Recognize When Your Hot Water Heater Smells Like Burning!
- A burning scent in the house is never a good indication, since it indicates a potential fire hazard in the vicinity.
- It is therefore necessary to explore if you are asking yourself, ″Why does my hot water heater smell like burning plastic?″ In the majority of situations, it is a symptom of an overheated or malfunctioning component.
- It is important to never overlook the scent of a new hot water heater that is burning.
- Hot water heaters, whether old or new, are susceptible to developing a burning smell at any time.
- There are a variety of reasons why your water heater smells like it’s burning, some of which are not particularly dangerous.
- Nonetheless, it is important to understand where the scent came from and what can be done to eliminate it.
Here are some reasons why your hot water heater smells like burning:
Keep in mind that it is usually advisable to cut off the electricity at the breaker before attempting to locate the cause of the burning smell throughout the home. The rubber or plastic is on fire.
- Alternatively, if your water heater smells like plastic or rubber, it might be due to overheating of the electrical contacts on the thermostat.
- The connections for the water heater are positioned outside the unit.
- Another component that might be overheating and burning is the insulative coating that is applied to the wires themselves.
- This is most likely to occur if the insulation is outdated or has not been adequately packed.
- A consequence of this is that the wires will come into direct contact with the heating element, causing it to overheat.
- The most effective remedy to the problem is to replace the insulation or to move the plastic piece away from the heating source as described above.
If you are unsure of how to proceed, seek the assistance of a professional to resolve the issue for you.An electrical burn is now taking place.
- In general, an electrical burn is difficult to detect since it might be odorless in some cases.
- If, on the other hand, an electric heater emits a burning odor, the odor is a rather acrid scent of plastic being consumed.
- When this occurs, it typically indicates that something electrical is overloaded or that an electrical short has occurred in an outlet or wiring system.
- It might be caused by an overheated electrical contact or a failure of the fire rod.
- This odor should be checked for arcing in the wiring of your water heater if it is present near your water heater.
- The presence of an overheated electrical contact indicates that heat is being created at the connection points in question.
Excess current will produce a short if the fire rod is in the process of dropping.As a result, the wiring and thermostat become hot, and an electrical burning smell is released into the air.Whatever the situation, if you sense an electrical burning smell, you should contact a skilled specialist immediately.In any case, a plumber will either fix the wiring or advise you on whether it is necessary to replace the water heater altogether.
There is a fire in the dust or dirt.
- It is normal for your water heater to acquire dust and dirt, just like any other appliance in your home.
- Consequently, you shouldn’t be astonished if you haven’t cleaned your heater in a long time and the scent of burning dust arises overnight.
- When dust and debris build up on the heating element of a water heater, they will ultimately catch fire and burn.
- While this does not necessarily pose a fire threat, the odor is not very pleasant.
- As a result, removing the cleaning supplies is the most effective method of getting rid of the odor.
- To avoid the smell in the future, be sure to wash down your water heater from time to time to remove dust and debris that has accumulated.
Problems with the air pressure
- If your water smells like burnt plastic, it’s possible that you have an issue with air pressure within your water heater.
- When a water heater is in use, it creates vapors that are expelled through an exhaust pipe into the atmosphere.
- It is possible that if the air pressure is not maximized, the vapors will linger inside the tank, which will result in a house that smells like burned plastic.
- It is necessary to hire a plumber in such a situation in order to correct the air pressure in the water heater.
- Other odors that are connected with a hot water heater include: The water heater has a gas-like odor about it.
- When a gas-like stench is detected in your house, it is important to take action immediately.
- It is critical to determine where the odor is originating from as soon as it appears.
- Any equipment that consumes gas has the potential to be the source.
- If you have a gas water heater, for example, look around the area where the water heater is located.

It is therefore imperative that action be done as soon as your water heater begins to leak natural gas.The water heater has a sulfurous odor about it (rotten eggs-smell)
- The simplest way to describe the smell of sulfur is to compare it to that of rotting eggs.
