Read This Before You Buy a Tankless Water Heater
Consider the following: The method used by the majority of houses in this nation to heat water is ridiculously inefficient. Every year, we fill up large storage tanks of 40- to 50-gallon capacity with water and then continuously pump energy into them to ensure that we have hot water available anytime we want it. But, unfortunately, this is not always the case. The wait for the tank to reheat might be lengthy if a teenager is taking a long shower or the spouse is enjoying a long soak in the tub.
Is there a chance of a leak?
Tankless Water Heater Installation: Is It Worth It?
Investing in a tankless water heater has a number of benefits, as detailed above. It creates hot water just when you use it and for as long as you require it, resulting in a reduction of 27 to 50% in fuel expenses when compared to tank-type heaters. (A typical gas-fired tank wastes 40 to 50% of the fuel it burns, according to the manufacturer.) As a result, there is virtually little danger of a catastrophic leak occurring because there is no tank to collapse. Furthermore, since their introduction in the United States in the 1990s, tankless heaters have become increasingly sophisticated, with features such as built-in recirculating pumps (which provide “instant” hot water) and wireless connectivity, which alerts you via smartphone when a unit requires servicing.
Our tankless water heater guide will explain how they function, what you should know before purchasing one (and before the installation comes), and the idiosyncrasies of how they operate so that you won’t be caught off guard if you decide to go tankless.
How Does a Tankless Water Heater Work?
Doug Adams created the illustration.
- It all starts with the first turn of the hot-water faucet (1). A flow sensor (2) detects the presence of water entering the heater and sends a signal to the control panel, causing the heater to begin generating hot water. During operation of a natural-gas-fueled unit, thecontrol panel (3) activates thefan (4), which pulls in outside air, opens the gas valve (5), which allows the gas to flow into the unit, and ignites the burner (6). In order to transmit heat from the flames to water passing through the exchanger’s tubing, a heat exchanger (number 7) is used. The mixing valve (8) regulates the temperature of the superheated water that exits the exchanger. Whenever the temperature sensor (9) detects water temperatures that are too high or too low for the intended setting, the panel will modify the gas valve, the mixing valve, and the flow-regulating water valve (10) in accordance with the results. Ventilation is provided by a sealedvent (11) (or a couple of vents) via a roof or exterior wall, which removes exhaust gases and supplies combustion air to the burner.

What to Know About Tankless Water Heaters
Thanks to Noritz for the use of his photo.
How Much Does a Tankless Water Heater Cost?
Prices range from approximately $170 for modest gas-fired units to more than $2,000 for high-output heaters that can serve two showers at the same time; $1,000 is a reasonable starting point for most buyers. Electric heaters without a tank range in price from $90 to $900. The expenses of a first-time installation are higher than the price of a simple tank replacement. Electric tankless water heater installation (see item below headed “Installing an Electric Tankless Water Heater”).
How to Install a Tankless Water Heater
This is a work that should be left to the professionals, since it entails creating leak-free water, vent, and gas connections in the case of gas or propane units, or upgrading the wiring and circuit-breaker panel in the case of electric units, and it is best left to the professionals.
Tankless Water Heater Maintenance
Sign up to have a professional do an annual service that includes cleaning or replacing water and air filters, as well as inspecting the burner’s operation.
The use of a vinegar flush every 500 hours in places with hard water prevents mineral accumulation, known as scale, from blocking the heat exchanger. That 20-minute task may be completed by a professional or by a homeowner.

Pros and Cons of Tankless Water Heaters
Thanks to Noritz for the use of his photo.
PRO: They’re Compact
As a result of new federal requirements requiring stronger insulation to decrease standby heat loss, the size of newer tank-type water heaters has increased. Consequently, they may not be able to fit into locations where an older heater with the same capacity might. Tankless gas heaters are approximately the size of a suitcase and are mounted on the wall.
PRO: They’re Safer
A tank-type heater, on the other hand, may leak and spill gallons of water if it springs a leak, but it will not house Legionella germs or topple over in an earthquake. The air supply and exhaust vents are also closed to prevent backdrafting, which would otherwise allow carbon monoxide to enter the house.
PRO: They’re Easy to Winterize
Owners of vacation homes are well aware of how long it takes to drain a water-heating tank prior to closing up a house for the season. An electric compressor may drain a tankless heater in a matter of seconds, after which it can simply be unplugged.
