Signs You Need to Repair Your Electric Water Heater
Your water heater is one of those appliances you probably don’t think about until something goes wrong. A cold shower on a chilly morning is a rude awakening, but thankfully, most water heaters give you a few warning signs before they completely give up. Paying attention to these clues can help you catch a small problem before it turns into a major, floor-soaking emergency. Think of it as a little health check-up for your home’s plumbing.
From strange noises coming from the tank to water that just isn’t getting hot enough, these signs are your water heater’s way of asking for help. Some issues are simple fixes, while others might point to a more serious problem that needs a professional’s touch. Knowing what to look for will help you decide your next move, whether it’s a quick DIY adjustment or a call to the experts. Let’s walk through the five most common signs that your electric water heater needs a repair.
No Hot Water or Fluctuating Temperatures
This is the most obvious sign that something is wrong. If you turn on the tap and get nothing but cold water, the cause could be as simple as a tripped circuit breaker. It could also point to a more complex issue, like a faulty heating element or a tripped high-temperature cutoff switch. Another tell-tale sign is when your hot water runs out much faster than it used to. If your family can’t get through their morning showers without the water turning icy, it’s a strong indicator that one of the heating elements isn’t working correctly and your unit is struggling to keep up with demand.
Hearing Strange Noises or Feeling Vibrations
Your water heater should operate almost silently. If you start hearing popping, rumbling, or whining sounds, it’s time to pay attention. These noises are usually caused by sediment—a collection of minerals and debris—that has built up at the bottom of your tank. As the heating elements turn on, they have to heat the water through this layer of gunk, which can cause the water to boil and create those strange sounds. This sediment buildup not only makes your heater less efficient but can also lead to overheating and long-term damage to the tank. A professional residential drain cleaning service can often resolve sediment issues in your pipes and heater.
Finding Leaks or Moisture
Water pooling around the base of your water heater is a major red flag that demands immediate action. Even a small amount of moisture can signal a serious problem. While the leak could be coming from a fitting or the pressure relief valve, it often indicates that the internal tank has started to corrode and crack. Unfortunately, a leaking tank can’t be repaired; it means the entire unit needs to be replaced. Ignoring a leak can lead to significant water damage to your floors, walls, and foundation, so it’s crucial to address it right away. If you see water, it’s best to schedule service with a professional immediately.
Noticing Discolored or Smelly Water
The water coming from your hot water taps should be clear and odorless. If you notice rusty, brown, or yellowish water, it’s a sign that the inside of your water heater tank is corroding. That discolored water is actually rust from the tank mixing with your water supply. Another unpleasant sign is water that smells like rotten eggs. This is typically caused by bacteria that can grow inside the tank. While not always a sign of imminent failure, both discolored and smelly water indicate that your water heater needs attention, likely a thorough flushing or a replacement of the anode rod.
Seeing a Spike in Your Energy Bill
A sudden, unexplained increase in your electricity bill can sometimes be traced back to a struggling water heater. As a water heater ages and its components wear out, it becomes less efficient. Sediment buildup can force the heating elements to work harder and longer to heat the water, consuming more energy in the process. A faulty thermostat can also cause the unit to run constantly. If your energy usage is creeping up without any other explanation, it’s worth inspecting your water heater. It might be a sign that the appliance is nearing the end of its life and that a more energy-efficient model would be a smarter investment.
Gather Your Tools and Prioritize Safety
Before you roll up your sleeves and get to work, let’s talk about the most important part of any DIY project: preparation and safety. I know it’s tempting to jump right into the repair, but taking the time to gather your tools and understand the safety steps isn’t just a suggestion—it’s essential. A successful repair is one that you walk away from feeling accomplished, not one that ends with a frantic call to an emergency service. Think of this section as your pre-flight checklist. By following these steps, you’re setting yourself up for a smooth process and ensuring that you, your home, and your water heater stay safe. We’re dealing with a combination of water and electricity, so there’s no room for cutting corners. Let’s walk through exactly what you need and what you need to do before you even touch a single wire or valve.
Your DIY Repair Toolkit
Having the right tools ready to go will make the entire repair process feel less like a chore and more like a puzzle you’re equipped to solve. You don’t need a professional-grade setup, but a few key items are non-negotiable. First, grab a multimeter for testing electrical currents—this is your best friend for diagnostics. You’ll also need a basic set of screwdrivers (both Phillips and flathead) and a pair of pliers. It’s also wise to have an old bucket and some towels handy for any residual water. When it comes to replacement parts like heating elements or thermostats, always buy components that are specifically designed for your water heater’s make and model. Using generic parts might seem like a way to save a few dollars, but they can cause serious damage and void your warranty.
