How High Should A Water Heater Be Off The Floor?

3 Reasons Why You Need To Use A Hot Water Heater Stands

  • You have most likely just purchased a new water heater, and the first thing you notice about it is that it does not have any legs to provide support and keep it up off the ground.
  • The million-dollar question is now in your mind: do I really need to utilize hot water heater supports to raise my water heater?
  • The primary reason you should have your water heater installed on a hot water heater stand is to prevent fires from occurring.
  • Fuel or any other combustible fluid that has leaked into the garage floor can be prevented from igniting by raising your water heater off the floor.
  1. You could believe that the new ″FVIR″ versions of water heaters are resistant to flammable vapor ignitions and can be installed everywhere, but believe me when I say that most authorities will not be pleased with this.
  2. Each and every country on the planet has its own set of plumbing laws and standards, which every water heater owner must adhere to in order to safeguard the safety of their family and their own property.
  3. This is why most communities have safety standards in place that you may not understand.

  • Water heater stands must be able to elevate your water heater at least 18 inches from the ground.
  • You have undoubtedly read on some sites that you do not need to elevate your water heater as long as it is not located within your garage or house.
  • This is probably true.
  • My recommendation is that because it is still a water heater unit, it should be elevated 18 inches from the ground to prevent any problems with the government.
  • Any water heater having an ignition source must be installed so that the ignition source is not less than 18 inches above the floor while the water heater is not in use.
  • Purchase a water heater stand and you can expect your water heater to survive for several generations.

How High Off the Ground Should a Water Heater Be?

  • Hot water heaters offer warm water for use in laundry rooms, bathrooms, kitchens, and other areas of a home or business, among other things.
  • They are often found in basements, attics, garages, crawlspaces, or closets that have been specifically constructed to accommodate them.
  • These devices heat and circulate water, which is then delivered to its final destination by pipes.
  • There are many different types of hot water heaters available, however some of them should not be put directly on the floor.


According on the type of water heater you have, you will need to elevate it off the ground by a specific amount. While electric and heat pump hot water heaters are permitted to be installed on concrete floors, gas water heaters must be elevated by at least 18 inches from the floor.

Types of Hot Water Heaters

The specialists at have compiled a list and description of the many types of hot water heaters.The first type is the typical storage model, which is comprised of a tank for storing materials.Heat pump water heaters vary from other types of water heaters in that they transfer heat from one spot to another rather than supplying heat directly to the water.Tankless/on-demand water heaters heat water on demand, rather than storing it in a storage tank.Tankless coil and indirect water heaters heat the water by drawing energy from your home’s heating system.

Thermal solar water heaters, which heat water by absorbing solar energy, make up the final type of water heater.Hot water heaters are also powered by a variety of different types of fuel.In addition to conventional storage water heaters, electric water heaters, tankless or demand-type types, and tankless indirect hot water heaters are among the most commonly utilized fuels.Natural gas may be used to fuel traditional storage, tankless or on-demand demand, tankless coil and indirect hot water heaters, among other things.

Oil, propane, geothermal energy, and solar energy are some of the additional fuel alternatives available.

Hot Water Heaters and Floors

Manufactured Home Parts & Accessories writes that you may install an electric hot water heater on a concrete floor, but that you should raise gas hot water heaters so that there is some gap between the bottom of the heater and the concrete floor to allow for air flow.This is due to the fact that certain gas water heaters feature pilot lights, which serve as a source of ignition.Raising the temperature of gas hot water heaters is an important step in helping to prevent fires.The Uniform Plumbing Code controls the installation and inspection of plumbing systems, and their countrywide standards are utilized to improve plumbing safety throughout the country.In accordance with the regulation, you must increase hot water heaters that are fuelled by an ignitable fuel such as gas or propane.

A minimum of 18 inches should be allowed between the flame or the sparking mechanism of a gas water heater and the ground.If your unit is a heat pump or an electric unit, you won’t have to bother about raising the temperature.It is also not necessary to raise the temperature of gas and electric hot water heaters that have sealed combustion chambers.The plumbing code can be difficult to understand, and other municipal construction rules may also be applicable.

Before you install a new hot water heater or replace an existing one, familiarize yourself with the following terms.

Conventional vs. Tankless Water Heaters

According to the specialists at Laury Heating, a typical water heater works by allowing water from your main line to fill the tank until it is full.The water is heated by a heating device located at the bottom of the tank, which is controlled by a thermostat.The temperature of the new water at the bottom is lower than that of the old water, and the hottest section of the water is at the top.Any time you turn on a hot water faucet in your home, the water is forced out of the tank through a heat-out pipe.Tankless water heaters only heat water when it is actually required, rather than storing it.

