Tank vs.Tankless Water Heater Costs |Gas vs.Electric Water Heater Costs |Energy-Efficient Water Heaters |

Signs of a Failing Water Heater |Choosing Your Water Heater |When to Call a Plumber |

Frequently Asked Questions |In practically every family, having access to clean, hot water has become a luxury.While the requirement for hot water in a home is constant, the methods by which it is produced are constantly evolving, with a wide range of tanks and fuel sources accessible to homeowners.If you’re buying a water heater for the first time or replacing an old one, it’s crucial to understand the different types of water heaters available and how much each one costs.

Tank vs. Tankless Water Heater Costs

In terms of water heaters, the tank and tankless water heaters are two of the most popular options available.

Tank Water Heaters

Storage tank water heaters are a popular alternative for households because they can keep and heat large amounts of water on a continuous basis.Water heaters are often situated out of sight, in a garage, basement, or utility closet, among other places.Tank water heaters generally utilize electricity or natural gas to heat the water they produce.The installation of a storage tank water heater is less difficult than the installation of a tankless water heater, needing just roughly three hours of effort.The storage tank water heater is a traditional water heater that is simple to install.

Storage tank water heaters are less expensive than tankless systems, with prices ranging from $820 to $1,290.Tank heaters, although being a more inexpensive choice, are less energy-efficient due to the fact that they must operate continuously in order to maintain the target tank temperature.In turn, these tanks have higher utility costs and a shorter lifespan as a result of their design.

Tankless Water Heaters

Tankless water heaters function by heating water only when it is required.The technology heats the water pipe with either a gas burner or electricity, allowing it to furnish water on demand.A tankless device, like a hot water storage tank, can be kept in a basement or utility closet for easy access.Tankless heaters are less bulky than tank units and may be placed on the wall of a bathroom or bedroom, for example.Tankless water heaters have a greater initial cost than tank water heaters, with prices ranging from $1,200 to $3,500 for a typical home.

The increased cost is due to the more labor-intensive set-up necessary for the installation, which necessitates the construction of additional gas and water lines.Electric tankless heaters will require the installation of brand new electrical wiring.Even while tankless heaters are more expensive to install than traditional versions, they are more energy efficient and have a cheaper total cost of ownership than their counterparts in most cases.

Furthermore, these water heaters have a longer longevity, with an average lifespan of around 20 years.

Gas vs. Electric Water Heater Costs

Tankless and tank water heaters are both available in gas and electric variants, with each offering its own set of advantages and disadvantages to homes.

Electric Water Heaters

In comparison to a gas tank, an electric tank is less expensive to purchase and install, with a home 50-gallon tank water heater costing approximately $500.The overall cost of operation on a monthly basis, on the other hand, is typically more than the cost of operating a gas heater.Because there is a lower danger of a leak or combustion with this heat source than with gas, it is regarded to be safer than gas.The disadvantage of using an electric heater, which is more ecologically friendly, is that if the power goes out, so does the hot water.

Gas Water Heaters

Gas heaters are more expensive to acquire, with a 50-gallon tank costing around $700.The operating costs of these heaters, on the other hand, are less expensive than those of an electric type.Despite the fact that natural gas is more likely to combust or leak, a gas-powered water heater produces hot water without the use of electricity.The most significant disadvantage of using a gas water heater is the harm it causes to the environment via the release of carbon dioxide.More information may be found at A Guide to the Best Water Heater Warranty.

Energy-Efficient Storage Tank Water Heater Costs

If you want to be more ecologically concerned, you might consider purchasing one of these energy-efficient water heaters instead.

Solar Water Tank Heaters

Natural sunlight is used to heat the water in these water heaters.A solar water heater system is made up of two parts: a storage tank that retains water and solar collectors that produce heat.In most cases, a solar water heater will rely on a standard water tank in the event of a power failure.Active solar water tank systems and passive solar water tank systems are the two main types of solar water tank systems.An active system provides water to residences through the use of a pump, whereas a passive system circulates water around the home through the use of natural convection.

A passive system will cost roughly $2,000, while an active system will cost around $3,000, according to the National Association of Home Builders.The increased expense is due to the considerable amount of labor required as well as the requirement for a backup water heater.

