Hot Water Heater Repair Cost

The average cost to repair a water heater in the United States is $587. The usual range for repairs is between $220 and $954, while homeowners have paid as little as $100 and as much as $1,300 on their repairs. When you wake up in the middle of a frosty winter morning and find yourself in the middle of a cold shower because your water heater is on the fritz, or worse, has entirely died, there is nothing worse. Because conventional, tank-type water heaters are very basic and uncomplicated in their operation, there are only a few things that may go wrong with them.

As the water heats up, the pressure within the tank increases.

  1. Simple issues such as a blown pilot light, a tripped circuit breaker, or a malfunctioning thermostat can cause significant damage.
  2. The majority of other repairs are also reasonably priced.
  3. A gas unit operates by the use of a gas flame, whereas an electric unit operates through the use of electric components or coils.
  4. A gas unit will be more expensive to install and replace, but it will use less energy over the course of its life than an electric unit.

Gas Water Heater Repairs

Models powered by natural gas will experience challenges that are specific to their power source. The three most common issues are with the pilot light, the thermocouple, and the gas control valve. They are listed in no particular order. A specialist will need to troubleshoot each piece of your problem one by one in order to determine the source of the problem. Generally, plumbers charge between $45 and $150 per hour, and the most typical problems with gas units cost between $150 and $500 to repair or replace.

Before you attempt to relight a pilot light or do repairs on your own, be certain that you are comfortable dealing with gas and that there are no strong gas odors in the vicinity of your unit before proceeding.

Pilot Light Assessment and Reignition Cost

An issue that occurs frequently with gas units is the failure of the pilot light to illuminate. If this is the case, it is possible that no repairs will be required. It’s possible that it was blown out or that your unit’s gas connection was disconnected for a short period of time. If you follow the proper methods, you should be able to relight this component by yourself.

This would spare you from having to pay a service call charge, which might run from $45 to $150 per hour depending on the company. If the light does not illuminate, you may have a problem with the thermocouple or the valve.

Thermocouple Replacement Cost

The cost of hiring a professional plumber to install a new thermocouple should be limited to $150 or less. If you conduct the job yourself, you will only be responsible for the cost of the part, which is around $20. The thermocouple is in charge of detecting the presence of a pilot light and triggering the gas control valve to continue delivering gas to the pilot light area. When this component fails, the control valve will no longer be able to reliably detect the existence of a flame, and the gas will no longer be released.

When your thermocouple quits operating, the only thing you can do is replace the device.

Gas Control Valve Replacement Price

If your pilot light and thermocouple are in good working order, it’s possible that you’ll need to replace your gas control valve. When this component fails, replacing it is typically a more efficient and cost-effective choice than repairing it in this situation. It is the control valve’s responsibility to release gas and switch off the pilot light when the pilot light is not lit. A faulty valve might cause your entire machine to become dangerous. If your burner or pilot light won’t ignite or remain lit, and after issues with the thermocouple and pilot light itself have been checked out, call a professional to identify the problem.

Cost of Installing New Gas Thermostat

Due to the fact that the thermostat is a component of the valve unit, replacing or repairing it will necessitate replacing or repairing the complete valve. A burner that fails to light is one of the most prevalent signs of a broken thermostat. The average cost of avalve unit is $80 dollars.

When it comes to these units, tripped breakers and faulty heating components are the most often encountered problems. It is possible to handle a tripped breaker without the assistance of an electrician. Unless you’re having problems with a blown breaker, you’ll want to check both the thermostats and the heating components.

Heater Element Replacement Cost

Please keep in mind that this equipment receives a very high voltage of electricity and that it can be extremely dangerous to operate. You must be certain that the electricity to your unit has been turned off before performing any tests or repairs on your own. The normal expert fee for repairing your heating components is from $200 to $300 per hour. In each unit, there are two of them, one at the top and one at the bottom of the unit. The top element is in charge of controlling the bottom element, and if it fails, your device will be unable to create hot water.

Thermostat Replacement

The cost of hiring a professional to remove an old thermostat and replace it is between $150 and $200. The individual components might cost up to $20. Each heating element has its own thermostat, which is controlled by the thermostat.

The problem is most likely one or two failing thermostats if you or your plumber discover that all of the parts are in proper operating condition. These may be simply replaced without the need to remove the actual pieces themselves.

Have a Pro DiagnoseFix the Issue

Instead of the traditional gas or electric water heater, your home may be equipped with a hot water heater, often known as a boiler. Boiler repairs cost an average of $350 and have difficulties that are comparable to those seen with conventional systems. Most likely, you have an indirect system, which allows your gas or electric boiler to simultaneously serve as a water heater for your residence. These systems are more energy efficient, and thus are considered a “green” alternative to traditional systems.