CON: They’re Sensitive to Slow Flow
These devices automatically shut off if there is too much scale accumulation in the pipes, or if the aerators in the faucets and showerheads get blocked, or if a turned-down faucet limits water flow to around 0.3 gpm.
CON: The Payback Takes Awhile
An annual savings of only around $100 for a household using a $1,000 tankless gas heater vs a $400 tank-type heater is possible, depending on how efficient the heater is and how much hot water is utilized. The savings, however, begin to accrue after six years, when many tanks are reaching the end of their useful lives due to the extended lifespan of tankless gas systems.
New Tankless Water Heater Technology
Thanks to Noritz for the use of his photo. The advancement of tankless technology is ongoing. Here are a few of the most recent enhancements:
Condensing gas heaters can extract up to 96 percent of the heat from a fuel, which is a 17 percent improvement over first-generation tankless devices. This is possible because of a second heat exchanger, which collects a large portion of the exhaust heat before it exits the vent. In addition to being around 25% more expensive than noncondensing heaters, condensing heaters produce acidic condensate that must be neutralized. If a heater doesn’t come with a built-in neutralizing cartridge, the installation will have to install one after the fact.
Instant Hot Water
Despite the fact that tankless water heaters heat water in around 15 seconds, you must still wait for the hot water to reach your shower head or faucet, just as you would with a tank-type heater. The recirculation pump should be used when the distance between the heater and the fixture is greater than 50 feet. This will conserve water and minimize the amount of time spent waiting. It is this pump that pushes the cold water in the pipes back through the heater.
The pump can be activated by a timer, a push button, a motion sensor, a smart speaker, or a smartphone (see illustration above). The pump shuts off after approximately a minute, and you may start using hot water immediately after opening the faucet.
Tankless systems with digital connectivity let you to control the temperature as well as monitor gas and hot-water use from your mobile device. Furthermore, the device is capable of identifying the cause of a problem. Please communicate this information to your plumber so that he or she may arrive on the job site knowing exactly what has to be done. This function also eliminates the need for any guessing when it comes to determining when it is time to descale.
Tankless Water Heater Rebates: A Great Way to Save
Temperature control and monitoring of gas and hot-water use are possible with tankless systems that have digital connection. The device is also capable of identifying the cause of a problem. Provide that information to your plumber, and he or she will be able to arrive on the job site knowing exactly what is required. Having that function also takes the guesswork out of knowing when it’s time to descale your aquarium.
What Size Tankless Water Heater Do I Need?
Here’s how the specialists ensure that your water heater produces adequate hot water: 1. A large burst of BTUs is required for a tankless heater to convert cold water into hot water in a matter of seconds. However, if a heater’s Btu output is insufficient to meet demand, it will reduce the flow rate or, in the worst scenario, offer tepid water. A plumber considers three aspects when determining whether or not a heater will be able to satisfy the demands of a household:
- The temperature of the water that enters the heater
- The maximum demand for hot water expressed in gallons per minute (gpm)
- The efficiency of the heater, as shown by its Uniform Energy Factor, which may be found in the product specifications
- The first step is as follows: A professional determines how many Btus per gallon of water heater is required to increase the incoming water temperature to 120 degrees (see the map on the next slide)
- Flow rates for all of the appliances and fixtures that may be consuming hot water at the same time are added together to form peak demand, which is calculated as follows: (These rates are detailed in the next slide.) As a result of not bathing or washing in 120-degree water, we save around 20% on our overall use. Water-saving fixtures and appliances, as well as delaying laundry while the shower is in use, can help you minimize peak consumption. In the calculation, the total Btu production is computed by inserting the Btus-per-gallon and peak-demand amounts in at different points along the way. If the difference in output is between two models, go with the one with the greater Btu rating to save money. You’ll also need two smaller units that function in tandem if your output is greater than 198,000 Btus, which is the limit for domestic gas heaters.
Btus Output Estimate
Not interested in completing the calculations? Make a rough estimate of how much heater output you’ll want using these statistics.