Essential Safety Gear
This part is simple: your safety comes first. Working on any appliance that combines water and electricity demands respect and the right protective gear. Start with a good pair of insulated gloves to protect your hands from electric shock and safety goggles to shield your eyes from any unexpected splashes or debris. It’s also a good idea to wear sturdy, closed-toe shoes to protect your feet. Keep your work area as dry and clutter-free as possible. While many repairs are straightforward, it’s important to recognize when a problem is beyond a simple fix. If you encounter complex wiring issues or a significant leak, it’s always the smartest and safest choice to stop and schedule a service call with a professional.
How to Safely Turn Off the Power
This is the most critical step in the entire process, and you should never, ever skip it. Before you open any access panels or touch any components, you must completely cut the power to the water heater. Don’t rely on the unit’s thermostat switch. You need to go to your home’s main electrical panel, find the circuit breaker dedicated to the water heater (it should be labeled), and flip it to the “OFF” position. For extra peace of mind, you can place a piece of tape over the breaker to prevent anyone from accidentally turning it back on while you’re working. Then, use your multimeter to test the wires at the heater to confirm there is no electrical current.
How to Shut Off the Water Supply
With the power safely off, your next move is to stop water from flowing into the tank. Locate the cold water inlet pipe, which is typically found on the top of your water heater. You should see a shut-off valve on this pipe with either a wheel-style or lever-style handle. Turn the handle clockwise all the way until it stops. This will prevent the tank from refilling as you work, which is crucial for avoiding a messy situation. If the valve is stuck or seems difficult to turn, don’t force it. Instead, you can shut off the main water supply to your entire house. This extra step ensures a simple repair doesn’t turn into an unexpected indoor flood.
What to Do in an Emergency
Even with the best preparation, unexpected issues can arise. It’s important to know how to react if things don’t go as planned. If you see sparks, smell something burning, or notice a leak that’s quickly getting worse, your priority is to ensure your safety. For any electrical emergency, leave the area immediately and don’t touch anything. For a major water leak, shut off the main water supply to your house if you haven’t already. Don’t try to be a hero—your well-being is far more valuable than any appliance. In these situations, it’s time to call in the experts. Our team is always ready to handle any plumbing emergency, from a burst tank to a major residential sewer pipe repair.
What’s Inside Your Water Heater?
Before you can tackle a repair, it helps to know what you’re working with. Think of your electric water heater as a simple system with a few key players working together to deliver that hot shower you love. Getting familiar with these parts will make it much easier to figure out what’s gone wrong and what it’ll take to fix it. From the components that do the heating to the features that keep you safe, here’s a look inside your water heater.
Heating Elements and Thermostats
The heart of your electric water heater lies in its heating elements and thermostats. Most tanks over 20 gallons have two of each: one at the top and one at the bottom. The thermostats act like thermometers, constantly monitoring the water temperature. When the water cools down, the thermostat signals the heating element—a metal rod that gets hot—to turn on and warm the water back up. The upper thermostat and element usually kick on first, heating the top portion of the tank. Once that’s done, the lower duo takes over to heat the rest. This tag-team approach ensures you have a full tank of hot water ready when you need it.
Built-in Safety Features
Your water heater is designed with your safety as a top priority. One of the most important safety devices is the high-temperature limit switch. This feature acts as a fail-safe, automatically cutting power to the heating elements if the water gets dangerously hot, typically around 150°F. This prevents the unit from overheating, which could otherwise create a serious hazard. It’s a simple but critical component that works behind the scenes to give you peace of mind, ensuring your system operates safely without you ever having to think about it.
Pressure Control Systems
Water expands when it heats up, which creates pressure inside the tank. To manage this, every water heater is equipped with a temperature and pressure relief valve, or TPR valve. If the pressure or temperature inside the tank climbs too high, this valve automatically opens to release some water and relieve the pressure. This is a crucial safety feature that prevents the tank from rupturing under extreme conditions. You’ll usually see a pipe leading from this valve down the side of the tank, which is where the water would safely drain.