Indirect Water Heaters

Heat is provided to the tank by an existing furnace or boiler, which is powered by the energy from the furnace or boiler.The water from the boiler is cycled into the tank’s coils, where it is heated by the water contained within.This water heater style is energy efficient, as it relies on heat generated by a boiler or furnace to heat the water.Although the monthly cost of an indirect water heater is cheap, the initial purchase and installation costs are higher than those of standard heaters, with the cost of an indirect water heater ranging from $1,500 to $2,000.

For example, if you’re considering a natural gas water heater, ensure sure your home already has or is capable of receiving a natural gas connection before proceeding.
  • Household size and number of people in your home should be taken into consideration when purchasing a gas tank of the appropriate size. For example, a family of two people need a 30–40 gallon tank, but a household of four people requires a 50–60 gallon tank.
  • Savings on both costs and energy—
  • Consider the price of each water heater as well as the cost of the fuel it uses. However, while certain heaters may be more expensive up front, their energy efficiency may allow you to save money in the long term.

When You Should Call a Plumbing Professional

It is suggested that you contact a professional if your water heater is showing symptoms of wear or if it has abruptly failed. While you may opt to replace a water heater as one of your home improvement projects, the amount of effort required and the extensive expertise required to install a system make water heater repairs and replacement a job best suited for a plumbing professional.

For an electric water heater of the same size, the cost is around $1,000, while a natural gas water heater of the same capacity is approximately $1,200. Send an email to our Reviews Team at if you have any comments or questions about this post.

How to Install an Instant Hot Water Heater

The most common types of house water heaters are the massive storage models that take up a substantial amount of space in the garage or basement.Some households are opting to install instantaneous, or tankless, hot water heaters as a more energy efficient option.These extraordinarily compact devices heat water on demand, eliminating the need for people to wait for hot water to reach a specific tap.When installing an instant hot water heater, it is important to pay close attention to the plumbing and electrical connections in order to guarantee that the device functions properly.

  1. Determine the location of the new hot water heater. It is possible to put the little gadget below a sink on a wall where the hot and cold water supply pipes are easily accessible. Make sure there is at least 12 inches of clear space around the outside of the heater
  2. Place the hot water heater against the wall that you want to use. Using a screwdriver, insert four screws into the device’s associated mounting brackets and into the wall to secure the gadget. Place each screw in one of the heater’s four corners on the outside of the heater’s assembly. Pulling on the heater’s exterior assembly will help to ensure that it is tightly against the wall.
  3. By hand-turning the valve, you may switch off the water supply to the sink next to it. Check the water knobs on the sink to ensure that the water supply has been turned off.
  4. Tube cutters should be used to cut the cold water supply pipe close to where the heater will be installed. To remove a portion of tubing for the Y-future fitting’s installation, cut the same line with the tube cutters a second time around 1 inch below the initial cut region.
  5. In the cut section of the cold water supply line, install a Y-fitting to keep the water flowing. A bucket should be placed beneath the Y-fitting so that it may be soldered to the line with a soldering iron. Turn on the water valve if it is not already on. Allow the cold water to circulate through the system and into the bucket for a few minutes. It is used to remove debris and scale from the immediate pipe region, as well as to ensure that the Y-fitting was correctly placed.
  6. Reverse the flow of water at the shutoff valve. Remove the bucket from the table
  7. Solder the ball valve to the open Y-fitting with a soldering iron.
  8. Steps 4 and 5 should be repeated for the hot water supply line.
  9. The hot water line’s Y-fitting should be pushed onto a flexible water hose, and the other end of the hose should be connected by hand to the heater’s ″hot water out″ connection point. To securely attach the hose’s fittings to both connecting locations, employ a compression tool.
  10. Step 10 should be repeated for the cold water line. Connect the hose from the ball valve to the ″cold water in″ connecting point
  11. turn on the water at the ball valve to begin the process. Make sure that the taps are turned on at the knobs and that both hot and cold water are flowing through the new water heater. Check for leaks at the plumbing connection points to ensure that there are none. After the water has been running for approximately 3 minutes, turn off the faucets.
  12. Turn off the circuit breaker at the main electrical panel, which will be linked to the heater in a few minutes time. Using a non-contact circuit tester, confirm that the power has been turned off.
  13. Connect the electrical cables that run from the heater to the electrical distribution panel. If you need special wiring instructions, see your owner’s handbook. Depending on the manufacturer, each wiring layout is different.
  14. Check to see that the hot water heater is working properly by turning on the circuit breaker and running it for a few minutes.