These water heaters are equipped with flow sensors, which activate when you switch on a hot water faucet.When a tap is turned on, the heater’s internal heat exchanger is warmed up, and water is forced through it and out the faucet.They reduce the need to maintain a full tank of water and save energy; nonetheless, they are more expensive than the alternatives.

Are water heaters required to be raised off the floor?

Currently, only older gas water heaters housed in a garage are needed to be elevated in accordance with the International Residential Code (IRC) and the Florida Building Code (FBC M1307.3).It is not required for electric water heaters or gas water heaters with a capacity of 30 to 50 gallons that were built after the middle of 2003.The code stipulates that ″appliances with an ignition source should be elevated not less than 18 inches (457 mm) above the floor in garages,″ and the objective of this restriction is to ensure the safety of those who work in the garage.If there is any gasoline leakage from an automobile parked in the garage, it releases combustible vapors that are heavier than air and settle towards the floor of the garage.An open flame near to the ground, such as the pilot light in a water heater, has the potential to cause an explosion and a subsequent fire in the house.

FVIR Water Heaters Exempted

However, despite the need to elevate any source of ignition above the ground level, several home fires were still blamed on the igniting of gasoline fumes in the garage.Therefore, the Consumer Product Safety Commission (CPSC) ruled that all 30, 40, and 50 gallon gas-fired water heaters made after July 1, 2003 must be equipped with Flammable Vapor Ignition Resistant (FVIR) technology to ensure that they do not catch fire.As a result, the water heater does not need to be elevated, and the code specifically exempts FVIR water heaters from being lifted in the manner seen in the photo at the top of this page.Specifically, according to the regulation, ″elevation of the ignition source is not necessary in the case of appliances that are designated as flammable vapor ignition-resistant.″ Even in the case of an FVIR water heater, there are certain jurisdictions that still need it to be elevated above the floor, so you should verify with your local building authorities before proceeding.An owner’s handbook and/or data plate on the side of a modern water heater will indicate whether or not it is Flammable Vapor Ignition Resistant, so you may check to see whether yours is equipped with this important safety feature.

If you can see a pilot light and a burner when you remove a cover plate from the base of the water heater, you have an older water heater that is not FVIR.For further information, please see our blog article What is an FVIR water heater?However, there are a handful of reasons why you might want to consider elevating your water heater regardless: A water heater that is raised makes it simpler to drain completely by gravity in order to flush the sediment collection out of the faucet at the bottom.The sediment accumulation that has occurred over several years is what generates the gurgling or rumbling sound that occurs each time the water heater begins to heat up.

To learn more about weird noises coming from your water heater, see our article Why is my water heater rumbling, gurgling, knocking or banging?for additional information about this.When the water heater is installed directly on a concrete floor, the moisture in the concrete will cause the base to corrode sooner than it would otherwise.Here is a compilation of further blog entries about WATER HEATERS that you may find useful: Is it possible to install a Temperature and Pressure Relief (TPR or T&P) valve so that it discharges horizontally?Gas water heaters are not permitted to be placed in some areas.

How High Off the Ground Should a Gas Water Heater Be Installed?

Have you ever walked into someone’s garage and observed that their water heater was elevated much above the floor?It may appear unusual, but it is simply a safety measure that has been implemented.In addition, if you decide to place a new tank water heater in your house (which we do not normally advocate), you should be aware of the rules that govern ground clearance requirements for such installations.

Height requirement for water heater installed in a garage

Natural gas tank water heaters are required to be erected at a minimum of 18 inches above the ground, according to the Uniform Plumbing Code.The fact that this measurement does not necessarily begin at the bottom of the unit is also vital to remember.Instead, there must be 18 inches of space between the pilot light or lighting system and the rest of the structure.The simplest method to accomplish this is to purchase a water heater stand, which should be robust enough to support the tank while it is fully filled with water.Why is it necessary for the water heater to be elevated 18 inches above the ground?

It is not for the purpose of avoiding being hit by a garage or other objects, as some people may believe.In the event that a combustible substance (such as gasoline or motor oil) spills on the garage floor, the clearance is intended to avoid a fire or explosion.Depending on whether you install an electric water heater or a gas water heater with a sealed combustion chamber, this requirement may or may not be applicable to you.Although the Uniform Plumbing Code is the national standard, it is equally vital to adhere to all applicable state and local standards and regulations.

What about indoor water heaters? 