  • Electrical tripped breaker or blown fuse: $20 per breaker or fuse. When a breaker or fuse is broken, most homeowners can identify the problem themselves by inspecting the fuse box. Repairs for a pilot light that has gone out (gas) go from $45 to $150 per hour. As with traditional gas systems, plumbers have discovered that the pilot light is one of the most common causes of gas system failure. You may be able to identify the problem yourself, but if you are unsure or feel uncomfortable, it is best to consult with a specialist who has dealt with gas before attempting it. Replacement of a thermostat costs $50-$100 per hour of work. The thermostat that regulates the temperature in these systems is known as an Aquastat and costs between $70 and $150. These are really simple to get to and replace. Ensure you shut off your electrical system prior to starting. Low water level in the expansion tank: One of the most common problems encountered with boiler systems is that the water level in the expansion tank is too low. With a pressure of 12-15 psi, the ideal fill level is halfway up the tube. Filling the expansion tank is something that homeowners may do themselves. Leaking: up to $1,000 in repair costs. The majority of leaks should be dealt with by a professional. Their occurrence might be caused by a faulty pump or seal, silt accumulation in the system, defective valves, or weakened pipe connections.

Replacing Other Heating Elements

It is possible that replacing an existing system will be more difficult than just connecting the new system. Local building rules now require you to upgrade other components as well, such as the water heater mount, the venting system, the supply pipes, and the drain pan beneath the heater. In order to avoid unpleasant surprises during installation, request that your installer address these concerns prior to installation.

Pressure Relief Valve Price

It costs roughly $20 to replace a valve, and putting in a professional might boost your total cost to more over $200. This is not a prohibitively expensive investment in order to assure correct diagnosis and implementation. It is necessary to have a pressure release valve installed in case the pressure within the tank rises to a dangerous level. The presence of moisture seeping out of this valve at a “leaking” rate may indicate a number of possible concerns. It’s possible that silt has accumulated in the valve, that the pressure in your tank is too high, or that you require a whole new part.

You diagnose the problem yourself, be sure to switch off your unit, turn off the gas (if applicable), and allow the water to cool before inspecting the valve.

Anode Rod Price

Anode rods should be replaced every five years, according to plumbers. The rod itself costs between $20 and $50, and you may conduct this maintenance on your own if you follow the correct instructions and procedures. The anode rod prevents corrosion from occurring within your tank’s interior. It accomplishes this by attracting corrosion to itself. Depending on how badly your rod has rusted, your water will most likely be reddish-brown in color and may even have an odor and/or flavor to it. If you repair the anode rod before the corrosion has a chance to reach the interior of your tank, you will be able to extend the life of your water heater.

Dip Tube

Dip tubes are typically priced around $10. The cost of replacing them professionally is around $150.

These components are included in both electric and gas models, and they are responsible for transporting cold water from the top of your tank to the bottom. When your dip tube becomes dissolved or breaks off in the tank, your water will not heat up very much at all.

Cost to Flush or Clean the Tank

A plumber can recharge your tank for as little as $200. Regardless of whether you fix or replace your system, flushing the tank once a year to eliminate sediment will improve its performance and extend its lifespan. Your unit will run more efficiently, resulting in money savings for you. Neither natural gas nor electricity systems are exempt from this rule. The presence of noise, which is generated by sediment on the tank’s bottom, is a solid indicator that it is time to flush the tank. This silt might cause a heating element to fail, leaks to occur, or the unit to fail completely.

The cost of purchasing a new device will range from $750 to $1,300. A standard storage tank water heater has a lifespan of around 10-15 years; thus, if your unit is in that age range, it may be worth your while to invest in a new water heater rather than continuously repairing problems that emerge as a result of the aging process. However, if your water heater is only a few years old, it may be preferable to repair it rather than replace it. Tanks corrode as a result of the reaction between water minerals and steel over time.

It is possible that leaks from valves, pipelines, and vents are merely a matter of tightening and cleaning.

If you believe that hiring a professional plumber is the best option for you, read on.

Will a new system lower my bills?

A expert will almost certainly have excellent advice for improving the energy efficiency of your house. High-efficiency water heaters can heat your water more quickly and efficiently, allowing you to save money on your energy costs. Manufacturers are now injecting foam insulation between the tank and its exterior shell, resulting in greater heat retention. Tanks with new glass liners are less susceptible to corrosion. Installation of a new conventional storage unit may be necessary at your expense.

A tankless high-efficiency water heater is another choice to consider if you want an even more energy-efficient solution.

How Much Does It Cost to Repair a Water Heater?

In today’s houses, a water heater has proven to be an indispensable item. After all, most individuals don’t enjoy taking a cold bath. So if you’re having problems with your hot water, such as not having enough hot water or not having any hot water at all, your initial instinct may be to just replace it.

However, it is possible that this is not the best option. Before making the decision to replace your water heater, you may want to check to see whether it is possible to repair your current one.