- The following figures are for one bathroom for one to two people: 140,000 Btus
- Two bathrooms for two to three people: 190,000 Btus
- Three bathrooms for three to five people: 380,000 Btus
Btus Per Gallon by Region
- Kitchen or bath faucets should flow at 1.5–2.2 gpm
- Tub filler faucets should flow at 4 gpm
- Dishwasher: 1–2.5 gpm
- Washing machine: 1.5–3 gpm
- Showerhead should flow at 1.25–2.5 gpm
How to Determine gpm?
To get the real gpm of a fixture, time how many seconds it takes to fill a bucket to the 1-quart mark and multiply that time by the number of gpm. gpm is calculated by dividing 15 by the number of seconds in a minute.
Electric Tankless Water Heater Facts
Thanks to Stiebel and Eltron for their assistance. In addition to gas lines and propane tanks, tankless water heaters operated by electricity can provide the benefits of on-demand hot water to homes that do not have them. Compared to gas or propane tankless heaters, these systems, which heat water using thick copper rods, are significantly quieter and roughly a third smaller in size. And because they do not require vents, they can be fitted practically anyplace, even beneath sinks and in small closets, without compromising performance.
In locations with warm groundwater, that amount of hot water may be sufficient to feed a whole house; but, in colder climates, they are better suited to point-of-use service, where the demand for hot water does not become excessive.
Furthermore, electric heaters have a lifespan that is approximately half that of gas heaters: Warranty periods typically range from three to five years.
As soon as the heating elements fail, it is frequently more expensive to replace the complete heater than it is to simply replace the heating elements.
Tankless Water Heater Installation
Doug Adams created the illustration. What you and your plumber should look for before the installation day is as follows:
If you want your tankless heater to work effectively, you must connect it to a gas supply line that supplies enough volume at a high enough pressure to run the burner. In many circumstances, this will need increasing the diameter of the supply pipe to 3-4 inches in diameter. Furthermore, if the pressure is insufficient, the gas provider will be required to change the regulator on the meter. For your information, some tankless systems, like as ones manufactured by Rheem, are capable of working with a regular 12-inch gas line as long as it is not more than 24 feet in length.
Tankless gas heaters that do not condense employ stainless-steel vents that can resist high exhaust temperatures. Condensing systems feature a cooler exhaust and use PVC pipes, which are less costly than other types of exhaust. Installing a concentric vent, which has an exhaust pipe inside a larger air-intake pipe, is easier than installing a traditional vent since only one hole in the wall needs to be made. As a point of reference, vent runs have traditionally been limited to a maximum of 10 feet.
Heat transmission is slowed and water flow is restricted when scale deposits accumulate in a heat exchanger (or on electric heating components) over time. If you currently have whole-house water softening, scale will not be an issue for you. However, if your water is not being softened and its hardness surpasses 120 milligrams per liter, it is worthwhile to invest in a treatment system to remove the hardness. For your information, a specific, point-of-use cartridge, such as the TAC-ler water conditioner (Stiebel Eltron), can be used to change the hardness of water without the use of salt or other chemicals.
Outdoor Tankless Water Heater
Matt Risinger captured this image. If your environment and local rules allow it, think about the advantages of hanging a heater outside in the winter.
- Saves space: You won’t have to create place for another appliance in your home as a result of this. Installation is straightforward: Because of the built-in exhaust vent, there is no need to drill a large hole (or two) through the side of the building. Service is simple: A plumber may come to your home at any time, whether or not you are there. However, take in mind the following: Regulations governing construction: If you want to install it outside, you may require approval from your local building department. Weather conditions that are cold: Even at temperatures as low as 22 degrees Fahrenheit, internal heaters keep components warm, but exposed water lines must be insulated and covered with heat tape that activates automatically in freezing conditions. Southern states are less concerned about frozen pipes than those located north of the Mason-Dixon Line.

How Tankless Water Heaters Work
Known variously as demand type, on-demand, or instantaneous water heaters, these appliances heat water directly, eliminating the need to store water. A flow detecting device is installed in a tankless heater, and it is triggered anytime the hot water tap is opened. A gas burner or an electric element is used to heat the water, which is then sent to the various locations in your home where it is needed. You won’t have to worry about running out of hot water because there isn’t a tank that has to be filled.
