Is It Time to Replace Your Hot Water Heater?

Mahon Plumbing Replace Hot Water Heater

How do you know when it’s time to replace your hot water heater? Here are some signs that it’s about that time.

Your hot water heater is a crucial appliance in your home, providing you with a steady supply of hot water for various daily tasks. Whether it’s for a relaxing hot shower, doing dishes, or washing your hands, a functioning hot water heater is essential. However, like all appliances, hot water heaters have a limited lifespan and may require replacement at some point.

Age Matters

Hot water heaters are not designed to last forever. On average, a traditional tank-style water heater can last anywhere from 8 to 12 years, while tankless water heaters have a longer lifespan of around 20 years. If your water heater is approaching or has exceeded these age ranges, it’s a clear sign that you should consider replacing it. Older units tend to become less efficient and more prone to leaks and other issues.

Declining Efficiency

As water heaters age, they tend to become less efficient. This means they will consume more energy to heat the water to the desired temperature. You might notice higher utility bills as a result. If you’re experiencing a sudden increase in your energy bills without a clear explanation, it might be time to check the efficiency of your hot water heater. Upgrading to a more energy-efficient model can save you money in the long run.

Rust and Corrosion

Rust and corrosion are common problems in water heaters, particularly in areas with hard water. If you notice rust-colored water coming from your faucets or you see visible signs of corrosion on the tank, it’s a clear indication that your water heater is deteriorating. Rust and corrosion can lead to leaks, and once the tank starts leaking, replacement is the best solution.

Strange Noises

Hot water heaters often make some noise during operation, but if you start hearing unusual or loud sounds, it could be a sign of trouble. Common noises that indicate issues include popping, cracking, or rumbling sounds. These noises can be due to sediment buildup in the tank, which reduces efficiency and can lead to overheating. In some cases, the sediment can damage the tank, necessitating a replacement.


Leaks from a hot water heater are a serious issue. A leaking tank can cause water damage to your home, leading to costly repairs. If you see water pooling around the base of your water heater or signs of water damage on the floor, it’s essential to address this issue immediately. Repairs may be possible in some cases, but if the tank is damaged, replacement is the safest course of action.

Inadequate Hot Water Supply

If you’ve noticed a decrease in the amount of hot water available for your daily needs, even after adjusting the temperature settings, your hot water heater may be failing. Inadequate hot water supply is a sign that the heating elements or the tank itself is not functioning properly. Upgrading to a larger or more efficient unit can ensure you have a sufficient supply of hot water when you need it.

Repetitive Repairs

Frequent repairs are a clear indication that your water heater is nearing the end of its life. If you find yourself calling a technician for repairs multiple times a year, it might be more cost-effective to invest in a new unit. Continually repairing an old water heater can add up, and the inconvenience of repeated breakdowns can be frustrating.