Do I Need to Repair My Water Heater?

Despite the fact that many individuals are familiar with water heaters and water heater repair, many more are not. Nonetheless, it is something that almost everyone will have to deal with at some time in their lives because no water heating system is guaranteed to survive forever. The decision on whether or not to repair your water heater or replace it is entirely dependent on the nature of the problem that you are experiencing with it. Please read the following disclaimer: Easy AC suggests that you always consult with a qualified plumber when fixing your water heater and does not advocate that you repair your water heater yourself.

Troubleshooting Your Hot Water Tank

The very first thing you should look for is any signs of leakage. If there is water on the floor, avoid touching it or walking over it. Turn off all of the circuit breakers in your home and call a plumbing firm that provides emergency assistance in your region. The power circuit breakers or fuse box should be checked if there are no signs of leaking. If all of these are in working order, the next stop is the control panel. If there is water present within the panel, leave it open and contact a repair service as soon as you can.

You’ll be back in business as soon as the button is pressed and the power is restored.

It is rare that breaker or reset switches may be triggered by themselves; thus, you should consider it an early signal that you may want servicing soon.

Troubleshooting Your Water Heater

Gas water heaters are often more efficient and less expensive than electric water heaters; nonetheless, gas water heater problems can be difficult and even dangerous. If you are experiencing hot water problems, first check to see if the gas is turned on. If this is the case, the next item to look for is the pilot light. In order to check if the pilot is lighted on the water heater, turn the gas control knob to the “pilot” position and then remove the metal plate from the water heater. If the water heater is not turned on, you may turn it on yourself if you are familiar with the procedure, or you can call the gas company or a plumbing specialist for assistance with the process.

Should I Repair or Replace My Water Heater?

The conventional water heater will normally last between 10 and 20 years, depending on the degree of minerals in your water and how much water you consume. When determining whether to repair or replace your water heater, keep in mind that modern units are far more energy efficient. Consider how much money you will save on electricity bills when selecting whether to repair or replace your water heater. Repairing your water heater by a professional is always less expensive than replacing it, and it might save you money in the long term!

A water heater tank, for example, may build up silt and scale over time, resulting in overheating of the tank and corrosion of the anode rod sacrificially used to protect the tank.

To replace a dip tube, you must also remove a cold-water pipe, and replacing a heating component involves working with 220-volt electricity.

It is also recommended that any gas heater repair work be performed by a qualified professional in order to reduce the risk of gas leaks, fire, or harm to the homeowner.

The Costs of Repairing a Water Heating Unit

An investigation by found that the average cost to repair a water heater is $501, with the majority of homeowners spending between $203 and $800 for a single repair. As with any household appliance, certain parts will undoubtedly be more expensive to replace than others when it comes to repair. The following are the expenses associated with common boiler repairs: It costs between $175 and $485 to replace a faulty ignitor. The boiler ignitor is responsible for generating the first spark/heat that ignites the fuel in the boiler (oil, gas or propane).

  1. Consequently, if your ignitor fails, you will be unable to generate heat.
  2. It is possible for limescale to develop up in the walls of your boiler tank as a result of mineral deposits from hard water.
  3. It is also possible for sediments to collect at the bottom of the boiler container, reducing the amount of space available for water and interfering with the pressure regulators in the tank.
  4. The replacement of the expansion tank will cost between $230 and $650.
  5. It will cost between $435 and $1,800 to replace the circulator pump.
  6. It will not be possible to heat your home if your circulator is not functioning properly.
  7. If the pipes in your boiler unit burst or leak, it will lower the effectiveness of your system or cause it to cease operating completely.

Although this is true, there are frequently additional charges (apart from the water heater itself) that contribute to the overall repair fee.

Water heater repair costs can range from extremely expensive to quite affordable.

Many simple repairs may be performed by the homeowner if the homeowner knows what they’re doing, but there are some concerns that should be addressed by a certified professional plumber.

Depending on the problem, you may simply require a basic, affordable repair, such as replacing the anode rod if your water has an odor or replacing the pop off valve if the pop off valve is leaking.

The good news is that, because water heaters are made up of only a few pieces, there are only a few things that may go wrong with them when they fail.

In contrast, if the entire water heater needs to be replaced, the costs might become prohibitively expensive quickly. This is especially true when you consider the price of replacing or upgrading other elements such as supply pipes and the ventilation system.

How You Can Tell When A Water Heater Is Broken

Despite technological advancements, the water heater is still a pretty straightforward apparatus. The following are frequent problems with water heaters to be on the watch for: Water heaters tend to survive between 10 and 15 years on average. Some may live for a longer period of time, while others may not live for as long, but it is a realistic approximation to be aware of. Noise-If you notice noises coming from your water heater as it is attempting to heat water, it may be due to the accumulation of silt.

