also mean it may be time to replace your water heater.
Water heaters wear out over time, and catching warning signs early can prevent major water damage or an emergency breakdown. Dauenhauer is the trusted local expert for water heater replacement and installation in Kentucky. We’re going to share seven signs it’s time to replace your water heater.
How Long Should a Water Heater Last?
The average lifespan of a water heater will depend on the type of unit you have and a few other factors. Traditional tank water heaters last, on average, 8-12 years. Tankless water heaters last closer to 15-20 years.
Other factors that affect a water heater’s lifespan include maintenance habits, installation quality, and hard water presence. In Kentucky, hard water is very common and can cause increased wear and tear on water heaters.
If your water heater is within or past the average lifespan range, it’s time to watch for the following warning signs.
Sign #1 – Your Water Heater Is Leaking
If you notice water pooling around the base of your water heater, it’s a major red flag. Your water heater may be leaking due to internal tank corrosion, which unfortunately, cannot be repaired. You should replace your water heater as soon as you notice its leaking. Delaying replacement risks flooding of your home and mold damage.
Sign #2 – Inconsistent or Insufficient Hot Water
If your hot water turns cold quickly, especially during morning or night routines, you may need water heater replacement. Possible causes of inconsistent or insufficient hot water include a failing heating element, sediment buildup, or declining tank capacity. In these cases, it is often more cost-effective to replace your unit rather than repeatedly repair it.
Sign #3 – Rusty or Discolored Water
Rusty or discolored hot water can indicate internal rank corrosion, which ultimately means it’s time to replace your unit. If rust only appears in hot water, this means it is coming from the tank vs. your pipes. If your water is discolored when running hot and cold, it could be an issue with your pipes.
Sign #4 – Strange Noises from the Unit
Strange noises are always a cause for concern. Rumbling or popping noises can indicate sediment buildup at the bottom of your tank. This buildup forces the burner or heating element to work overtime. The noises come from small steam pockets bursting through the layer of sediment. Long-term sediment damage often leads to full replacement.
Sign #5 – Rising Energy Bills
If you’ve noticed rising energy bills without increased water use, your model may be getting old and less efficient. It’s common for older water heaters to lose efficiency over time. This means that more energy is required to heat the same amount of water, reflected in higher utility bills. Replacing your water heater improves efficiency and lowers monthly energy costs.
Sign #6 – Your Water Heater Needs Frequent Repairs
If you’re frequently calling for repairs every few months, replacing your water heater can be more economical. Water heater repairs can be expensive if you need frequent service. Compare the cost of ongoing repairs vs. the cost of a new system to see when it’s time to replace your unit. Often, the cost of a new unit is less than ongoing repair costs for an aging water heater.
Sign #7 – Visible Corrosion on the Tank
Noticing exterior corrosion or rust is never a good sign for your water heater. Visible corrosion on the tank indicates structural deterioration and means a replacement unit is necessary. Once tank material breaks down, replacement is the only safe option. Avoid the risk of flooding and water damage to your property by addressing the issue promptly.