Advantages Of Tankless Water Heaters
- They are more compact than typical storage heaters, are wall-mounted, and do not take up any floor space when not in use. As a result of their size, they can be particularly appealing in houses where space is limited
- They can also help you save money on your energy bills. According to the United States Department of Energy, heating water accounts for around 30% of a family’s total energy use. It is possible to save up to 50% on these expenditures by installing a tankless water heater, resulting in an average yearly savings of $80. Tankless water heaters are also more durable and less likely to malfunction, resulting in potentially disastrous flooding in your house. Compared to traditional water heaters, tankless systems have a lifespan that is about twice as long – 20 years or more.
Disadvantages Of Tankless Water Heaters
- Tankless units are more costly than conventional units. It will cost around the same as a standard tank type to purchase an electric tankless heater, however a gas tankless heater would cost between $1,000 to $1,200. The national average for tankless unit installation is somewhat more than $1,700, which is in addition to the original cost of the unit. A safe vent must be created for a gas unit to prevent carbon monoxide from collecting within the property in many circumstances. Existing plumbing must also be expanded or moved in many cases. Tankless water heaters do not provide “instant hot water,” even when energy savings are taken into consideration
- For many households, it will take around 20 years to completely return their expenditures. It is not always the case that a tankless water heater delivers hot water to your faucet any faster than a traditional water heater, contrary to common belief. In fact, a tankless device may be more time consuming. It takes some time for the tankless unit’s heating element to warm up the water before it can be delivered to the faucet
- The amount of hot water that can be delivered is limited by the unit’s ability to heat the water. It is typical for tankless water heaters to provide 2-5 gallon-per-minute flows of hot water, which may not be sufficient for several simultaneous uses of hot water in your home. For example, having a shower and running the dishwasher at the same time may cause a tankless water heater to reach its maximum capacity and fail. Comparing tankless versions, especially if you live in a multi-person home, is important. Pay close attention to the gallons per minute (GPM) flow rate of each type. The bigger the number of users and the greater the number of simultaneous usage options, the higher the GPM requirement. In order to satisfy the needs of a big home, one alternative is to install many tankless units
- However, this can become quite costly over time. It is possible that tankless water heaters will not provide hot water during a power outage. Tankless water heaters, in contrast to traditional water heaters, do not provide a backup hot water supply in emergency scenarios
- Tankless systems are also subject to failure owing to hard water. Hard water is a concern for all water heaters, but it is particularly challenging for tankless water heaters. They should be completely emptied and their filters updated on a monthly basis. They also require frequent flushing to function properly. (Tank units only need to be flushed once or twice a year, at most.) If you don’t take the necessary precautions, hard water can completely ruin a tankless water heater in as little as two years. In addition, failing to adhere to these maintenance requirements may result in the voiding of the manufacturer’s guarantee
- Tankless devices are hard to maintain. Investigate the interior workings of a common tankless water heater or air conditioner. As a result of all the complex technologies tankless water heaters rely on, it is easy to understand how much may possibly go wrong.
Gas or Electric
Electric tankless water heaters are significantly less expensive than their gas counterparts. Installation is less complicated and less expensive, and they are often less difficult to maintain than gas-powered ones. Only a few handful, however, have the capability of serving many locations at the same time. Gas units are available in a wide range of types and sizes for both residential and commercial applications, with outputs ranging from 130,000 to 380,000 BTUs in certain cases. More BTUs equate to more heating capacity.
- As a result, your home’s gas pipe, meter, and main line to the meter may not be correctly proportioned, necessitating a costly reconfiguration and installation of new equipment.
- The total energy efficiency of a tankless water heater is assessed using an energy factor (EF) rating, which is available for both gas and electric types.
- Tankless water heater energy factors now range between.64 and.91 for gas-fired devices, and up to.99 for electric versions, depending on the manufacturer.
- For a home of one or two persons, a tankless electric unit will most likely be more than sufficient.
Water Heater Protection
Whatever method you use to fulfill your household’s hot water requirements, you’ll want to make sure that the investment you’ve made in your water heater is protected. That entails completing the preventative water heater maintenance advised by the manufacturer, as well as routinely emptying the tank (or lines) to remove potentially harmful silt and scale. Consider obtaining an American Home Shield® Water Heater Home Warranty to help reduce the expenses involved with the repair and replacement of your water heater even more.