  • If the water flowing from the water heater is rusty, it might indicate that the water heater itself is rusting on the inside.
  • Having water leak around a water heater indicates that there is a leak in the tank itself, which should be investigated by a qualified specialist.
  • Make a conscious effort to increase the lifespan of your water heater.
  • The following are some excellent suggestions for keeping your water heater in good working order for a lengthy period of time:
  1. Make a point of flushing the water heater tank once a year. Every year, check the anode rod within the water heater tank and replace it if it has nearly completely deteriorated
  2. Otherwise, leave it alone. Keep an eye on the temperature and pressure relief valve on a frequent basis to make sure it’s still in good operating condition. Check for leaks in the pipes surrounding the water heater, which might cause it to fail. Adding an expansion tank to the water heater will alleviate pressure on the water heater if there is a valve that prevents water from backflowing to the water main. It is recommended that you install a water softener in areas where the water contains significant mineral content, often known as hard water, in order to prevent the negative impact that mineral deposits can have on the water heater tank.

Prices in different parts of the United States are different. Depending on where you reside, the cost of your hot water heater service might be either more or lower. Here are some examples of average expenses for various cities:

  • Among the most expensive cities to live in are Boston ($762), Los Angeles ($618), New York ($677), Chicago ($552), Houston ($622), Lincoln, NE ($663), Denver ($627), Tampa, FL ($539), and Nashville ($596).

How Much Does Hot Water Heater Repair Cost by Type?

Depending on the complexity of the problem, water heater repair costs might range from as little as $20 to several hundred dollars. Both electric and gas heaters are susceptible to the following problems.

Water Heater Leak Repair Cost

Leaks aren’t something you should ignore or try to deal with on your own; they require professional assistance. You’ll want to have a local plumber to take a look at things. It may be as easy as tightening and cleaning a leaking valve, or it could be much more complicated than that. Take off the bandage: if there’s water in your water heater panor anyplace below the unit, the most probable source of the problem is a leak in the tank.

Unfortunately, this typically signals corrosion or other damage that cannot be repaired. – You’ll need to replace your water heater, which will cost between $750 and $1,300. When it’s all said and done, treat yourself to a nice, soothing bath to reward yourself.

Pressure Relief Valve Price*

If the pressure within the tank builds up to an unsafe level, the pressure release valve securely relieves the pressure. Periodic gushing normally indicates that it is performing its function, but a persistent trickle of a “leaky” kind might indicate one of several things:

  • In the valve, there is an accumulation of silt
  • The pressure in your tank is excessive
  • You require a replacement pressure relief valve.

Replacing the pressure relief valve can cost up to $200 if a plumber is sent out, or it is a $20 item that just takes a few simple tools and can be done at yourself (see DIY repair cost section below). Always turn off the unit, turn off the gas, and allow the water to cool before performing any work on it.

Dip Tube Replacement*

The most common cause of your water not remaining extremely hot for an extended period of time is a cracked or rusted dip tube. Dip tubes are often available for purchase for under $10, with an average professional replacement cost of roughly $150. While the hot water is being used, this section of the heater transports new, cold replacement water down to the bottom of the tank, in both electric and gas heaters. It fails, the cold and hot water combine, resulting in a chilly and depressing shower before you have a chance to rinse the shampoo out.

Cleaning and Flushing the Tank

What exactly is that noise? If you hear something rattling about in the tank, it’s most likely silt settling in there. Not only is it inconvenient, but if left unattended, it might result in leaks, heating element failure, or the complete breakdown of the unit (oh no!). It’s a good idea to have a plumber flush it out as soon as possible for around $200. * Cost breakdowns for do-it-yourself projects may be found in the “Cost to Fix It Yourself” section below.

How Much Does Hot Water Heater Repair Cost by Style?

The presence of lukewarm water pouring out of your shower might indicate a variety of problems, including a thermocouple problem in a gas heater or a heater element failure in an electric heater, among others. Because each of them requires a separate set of parts and a different level of expertise, the cost varies depending on the style you have. Water heaters are divided into two major categories: gas and electric.

Gas Water Heater Repair Costs

The most common causes of gas water heater repair expenses are difficulties with the pilot light, thermostat problems, or a faulty thermocouple. Each one exhibits a unique set of symptoms, as well as a distinct set of water heater repair costs to accompany them.

Pilot Light

It is the most manageable problem to diagnose when your pilot light goes out since, well, the light isn’t on anymore. Finding the root of the problem may be as simple as identifying it, or it may indicate the presence of a more serious problem. First, try re-igniting the pilot light on the stove. Make certain that you are capable of doing so securely. If you don’t want to do this (and there’s no judgment), a service call might cost you anywhere from $45 to $150 per hour depending on the situation.


If you are experiencing problems with your gas heater’s thermostat, you will need to repair or replace the entire valve unit. A new one will set you back around $80.