- This type of odor is frequent in water heaters, and it may be quite unpleasant.
- While it is not normal for a new water heater to smell like burning, it is possible that your new water heater will smell like sulfur when first turned on.
- When the scent occurs, it might be caused by one of two things.
- It might be caused by a high concentration of sulfur-reducing bacteria in your water supply or by a corroded sacrificial anode rod in your system.
- A flush and disinfection of the water heater will be required if bacteria is the source of the problem.
If an old anode rod is the only source of the problem, the rod will need to be replaced.In any case, placing a zinc anode rod would be the most effective method of preventing the stench from recurring.

Why Is There Burning Smell from My Heater – Elite Heating & Air Conditioning
- If you notice that the smell of burning emanating from your water heater one day, you’d be excused for thinking that it might be time to contact your local plumbing services.
- Prior to doing so, you may be shocked to hear that you can resolve some of the issues that are contributing to the odours yourself, if you look into it.
- First and first, it’s critical to determine the source of the odor and then determine if the problem requires urgent attention or whether it will resolve itself on its own after some time.
- What you do next will be determined by the severity of the problem and what is causing the heater to emit an unpleasant burning smell.
- Throughout this post, we’ll look at some of the most typical difficulties that might result in a burning smell coming from the heater, and we’ll discuss what you can do to resolve the issue yourself.
- Any difficulties will require the assistance of heater repair services, but it’s always worth checking to see if some do-it-yourself work will solve the problem first before calling in the professionals.
- The most typical reason of a burning smell coming from the heater is burning dust, which is almost always present.
- This is most common when the heater has not been utilized for an extended period of time.
- During periods of inactivity of several weeks or months, dust and grime accumulate on the heat exchanger, within the furnace, and on the heating components.
- When the colder months approach and you switch on your heating system for the first time, the heating components ignite and burn away all of the dust and filth that has accumulated over the course of the summer and fall.
- Fortunately, the burning smell should only last a couple of hours at the most, rather than for several days or weeks.
- Once all of the dust and debris has been burnt away, the odor should ultimately subside and the environment should become more normal.
You don’t need to do anything other than open a window and allow the air to circulate through your home to get rid of the stink as fast as possible.
- If you notice the smell of burning plastic emanating from your heater, this is absolutely something you should look into right away.
- When plastic burns, it may release poisonous fumes that are harmful to breath, making it extremely dangerous.
- What’s more, your HVAC system might be circulating this toxic air throughout your home, potentially causing injury to anybody who is present in the structure.
- For prevention, turn off the heater as soon as you notice the smell and then try to determine where the scent is from from.
- There’s a good likelihood that something has been caught in your heater and is melting near the furnace or someplace in the ductwork if it smells like burning plastic.
- A variety of items, ranging from children’s toys to plastic bottles and everything in between, have been reported as being lodged in there by various individuals.
Occasionally, the plastic smell can be traced back to some of the furnace parts that have come loose or been worn out.If this is the case, they must be changed before the heater may be restarted.In order to resolve this, you should first inspect the heater to see if anything has been trapped in or around it, and then inspect the ducting to see if any plastic things have made their way up there from the ground.If the odor persists, you will need to contact your local air conditioning repair service to come and inspect the unit before you can turn it back on.
- Another typical reason of burning odors emanating from the water heater is electrical problems, which should be examined as soon as possible. It is common for an electrical scent to indicate the presence of a significant electrical issue someplace that has to be addressed immediately. Electrical problems are one of the most prevalent causes of house fires in the United States, so if you suspect that there is a problem, you should turn off the unit immediately and keep it turned off until you have determined the source of the foul odor. The majority of water heaters should be equipped with a failsafe that activates when the heater overheats or has a significant failure. If you detect electrical burning in the heater, this indicates that the safety device has failed and that the heater will most likely continue to cause harm until it is turned off. Here are a few examples of possible perpetrators: A blower motor that is overheated
- a cracked heater exchange
- faulty or damaged wiring
- and so on.
