- 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
It costs around $1,000 to $1,500 to build a natural gas or propane fireplace. These two types of gas will both feed your system in the same manner, but the costs of purchase and operation are significantly different. In contrast to natural gas, propane must be purchased separately and is dependent on a utility supply line. If you reside within a particular distance of a natural gas line, you may be forced to connect to it to keep your home running. This isn’t an issue for the majority of people who own their own homes.
In contrast to natural gas, propane is a more environmentally friendly and energy-efficient fuel that produces more BTUs.
Also available in residential and commercial grades, they have a variety of outputs ranging from 140,000 BTUs to 380,000 BTUs.
- 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.

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?

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. When you turn off the hot water faucet, the machine detects that the flow of water has ceased and automatically turns off the heating element.
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
- They are more compact than typical storage heaters, are wall-mounted, and do not take up any floor space when in operation. When it comes to homes where square footage is limited, their size may make them particularly appealing
- They can also assist you in lowering your energy expenditures. Energy expenses for heating water account for around 30% of a family’s total energy bills, according to the United States Department of Energy. It is possible to save up to 50% on these expenditures by installing a tankless water heater, resulting in an annual savings of around $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 water heaters have a lifespan that is about twice as long – 20 years or longer.
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.
It is particularly stated that AHS takes no responsibility, and expressly disclaims all liability, in connection with your use of any and all material included on this website.
WE HAVE OPTIONS BECAUSE WE CARE.
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.
Then there are the niggling concerns such as: Is it clogged with silt that consumes energy? Is there a chance of a leak? Both of these worries are fair given the fact that tanks often fail between 8 and 12 years.
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?
A tankless water heater has several advantages, and these are the arguments in favor of purchasing one. The heater only provides hot water when you need it and just for the amount of time you need it, saving you 27 to 50% on fuel expenditures as compared to tank-type heaters. (A typical gas-fired tank loses 40 to 50% of the fuel it burns, according to industry standards.) Furthermore, because there is no tank to fail, there is essentially little likelihood of a catastrophic leak occurring in this configuration.

- 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.
How Long Do Tankless Water Heaters Last?
It is expected that gas-burning tankless water heaters would last 20 years or longer, which is two to three times longer than tank-type heaters. Tankless electric units have shorter life lifetimes, ranging from 7 to 10 years, compared to conventional units.
Where Can I Buy One?
They may be found at plumbing supply stores, big-box stores, and internet sellers, among other places. Alternatively, you may order one via your plumber.
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:
Thanks to Noritz for providing this image. The advancement of tankless technology is ongoing. A few of the most recent improvements are as follows:
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.

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:
Doug Adams has created this illustration. You and your plumber must evaluate the following items before to the installation date:
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.

- 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.

This is not going to be free, so be prepared! The time it takes for a plumber to come out to your house is considerable, and they frequently need to do some diagnostics before providing you with an estimate.