Thermocouple Replacement Cost*

If your pilot light remains on but the burner does not ignite, it is likely that you have an issue with your thermocouple. The thermocouple detects the presence of a pilot light and utilizes this signal to activate the gas control valve, which then releases gas. The cost of hiring a professional to replace this item should be around $150 or less.

Electric Water Heater Repair Cost

There are a couple of issues that are special to electric water heaters that you should be aware of. These are typically caused by tripped breakers, broken heating elements, and malfunctioning thermostats.

Tripped Breakers

If it’s only a tripped breaker, that’s great! Simply reset it and begin thinking about the bubble bath you’ll be taking later in the day.

Heater Element Replacements*

There are two heating components in an electric water heater: one on the top and one on the bottom. The top controls the bottom, and if it fails, a very cold and very sad shower will be on the horizon in the not too distant future. Having this properly fixed will typically cost between $200 and $300 in most cases. * Cost breakdowns for do-it-yourself projects may be found in the “Cost to Fix It Yourself” section below.

Thermostat Replacement

Each heating element is equipped with its own thermostat, and if they fail to function, the elements will as well. The cost of hiring a professional to replace a thermostat is between $150 and $200. The part itself can cost up to $20 and can be readily replaced without causing any damage to the elements themselves. * Cost breakdowns for do-it-yourself projects may be found in the “Cost to Fix It Yourself” section below.

How Much Does It Cost to Fix a Water Heater Yourself?

If you’re a devoted do-it-yourselfer who is prepared to put in the time and effort to complete the research, you can save a lot of money on your hot water heater servicing cost. Make certain you follow all necessary safety precautions since hot water is extremely hot, and gas and electricity are not to be trifled with.

DIY Pressure Relief Valve Replacement Cost

A pressure relief valve replacement is a safe and very straightforward water heater repair that may be completed by the homeowner. The valve itself costs roughly $20, and you’ll need components worth between $10 and $13 if you don’t already have them in your toolbox to complete the project. The following are the tools and supplies you will require:

  • 5 dollars
  • Plumber’s tape ($4) or joint compound ($8)
  • And a wrench.

DIY Dip Tube Replacement Cost

When your water isn’t ice cold but obviously isn’t warm enough, a withered away or damaged dip tube is a typical problem. You can do it yourself with equipment that cost less than $10 and that you may already have on hand, plus a new dip tube that costs less than $10. Here’s everything you’ll need to get started:

  • Wrench costs $5
  • Screwdriver costs $3 (for prying out the old dip tube).

DIY Thermocouple Replacement Cost (Gas Heaters)

Are you unable to relight your burner or pilot light? It’s most likely due to a problem with the thermocouple, which causes the gas control valve to cease releasing gas when it should.

You can pick up the part for roughly $20, and the only other thing you’ll need is a little book knowledge to complete the project. Important reminder: Before you begin, remember to switch off your unit, disconnect your gas line, and allow the water to cool completely. Otherwise,ouch.

DIY Heater Element Replacement Cost (Electric Heaters)

Is the water coming out of your electric heater cold? This might indicate that your heating elements are malfunctioning. Shut down the electricity to the device before moving on to the testing portion of the process. You may purchase a continuity tester for roughly $10 at your local hardware shop, which will indicate whether or not the elements are functioning properly. If this is the case, you may have a defective thermostat in your possession. If testing reveals that they are truly not functioning properly, a tune-up kit, which costs around $30, can provide a much-needed boost to those heater components.

What Factors Influence Hot Water Heater Repair Cost?

It varies depending on the type of water heater you have, as well as the price of any replacement components you may require. The cost of hot water heater service is also a significant consideration. Will you be able to safely (and successfully) complete the repair on your own, or will you hire a professional to come out? All of these considerations are taken into account when estimating water heater repair costs.

Hot Water Heater Repair Cost Breakdown

It’s straightforward to figure out how much your hot water heater repair will cost: you’ll need components and you’ll need labor. Your final price will be determined by how expensive the part is and how much the professional charges. Many repairs are really simple to handle yourself if you don’t mind doing some research first, so this is one area where you can save a lot of money.


The cost of water heater repair varies depending on the item that is required. Many little components are $50 or less, yet a complete replacement might cost up to $1,300.


The majority of plumbers charge between $45 and $150 per hour. Notice that water heater repair charges typically include a little, cheap item as well as a disproportionately significant charge for labor. In the event that you are not the type to meddle with high-temperature appliances, or if you are not confident in your diagnostic abilities, the peace of mind is well worth the expense.


If you’re worried about your water heater, there are four big indicators that it’s likely to fail that you should look out for. The following are the most important death rattles to be on the lookout for:

  • The unit has been in operation for more than 10 years. The water coming out of your hot water faucets is rusty
  • You might hear pounding and rumbling noises as a result of excessive sediment accumulation. It appears that the leaks are originating from the tank itself (and not from valves or connectors)

Take a deep breath and know that you can do it. If you see any of these indicators, you should start thinking about a replacement before the ice-cold shower compels you to do something.