According to national rules, gas tank water heaters placed inside do not need to be elevated above the ground by more than 18 inches from the ground.Again, make certain you adhere to all applicable rules, including state and municipal regulations, as well as the manufacturer’s installation guidelines.While it is still a good idea to lift an indoor water heater off the ground in case a flood occurs in the area where it is being installed (especially in a basement).In addition, you should install a drip tray under the unit to capture any water that leaks out of the tank, including water from the pressure release valve, and drain it.

Have a plumber install your water heater

  • Ground clearance of 18 inches is only one of several critical requirements and best practices for water heater installation that must be followed. For many homeowners, these rules might be confusing and difficult to comprehend in their entirety. When the water heater is installed incorrectly, it might malfunction or create a hazard such as a fire, among other things. As a result, it is preferable to leave water heater installation to trained and experienced specialists.

How to adjust your water heater temperature

No one enjoys taking a cold shower.Even worse is being scalded by hot water when you are using it in the shower.Maintaining the proper temperature on your water heater is vital not just for your health and safety, but it also allows you to save money on your power bill.Here’s how to regulate the temperature of your water heater to save money while also protecting your skin from sun damage.

The correct temperature range

    There are a number of reasons your water heater should be set within a specific range of temperatures. If it’s set too low, not only will your hot water feel lukewarm, at best, it can also lead to bacterial growth which can cause things like Legionnaires’ disease. This can be prevented by setting the water heater to a temperature where the bacteria Legionella cannot thrive. The Occupational Safety & Health Administration (OSHA) recommends water heaters be set to at least 140 degrees Fahrenheit (60 degrees Celsius) to minimize the growth of Legionella and other microorganisms.While you might be prone to just crank up the heat, water that is too hot is potentially more dangerous, especially if you have kids around the house. At 150 degrees Fahrenheit (66 degrees Celsius), it only takes two seconds to suffer third-degree burns. The Consumer Product Safety Commission (CPSC) recommends setting the water heater at no more than 120 degrees Fahrenheit (49 degrees Celsius) to prevent scalding. Not to mention, a water heater that is set too high can unnecessarily increase your electricity bill. Of course, every house is different. The further a faucet is from the water heater, the more heat will be lost as the water travels, especially if the pipes aren’t insulated. That means you might have to raise the temperature beyond the recommended 120 degrees Fahrenheit (49 degrees Celsius) to compensate.Use your best judgement for your family and household when setting thetemperature. It’s smart to stay within the range of 120 to 140 degreesFahrenheit (49 to 60 degrees Celsius). Make an adjustment, test it out and repeat until you settle on the perfect temperature setting for you home and water heater. Now playing: Watch this: Step inside CNET’s Guide to Smart Living 1:00

Adjusting water heater temperature

The interface used to control the temperature of a water heater will differ depending on the kind and model.Fortunately, the majority of water heater models can be modified in the same way.For example, most contemporary gas and electric water heaters are equipped with a thermostat concealed behind an insulated access panel.Electric water heaters are frequently equipped with two thermostats: one at the top of the tank and another at the bottom.Furthermore, most tankless water heaters include a display with a temperature reading as well as controls for altering the water heater’s temperature.

Regardless of the sort of water heater you have, you should always test the water before making any changes to it.Turn on the water in the bathroom or kitchen sink and let it to run until the water is completely hot before using.Then, to get an accurate reading, place a thermometer beneath the surface of the water.


The process of adjusting a tankless water heater is quite similar to the process of adjusting your air conditioning thermostat. Adjust the temperature by using the digital control panel, which may be adjusted up or down as desired.

Gas or electric water heaters

  • Some gas water heaters include a dial towards the bottom of the device that may be adjusted simply by turning it – no tools are required for this operation. Nonetheless, most current tank water heaters (whether gas or electric) require a bit more effort, but the process is still straightforward and should only take a few minutes. Turning off the water heater’s electricity at the circuit breaker is the first step.
  • To remove a thermostat(s), locate the access panel for the thermostat(s) and remove it using a screwdriver
  • Remove the insulation by peeling it back.
  • To adjust the thermostat, use a flathead screwdriver to turn it up or down. If your water heater has two thermostats, make sure they are both set to the same temperature. The temperature on the top thermostat should be a few degrees higher than on the bottom thermostat.
  • Replace the insulation and re-install the access panel, if necessary.
  • Reconnect the water heater’s power supply
  • It is possible that you may need to relight the pilot light on a gas water heater.

