What Does A Tankless Water Heater Cost

Tankless Water Heaters Cost Breakdown & Buyer’s Guide

Breaking a pipe, either from the hot pipe or from the cold pipe and resulting in a leak from a water tank can also generate running water sounds. Regular inspection and repair of damaged pipes delivering water to the water tank may prevent you from experiencing a water scarcity as a consequence of this leak, as well as from hearing the water heater’s running water make noise. We’d want to know what kind of noise you’re hearing from your water heater now that you’ve learned about the numerous issues that might cause a noisy water heater, as well as the methods for resolving them.

How much does a tankless water heater cost?

While tankless water heater prices can range anywhere from $170 to $2,000, on average, you should expect to pay something in the neighborhood of $1,000 dollars. In the case of small gas-fueled tankless water heaters, you may pay as little as $170, but for larger units that can deliver water to numerous appliances at the same time, you could pay as much as $2,000 or more. The type of fuel used in a tankless water heater has the greatest impact on the initial cost of the unit. As a general rule of thumb, gas-powered hot water systems are often two to three times more expensive than electric alternatives.

In order to purchase and install an entire home tankless water heater fueled by natural gas, you may expect to pay up to $3,000 in equipment and installation costs.

Electric units are normally around $600, while gas units are often around $1100.

In this post, you will learn more about your tankless water heater alternatives as well as how to compare them.

Factors that determine your tankless water heater cost

There are several elements that influence the overall cost of installing a tankless hot water system, including the type of fuel you use, the size of your equipment, and its overall condition.

Fuel type

A tankless hot water system can be powered by either natural gas or electricity, depending on your preferences. Typically, gas-powered units are two to three times more expensive than electric units, although the price difference can vary depending on a variety of other factors. Consider the price of gasoline as one element to consider. It is true that electricity is a slightly more expensive fuel for a tankless hot water heater when compared to natural gas, but it is also true that regardless of the fuel type that you choose, you will most likely pay a similar amount for fuel throughout the lifetime of the system because the differences in fuel costs are small.

With one additional wrinkle: it is projected that the price of natural gas would rise at a faster rate than the price of electricity, implying that electric units will only become more economically beneficial over the long term.

System size

It is also vital to take into consideration the system size, which relates to how much hot water can be produced by a certain tankless water heater and hence how much it will cost. In order to evaluate system sizes amongst on-demand water heaters, the easiest method to do so is to look at their gallon per minute rating, also known as GPM. In general, the greater the GPM, the higher the expense of your equipment will be to operate. Your required gallon per minute is determined by the number of appliances you need to operate at any particular time period.

For two bathrooms, the flow rate is 8-9 GPM, and for three or more bathrooms, the flow rate is 9-11 GPM.

GPM ratings for tankless water heaters are provided by the manufacturers and are generally found on the box, however this is a best-case scenario statistic that should not be taken out of context without further investigation.

Tankless Water Heater Costs by Size

Tankless water heaters are available in a range of sizes to ensure that a sufficient amount of water is delivered while maintaining the required temperature rise. gallons per minute is the unit of measurement for water volume rating (GPM). Depending on whether the model is based on combustion or electricity, the heating capacity is expressed in either British Thermal Units (BTU) or kilowatts (kW). Do not attempt to save money by purchasing a tankless water heater that is too small.

GPM

Calculate the total GPM of all water outlets that will be used at the same time to determine the appropriate tankless water heater size for your property. In order to take a shower while doing laundry and running the dishwasher, add the GMP for the shower (2-2.5), washing machine (2-2.5), and dishwasher (2-2.5) and divide the total by three (1.5-2). The GPM rate of a tankless water heater should be between 5.5 and 7.5, depending on the model. The flow rates for common household appliances are listed below on a typical basis.

  • Showerheads ranging from 2 to 3 GPM
  • Older or rain shower heads ranging from 4 to 6 GPM
  • Water faucets ranging from 1 to 2 GPM
  • Dishwashers ranging from 1.5 to 2 GPM
  • Washing machines ranging from 2 to 2.5 GPM

Temperature rise

The temperature increase is defined as the difference between the temperature of the entering water and the temperature at which you require the water to be. Tankless water heaters are rated based on the premise that the water is roughly 50 degrees Fahrenheit when it enters the system. For the majority of applications, water must be heated to around 115 degrees Fahrenheit. As a result, a temperature increase of 65 degrees is required (115 – 50 = 65). In cold or warm climates, the beginning temperature will be cooler or warmer, depending on the season.