How can I maximize the lifespan of my water heater?

The importance of learning how to examine and repair your water heater on a regular basis should not be underestimated. Back to the tank flushing that was stated earlier: be sure you perform it once a year to prevent any unpleasant sediment from accumulating and wrecking havoc on your water heater. When done by a skilled plumber, this might cost as much as $200 or more. Every five years, you should also replace your anode rod with a new one.

This rod is responsible for preventing your tank from corroding and dying a premature death. It is made of copper. A replacement rod costs between $20 and $50, and you may perform this maintenance on your own (with the proper instruction and precautions, of course).

2022 Water Heater Repair Costs

Here are some estimates for water heater repair costs for some of the most frequent water heater problems:

  • A thermocouple that has been cleaned and repaired costs $395
  • A thermostat and/or heating element that has been replaced costs $150–200
  • Leaks: Unless the equipment is still under warranty, it is often not cost-effective to fix them.

An inability of a hot water heater to perform its function is one of the most prevalent plumbing-related problems in a house or an apartment building. It’s possible that a pilot light has gone out, in which case homeowners may generally relight the pilot light themselves by following the manufacturer’s instructions written on the unit’s outside. [Note: if you smell gas, do not attempt to fire the pilot on your water heater.] Instead, call your local gas provider to determine the source of the problem and resolve it.) For those who have frequent pilot light failures, it may be required to have a professional examine the thermocouple, which is a safety mechanism that detects when the pilot light is burning and notifies the gas valve to close when the pilot light is not burning anymore.

  • Because it is constantly in contact with the flame of the pilot light, the thermocouple might get dusty and cease to function over time.
  • In the Jacksonville, Florida, region, Kenny Lowenthal, owner of the company Major Appliance Repair, says the two most frequent water heater faults he finds involve the replacement of one (or occasionally both) a thermostat or a heating element.
  • When a thermostat fails, Lowenthal costs $185 to replace it and $200 to repair both the thermostat and the heating element.
  • Zip code must be entered correctly.

Water Heater Repair Service Costs Guide

Posted on the 25th of August, 2020, by carrolladmin The notion of having to repair a hot water heater might be a little intimidating. How much will it set you back? How long do you think it will take? Although it may be tempting to disregard small issues, it is really more cost-effective to address them as soon as feasible. The longer an issue is left unattended, the more expensive it is likely to become when the system deteriorates or fails completely. So, what will the cost of water heater repair be?

Common Water Heater Repair Issues

The nature of the problem is perhaps the most important aspect in deciding how much it will cost to repair it. Some water heater problems are more expensive to repair than others. Listed below are a few of the most typical problems that homeowners have with their water heaters:

Dip Tube – $10 to $150

The dip tube is responsible for transporting cold water to the tank’s bottom for heating.

Unless the dip tube is properly maintained, it will not heat the water as efficiently as it could otherwise. It costs roughly $10 on average to get a new dip tube, and it can cost as much as $150 to have it properly fixed.

Pressure Relief Valve – $20 to $200

The pressure relief valve ensures that the pressure in your water tank remains within acceptable limits. If the pressure rises up to a dangerous level, this valve will open to alleviate part of the excess pressure. The presence of regular leakage may indicate that the tank’s pressure is too high, or it may indicate that the valve is malfunctioning or obstructed in some way. The cost of a new pressure relief valve is around $20, and the cost of repairs might reach $200.

Anode Rod – $20 to $50

The anode rod in your water tank serves the purpose of protecting the tank against corrosion. It accomplishes this by first corroding the anode rod; as long as the anode rod is corroding, your water tank and heating element will not be affected. Once the rod has rusted out, additional elements of your water heater will begin to deteriorate as a result of the corrosion. Once every five years or so, it’s advised that you repair your anode rod, which is a process that normally costs between $20 and $50 to complete.

Common Electric Water Heater Repair Issues

Furthermore, in addition to these typical drawbacks, electric heaters will have their own set of issues that distinguish them from other types of systems. These may include the following:

Electric Thermostat – $150 to $200

The thermostat in your water heater is in charge of regulating the temperature. If it determines that greater heat is required, it will activate the heating components. Once the water has reached the desired temperature, the elements are switched off. If you discover that you are not getting enough warm water, it is possible that you have a thermostat problem. The individual part normally costs around $20, but it is suggested that you have expert repairs done, which might cost up to $200 in some cases.

Heating Element – $200 to $300

Electric water heaters heat the water by heating it with a conductive metal element. As a result, if the element becomes corroded or ceases to work, you will not receive hot water. It might cost up to $300 to have a heating element professionally repaired. More information about water heater repairs may be found here.