The sort of equipment you choose will have a significant impact on the overall cost of your project. Single-point electric units cost around $150 apiece, and a high-end gas model for the entire house may cost more than $1,500.
|Tankless Type||Average Unit Cost|
|Natural Gas or Propane||$1,000 – $1,500|
|Electric||$500 – $1,500|
|Solar||$1,400 – $6,000|
First and foremost, you must determine what sort of unit you will require.
- Noritz gas tankless unit with a BTU output of 199,000: A typical family with many bathrooms will be able to get by with this amount. It might take up to ten hours to complete the installation. Installation of suitable ventilation to avoid carbon monoxide poisoning, as well as the modification of the size of gas lines and fittings, will be more expensive in terms of labor. Model with an electric motor and a point-of-use interface: This is something that can be fitted under the sink. Installation takes an average of about two hours. It is necessary to have an electric timer, an outlet, and supply lines.
Whole House or Single Point
Tankless systems that are installed at a single point, or at a “point of use,” are those that are installed expressly by and for individual appliances and faucets that require them. They are quite simple to install and range in price from $100 to $300 per unit. They will be more efficient than utilizing a single one for the entire home because the water will only travel a small distance and will thus be wasted less frequently. The fact that they work independently of one another makes these single point systems particularly helpful in homes with several bathrooms and appliances.
However, one whole-house unit will be plenty for an average-sized home with consistent consumption throughout the day. Village Plumbing, LLC is based in Henderson, Nevada. In Las Vegas, gas tankless water heaters cost on average between $800 and $1,500.
Natural Gas or Propane Water Heaters
Installation of natural gas and propane models often costs between $1,000 and $1,500. While all of these types of gas will feed your system in a similar manner, there are some significant variations in the costs of purchase and operation between the two. propane must be purchased separately from natural gas since it is dependent on a utility supply line to be available. If you reside within a specific distance of a natural gas pipeline, you may be obliged to connect to it to heat your home. This isn’t a problem for the vast majority of homeowners.
Propane, on the other hand, is a more environmentally friendly and energy-efficient fuel that has a larger BTU capacity than natural gas.
They are also available in a variety of outputs ranging from 140,000 BTUs to 380,000 BTUs and in both residential and commercial categories.
Electric Tankless Water Heater Prices
240V 80 Amp hard-wired electrical service is required for electric whole-house tankless water heaters, which means your home must have a minimum of 150 Amp of electrical service to run all of the equipment. Cati O’Keefe is an expert home builder and contributor to the Home BuildingSustainability website. Electric variants are less costly than gas counterparts, with installation costs ranging from $800 to $1,500 on average. Because there is no requirement for venting, the installation work required is less difficult as compared to gas types.
In comparison to a tank-based unit, the tankless electric unit is 20 percent to 30 percent more energy efficient and produces no greenhouse emissions.
In most cases, electricians charge between $50 and $100 per hour.
- Electric hybrid water heaters are initially more expensive than ordinary electric ones, but they heat water more quickly than conventional electric models. Despite the fact that they are not considered tankless, they have many of the characteristics of a tankless system: They do not require any ventilation and are extremely cost-effective. However, they are only available in versions with a maximum BTU output of 8,700. Electric Models for Point-of-Use: $100 to $300 per unit- These have a number of appealing characteristics, including as their price and ease of installation. Aside from that, they are quite easy to use beneath sinks and in compact spaces, including near washing machines. This is a fantastic alternative for folks who want compact units for campers, boats, and other modest restroom requirements. They are non-corrosive, insulating, visually appealing, and light-weight in design. They contribute to water conservation by easily heating and delivering it swiftly
Find a Pro to Get Your Heater Installed
Solar heaters range in price from $1,700 to $5,000 to install. Prices have been reported to go as high as $13,000. These approaches, on the other hand, produce some of the biggest returns. First and foremost, they are eligible for the 30 percent tax credit. For a $6,000 installation, that equates to $1,800 in return. Second, studies have shown that they may save water heating costs by 50 percent to 80 percent, depending on the model. Tankless heaters can be used in conjunction with solar power systems to maximize energy savings.
Solar water tanks can be used to store hot water collected by solar collectors, which can then be utilized by the tankless water heater in the residence. The solar-energy components will have a high initial outlay of money.