Once you’ve made the necessary adjustments, you should wait at least three hours before checking the water temperature once more.It is possible that you may need to make more modifications in order to get the desired temperature.If you’ve increased the temperature and are still getting chilly showers, it’s possible that your hot water heater has to be serviced or completely replaced.Is the energy efficiency of your home high?Here are five different methods to find out.

CNET’s Guide to Smart Living is a one-stop shop for tips, techniques, and guidelines to help you live a more intelligent life.

Should Hot Water Heaters Sit On The Floor?(Complete Guide)

Hot water heaters should not be placed directly on the floor.Although it is possible to place a water heater on the floor, the Uniform Plumbing Code requires that the tank be elevated above the ground at a minimum height of 18 inches above the ground surface.Purchasing a water heater stand is the most acceptable method of elevating your tank’s height.A water heater stand will do the trick, and they are robust enough to support the weight of the tank when it is fully charged.We may have incidents of gasoline or motor oil spilled on the floor, which may be dangerous if exposed to a spark from a fire.

As a result, the tank must be elevated to at least 18 inches from the ground.Our sealed combustion chambers house those gas and electric water heaters, so they do not need to be elevated because they are protected from external danger by the chamber’s seal.Others choose to use indoor water heaters, in which case they do not need to raise the tank, but it is still a good idea to adhere to your state and municipal laws as a safety precaution.In addition, it’s usually a good idea to raise your water heater and install a drip tray underneath it to catch any water that escapes from the tank.

That is not to say that the pressure release valve is exempt from this.

Do Water Heaters Have To Be Elevated?

In most cases, water heaters do not need to be raised.For example, if your gas water heaters are flammable vapor ignition-resistant, you may have them sit on the floor to conserve space (FVIR).For all electric water heaters, the same is true; they may also be mounted straight to the floor.People think that it is vital to elevate your water heater because gas water heaters that do not have FVIR are more prone to fire incidents if they are placed directly on the floor than when they are elevated.Well, that is no longer a concern since gas water heaters that have been validated by the FVIR may be installed directly on the floor without the risk of a fire spreading.

In the olden days, gas water heaters were needed to be elevated to a height of 18 inches from the ground because people were concerned that they might spontaneously combust if left unattended.Because ignitable liquids spilled on the floor may be ignited by the tank’s pilot light, the reality behind it was that a fire would result if they were allowed to burn.Consider the following scenario: you have your water heater put in the garage.If there is an accident and motor oil spills on the floor under the tank, the pilot light on the water heater might ignite the motor oil.

Although it is not required to raise your water heater, doing so is highly recommended for the following reasons: Comparing the situation when the tank is sitting directly on the floor, it is much easier to gain a complete view of the tank when it is time to check it.Another reason to raise your tank is to avoid the complications that might arise as a result of flooding.When the room, garage, or basement in which the water heater is located becomes flooded, it becomes quite simple to remove the flood water before it causes any harm to the water heater or other property.Another reason to elevate your water heater is to allow for better drainage.As a result of elevating the tank, complete draining is made possible, and it is this lower water in the tank that must be evacuated since it may contain impurities.

Can A Gas Water Heater Sit On Wood?  

Yes, it is possible to place a gas water heater on top of wood.However, it is not recommended that you sit on it.It is possible that the tank will develop a leak, in which case water would flow down the wood, weakening it if this occurs for an extended length of time.You will notice that your gas water heater tank is tilting to one side as a result of the damaged wood and the weight of the tank being too much for the wood to support.The impact on the wood will still be present even if one places a drain pan underneath it since the seeping water will pass through it.

As a result, it is not recommended to leave your water heater on the wood, especially if it is a gas water heater.

Is It Okay To Lay A Water Heater Down?

It is not acceptable to turn off your water heater.However, there are some instances in which it is necessary to transfer the water heater, maybe on its side rather than upright.Water heaters must be properly protected when they are turned on their sides, otherwise they risk having their metal casings damaged, or they risk having their glass linings crack or break.To put it another way, when you turn your water heater on its side, you must perform the following; Before you do anything else, make sure the water heater is switched off.You should turn off the breaker switch that is connected to the water heater before proceeding.

After that, you’ll shut off the water flow and then drain the tank completely.Disconnect the water line and the electrical supply, and then totally drain the tank.After you’ve finished, gently transfer the tank to the truck and deliver it to its new place.Nonetheless, it is recommended that your water heater be installed in an upright posture rather than on its side in order to prevent damage to the tank.

When you lay a water heater on its side, make sure it is sufficiently cushioned so that it does not harm the metal casing or the glass lining of the heater.Transportation your water heater on its side will be safer if you have the correct equipment and take the essential precautions.