With the GPM and temperature rise calculations, you may be confident in your selection of the appropriate unit.

  • 2 to 4 GPM range from $200 to $700
  • 5 to 7 GPM range from $425 to 900
  • 8-plus GPM range from $600 to $2500 or more

Tankless Water Heater Costs by Fueling Method

The typical cost of a tankless water heater varies depending on the kind of fuel used. The majority of users prefer either electric or natural gas (natural gas or propane). Models that are powered by electricity are the least expensive to acquire. Gas-powered units are slightly more expensive up front, but they are less expensive to operate on a monthly basis and have greater power. Consumers in areas where heating oil is common may find it to be a more cost-effective alternative. The use of solar energy may be preferable for those looking for an off-grid solution.

  • Electricity costs between $450 and $1,500
  • Natural gas or propane costs between $500 and $2,000
  • Oil costs between $600 and $3,000
  • And solar costs between $1,000 and $4,000

Average Tankless Water Heater Installation Cost

Electric water heaters are less difficult to install than gas water heaters. This is due to the fact that the latter requires release. In the event that you need to rewire your home or improve the electrical system in order to satisfy the amperage needs of your new electric water heater, this may be a different situation. In addition, it matters if you are only replacing an old heater, which means that most or even all of the plumbing connections and other components are already in place; if you plan to switch fuel sources; whether or not you need to make any modifications in order to meet plumbing or electrical codes; and whether or not you want to upgrade from a tank-based to an on-demand heater.

Aside from the fundamentals of labor, there are a number of other considerations:

  • The costs associated with equipment, components, and accessories (mounting hardware, pipes, valves, fittings, etc.)
  • And Cost of a permit – In most areas, permits are necessary for the installation of a new water heater. For further information, contact the municipality or city where you live. Warranty on labor for a specified period of time and within a specified scope

Hiring a Pro

Although it is hard to cover every conceivable case here, calling three or four firms in your region and asking for pricing estimates is generally the best course of action to take. Pro tip: Look for contractors who are licensed and insured, who have been in business for a number of years, and who provide a warranty on their work and materials. A service provider with an A+ rating on the Better Business Bureau website and other directories is also a solid sign of their reliability.

Yearly OperatingMaintenance Costs

Obviously, depending on the sort of tankless water heater you have, gas or electricity will be the primary source of your operational costs. In addition, the more hot water you use, the higher your utility expenses will be in the future. Which is more cost-effective: natural gas or electric power? As a general rule of thumb, a gas water heater will be around one-third less expensive to operate than an electric model, however this may vary depending on your local electricity costs. Another important consideration is temperature increase, which is dictated by the temperature of the input water as well as the temperature settings at the output.

It is possible, however, to change the thermostat on your water heater to the lowest output temperature that you are comfortable with.

PropaneNatural Gas Prizes

The cost of operating a gas tankless water heater ranges from less than $200 USD per year to more than $500 USD per year depending on the model. Only a tiny role is played by the efficiency of the system. Natural gas is the least priced choice because it is powered by a utility supply line. In contrast, propane is a more efficient fuel with a significantly greater BTU, but it must be purchased separately from the rest of the fuel. Prices for natural gas and propane vary depending on where you live.

Electricity

Gas tankless water heaters have annual operating costs ranging from less than $200 USD to more than $500 USD. Efficacy of the system is simply a secondary consideration. Natural gas, which is supplied by a public utility distribution system, is the more affordable alternative for powering equipment.

For its part, propane, which has significantly more BTU, is the most efficient fuel; nevertheless, it must be purchased separately. Natural gas and propane costs differ from one region to the next depending on where you live.

Tankless Water Heater Maintenance Cost

When it comes to maintaining a tankless unit, all that is required is periodic descaling (also known as deliming) and flushing of the heating components to keep it operating at optimal performance. This is normally required once every 12 months, depending on the hardness of your water and how much water you consume. As a point of reference, if you have a water softener placed upstream of your instant hot water heater, you won’t have to bother about descaling. Furthermore, the methods needed are not extremely hard, so you may complete this task on your own to save a few dollars.