Another aspect that will have an impact on expenses is a discount that is being provided on solar-electric equipment. Solar water heaters are eligible for a 30 percent tax credit on the cost of installation from the federal government. More information on the solar tax credit may be found at Energy Star. Inquire with your installer about tax credits and manufacturer rebates, as well as other financial incentives.

Choosing the Right Tankless Water Heater
“The advantage of using a tankless water heater is that you are avoiding any liability from leaks. We receive calls on a regular basis from customers whose conventional tank heaters have failed. Even the new ones fail since they are only capable of carrying 50, 40, or 100 gallons of water each. That leak might cause substantial harm if you’re on vacation and it happens to you. The advantage of using a tankless system is that you won’t have to worry about it.” Twin Home Experts is owned and operated by Jim Schuelke in Phoenix, Arizona.
So, how can customers choose which one is the best fit for their needs and preferences?
The flow rate is measured by counting the number of gallons that are produced every minute (gpm).

Pros of Tankless Units
This is not a project that the ordinary do-it-yourself homeowner should attempt. Many homes will need to be modified in order to suit this system, which may need the installation of new wiring or gas lines, the installation of new plumbing and fittings, and the rebuilding of drywall. This task must be conducted by a qualified professional in some areas, which is required by law. This is due to building rules governing carbon monoxide emissions, heat resistance, ventilation, and state-specific codes, such as seismic straps in California, among other things.
Additionally, they may make certain that you have the proper equipment for your property.
Using a professional ensures that the job is completed quickly and accurately, preventing your house from becoming flooded while you wait for a plumbing permit.

The payback time for these products is rather lengthy. Despite the fact that they are expected to endure for 20 years, it will take around 20 years for your energy savings to match your initial outlay.
So the value of these models is determined by their use to you and their potential utility in attracting future home purchasers to your neighborhood. By selecting the most appropriate model for your consumption requirements, you may increase the return on your investment.
Are tankless hot water heaters better?
The advantages of these models over conventional models are numerous. They save water by heating as they go, and they can help you save money on your energy bills. As a result, they are more durable and require less maintenance than conventional tanks since they do not store water, which may erode tank material and create leaks.
Do tankless hot water heaters work without electricity?

2022 Average Tankless Water Heater Installation Cost
Water heaters are classified into two categories: tank-style and tankless-style water heaters. In most cases, installing a typical tank-style water heater costs between $350 and $2,000, which is far cheaper than the $2,000 – $5,000 price tag associated with installing a tankless unit.
|Type of water heater||Average water heater cost||Average installation cost|
|Gas water heater with storage tank||$650 – $900||$350 – $2,000|
|Electric water heater with storage tank||$300 – $700||$350 – $2,000|
|Gas tankless water heater||$200 – $1,300||$2,000 – $5,000|
|Electric tankless water heater||$250 – $700||$2,000 – $5,000|
Despite the fact that tank systems are often easier and less expensive to install, a tankless type may be less expensive in the long run. Because they heat water on demand, tankless water heaters can help you save money on your energy bills. In fact, they can save households as much as $100 per year over the course of their lifetime. Because they are more labor-intensive to install, it is beneficial to be aware of the advantages and disadvantages of each before deciding which heater is best for you and your household:
Tank-style hot water heaters
Traditionally, a tank-type water heater has been the preferred water heater model. In a tank system, a predetermined amount of hot water is stored in a storage tank that is available for use at any time. It depends on how much hot water you anticipate your home will use that you choose a tank that is between 20 and 80 gallons in capacity. The most often seen tank capacity is 40 gallons. Larger tanks are often more expensive than smaller ones. Because a tank system ensures that hot water is available at all times, it necessitates the continuous use of gas or electricity.
If you have a tank system and consume a large amount of hot water at once, you may run out of hot water and be forced to wait until the system can heat additional water and store it in your tank.
Consider a bigger storage tank or a tankless hot water heater if your hot water heater is constantly running out of capacity.
Tankless hot water heaters
A tankless system heats water as it travels through the system, thanks to the use of a heat exchanger. Water is heated on demand, which means that it is heated just when you need it, rather than being heated in preparation. Water is heated and then sent via your pipes to your sink, shower, or washing machine where it is put to use by you. With a high flow rate, which is defined as the number of gallons your water heater can heat in one minute, you will be considerably less likely to run out of hot water.