What Should I Put Under My Water Heater?

It is necessary to put a drip pan underneath the tank in order to collect any water that drips from the tank.Drain pans are often installed underwater heaters in the majority of situations, depending on the position of the water heater itself.The majority of water heaters that are put in the attic or ceiling area require a drain pan to be fitted underneath the unit.Those placed in garages, on the other hand, are not required to include a drain pan in certain states.In addition, a drainpipe will need to be built in the drain pan to allow the water to drain to the outside of the home.

Because of the potential harm that leaking water might bring to your water heater, you must have a drain pan placed beneath it.The depth of the drain pan should not be less than 1 1/2 inches, which is the equivalent of 38 mm in width and length.In addition, the drain pan should be large enough to accommodate all of the condensed water from the tank as well as any leaking water from a leak.Consider the following scenario: you have put your water heater in your attic, and it develops a leak; as a result, water will pour down your walls.

If the leak is severe, you will need to take precautions to ensure that the water does not cause damage to the walls, which necessitates the use of a drain pan.If you do not have a drain pan and the leak persists for an extended length of time, it will have an adverse effect on the load-bearing capacity of the wall, which might result in it being damaged or, in the worst case scenario, collapsing.When selecting a pan to be placed beneath your water heater, you should take the following factors into consideration: The pan should be constructed of aluminum to ensure long-term durability, and the size of the pan is also important.

Should There Be Water In The Pan Under My Water Heater?  

No.There should be no water in your drain pan at this time.If you check your drain pan and see that there is water in it, this indicates that there is a leak in the water heater.The purpose of the water heater pan is to collect any little amounts of water that may be leaking from the water heater and securely drain it until the repairs are completed.It’s usually a good idea to check the tank on a regular basis to see if there is any leakage or dampness.

Drain pans are often considered to be insurance against any potential water damage.If your water heater is in perfect working order, the drain pan should always be dry, and if the water heater is having problems, the drain pan will constantly be wet, as seen in the image below.Some of the reasons why you could have water in your drain pan include the following: There is a problem with the drain valve.Drain valves are often situated under the water heater tank, where they can operate efficiently and without being obstructed by any other components.

As a result, if you inspect your water heater and observe water leaking from the nozzle at the bottom of your water heater, it is possible that the drain valve has been clogged with sediment.The drain valve is defective and must be replaced immediately if the leak persists after you have tightened the nozzle.The failure of your hot water tank might also be a cause of water leaking from your water heater tank.After a period of time of water collecting in your tank, certain sediments may begin to build at the bottom of your tank, which might cause internal harm to the water tank.These sediments may be so concentrated that they erode and shatter the metal, resulting in a leaking from the pipe.

  • The complete water heater will need to be replaced if this is the root cause of the leakage from its tank.

Are Short Water Heaters More Efficient?

Yes, short water heaters are more energy efficient than long water heaters.These water heaters are more energy efficient when compared to tall water heaters.Using a short water heater can help you save money on electricity costs while also conserving water use.Another advantage of small water heaters is that, when compared to tall water heaters, they provide the highest GPM count.Short water heaters, which can store up to 50 gallons of water and are typically between 30 and 49 inches tall, are most common.

Fifty gallons of water is sufficient to provide water for up to four persons in a home, which is a substantial amount of water.In addition, because of the larger vessel, short water heaters provide a significant volume of hot water on the first pull.They enable for more hot water to be drawn from the tank before the incoming cold water stratifies the whole tank of hot water.

Can A Water Heater Sit Directly On The Floor?

Yes, it is possible to install a water heater right on the floor.It is possible for a gas water heater to be installed directly on the floor if it is resistant to flammable vapor ignition (FVIR).Well, not all water heaters will perform optimally if they are put directly on the ground.The pilot flame beneath the water tank of a GE Gas water heater, for example, prevents the water heater from being put directly on the floor.When the pilot flame comes into touch with a combustible substance, such as spilled engine oil, it might cause a fire to ignite.

As a result, owing to the ignition mechanism situated beneath the tank, it is recommended that you have your GE Gas water heater elevated.Water heaters are only needed to be elevated if they operate on an ignitable fuel source; if they do not, they can be placed immediately on the floor.As long as the area is always dry and free of dust, you do not need to lift your electric water heater; it may just rest straight on the floor.


A water heater is a necessary household item in every given home, regardless of its size.It is normal for a conventional water heater tank to have an 8 to 12 year lifespan of efficient operation.An electric heat pump, a tankless water heater, and a traditional tank-style water heater are the three different types of water heaters available on the market.The typical tank water heater is the most often used water heater because of its storage capacity, which allows it to supply water for bathroom showers and faucets in the home.In most cases, it is advised that your water heater be elevated off the ground by at least 18 inches for a variety of reasons, the most of which are safety issues.