Parts That Wear Out First
Like any hardworking appliance, some parts of your water heater will wear out faster than others. The heating elements and thermostats are often the first components to fail, simply because they do the most work. Another common issue is sediment buildup. Over time, minerals from your water supply can settle at the bottom of the tank, forming a layer of sediment. This can insulate the lower heating element, forcing it to work harder and eventually burn out. If you notice signs of wear, it might be time to schedule a service to have these parts inspected or replaced.
Energy Efficiency Components
Modern water heaters are built to be more energy-efficient than older models, helping you save on your utility bills. The biggest factor here is insulation. A thick layer of foam insulation surrounds the tank, minimizing heat loss so the water stays hot longer without the heating elements constantly turning on. Additionally, today’s heating elements are designed to heat water more effectively, using less electricity to get the job done. Keeping your tank free of sediment also plays a role, as it allows the heating elements to transfer heat to the water efficiently.
How to Troubleshoot Common Problems
When your water heater acts up, a little detective work can go a long way. Before you panic, walking through a few simple checks can often pinpoint the problem. Many common issues have straightforward causes that you can identify on your own. From power supply interruptions to simple thermostat adjustments, these troubleshooting steps will help you figure out what’s going on with your unit. Remember, safety is always the first step, so make sure you’ve turned off the power and water before you start investigating. This guide will walk you through the most frequent culprits behind water heater trouble, helping you decide if it’s a quick fix or time to call in the experts.
Check for Power and Circuit Issues
If you suddenly have no hot water, the first place to check is your home’s electrical panel. It’s a simple fix, but a tripped circuit breaker is a common reason for an electric water heater to stop working. Find the breaker dedicated to your water heater and see if it’s in the “off” or middle position. If it is, flip it back to “on.” If it trips again right away, leave it off and call a professional, as this indicates a more serious electrical problem. Before touching any part of the water heater itself, always shut off the power at the breaker box to be safe.
Solve Temperature Control Problems
Is your water scalding hot or just lukewarm? The issue likely lies with the thermostats. Most electric water heaters have two—one for the upper heating element and one for the lower. After turning off the power, you can remove the access panels to find them. Check that they are set to the same temperature, typically around 120°F for safety and efficiency. If the water is too hot, the setting might be too high. If it’s not hot enough, one or both of your heating elements could have failed. Adjusting the temperature is simple, but if that doesn’t solve it, you may need a new element or thermostat.
Address Water Quality Concerns
If your hot water comes out looking rusty or smelling like rotten eggs, your water heater tank is sending you a clear signal. Brown, yellow, or reddish water usually means the inside of your tank is corroding. That unpleasant rotten-egg smell is often caused by bacteria that can grow inside the tank. Flushing the tank can sometimes help with these issues, but severe rust means the tank’s integrity is compromised. If you notice persistent water quality problems, it might also be a sign of wider issues in your pipes that require professional residential drain cleaning services.
Inspect Pressure and Valve Issues
A critical safety component of your water heater is the temperature and pressure relief (T&P) valve. It’s designed to release pressure if it gets too high inside the tank. If you notice a slow, steady drip from this valve, it could be faulty or signaling that the pressure is too high. Also, check the plumbing connections at the top and bottom of the unit. A leak from the cold water inlet or hot water outlet pipe might just require tightening a connection. However, constant dripping from the T&P valve is a problem you shouldn’t ignore, as it’s there to prevent a dangerous pressure buildup.
Find the Source of a Leak
Water pooling around the base of your heater is a major red flag. First, try to find where the water is coming from. It could be a loose pipe fitting or a leaking T&P valve, which are often fixable. However, if you see water seeping from the tank itself, it means the inner tank has rusted through or cracked. Unfortunately, this is not a repairable problem; the entire unit needs to be replaced. If you discover a leak coming from the tank, turn off the water and power immediately and schedule service with a professional to prevent a major flood and water damage.
Your Step-by-Step Repair Guide
Okay, you’ve identified the problem, you have your tools, and you’ve taken all the safety precautions. Now it’s time to get to work. This guide will walk you through some of the most common electric water heater repairs you can tackle yourself. Remember, every model is slightly different, so it’s always a good idea to have your owner’s manual handy for specific instructions. Approaching a repair with confidence is half the battle, but it’s just as important to know your limits. While these steps can help you solve many issues, some problems are more complex and require professional expertise. If you ever feel unsure, the problem seems bigger than you expected, or you run into a snag, it’s always safest to stop what you’re doing. Don’t hesitate to schedule a service call with a trusted plumber. Your safety and a properly functioning water heater are the top priorities. Let’s get started on these common fixes.