Are Instant Hot Water Systems Worth It?

It should come as no surprise that there are instant hot water systems in a society where everything is automated or available immediately.A continuous flow water heater (also known as a tankless water heater) provides you with nearly limitless hot water, and you only pay for the water that you really use.Furthermore, there is no longer any need for those unsightly, oversized storage tanks!Instant hot water is provided through a tankless device that is installed on the wall.It is estimated that an electric instant hot water system costs more than twice as much to operate as a gas instant hot water system, according to the Australian Energy Foundation.

All of this appears to be too wonderful to be true.There’s a good chance you’re thinking there’s a catch somewhere in there.Metropolitan Plumbing has over 25 years of expertise in the field of hot water, and we’re here to tell you whether or not instant hot water is actually worth the money.

As your hot water specialists, we’ll walk you through the advantages and disadvantages of instantaneous water heating systems.

How Do Instant Hot Water Systems Work?

The most significant advantage of instant hot water is that it only heats water when it is required.In contrast to a storage tank water heater, which heats and stores water until it is needed, this one just heats and uses the water as needed.The entire tank is heated, regardless of whether or not it is in use at any one time.The majority of fast water heaters operate on natural gas as their energy source, however electric models are available as well.An automatic flow sensor is activated when you switch on the hot water faucet.

This initiates the ignition of a gas burner or an electric element.The water is heated in a serpentine-shaped copper tube that is wrapped around a heat exchanger in this system.The hot water is pushed out of the tank and given to the faucet.

When it comes to heating, cold water takes the role of hot water.Whenever the hot water tap is turned on, the water is constantly heated up.In addition, when it is turned off, the heating element/burner is switched off as well.Generally speaking, natural gas is a more cost-effective and energy-efficient energy source than other types of electricity.

  • When natural gas is not accessible, however, electric instant hot water can be used as an alternate source of heat.

What Size Do I Need?

  • Instant hot water systems, in contrast to standard water heaters, do not require a tank! There isn’t a certain size available that will meet the requirements of your home. As an alternative, you should seek for a flow rate that would fulfill your water consumption needs. The flow rate is the amount of water in litres per minute that the system is capable of heating and delivering. Flow rates of 10 to 32 litres per minute are normal for this type of pump. When determining the flow rate for your home, you must consider more than simply the number of bathrooms and persons in the house. There are a few of important things you should keep in mind: How many individuals are in the shower at the same time? Do you run your dishwasher or washing machine with hot water?
  • Are there individuals in the shower while the dishwasher or washing machine is being used?
  • Are there water-saving shower heads fitted in the showers?

It is critical that you select the appropriate flow rate in order to avoid spending more money up front than you need to.It may also result in a higher overall operating expense.Another advantage of instant hot water systems is their compact size, which is due to the fact that they are tankless and wall-mounted.This also makes these systems an excellent choice for households with limited outside area, as well as for condominiums and flats.

Is it Safe?

Yes!Instantaneous hot water systems, on the other hand, are arguably safer than storage tank water heaters.There is always the possibility of germs forming in stored water.As a result, the thermostat for hot water systems is always set at 60 degrees Celsius or higher.Legionella bacteria, for example, may proliferate in water sources and cause Legionnaires’ illness and Pontiac fever in people who are exposed to them.

In 60°C water, 90 percent of Legionella bacteria die in 2 minutes.All Legionella die nearly rapidly when exposed to water temperatures more than 70°C.Thermostats can become malfunctioning or be accidently knocked without the user realizing what has taken place.

If this happens, your storage tank is at risk of becoming a breeding ground for harmful bacterium.Corrosion will occur in storage tanks as well over time.When this occurs, you may see rust stains in your drinking water as a result.Instant hot water systems do not hold water in the first place, therefore there is no possibility of hazardous germs or rusty water forming in them.

  • In addition, because you don’t have to boil the water as much, the danger of burns from overheated water is significantly decreased.
  • In reality, Australian requirements mandate that storage tanks be equipped with a tempering valve, which restricts the temperature of water delivered to fixtures used for personal hygiene to no more than 50 degrees Celsius.
  • These valves combine your cold water supply with the 60°C water from the storage tank in an effort to reduce the risk of scalds.
  • Instant hot water systems, on the other hand, eliminate the need for this valve because the thermostat of these systems may be adjusted immediately to 50 degrees!