One more item that your water heater should always have is a drain pan put underneath it to allow for any leaking from the tank to flow into the drain pan and out to the outside of the building.Drain pans are useful in preventing mishaps caused by accumulating water under a leaky water heater tank, which may be hazardous.To summarize, water heaters are essential to our day-to-day home activities since they ensure that the water is always warm to the touch.

Tall Vs. Short Hot Water Heaters

  • The ability of the unit to provide hot water is not diminished by its height.
  • Your water heater comes in third position in terms of energy use and prices, behind only heating, cooling, and refrigeration systems.
  • When it comes to choosing a tall or short water heater, the usual guideline is ″if it ain’t busted, don’t change it.″ This is especially true when it comes to plumbing.
  • For example, if you have a tall water heater in your house and you need to replace it, you should choose a new tall water heater.

The same may be said for a water heater that is too short.Additionally, the distance between connecting pipes and the ceiling height of the area where the water heater will be put are important considerations to make.


  • Tall water heaters used in homes have a height ranging from 46 to around 60 inches in height.
  • Typically, they are cylinder-shaped and have a diameter ranging from 18 to roughly 21 inches.
  • They can hold anywhere from 30 to 100 gallons of water, depending on the model.
  • Tall water heaters are referred to as ″tall boys″ because of their height.

It is common for them to be put in homes that have a basement or garage where the unit’s height may be handled easily.In addition to the height of the tallboy water heater unit, the area must be large enough to handle the height required to connect a pipe on top of the unit to the home’s plumbing system, which may be around 40 inches high.The connecting pipe, on the other hand, may be modified and set to slant diagonally in order to accommodate the room’s ceiling height.


  • The height of short water heaters installed in residences ranges from 30 to 49 inches in height.
  • They have tanks that are broad and circular in shape, with diameters ranging from 20 to 26 inches.
  • Modest water heaters are referred to as ″low boys″ because of their short height.
  • They are frequently placed in homes that have a crawlspace instead of a basement, or inside of a closet within the home, as well as in the garage or attic of the home.

Low boys require a connecting pipe height of between 29 and 32 inches to be able to connect to the system.The majority of short water heaters used for ″whole home″ water heating have a storage capacity of between 30 and 50 gallons.The short water heaters, on the other hand, are capable of holding as little as 10 gallons of water.


  • The majority of small and tall water heaters are typical storage tank water heaters, which store water in a tank within the heater.
  • They can be put within a home’s interior spaces as well as in auxiliary regions such as a garage, basement, crawlspace, or attic, among other locations.
  • Either a tall boy water heater or a low boy water heater should be installed in a place that is near to the plumbing system.
  • They may be used with natural gas, propane, or electricity.

They can also be used with solar water heating systems or with a heat pump system that works in combination with a home’s heating and cooling systems to provide hot water on demand.However, while the plumbing height may be altered to accommodate a short or tall water heater, it is recommended that the pipes be installed vertically to allow for speedier delivery of hot water via the plumbing system and into the taps of the various bedrooms and bathrooms.


Height, gallon capacity, and the necessary height for plumbing connections are the most significant variables. Tall water heaters are approximately 16 inches higher than standard water heaters, may store up to 50 gallons more water, and require an additional 10 inches of height for plumbing connections. Aside from that, there is no discernible difference in performance between the two.

Water Heater On Bricks [Reasons & Processing]

  • It is possible that we will receive commissions for purchases made through the links in this post.
  • Water heater bottom rust that is not managed may be a disastrous problem to have to deal with in the long run.
  • Water heaters are also a source of concern due to the possibility of a fire.
  • What is the reasoning for putting water heaters atop bricks?

Placing a water heater on bricks is typically done to protect the bottom of the water heater from rusting.It protects the metal body from moisture, but that isn’t the only thing it does.Heaters that do not have FVIR cannot be installed directly on the ground.Masonry bricklayers are used in the prevention of heaters from posing a fire threat.The information presented above is only a small percentage of what we have prepared for you.In a step-by-step approach, we’ve gone over the reasons for employing them as well as the ways for doing so.

  • What are you waiting for?
  • Let’s get started!

Why Put a Water Heater On Bricks?

  • In most cases, water heaters are situated a few meters above the ground level.
  • Despite the fact that many individuals believe it is necessary, it is not.
  • On a daily basis, misconceptions about how to modify the water heater’s temperature level are created.
  • Let’s clear up any misunderstandings regarding what they are.