Electric tankless water heaters are often $500 to $1,000 less expensive than gas tankless water heaters, despite the fact that gas tankless systems heat water more quickly.
Finally, while tankless types are often more expensive to acquire and install, they are typically more energy-efficient in operation.
Tankless Water Heater Installation
A tankless hot water heater differs from a standard gas water heater in that it only heats water when it is required; there is no tank, and therefore no energy is spent heating water that is not required. A tankless water heater in your Maryland house will provide you with hot water on demand, which means you will never run out of hot water in your home again. Furthermore, because the compact device is attached on your wall, it frees up the area that would otherwise be taken up by a standard water heater.
EfficiencySavings of Tankless Water Heaters
In addition to being one of the most energy-efficient water heaters available, a gas tankless water heater utilizes just the energy required to heat the water when it is needed. This product is an excellent energy-efficient solution for your house, especially in light of rising energy expenses and increased environmental consciousness among the general public. There are several advantages to purchasing a gas tankless water heater, including the following:
- Water heaters that use less energy
- Water that is always hot
- Tankless systems are simple to operate and have a longer life expectancy (the typical tankless system lasts 20 years). There is no tank to leak
- It conserves space
- Temperature control that is precise
- System that can diagnose itself
What Size Tankless Water Heater Do You Need?
Tankless water heaters operate in a different manner than typical water heaters, according to the majority of experienced plumbers. Despite the fact that they are available in a variety of sizes, the size of tankless water heaters is determined by the number of gallons of hot water they can supply every minute rather than the number of total gallons of water they can hold. Heaters that use the traditional method heat and store hot water in a tank until it is needed. Tankless water heaters only heat water when it is actually required to do so.

How to Install a Tankless Water Heater
Instructions from a professional on how to remove an old water heater tank, prepare the area for installation of a tankless water heater, and finally install the tankless water heater Because it does not store a large volume of heated water, a tankless water heater, also known as an on-demand water heater, saves money over a traditional water heater. Essentially, it serves to provide hot water on demand, so you won’t have to worry about the shower suddenly becoming chilly. The process of installing a gas tankless water heater consists of mounting the unit, connecting the gas and water lines, and installing a flue.
- Therefore, it may not function properly in a household where two or three showers may be running at the same time, as an example.
- It is both compact and highly efficient to use a tankless water heater.
- The following skills are required if you choose to do the job yourself: shutting off the water to your house (seeHow to Shut Off the Water to Fixtures) and cutting into and connecting new fittings and pipes to your supply pipes (if you have copper pipes, seeCuttingJoining Copper Pipe).
- There is also the need for a gas line and an electrical connection to a 120-volt circuit.
- It is not necessary to vent an indoor electric tankless water heater to the outside because it is contained within the home.
- It can either be plugged into a 240-volt outlet or directly wired to a power source such as a generator.
Tankless Water Heater Preparation
Remember to complete all essential preparations before disconnecting and removing your present water heater; you don’t want to be without hot water for a week or two while you wait for any plumbing, electrical, or vent work to be completed. If you are installing a new gas unit, you should determine whether you need to upgrade your gas meter. Because the unit consumes a considerable amount of BTUs, it is possible that your meter does not have the capacity to feed it in addition to the other gas-using appliances in your home.
- Request that the gas provider inspect your new unit to ensure that it is receiving the appropriate amount of manifold pressure for it.
- It is better to employ a professional plumber to install a new gas line if you need to replace an existing one.
- This will save you time and money.
- The fact that a tankless water heater generates a significant amount of condensation and pushes air out with a fan necessitates the installation of category II stainless-steel exhaust pipe with firmly sealed silicon joints, as seen in the second video below.
- A damper is an excellent addition for those who live in colder climates since it prevents chilly air from re-entering the home.
- Floor drains and utility sinks should be used to dispose of the excess liquid.
- In addition to gas, a gas unit requires 120-volt electrical power.
- You can watch this wonderful video from This Old House, which will provide you with an excellent explanation of the many stages involved in installing a tankless water heater.
- He makes the decision to remove and replace his malfunctioning water heater with a tankless water heater, and he guides us through the entire procedure with his hands on assistance.