How Long Do Instant Hot Water Systems Last?

With adequate maintenance, a typical storage tank hot water system may last between 8 and 12 years, depending on the manufacturer.In our research, we discovered that instant hot water systems had a longer lifespan than their storage tank equivalents.It is fairly unusual for them to endure for upwards of 20 years!Regular maintenance and service of your water heater is required in order to get the most out of it and guarantee that it is operating properly.This will not only help to extend the life of your instant hot water system, but it will also prevent you from wasting water and energy in areas where it is not necessary.

Does Instant Hot Water Save Money?

Long-term savings are achieved by installing an instant hot water system correctly.While they are more expensive up front, you will save money in the long run since you will only be charged for the hot water you consume.Not only that, but you won’t have to be concerned about heat loss from a storage tank.On average, we’ve discovered that instant hot water systems outlast storage tanks and even certain electric water heaters.Instant hot water, when combined with the absence of sacrificial anodes that must be changed on a regular basis, as is the case with storage tanks, is guaranteed to make your wallet happy.

Not only will you save on energy costs for your hot water, but you will also reduce your carbon dioxide gas emissions as a result of your actions.The installation of an instant hot water system will help both you and the environment.

What are the Downsides of Instant Hot Water?

How come instant hot water systems aren’t installed in every single home if they’re so effective?The advantages of having immediate hot water outweigh the disadvantages, which include the following: Despite the label ″instant″ hot water, you will not truly receive hot water immediately after turning on the faucet.There is a delay between turning on the faucet and the water reaching the temperature that has been preset.Although it won’t take long, you may notice some additional water waste while you’re waiting for the heat to come on.It is necessary to have a particular volume of water running through the hot water tap in order for it to be heated.

It is possible that a combination of low-flow showerheads and a trigger flow rate that is set too high can result in your shower not activating water heating!By hiring a competent plumber and advising them of any fixtures that may interfere with the plumbing, you may simply prevent this situation altogether.Another issue to consider with instant hot water is that the flow rate may not be sufficient to suit the needs of a large household.

It is possible that you will encounter low water pressure if the demand for hot water exceeds the capacity of the instant water heater.This is merely due to the fact that the hot water is being sparsely distributed in an effort to provide hot water to everyone.This may be avoided by scheduling hot water use so that demand does not exceed the flow rate production.A storage tank hot water system may be a preferable option for households with recalcitrant family members who refuse to compromise on their shower time.

Water heater replacement: pros and cons of tankless water heaters

Tankless water heaters, also known as on-demand water heaters, are becoming increasingly popular among environmentally conscious households, and for good cause.A tankless water heater does not have a tank (thank you for asking).While a traditional tank water heater slowly heats water in a tank and maintains the temperature of that hot water, a tankless water heater only heats the water that is really needed, and it does it extremely rapidly.The vast majority of tankless water heaters on the market today are high-efficiency, direct-vent, powervent devices using powervent technology.In addition, whereas traditional tank water heaters are all relatively similar in appearance, the same cannot be said with tankless water heaters, which are more diverse in appearance.

Because they are all so distinct, I have to talk in broad strokes for the sake of this blog article.

Benefits of a tankless water heater

The fact that a tankless water heater is smaller than a traditional water heater is an apparent advantage.In order to avoid taking up a large amount of floor area, tankless water heaters are typically installed on a wall.Another significant advantage is the virtually limitless supply of hot water.Shower for five hours and never run out of hot water is a reality for many people.For those who have access to a hot tub, you could fill the entire thing with hot water and be ready to utilize it as soon as the water is through filling it.

The fact that tankless water heaters use less energy is, without a doubt, their most significant advantage.Tankless water heaters do not face the same standby energy losses as typical tank water heaters since there is no tank of heated water that needs to be maintained at a constant temperature all of the time.How much less do you want?

According to my research, the most energy-efficient gas tankless water heater was a Bosch Greentherm 9900 series unit, which had an energy factor of 1.Natural gas consumption for this water heater is estimated to be 150 therms per year, according to the Energy Star website.The majority of typical tank-style water heaters have an energy factor of about.67 and consume approximately 225 therms each year.Natural gas is now priced at around 52 cents per therm in Minnesota.