Any one of these factors has the potential to create a very dangerous fire hazard. If you are unable to identify and correct the problem on your own, you must contact heater repair services immediately to rectify the situation.
Oily or smoky smells
- Water heaters come in a variety of shapes and sizes, and one of the options available for your residence is an oil furnace.
- An oil reserve tank is used in conjunction with these versions to inject oil into the water heater’s combustion chamber.
- Once the fuel is ignited, it heats up along a vertical coil within the water tank, which in turn heats the water within the tank’s holding tank.
- While these furnaces are recognized for their energy efficiency, they are also known to emit greasy and smoky odors throughout the home from time to time, which can be unpleasant.
- In most cases, this is totally normal, especially if it is the first time you have used the heater after a lengthy period of inactivity.
- However, if your heater has been running for more than a few hours, you should not be able to detect any oil smell.
A strong stench in your house when you’re using an oil furnace might be the result of an oil spill or leak in the heater, or it could indicate that it’s time to change the oil.If you don’t change the oil in your heater on a regular basis, it will cause problems and cause your heater to malfunction.Furthermore, oil-water heaters emit exhaust gases, which must be vented to the outside of the building in order to be effective.Occasionally, there may be a problem with the vent, resulting in some of the gases being released throughout your home, generating an unpleasant odor and maybe causing injury.
Check for leaks and replace the oil if the oily odor remains for more than a few hours after you’ve tried everything else.If this does not fix the problem, it is necessary to contact heater repair services.
Musty or moldy smells
- A typical issue individuals have while using their heater in the winter is the smell of musty or moldy materials coming from the unit.
- Once again, this is rather normal when the heating system has been left inactive for several months and should subside in due course, as it usually does.
- This, on the other hand, might indicate that your HVAC system is in need of repair.
- The majority of the time, offensive scents like these are caused by clogged and unclean air filters that need to be replaced.
- At the absolute least, filters should be replaced once every two to three months, but changing them once per month is preferable if you use your system frequently, have pets, or smoke indoors.
- The filter is in charge of eliminating dust, grime, germs, and allergies from the air that passes through it.
Once the filter becomes clogged, it is unable to perform its function and, more often than not, resulting in the circulation of musty or moldy air throughout the home.As you could assume, this is not the best air quality for breathing, therefore you should turn off the system and replace the filters as soon as possible.
Rotten egg or a sulfur smell
- Finally, the smell of rotten eggs or sulfur is typically indicative of a more serious problem in the home, such as a gas leak.
- This is not anything to play with, so if you notice a strange smell emanating from your heater, switch it off immediately (along with the rest of the equipment in your home) and call the heating repair services.
- If you are indoors, you should get outside and avoid breathing the air since it might be poisonous and hazardous to your lungs.
- To discover a remedy to the burning smell coming from your heater, the most effective method is to follow your nose and pinpoint the cause of the problem.
- When we switch on our heater for the first time in several months, we may notice a foul stench, which should subside after a few hours.
- In some cases, a foul odor may persist for several days.
- But if the stench remains and you are unable to resolve the problem with the procedures outlined above, you should contact your heater repair agency to have a professional inspect the situation further.

Why Does My Water Heater Smell Like It’s Burning?
The following are some of the most typical reasons why a heater smells like it’s on fire, according to experts.
1. Gas Leak
Gas, on the other hand, does not smell like anything. In order for consumers to detect if there is a gas leak, producers add fake scents to the products they produce. If you know how to turn off the gas, do it immediately, then evacuate your home as securely as possible and notify the police.
2. Corroded Anode Rod
- Metals corrode when exposed to water.
- Metals are used in the construction of water heaters.
- In order to resolve this problem, manufacturers incorporate a magnesium rod into every heater they produce.
- This rod corrodes before the water heater itself, releasing electrons into the tank and preventing the water heater itself from corroding further.