- Codes demand that a subpanel (which may or may not be included with the unit) be erected next to the unit in order to comply.
Connect the wire to the subpanel and then from the subpanel to the unit, starting at the unit. It is essential that the electricity to the water heater’s circuit is turned off at all times while the work is being performed. +Find a Water Heater Installation Specialist in Your Area
Removing the Old Water Heater
In the majority of circumstances, a new tankless water heater will be installed in lieu of an existing storage water heater. In Ron Hazelton’s video above, he refers to our website for the directions, which are as follows: How to Flush or Drain a Water Heater (with Pictures). In order to remove the old water heater, turn off the valves on the two water lines (one for the input and one for the output) that lead into the existing water heater and disconnect them. To remove and detach the water heater’s lines from the water heater, use channel-type pliers or a pipe wrench.
- Drain the tank by opening the drain valve located at the bottom.
- Don Vandervort writes for HomeTips.
- A segment or two of vent pipe should be disconnected and removed.
- If you decide to handle it yourself, cut off the circuit at the service panel and check to be that the power has been turned off completely.
- If you require assistance with this project, contact a local water heater professional.
Installing a Tankless Water Heater
Tankless units can be fitted flush against the wall (against the drywall or plaster), or they can be inserted into the wall between the studs. Using a stud finder, identify the studs in the wall where you want to install the unit, and then cut a hole between each of them. Attach the item to the wall in accordance with the manufacturer’s recommendations. Water supply pipes should be routed to the water heater. Make certain that the pipe from the water utility is linked to the inlet and that the pipe flowing to the home is connected to the outlet before starting the project.
- You might also want to consider installing a pressure-relief valve.
- The water valves should be opened, but not those for the power or gas.
- Close the water valves and turn off the water.
- Replace the filter, turn on the water valves, turn on the electrical power, and turn on the gas valves if necessary.
Finally, test the equipment to ensure that it is in proper functioning condition. Resource Highlighted: Find a Pre-Screened Water Heater Pro in Your AreaCall today for free estimates from pre-screened water heater professionals in your area: 1-866-342-3263

What Is a Tankless Water Heater?
A tankless water heater is a more energy-efficient alternative to the typical tank-style water heater. When compared to traditional tank water heaters, tankless water heaters are more energy and cost efficient devices. What’s the difference between a tankless water heater and a typical water heating system? It is rather self-explanatory based on the name. A tankless water heater is a system that does not require the use of a tank to store water, as opposed to a traditional tank water heater. Tankless water heaters heat water on demand rather than conserving it for later use, resulting in hot water that appears to be available instantly.
Tankless water heaters are around the size of a suitcase in terms of size.
The Tankless Water Heater Installation Process
You’ve come to the correct site if you’re curious about how these heaters are placed. In order to give you a better understanding of what to expect, we’ve broken down the installation procedure. After we’ve removed your old water heater, there are a few procedures we need to do in order to correctly install your new water heater. First and foremost, we must choose the most secure location in which to install the tankless water heater. It is critical that we first check the water pressure in your home before proceeding with the rest of the procedure.
Following that, we will physically install the new heater by connecting it to the existing pipes in your home or business.

Last but not least, we will clean up any mess that we may have created and then leave you to enjoy your new water heater.
Is a Tankless Water Heater Right For You?
Tankless water heaters are a more cost-effective and energy-efficient way to heat the water in your house than traditional tank water heaters. Before purchasing or installing a tankless water heater, it is still vital to decide whether or not it is the best option for you and your needs. It is possible to save money on your water heater by using a tankless model if you have a smaller house and do not normally utilize the whole amount of water contained in a standard tank water heater.
Larger households, on the other hand, may not get the same benefits from a tankless water heater. Due to the increased workload, the water heater will be less efficient in providing adequate water for your household. Every month that you use a low-efficiency unit will cost you more money.
Benefits of Installing a Tankless Water Heater
The following are the primary advantages of installing a tankless water heater: Consider the following factors to evaluate if a tankless water heater is the best option for you.
Hot Water on Demand
You appear to have hot water on demand at all times due to the fact that water is delivered through the pipes and heated only when needed.
Reduced Utility Bills
Traditional water heaters maintain the temperature of the water even while it is not being used. This strategy will raise your energy usage, which will result in you spending more money every month as a result.