Common Gas Water Heater Repair Issues

Because of the variations between gas and electric heaters, gas units will have a separate set of concerns that might occur in the future. The following are some of these issues:

Thermocouple – $20 to $150

When the pilot light in your gas water heater goes out, the most common cause is a faulty thermocouple, which may be replaced. An equipment that detects whether or not the pilot light is illuminated and activates the gas control valve is known as a thermocouple. When it comes to having it properly repaired, it normally costs approximately $150, however a new thermocouple itself only costs about $20 on average.

Gas Control Valve – $300 to $500

Another problem that might arise is a malfunctioning gas control valve. If neither the thermocouple nor the pilot light are failing, this is typically the underlying reason, and having it properly fixed might cost you up to $500 in labor and materials.

It is critical to have this updated, regardless of how expensive it may be to do so since, without it, the unit would not be safe to function because the gas flow will not be correctly controlled.

Common Tankless Water Heater Repair Issues

Tankless water heaters are a relatively new technology that can help you save money on your water heating bills by eliminating the need for a tank. Because they operate in a manner that differs from that of traditional water heaters, they will present their own set of problems. Professional repairs are frequently necessary, and they can cost anything from $150 to more than $800, while the average cost is usually around $600. Tankless water heaters must be flushed on a regular basis to prevent mineral and sediment buildup inside the device.

A typical flushing and cleaning job might cost up to $200 on average.

Other Costs to Consider With Water Heater Repair

Of course, there are a variety of additional elements that might influence the cost of repairs. The majority of plumbers and technicians will bill their clients on an hourly basis, with rates often ranging from $50 to $150 per hour for their services. Additionally, if your system is still under warranty, your hot water heater repair expenses will most likely be far lower than if your unit is more than a decade old.

Hot Water Heater Installation Prices

Replace a water heater entails a number of elements that all influence the ultimate project cost, starting with the size and kind of unit that is used and progressing from there.

Tank vs. Tankless

For more than a century, tank-type water heaters have been the industry standard for heating water. They keep the hot water in tanks ranging from 30 to 80 gallons. In the United States, this form of water heater accounts for more than 85 percent of all domestic water heaters. A tank-style hot water heater installation costs on average between $ 650 and $2,100, which includes the cost of the new water heater, supplies, and installation labor. They can be powered by electricity, gas, propane, or fuel oil, and they have a lifespan of 10 to 12 years.

The water is heated as it passes through the waterline, rather than being stored and kept hot by using energy to maintain the temperature of the water.

They can be fueled by gas or electricity and have a lifespan of more than 20 years in many cases.

Tank Size or Tankless Water Heating Capacity

The size of the water heater has an impact on the cost as well. Typical tank-style heaters have storage capacities ranging from 20 to more than 80 gallons, with most households opting for a 40 or 50-gallon capacity. The size of a tankless water heater is measured in gallons per minute, with a flow rate ranging between two and six gallons per minute (gpm). For the majority of households, a greater flow rate of four to six gpm is advised. Make certain that the replacement unit you purchase will provide adequate hot water for the amount of people who will be living in the house.

Gas vs. Electric

Depending on the model, water heaters are powered by gas (natural gas or propane) or electricity. Heat is given either by a gas flame or by an electric coil, depending on the application. Compared to gas water heaters, electric water heaters cost between $100 and $200 less. Nonetheless, because of the greater cost of electricity and the lower cost of natural gas and propane in many parts of the nation, gas water heaters are frequently more cheap over the course of the unit’s useful life. Electric water heaters are still an excellent solution for tiny or limited spaces since they do not require any venting to function properly.

Direct Vent vs. Power Vent

Gas water heaters create exhaust that must be vented either directly overhead through a vent flue or through a power vent blower to provide proper ventilation. Unlike indirect vent water heaters, direct vent water heaters exhaust through a flue pipe located above the device. You should budget an additional $500 to $1,000 to build the vent pipe if you are replacing an electric water heater with a direct vent natural gas water heater. Power vent water heaters employ a fan to blast exhaust out through vent pipes, which is a more environmentally friendly option.

When compared to a direct vent system, this method provides greater flexibility in terms of where the unit may be installed while also being more energy efficient.

Installing power venting devices is around $300 to $600 more expensive than installing direct venting systems, with additional costs for cabling and electrical work ranging from an additional $300 to $500.

Labor Cost to Install a Hot Water Heater

In addition to the cost of the device, the labor fee accounts for a significant amount of the total installation cost. Prices for labor might range from $150 to $1,000 or even more per hour. They vary depending on the hourly rate of the installer, the size and kind of water heater being installed, and the location of the installation.

Cost Per Hour

The majority of the work involved in installing a gas or electric water heater may be completed by a plumber. Their labor charges range from $45 and $150 per hour depending on the position. An electrician will be required if the task involves extensive electrical work, such as the installation of a new circuit or the conversion from gas to electricity. The cost of an electrician’s services will range from $50 to $100 per hour.