Replace a Faulty Heating Element
The heating elements are the workhorses of your electric water heater, responsible for actually heating the water. If your water is lukewarm or completely cold, a burnt-out element is a likely culprit. When you’re replacing one, it’s crucial to use the correct parts specifically designed for your model. Using generic or mismatched parts can damage your water heater and even void its warranty, turning a simple fix into a costly mistake. The process involves turning off the power, draining the tank below the element’s location, unscrewing the old element, and installing the new one with a fresh gasket. Make sure the new element is seated properly to prevent leaks before you refill the tank and restore power.
Repair or Replace the Thermostat
Your water heater’s thermostat acts as its brain, telling the heating elements when to turn on and off. If your water temperature is unpredictable—sometimes scalding, sometimes cold—the thermostat might be failing. A malfunctioning thermostat can cause everything from an inadequate hot water supply to strange noises as the elements cycle incorrectly. You can test it with a multimeter to see if it’s getting power and sending it correctly. If the thermostat is malfunctioning, it may need to be repaired or replaced to restore proper function. After cutting the power, you’ll disconnect the wires, remove the old thermostat, and install the new one, making sure to connect the wires exactly as they were.
Fix Minor Leaks
A small puddle under your water heater can be alarming, but it doesn’t always mean disaster. Minor leaks from fittings or the pressure relief valve can often be fixed with simple adjustments. You might just need to tighten a connection or replace a worn-out washer or seal. The most important step is to always turn off the power and the water supply before you start any work. A small drip can sometimes be a sign of a bigger problem, like a corroded tank, so carefully inspect the source. If the leak is coming from the tank itself, it’s time to call a professional immediately, as this usually means the unit needs to be replaced.
Remove Sediment Buildup
Over time, minerals from your water supply can settle at the bottom of your tank, creating a layer of sediment. This buildup forces your heating elements to work harder, reducing efficiency and making strange popping or rumbling noises. Flushing the water heater regularly can help prevent sediment buildup, which can affect the efficiency and lifespan of your unit. It’s recommended to perform this maintenance task at least once a year. The process involves shutting off the power and cold water inlet, connecting a hose to the drain valve, and letting the water run out until it’s clear. This simple task can significantly improve your heater’s performance and extend its lifespan.
Change the Anode Rod
Think of the anode rod as a bodyguard for your water heater’s tank. This metal rod is designed to corrode so that your steel tank doesn’t. The anode rod is a critical component that helps protect the tank from rust, and because it sacrifices itself, it needs to be checked every couple of years. Regularly checking and replacing the anode rod can significantly extend the life of your water heater. The replacement process involves shutting off the water, draining a few gallons from the tank, and unscrewing the old rod to install a new one. This is one of the most effective ways to prevent a catastrophic tank failure and keep your water heater running for years to come.
Keep Your Water Heater Running Smoothly
A little bit of maintenance can make a huge difference in how well your water heater performs and how long it lasts. Think of it as a quick health check-up for one of the hardest-working appliances in your home. By spending a small amount of time on it each year, you can catch minor issues before they become major, expensive emergencies. These simple steps will help you save money on energy bills, avoid unexpected cold showers, and extend the life of your unit. It’s all about being proactive, and you don’t have to be a plumbing expert to handle these basic tasks.
Your Regular Inspection Checklist
Once a year, take a few minutes to give your water heater a good look-over. Start by checking for any signs of moisture or small drips around the base of the tank and at the pipe connections on top. Look for rust or corrosion, which can indicate a slow leak or a problem with the tank itself. You should also listen for any unusual sounds like popping or rumbling while it’s heating—this often points to sediment buildup inside. Finally, if your hot water doesn’t seem to last as long as it used to, the heating elements might be failing. Catching these things early can prevent a sudden breakdown.
How to Flush the Tank
Over time, minerals and sediment from your water supply settle at the bottom of your water heater tank. This layer of gunk forces your heater to work harder to warm the water, which wastes energy and can cause the tank to overheat and fail prematurely. Flushing the tank once a year is the best way to clear out this buildup. While it’s a task some homeowners tackle themselves, it can be messy. If you’re not comfortable doing it, you can always schedule service with a professional to ensure it’s done correctly and without any hassle. This simple step keeps your heater running efficiently and helps it last for years.