- That being said, nothing lasts forever, and when it comes time to replace an anode rod, your home will smell like rotten eggs for a few days thereafter.
- To discover how to change it, cut off your water supply and watch this instructional video on the subject.
3. Air Pressure Problems
Is the stench of burning plastic emanating from your water heater? The exhaust pipes of a water heater are responsible for releasing the vapors produced by the heater. It is necessary to optimize the air pressure in order for this to function efficiently. If you don’t do this, some of the fumes will linger in the heater and your home may begin to smell like burnt plastic.
4. Wiring Issues
If your home smells like burning wires, it’s likely that you have burning wires. Call an electrician to come out and turn off the circuit breakers that give electricity to your water heater. The only method to address this situation is to replace the faulty wires.
It’s possible that dust will collect in your heater’s air ducts if it hasn’t been used in a while. As soon as you switch on your water heater or your air conditioner, your house will begin to smell like burning dust. This is a small problem that will correct itself as long as you continue to use the heater.

Why Does My Water Heater Smell Like Burning Plastic?
- The scent of plastic being burned is not pleasant.
- In the event that you have this problem in your house and have narrowed it down to the water heater, you may be wondering why your water heater is emitting this odor.
- The presence of burning odors should not be ignored, even though it is unlikely that your water heater is on fire.
- It is still a matter of public safety.
- Before calling a plumber, check for the following possible reasons of a burning plastic odor coming from the water heater before calling him.
1. Plastic Parts
Within the water heater, there are certain plastic components can be found. Depending on how hot the contacts are getting, they might create enough heat to melt or burn the plastic components within the water heater. If you have any reason to believe this is the case, you should switch off the water heater and call a professional to come and fix the problem.
2. Hidden Plastic
- This probable source of the horrendous burning sound is far easier for homeowners to identify and deal with on their own than it is for professionals.
- Your water heater creates a great deal of heat and feels pretty warm to the touch when you touch it.
- If a plastic object is placed too close to the heater, it may melt or catch fire.
- Consider looking around the heater to check if anything, particularly children’s or pet’s toys, has been left near to it accidently by accident.
3. Wire Insulation
At the very least, wire insulation contains a little amount of plastic. It is possible that some electrical faults, wiring malfunctions, and other issues will cause the wire insulation to melt or burn, resulting in the odor. If this is the case, you should cut off the water heater’s electricity and call a professional to come and fix it.
4. Burning Dust
- If it smells like plastic, are you certain it is plastic?
- If there is a more general burning scent, it is possible that dust is burning instead of actual fuel.
- A buildup of dust within or outside of the water heater, particularly if the heater has been switched off for a short period of time, may eventually result in a burning smell.
- During the normal maintenance of the water heater, your plumber should clean the water heater to avoid this problem from arising again.
Do you believe you can detect the unique charred odor of gunpowder in the air? That the fan motor or circuit board has fried or suffered significant damage might be the cause of the problem. If you detect the odor of gunpowder, turn off the water heater and contact a specialist as soon as possible.
Are you unsure of what else may be causing the issue?The majority of burning odors are caused by a water heater overheating for one reason or another and then harming a component within the heater, according to the manufacturer.Overheating is a safety hazard, and it may also cause damage to the internal components of your water heating system.If the overheating is allowed to continue, it is possible that a component or the entire system may need to be replaced.It is still recommended that you contact a professional even if you believe that dust is the source of the burning scent.Burning odors might be a sign of more serious conditions.
Heater Smells Like It’s Burning? Here’s What to Do
It is understandable that many people are concerned when their heater emits an odor that appears to be burning.After all, the majority of burning scents in the house are generally a warning indication of impending danger.Do you think this is always the case in the context of central heating, though?When it comes to indoor airflow, the reasons for a burning smell might range from completely innocuous to potentially dangerous.Consider some of the reasons why your house heater is releasing a burning smell, as well as what you should do if you find yourself in one of these situations:
A large number of people of southern states in the United States do not use their house furnaces on a regular basis.The furnace and air ducts, whether they are in the basement or the attic, can gather dust over time.The same may be said for persons who live in places where the temperature changes from season to season and who may not require central heating for several months at a time during the winter.Depending on how much time has elapsed between now and the last time you turned on your central heating, the dust in these locations may be burned away as a result of the heat.In the vast majority of cases, this is not a reason for alarm or worry.Hopefully, the burning smell from the heater will subside within a short period of time.