It takes 1 to 2 hours for a plumber to do routine maintenance.

Are Tankless Water Heaters Worth the Investment?

As previously stated in the introduction, a tankless water heater is a more expensive upfront expenditure when compared to a typical water heater. However, it reduces recurring expenses by a significant margin since it has virtually no standby losses – in contrast to storage tank systems, which heat water around the clock. According to the United States Department of Energy, on-demand water heaters can be up to 30 percent more energy efficient than traditional water heaters, depending on how much hot water you consume on a daily basis.

Are they worth the money?

Average Cost Savings

As previously stated in the introduction, a tankless water heater is a more expensive initial investment than a typical water heater. In contrast to storage tank systems, which must heat water around the clock, it reduces recurrent expenses by a significant margin because it has essentially no standby losses. According to the United States Department of Energy, depending on how much hot water you use on a daily basis, on-demand water heaters can save you up to 30% on your energy bills. But the issue remains: Are tankless water heaters a good investment?

Tankless Water Heaters – Pros and Cons

What are the advantages and disadvantages of putting up a tankless water heater in your home?

Benefits

The following are some of the advantages of tankless water heaters:

  1. When compared to standard water heaters, they are more energy efficient than those. This is due to the fact that they do not hold any hot water, therefore eliminating standby losses. The heating takes place instantly, allowing you to save up to 30% on energy costs. Heating water on demand also ensures that you will never run out of hot water. Tankless water heaters provide an infinite supply of hot water since they are tiny and therefore easier to install in confined spaces. Having a new water heater will also free up room in your basement or wherever you decide to install it. They are simple to prepare for the next winter season. As previously said, a tankless water heater may last up to 20 years, but a standard water heater with a tank can only last 15 years.

Disadvantages

The following are some of the disadvantages of tankless water heaters:

  1. Both the purchase and the installation are more expensive in the beginning. As a result, the payback period is lengthy
  2. Tankless water heaters are susceptible to sluggish flow
  3. Electric tankless systems are restricted in terms of the amount of hot water they can produce at any given moment. However, even the largest units designed for residential usage are unable to heat more than 6 gallons per minute under optimum conditions.

Where to Buy a Tankless Hot Water Heater

Where is the most convenient location to purchase a new tankless water heater? Of course, we always prefer to shop online, for example at Amazon or Home Depot, in order to get the greatest deal possible. However, most manufacturers also sell their hot water heaters through local dealers and/or licensed contractors, which is a common practice in the industry. Home improvement stores and big-box retailers are another feasible choice.

A Tankless Job? Decide Whether a Tankless Water Heater Works for Your Home

Stiebel-Eltron, a German business, invented the world’s first electric tankless water heater over 100 years ago today. Despite the availability of an alternative solution, classic water heaters with storage tanks have remained the most popular choice. Tankless designs, on the other hand, have gained in prominence in recent years. This Might Also Be of Interest to You: Listed below is an estimate of the cost to replace a water heater. If you are thinking about replacing your present water heater with a tankless unit, the cost is most certainly your primary consideration.

Is it worth it to pay the extra money?

Why Go With a Tankless Water Heater?

In the casing of a tankless water heater, there are networks of coils that heat the water as soon as it is turned on at the tap or in the shower. They employ heat exchangers to turn energy into practically instantaneous hot water, whether they are powered by gas or electricity. Tankless water heaters do have certain advantages over traditional types that rely on holding water in a reservoir, as previously stated. Compared to tankless solutions, tank-based systems demand much more floor area. In addition to the space required for the tank itself, most building and construction rules stipulate that water heaters must have a minimum of 12 inches of clearance on all sides before they may be installed.

Tankless models, on the other hand, are often mounted to the wall, which allows for more useable area to be created.

Gas and electric tankless alternatives may either be vented up and out, or the surplus heat can be expelled through the sidewalls of your home, depending on your preference.

Gas Vs. Electric Water Heaters: Which is Better?

