How To Know if You Need a New Water Heater

Troubleshooting Shower Heaters

Are you experiencing lukewarm showers despite cranking the faucet to its hottest setting? Or have you noticed peculiar noises coming from your basement? These signs indicate that something might be amiss with your water heater.

A malfunctioning water heater can throw a wrench into your daily routine, but how do you know if it’s time to say goodbye to your old water heater and buy a new one? 

This blog post will explore how to know if you need a new water heater. We’ll also discuss the importance of hot water heater installation and repair services in Pacifica, CA.

Understanding the Signs

Crucial Signs of Broken Heater

To determine if your water heater is nearing the end of its life, here are some common signs to look out for.


The average lifespan of a water heater usually ranges from 7 to 12 years, depending on the type and maintenance. If your water heater is near or over this age range, it’s wise to consider a replacement, even if it still functions adequately. Older heating units are more prone to inefficiencies and breakdowns, leading to higher energy bills and potential water damage.

Rusty Water

Rusty or discolored water from your faucets is a clear indicator of corrosion within your water heater tank. This discoloration could signify that your unit is deteriorating from the inside out, potentially leading to leaks or a complete breakdown. If you notice rusty water, it’s crucial to consult with a professional water heater repair service provider for inspection and potential replacement.

Metallic Smell and Taste

Like rusty water, a metallic smell or taste in your hot water could indicate that the interior of your tank is deteriorating. This issue could be a sign of high levels of minerals in your water supply, which can cause damage to your water heater over time. Corrosion from sediment buildup usually can cause this metallic taste, potentially leading to health hazards if left unaddressed.

Lack of Hot Water

Are you constantly running out of hot water, or is your water never reaching the desired temperature? These signs could indicate a failing heating element or sediment buildup within the tank, which can significantly reduce your water heater’s efficiency. In such cases, investing in a new water heater can restore a consistent hot water supply and improve energy efficiency.

Strange Noises

A properly functioning water heater should operate quietly. If you hear rumbling, popping, or banging noises from your unit, it’s likely due to sediment accumulation at the bottom of the tank. Over time, sediment buildup can hinder heat transfer and lead to premature wear and tear on the tank.


Visible leaks around your water heater clearly indicate a problem that requires immediate attention. Whether it’s a minor drip or a major puddle, leaks can lead to water damage, mold growth, and structural issues if left unaddressed. In such cases, it’s crucial to seek professional water heater repair services or consider a replacement, depending on the severity of the issue.

High Energy Bills

Water heating takes up only about 18% of the total energy usage in a typical household. However, inefficient or malfunctioning units can significantly increase this percentage. If you notice a sudden spike in your energy bills without any lifestyle changes or increased water use, it could be a sign that your water heater is struggling to operate efficiently and may need to be replaced. 

Importance of Professional Services