Optimize Your Temperature Settings
Most water heaters are set to 140°F by default, but for most households, that’s unnecessarily high. Lowering the temperature to 120°F is a great way to save on your energy bill—you can cut water heating costs by up to 10%! It also reduces the risk of scalding, which is especially important if you have kids or elderly family members at home. Before you make any adjustments, be sure to turn off the power to the water heater at your circuit breaker. Then, you can safely adjust the dial on the thermostat. It’s a small change that offers big benefits for both your wallet and your family’s safety.
Test the Pressure Relief Valve
Your water heater’s temperature and pressure (T&P) relief valve is a critical safety feature. If the pressure inside the tank gets too high, this valve automatically opens to release it, preventing a potential explosion. Because it’s so important, you should test it once a year to make sure it hasn’t gotten stuck. To do this, place a bucket under the discharge pipe, then briefly lift the valve’s lever. A burst of hot water should come out. If it only trickles out or doesn’t release any water at all, the valve needs to be replaced immediately. This is a job best left to a professional to ensure your system remains safe.
Prevent Future Leaks
Even a tiny leak can lead to significant water damage over time, so it’s wise to be proactive. During your annual inspection, check all the plumbing connections going into and out of the water heater. If you spot any drips, you can sometimes stop them by simply tightening the connection with a wrench. If you’re dealing with persistent problems, like water that never gets hot enough or runs out too quickly, it might be a sign that your unit is on its last legs. Instead of paying for repeated fixes, it might be more cost-effective to consider a replacement. An expert can help you weigh your options for any residential sewer pipe repair or replacement needs.
Know Your Limits: When to Call a Pro
While tackling a DIY project can be incredibly satisfying, your home’s plumbing system isn’t the place for guesswork. Water heaters, especially, combine water, high pressure, and electricity, a trio that demands respect and expertise. Pushing past your comfort zone can lead to bigger, more expensive problems, property damage, or even serious injury. Knowing when to put down the wrench and pick up the phone is a crucial part of being a smart homeowner.
Think of it this way: a professional plumber has spent years training to handle these systems safely and efficiently. They have the specialized tools and diagnostic equipment to pinpoint the exact cause of a problem, saving you hours of frustration. More importantly, they understand local building codes and safety protocols. When you’re dealing with a major leak, complex electrical wiring, or a tank that’s about to fail, calling an expert isn’t admitting defeat—it’s making the wisest and safest choice for your home and family. A professional can offer peace of mind that the job is done right the first time.
Signs It’s Time to Call an Expert
Some water heater issues are clear signals that a DIY fix is off the table. If you notice the tank itself is rusted or actively leaking, don’t hesitate to call for help. A leaking tank almost always indicates a critical failure that requires a full replacement. Another major red flag is the quality of your water. If it comes out rusty, discolored, or has a foul odor, it could point to corrosion inside the tank or a bacterial problem. Finally, trust your gut. If you’ve opened up the access panel and the wiring looks too complicated, it’s always better to schedule service with a professional.
Repairs Best Left to Professionals
Certain repairs carry significant risks and should always be handled by a licensed plumber. Anything involving complex electrical work, like replacing the main wiring or addressing issues with the circuit breaker connection, is a non-negotiable call to a pro. If you have a gas water heater, any work on the gas lines, valves, or exhaust vents requires an expert. If you hear loud popping, banging, or rumbling noises from the tank, it could be a sign of extreme sediment buildup causing overheating or a failing heating element. These situations can compromise the tank’s integrity, so it’s best to let an expert diagnose and handle the problem safely.
Understanding Repair Costs
Before you decide whether to repair or replace your water heater, it helps to have a general idea of the costs. A professional repair for a standard tank-style water heater can run anywhere from about $225 to nearly $1,000, depending on the part that needs fixing and the labor involved. For example, replacing a thermostat is much less expensive than replacing both heating elements. On the other hand, a full replacement can range from $600 to over $2,500. While that’s a bigger upfront investment, it might be the more cost-effective choice if your current unit is old or requires frequent, expensive repairs.
What to Do in a Plumbing Emergency
If you walk into your garage and find water pooling around the base of your water heater, stay calm and act quickly. Your first step is to shut off the water supply to the tank to prevent further flooding. Next, turn off the power to the water heater at your circuit breaker box. Once you’ve contained the immediate threat, your next call should be to an emergency plumber. A major leak from the tank itself is a clear sign that the unit has failed and needs to be replaced immediately. Don’t wait for it to get worse—getting a professional on-site quickly can prevent extensive water damage to your home.