Average Hours Per Water Heater Type

Replacement of tank-type water heaters, whether gas or electric, takes around three hours in most cases. The installation of a tankless water heater will take between eight and ten hours. If you are switching from a gas to an electric water heater, or vice versa, or if you are moving the water heater to a new location in the house, this can significantly increase the length of the job and may even necessitate the hiring of additional types of labor, such as carpenters or drywall installers, to complete the project.

Additional Water Heater Replacement Cost Factors

In addition to the cost of the appliance and the work of the installation, there may be other fees associated with replacing a water heater. Included in this are permit fees, the installation of an expansion tank, the removal and disposal of the old water heater, the installation of water or gas lines, electrical or carpentry work, and the price of materials and labor.


A plumbing permit is usually required when replacing a hot water heater in most areas. The permit is necessary so that an inspection may be carried out to check that the work was completed in accordance with current safety and quality standards and regulations. Depending on the specifics of the project, many permissions may be necessary, with total permit charges ranging between $50 and $500, and perhaps as high as $1,500.

Expansion Tank

The use of an expansion tank is a safety feature that protects pipes from collapsing in the event that the water heater’s tank malfunctions. However, while many older homes do not include one, it is sometimes required by local building requirements that one be added when a water heater is replaced. The cost of installing a new expansion tank ranges from $40 to $350.

Tank Removal

The old tank must be removed in order for the new one to be installed. The cost of removing the old tank will range from $100 to $500, depending on the contractor’s rate, the size of the tank, and the ease with which it can be reached. Expect to pay more if the object is large and difficult to remove.

Relocating the Unit or Fuel Conversion

Moving a water heater to a different place in the house, switching from one fuel type to another, or even upgrading to a larger tank can all increase the cost of installation dramatically. Water line rerouting ($350 to $1,700), framing a wall ($200-$400), installing drywall ($800-$2,500), adding a gas line ($250 to $800), or extending electrical wiring ($500 to $1,500) are all possible requirements for your project.

You should consult with your installer if you are considering anything other than a direct replacement.


In addition to incidental materials such as solder and pipe thread compound, replacing a water heater may necessitate the purchase of other things such as venting pipes, connectors, water or gas piping, pipe fittings, and other related products. Depending on the specifics of the project, these elements might represent anything from a little to a major increase in expenses. Replacing a water heater is not a do-it-yourself activity, and it is slightly more expensive than replacing other equipment.

There are numerous variables that influence the time it takes to complete the installation, including the cost of materials and labor, the availability of permits, the labor of a licensed plumber, the removal of an old unit, the ease of access, and other factors that may prolong the time it takes to complete the job.

Frequently Asked Questions (FAQs)

Traditional tank-style water heaters have a lifetime of eight to thirteen years. They are not energy efficient. Tankless water heaters have a lifespan of 20 years or longer.

Can I install a water heater myself?

It is conceivable for an experienced, highly-skilled DIYer to obtain the necessary licenses from the local authorities and install a water heater in their own house, but making mistakes may be both costly and potentially deadly. The expense of cleanup and repairs, if anything goes wrong, can rapidly become more expensive than the cost of hiring a professional in the first place.

Should I buy a water heater from a plumber?

It’s common to be offered a labor warranty when working with an experienced plumber. An additional guarantee offered by the plumber, in addition to any parts or equipment warranty provided by the appliance’s manufacturer, may cover the cost of any repairs necessary as a result of incorrect installation work.

What are the signs your hot water heater is going out?

The majority of people will wait until their water heater has fully failed before they replace it. Avoiding this tension by arranging an inspection or replacement when any of these symptoms appear can help to alleviate it.

  • The water heater has reached or is nearing the end of its expected service life
  • The hot water is rapidly depleted. The temperature of your shower is uneven
  • It appears that water is seeping from the tank. Water that is discolored comes from the faucets. The pressure of the water has reduced
  • The water does not get heated
  • Instead, it remains cool. Noises emanating from the heater, such as loud cracks or pops, for example

Why do water heaters fail?

Premature failure of a water heater can occur for a variety of causes that can be avoided. Keep an eye out for these concerns and be prepared to take action if they develop.

  • Internal corrosion as a result of a worn-out anode rod Check the anode rod once a year and replace it if it appears to be worn
  • Because of the high mineral concentration of the water, sediment accumulates inside the tank. Annual tank cleaning is recommended to prevent sediment accumulation. Excessive water pressure can cause damage to the water heater as well as other components of the water system. If the pressure of the water entering the home is more than 80 psi, the pressure release valve should be adjusted or replaced. A water heater that is not properly sized will be overworked, leading components to wear out sooner than they should. Install a new hot water heater that is appropriate for the number of people living in the house