Gas water heaters that have been approved by the FVIR have no problem resting directly on the floor.However, this is not the case with gas heaters that have not been FVIR-approved.They must be installed at a minimum height of 18 inches above the ground.For the simple reason that heaters without FVIR can pose serious fire threats when left on the ground.Electric water heaters can be installed on the ground as well as on the wall.Some homeowners, however, prefer to have their heaters built above ground level when they are installing them.

  • Neither is it an absolutely necessary modification.
  • Some, however, believe that it is preferable to have it erected above the ground.
  • This is when the issue of brick enters the picture.
  • The water heater is raised above the ground with the help of bricks.

Moreover, it prevents rust from forming on the metal bottom of the heater.Let’s take a quick look at the chart below before making a decision on whether or not to utilize bricks.Identify the heating systems that are suitable for installation on the ground.

Using Bricks To Raise heater Off The Ground

Let’s say you wish to put bricks under the heater to help it run more efficiently. To successfully modify the height level of a structure, there are two approaches that may be used. In the case of water heaters that are mounted on their side, both ways are effective. It will be strong, and there will be no need to be concerned about the heater coming loose.

Method-1: Using Straps To Secure The Heater

  • Suppose you wish to put bricks beneath the heater to prevent it from overheating. To successfully modify the height level of a structure, there are two approaches. With regard to water heaters that are positioned on their side, both techniques are effective. You won’t have to worry about the heater slipping off because it will be solid.

Do you have everything you need? All right, let’s get down to business.

Step-1: Lay Down The Bricks

Place the bricks side by side in a single layer, so that they are not touching. Place the water heater on the bricklayer’s workbench now. Install a stud behind the heater and secure it to the wall with screws. Duct boards or metal sheets can be used as alternatives for wood.

Step-2: Attaching Straps

  • The majority of heaters require two straps to be secured to the wall.
  • For those searching for a nice strap kit, we recommend the following:-Now that you have the straps, we’ll connect them to the studs.
  • Some straps are equipped with screws and bolts that may be driven straight into the studs.
  • Others need you to drill a pilot hole first, after which you may attach the bolts.

The straps should be placed in the upper and lower thirds of the bottom tank, respectively.The bottom portion of the body should be elevated over the thermostat control.

Step-3: Binding The Straps

  • Make sure the heater is securely fastened with the straps and that it is not loose.
  • If the strap’s length has to be adjusted, use a Dremel to make the necessary cuts.
  • You may use the same Dremel that you used to cut the ducting for this project.
  • Because the strap is constructed of a material that is identical to the belt.

An additional hardware kit can be found at the end of the strap.It connects the straps together in the same way a belt would.There’s a bolt-on that has to be tightened down correctly.Repeat the same for the other strap as well.And that’s how you use straps to lock the heater’s place while placing brick beneath it to prevent it from moving.

Method-2: Mortaring The Bricks 

Rather than leaving a jumble of shaky brick layers in place, you may mortar them together. Placing the water heater atop the mortared block provides more stability and safety.

Step-1: Measurement

Measure and mark the space that will be required for the laying of bricks before you begin. Make a pencil mark around the outside of the space.

Step-2: Making Foundation For Mortaring Bricks

A timber frame can be built around the initial layer of brick to provide support. It is, however, completely optional. Apply a 1-1.5 inch layer of concrete to the area that has been marked out. Pour and level the concrete mixture according to the manufacturer’s instructions. Allow for thorough drying of the concrete before putting the bricks.

Step-3: Mortaring Bricks

Apply some mortar under the brick with the chisel once it has been placed. It should be placed on the cured concrete floor. This procedure should be repeated for each brick. For your water heater, four bricklayers will enough. If you want to raise the level any further, you may stack more bricks on top of it.

Step-4: Placing The Heater

Simply set the heater on top of the mortared bricklayer and turn it on. Because the base has now been strengthened, it may be placed with more ease. In order to increase safety, you may always attach straps to the heater. Hopefully, these solutions may be of use to you!


  • Is it possible to install an electric water heater on top of a concrete foundation?
  • Electric water heaters should not be installed directly on concrete floors, according to the answer.

Adjusting an Electric Hot Water Heater Temperature Thermostat Setting

  • The process of adjusting the temperature thermostat setting on an electric hot water heater is a little more difficult, but still pretty simple.
  • The vast majority of electric water heaters are equipped with two thermostats: an upper and a lower thermostat, both of which are placed beneath two control panels.
  • Setting both thermostats to the same temperature can help to guarantee that your electric water heater operates as effectively as possible.
  • One thing to keep in mind is that some tiny electric hot water heaters only have one thermostat.