Decide Between Repairing vs. Replacing
So, how do you make the final call between repairing and replacing? Start with the age of your water heater. Most tank-style heaters have a lifespan of about 10 years. If your unit is approaching that age, investing a few hundred dollars in a repair might not be worth it, as another part could fail soon. Also, consider the frequency of repairs. If you’re calling a plumber every year for a new issue, those costs add up. It’s likely more economical in the long run to put that money toward a new, more reliable, and energy-efficient model. A good rule of thumb: if a repair costs more than 50% of a replacement, it’s time for a new unit.
How to Make Your Water Heater Last Longer
A little proactive care can make a huge difference in how long your water heater lasts. Instead of waiting for a cold shower to tell you something’s wrong, you can take a few simple steps to extend its life, improve its efficiency, and save money on future repairs. Think of it as a small investment of your time that pays off with years of reliable hot water. Most of these tasks are straightforward, and getting into a routine with them will help you catch small issues before they turn into major headaches. By paying attention to your unit’s performance and keeping up with basic maintenance, you can keep it running smoothly for years to come. From simple temperature adjustments to knowing what sounds are normal and which ones aren’t, being an informed owner is your best defense against unexpected breakdowns. This isn’t about becoming a master plumber overnight; it’s about understanding the basics so you can maintain your appliance effectively and know when it’s time to call in a professional.
Set Up a Regular Maintenance Schedule
The single best thing you can do for your water heater is to give it regular attention. Even new units require consistent maintenance to perform at their best and last as long as possible. A simple annual check-in can prevent sediment buildup, corrosion, and other common problems that shorten a heater’s lifespan. This includes flushing the tank to clear out mineral deposits and inspecting the anode rod, which is designed to corrode so your tank doesn’t. Putting these tasks on your calendar helps ensure they get done. If you’d rather leave it to an expert, you can always schedule a service with a professional to handle the inspection for you.
Optimize for Energy Efficiency
Your water heater’s temperature setting affects both your energy bill and the unit’s longevity. Most manufacturers set the thermostat to 140°F, but keeping the water temperature at 120°F or lower can help save energy and reduce the risk of scalding. This simple adjustment also slows mineral buildup and corrosion inside the tank, reducing the strain on the heating elements. A lower temperature means the unit doesn’t have to work as hard, which can extend its life. If your water heater is struggling to maintain a consistent temperature, it might be a sign that it needs a professional look.
Know When to Replace Key Parts
Hearing that your water heater has a problem doesn’t automatically mean you need to buy a new one. In fact, many hot water issues are repairable. Problems like faulty thermostats, broken heating elements, and sediment buildup can often be fixed without replacing the entire unit. This same sediment can also cause issues in your pipes, which is why regular residential drain cleaning services are also a good idea for home maintenance. The anode rod is another critical component designed to be replaced every few years to prevent tank corrosion. Understanding which parts are replaceable can save you hundreds of dollars.
Monitor Your Heater’s Performance
Pay attention to the signals your water heater sends you. If you notice discolored water or strange noises, these could be signs of underlying issues that need to be addressed. Popping or rumbling sounds often point to sediment buildup, while discolored water can indicate rust. Small puddles or moisture around the base are clear signs of a leak that needs immediate attention. If left unchecked, even a small leak can lead to significant water damage and might require extensive work like trenchless pipe repair if it affects pipes under your foundation. Catching these problems early gives you the best chance of fixing them before they cause serious damage.
Simple Energy-Saving Tips
Beyond adjusting the thermostat, a few other tricks can help your water heater run more efficiently. Insulating your hot water pipes can reduce heat loss as water travels from the heater to your faucet, meaning you don’t have to wait as long for it to warm up. This simple step ensures the heat stays in the water instead of escaping into your walls. You can also purchase a water heater blanket to wrap around the tank for extra insulation, though you should check your owner’s manual first to make sure it’s recommended for your model. These small changes reduce energy consumption and lighten the workload on your heater.

Why would my energy bill suddenly go up? Is my water heater the cause? Yes, a struggling water heater is often the reason for a surprise spike in your electricity bill. As parts wear out or sediment builds up, the unit has to work much harder and run longer to heat the same amount of water. This inefficiency directly translates to higher energy consumption. If you can’t explain the increase in your bill, it’s a good idea to have your water heater inspected.