Water heaters that are electric or hybrid are the most energy-efficient solutions available on the market today. These models have minimum efficiency ratings of 90 percent, while certain hybrid versions that make use of solar technology can achieve efficiency ratings of 95 percent or more. Gas water heaters, on the other hand, often have an efficiency rating ranging between 67 and 80 percent, depending on the model. However, because natural gas is substantially less expensive than electricity, these water heaters can be significantly less expensive to operate when compared to an electric counterpart.

According to the National Water Heater Association, an electric water heater will cost roughly $285 per year, while a gas water heater would cost approximately $110 per year – depending on your energy expenses.

Choosing Between Condensing and Non-Condensing Types of Water Heaters

There are two types of gas or electric water heaters: non-condensing and condensing. Non-condensing water heaters are less efficient than condensing water heaters. Traditionally installed water heaters are non-condensing, which means that once the gas is consumed to heat the water, any extra heat is vented to the exterior of the home. These water heaters typically have an efficiency rating of 80 percent or more at their highest capacity. Many of the most recent tank and tankless gas alternatives are condensing water heaters, which are energy efficient.

These models have minimal heat loss and can reach energy efficiency ratings of 90 percent or more than the industry standard.

Should You Consider Point-of-Use Water Heaters?

Some people have expressed frustration with tank-based water heaters, claiming that they need a long period of time before the water is heated enough to use for dishwashing or taking a shower. The amount of time required varies based on how far away the faucet is from the water heater is located. Many tankless water heater manufacturers promote their products as giving virtually limitless hot water on demand. Despite the fact that these types frequently provide hot water more rapidly, they still need heating the water as it enters your home.

  1. These point-of-use devices may be installed immediately in the room where you want hot water.
  2. Each type has its own heating element, which can quickly heat water to a desired temperature.
  3. If you use a point-of-use water heater for each shower or faucet, you may save up to 50% on your energy bills when compared to using a whole-home water heater, according to Energy.gov.
  4. First and foremost, point-of-use models must be smaller in order to fit under a sink or next to a shower.
  5. Furthermore, there is no system in place to accommodate increased demand.

How to Find the Right Hot Water Heater Capacity

Traditional water heaters are often equipped with a tank that holds at least 50 gallons of hot water. Larger residences, on the other hand, will have tanks with capacities ranging from 80 to 100 gallons. The tank is used to store hot water so that it is available when you want it. This additional capacity will allow you to operate the dishwasher and the washing machine simultaneously while someone else showers. Tankless water heaters, on the other hand, do not have a storage mechanism. The majority of tankless devices have a capacity of two to twelve gallons of water per minute.

An HVAC professional should be consulted in order to guarantee that your tankless system is properly sized. To give you an idea of how much hot water is required by popular fixtures and appliances, here’s a rough estimate:

  • Showerhead flow rates range from 2 to 3 gallons per minute
  • Washing machine flow rates range from 2 to 2.5 gallons per minute
  • And faucet flow rates range from 1 to 2 gallons per minute.

Things to Know About Tankless Water Heater Costs

Tankless water heaters are connected with a number of extra expenditures in addition to the purchase price of the system itself. It is possible that specialized pipes and connections may be required, which will increase the overall cost. You will also require the services of a qualified HVAC professional to assess your home and establish the minimum flow rates required depending on the number of bathrooms, sinks, and anticipated water use. Comparing tankless water heaters to tank-based water heaters, tankless water heaters feature more complicated connections, regulators, and other critical components.

Water heaters that run on natural gas are also more complicated to install since they require specific three-quarter-inch pipe to ensure that they have adequate natural gas supply to meet the demands of your home’s hot water needs.

Water heaters that run on electricity normally require at least 120 amps to work efficiently.

If you intend to install an electric tankless system, you may need to hire an electrician to run larger energy lines and construct a new electrical panel in order to complete the installation.

Is It Worth It?

So, is a tankless water heater preferable to a conventional tank-based system in this instance? It all boils down to how much money you’re willing to put out as a down payment. Tankless versions have the potential to be substantially more energy efficient than their predecessors. It is possible to get virtually immediate hot water if you install many POU units around your home. As an added bonus, tankless water heaters have a service life of up to 20 years when used continuously, which is more than double the estimated service life of a tank-based water heater.

Tankless designs are frequently more complicated and have a greater number of connections, regulators, and components than traditional water-storage systems.