How Much Does It Cost to Install a Tankless System Yourself?
While it is possible to install a tankless water heater yourself, you must have prior knowledge in order to save money and do so in a safe and efficient manner. It is strongly recommended that you should not attempt to accomplish this job on your own. This might result in significant harm or property damage to you or your loved ones. An inexperienced handyperson may cause an explosion or discharge carbon monoxide into the air if a tankless water heater is installed or repaired. Not to mention that if a system is not installed by a professional, many warranties will be worthless, and your house will be at a higher risk of not being up to code if you ever decide to sell your property.
How Much Does It Cost to Install a Tankless Water Heater by Type?
Are you curious about how much money you can save (or spend!) by switching to a tankless water heater?
One of the most accurate ways to estimate your costs is to consider the type of heater you pick. There are four different types of tankless heaters to take into consideration:
1. Electric Tankless Water Heaters
Installing an electric model is the most economical alternative, with costs typically ranging between $800 and $1,500. Keep in mind that, unlike other more expensive solutions, you will not be required to spend additional funds on ventilation systems or upkeep.
2. Natural Gas Tankless Water Heaters
Installing an electric model is the most economical alternative, with costs ranging between $800 and $1,500 on average. Keep in mind that, unlike other more expensive solutions, you will not be required to spend additional money on ventilation systems or upkeep.
3. Propane Tankless Water Heaters
Although propane water heaters are the same price as natural gas water heaters for installation ($1,000 to $1,500), the cost of the fuel itself may add up, with propane costing approximately$350 per year to operate.
4. Solar Tankless Water Heaters
Solar heaters are the most expensive choice, with prices ranging from $1,800 to $6,000, though some may cost more than $13,000. Keep in mind that solar water heaters provide a larger return because they qualify for a 30% tax credit as well as a 50 percent to 80 percent reduction in your water heating bills due to the 30 percent tax credit.
What Factors Influence the Cost of a Tankless Water Heater?
Adobe Stock / Wavebreak3 / Wavebreak3 The cost of a typical tankless water heater is influenced by a variety of factors, including:
- Kind: The type of tankless water heater you choose has an impact on the cost, with electric being the most economical option, followed by gas and finally solar, in that order. These expenses range from $800 to $6,000, depending on the situation. The cost of a single point or whole-house point system can range from as low as $100 to as much as $6,000, depending on the size of the system you pick. Number of heaters: If you are purchasing a single-point tankless water heater, you may find yourself having to purchase numerous heaters to fit different rooms. These heaters are typically priced between $100 to $300 per unit. Quality: You get what you pay for
- If you want to use the heater on a regular basis, it is worthwhile to invest a little extra money on a higher-quality model. Expect to pay $1,000–$3,000 more for a high-quality tankless water heater than you would for a lower-quality tankless water heater. On-site issues: If you have a bathroom that is too tiny for a plumber and a helper to work side by side, your installation expenses may increase. Expertise of the installer: An experienced HVAC expert or plumber and his or her assistant will do the task fast, but they will charge more than a handyman service.
Tankless water heaters are installed by plumbers and HVAC specialists in your neighborhood. The cost of labor will range from $40 to $175 per hour for your project. Local supply and demand, as well as any discounts or offers offered by a contractor or plumber, all have an impact on how much you will pay for services. Removal and installation of a typical tankless water heater, with no hidden issues, takes around three hours. As a result, total labor rates to remove an old water heater and install a new tankless system might range from $120 to $525.
Hidden Costs to Consider
When calculating the price of a tankless water heater, remember to include any hidden costs associated with the equipment, installation, and use. Example: If you require accessories to connect the tankless water heater to your plumbing system, the cost of the equipment may increase. If your home’s water pressure is inadequate, one regular and unexpected expense is the cost of adapting it. If your house pressure is low, a plumber may be required to repair a pressure regulator, clean clogged pipes, or install a bigger pressure tank (if you are on a well) in order to restore proper pressure.
This also helps to avoid disappointment if you anticipate that the tankless heater would save you a significant amount of money on fuel expenditures, which it will not.

Tankless vs. traditional
Understand the differences between tankless and regular water heaters may be easier if you look at this chart. A typical water heater warms and stores water in a tank with a capacity of 30 to 50 gallons, depending on the manufacturer. The heated water remains in the tank until it is required, and when it is consumed, the tank is refilled and the preheating process is repeated. A tankless water heater heats water on demand by using either electricity or natural gas as a fuel source. As a result, as soon as you switch on the dishwasher or step into the shower, the water that is required is heated at the source and is instantly available for use.

- There is a one-time fee. For $500-$700, you can have an electric model, while for $1,000-$1,200, you can get a gas model. Cost of installation: The cost of installing the device and upgrading utility hookups is between $1,000 and $2,000, depending on local expenses and the amount of work that has to be done. Gas versions require the installation of a safe ventilation system, whereas electric ones do not, making the installation of gas models more expensive. Cost of utilities: Gas may be less expensive to run than electricity depending on the cost of utilities in your location.

An electric tankless water heater has no negative influence on the environment since it emits no greenhouse gases and is easy to recycle at the end of its useful life.
Benefits of a tankless water heater
A tankless water heater consumes 30 to 50 percent less energy than a traditional water heater, resulting in annual savings of more than $100 for the average household on heating bills. Instead of wasting 30 percent of its energy, a tankless water heater wastes just 5 percent, according to Energy Star. Although you may have to wait a few seconds for the water to heat up at the source, a tankless water heater ensures that you will never run out of hot water in your home. A tankless water heater is more compact and takes up less space than a standard water heater.
Lastly, a standard water heater has an average lifespan of eight to ten years, but the average lifespan of a tankless water heater is closer to twenty years.
Disadvantages of a tankless water heater
It is more expensive to purchase and install a tankless water heater upfront than it is to purchase and install a regular water heater. In fact, depending on the unit and the amount of retrofitting your home required, it might cost up to twice as much as a standard unit. It might take up to ten hours to complete the installation due to the level of skill required. The time it takes for hot water to be heated and supplied is longer. You may encounter what is known as a “cold water sandwich,” which occurs when the hot water is switched on but does not have enough time to heat up properly.
The final word
It is possible to use a tankless water heater when rebuilding your house or building a new one, or while staying at home on a part-time basis and do not want to be concerned about a leaky hot water heater while you are gone. Unless you have professional-level installation abilities, installing a tankless water heater is not a do-it-yourself effort. Despite the fact that they can be purchased online or at your local home improvement shop, it is better to leave installation to the professionals because it may be necessary to adapt your home in order for the water heater to function effectively.
It is possible that a tankless water heater will be less expensive in the long term when yearly energy savings and the fact that you will only have to replace it half as frequently as a standard unit are taken into consideration.