If your heater emits a burning smell after being turned off for an extended period of time, wait around five minutes to see if the scent fades.However, if the problem persists after that, it might suggest a more serious problem requiring the services of an HVAC or furnace repair professional.
Trapped Debris in Central Heat System
Occasionally, little plastic or rubber things will fall into vents or further into the air ducts.This is normal.Whether it’s a lost child’s toy, a component of the HVAC system, or another object, a burning odor may result as a result of this.When you first notice a burning smell coming from your heater, you should try to locate the particular vent that is causing the odor to be released.If the noise is just coming from one area of the house and not from the entire structure, it is possible that something is blocking the vent.Examine the interior of the vent to see if there is any trash or foreign items.
Remove the vent cover if it is safe to do so, remove the object from the vent cover, and replace the vent cover.If the debris looks to be a part of the furnace or HVAC system, contact a furnace repair professional in your area to determine whether the debris should be replaced.
Filter Replacement Needed
When an air filter becomes clogged, the furnace may overcompensate in trying to push more air through the system. Verify that your vent filters are not clogged with dust and/or debris by inspecting them. If you do not have a replacement filter at home, you should be able to locate one at your local hardware shop that will work with most systems.
Furnace Repair Needed
A burning odor might also be caused by a malfunctioning furnace or structural damage to the unit itself.Depending on the severity of the problem, it might potentially turn into a fire danger that necessitates prompt action on your part.If you sense a burning smell in your home but are unable to identify the cause, it is possible that your furnace needs to be repaired.You should, in this instance, contact a qualified HVAC professional as soon as you can and set an appointment for them to come out and inspect your furnace.
Burning Smells Non-Central Heat Sources
Space heaters are plug-in heaters that are portable and can create fires if they are used in close proximity to other heat sources, clothes, or thick carpeting.It is preferable to use a space heater on top of a hard surface and away from any fabric things while utilizing a space heater.It is possible that a space heater is emitting a burning odor because of a malfunction, which might result in the heater catching fire.If the system is not sparking or displaying any other obvious indicators of danger, disconnect the heater and make arrangements to get a new one.Immediately switch off the electricity in that section of the house if it is generating sparks or causing other apparent electrical discharge before removing the plug from the outlet.Do not touch the plug unless you are wearing some sort of insulating hand covering, such as rubber gloves.
The use of baseboard heaters as an alternative to a furnace is becoming increasingly common in smaller living areas such as flats, condos, and small houses.Despite the fact that they differ from a central heating system in the manner in which they give heat to the living area, a burning smell from a baseboard arrangement may have some similarities to a central heating system in its reasons.It is possible that a baseboard heater is emitting a burning smell as a consequence of dust and debris, or that it is experiencing an electrical problem.If, as with a central system, the odor does not disappear after a few minutes and there is no apparent material obstructing the airflow, you should contact an HVAC specialist immediately to conduct a more thorough check.
Radiator heat is deemed an outmoded option when compared to baseboards and central heating systems, according to modern construction regulations.Radiators, on the other hand, are still used in many older homes.If you notice a burning smell coming from your radiators, it might be due to dust or debris in the system, much like with your baseboards and central heating.When it comes to radiators, however, this might also signal the existence of mold in the system or the presence of a corrosive material known as hydrogen sulfide in the system.Hydrogen sulfide has the potential to corrode metals and generate a stench that is similar to that of eggs.If you notice this odor, you should contact an HVAC specialist as soon as possible to avoid further damage to your HVAC system.