Here’s how to adjust the temperature on your electric hot water heater thermostat:

Please keep in mind that you will want a screwdriver to execute the following procedures in order to alter the temperature of your water heater.

  1. Make sure your water heater is off by turning off the electricity. This may be accomplished by locating your circuit breaker and shutting off the electricity in the area surrounding your water heater
  2. Then, locate the thermostat(s) on your water heater and turn them on. Typically, they are located behind a control panel that is secured with screws. Remove the cover from the access panel using your screwdriver (s). To access the thermostat, you may need to remove the insulation from your heater if it is properly insulated. The thermostats will be controlled by a dial, and the dials will have a varying reading depending on the manufacturer of the heater.
  3. Once the control panel has been removed, you may change the temperature knobs to make the room hotter or colder according on your preferences in terms of temperature. Take care to set both thermostats to the same temperature setting if you have more than one.
  4. Replace the control panel covers and the screws with your screwdriver after they have been removed. After that, re-energize your water heater’s electrical system.
  5. After a few hours, check the temperature of your hot water again (about three to four). Continue to follow the above instructions until the water temperature reaches the required setting
  6. if it still does not, repeat them until the temperature reaches the ideal setting for your needs.

Other Considerations: Water Heater Thermostat Setting Safety

  • There is one thing you should be aware of: your water heater is fitted with something known as a temperature and pressure relief valve, sometimes known as a ″T&P valve.″ These can become worn out over time, and one sign that they should be replaced is the presence of water leaking through.
  • This is a very crucial safety feature.
  • In the event that your unit is outdated or if your hot water heater pressure relief valve leaks after being replaced, get it examined by a competent plumber.

Why Your Hot Water Doesn’t Last Long Enough

  • Have you ever gotten into a hot shower only to have it turn icy cold seconds later? The worst part is that it happens every day, whether it’s the alarm in the morning or the bedtime routine at night. Here are a few tips and suggestions from Warner Service Inc. in order to keep the hot water flowing for longer: Increase the temperature setting on the hot water heater. One of the most straightforward methods to extend the duration of a hot shower is to use less hot water while the water is still at a high temperature. To accomplish this, raise the temperature setting on the thermostat that is linked to the hot water heater tank, as shown below. (This is not the thermostat mounted on the wall.)
  • Shower with a low-flow showerhead. If you haven’t changed your shower head yet, consider switching to a low-flow one. The apertures in these plumbing equipment are smaller, allowing the water to exit more quickly. This naturally pressurizes the water and drives it out at a slower rate than would otherwise be the case.
  • Keep an eye out for alternate sources of hot water in your home. The shower isn’t the only spot in your house where you’ll find hot water. Even if the dishwasher and washing machine are not in use at the same time, they have an impact on the amount of hot water available. Washing the dishes after a hot shower and doing laundry with cold water are good ideas. Insulate the domestic pipes as well. In order to enhance the insulation of home hot water pipes, a plumbing specialist should be called in. Hot water leaves the heating tank and travels through pipes to the shower, washing machine, and dishwasher, among other places to use. The water can quickly lose its heat while traveling through pipe to reach faucets or shower heads if the piping is not properly insulated. Inspect the heating components. The hot water heater might be the source of the plumbing issue with the hot water, if that is the case. Water will not be heated to the temperature specified on the tank’s thermostat if the heating element is not operating properly. The heating element’s size varies based on the type of energy source it employs (gas, solar, or electric). Elements may be simply updated and frequently enhance the overall operation of the hot water system.
  • Perform regular maintenance on the hot water tank
  • A badly maintained hot water tank is one of the most common plumbing problems associated with a hot water system. Sediment and rust accumulate in the tank’s inside. This has the effect of lowering the water quality and slowing the effects of the heating element. These plumbing issues may be resolved with a simple draining and cleaning procedure. A plumbing specialist can execute this job in a short amount of time.
  • The hot water tank should be replaced or supplemented. If your hot water system isn’t operating properly, you should consider upgrading the complete system. Even though many hot water systems only have a single heater tank, it is feasible to install a second tank in order to boost performance. Additionally, modern heater tanks are a better alternative for older homes that require renovations. Consider installing a tankless water heater. The water heater is responsible for providing your home with a plumbing system that provides hot water for all of your needs. Tankless water heaters are more energy efficient and help you save money on your utility costs.