  • At today’s petrol costs, that translates to a savings of approximately $40 per year.
  • Tankless water heaters also have a longer lifespan, with heat exchanger warranties often ranging from 12 to 15 years in length.
  • In most cases, a 6-year guarantee is provided with Powervent water heaters, but classic tank water heaters are often covered by warranties of 6, 9, or 12 years.

Drawbacks to tankless water heaters

The most obvious disadvantage of a tankless water heater is the greater expense of the device itself as well as the labor to install it.Tankless water heaters are more expensive than standard tank water heaters; usually, the unit alone costs around twice as much as the tank water heater, depending on the flow rate required.As a result of the greater BTU rating, they are also more difficult to install due to the particular venting requirements and the fact that they require bigger gas lines than other models.It goes without saying that this will result in a greater cost for installation.Despite the fact that tankless water heaters can produce a limitless quantity of hot water, there is a limit to the volume of water that can be delivered at one time.

Conventional water heaters have the capability of delivering as much hot water as the pipes will allow in one continuous flow.Tankless water heaters, on the other hand, require the water to be heated as it goes through the heater when it is being used.It is critical to get a tankless water heater that is large enough to ensure that there is an appropriate supply of hot water.

Smaller tankless water heaters are only capable of delivering enough hot water for one shower at a time in colder areas like ours, where the groundwater is significantly cooler.As long as a sufficiently big water heater is installed, there should be no problems.Tankless water heaters require more time to heat water than traditional water heaters.Hot water is stored at the top of the tank in traditional water heaters, ready to be used when the tank is full.

  • When using a tankless device, cold water enters the heat exchanger tubing and immediately begins to heat.
  • All of the water that has accumulated in the tubing since the unit was last fired will be delivered to the fixture first, before any new water can be added.
  • As a result, tankless water heaters take longer to heat up and provide hot water.
  • Installation of a small tank water heater after the tankless water heater to serve as a tempering tank is one solution to the long wait time.
  • However, this does not qualify as a true tankless system after this is accomplished.

On-demand hybrid water heaters, such as the Rinnai hybrid unit seen to the right, are also available.However, this is no longer a tankless water heater, as previously stated.Another option is to construct a circulation system to ensure that hot water is always accessible at the busiest times of the day.Because of the way tankless water heaters heat water, it is common to receive a slug of cold water after turning on the hot water, turning it off, and then turning it back on again.

Cold water sandwich is the term used to describe this situation and it is not common with typical tank water heating systems.One of the most significant and least discussed disadvantages of tankless water heaters is that hard water can cause them to fail.Manufacturers’ warranties do not cover malfunctions caused by lime buildup, mineral buildup, or scale.

In the Takagi installation instructions, for example, it is specified that water hardness levels should not exceed 7 grains per gallon.The majority of cities in the Twin Cities metro region have substantially harder water than that: check the Water Hardness List for Twin Cities for more information.Hard water is difficult on all water heaters, but it is particularly difficult on tankless water heaters.Tankless water heaters in Minnesota have been known to fail as early as two years after installation owing to hard water deposits, according to a technician I talked with.Tankless water heaters must be cleansed on a regular basis in order to assist prevent an early death.

This is described as a ″simple procedure″ in the video below; nevertheless, have a look and determine for yourself whether or not this is an easy process.Tankless water heaters should also be emptied and their filters cleaned once a month, according to the manufacturer.Another disadvantage of tankless water heaters is that they require power to function.

  • If an outlet is required, the cost of installation will be higher as a result.
  • This also implies that there is a far greater likelihood of anything going wrong.
  • Take, for example, the following array of trouble codes for a particular tankless water heater: Also, have a look at this cut-away picture of a Rinnai tankless water heater to get a better understanding of how much technology goes into these devices: Low flow rate equals no hot water.
  • For tankless water heaters to function properly, they must have a consistent flow rate in order to turn on and keep the water heater operating.
  • Some systems, for example, will only work when there is a flow rate of 1/2 gallon per minute of water flowing through them.
  • According to what I’ve heard, this may be a serious problem in older homes with galvanized water pipes that are only capable of producing 1/2 gallon per minute of flow at most.


When it comes time for me to replace my own water heater, I’m thinking I’ll continue with my current conventional tank.For me, the greater expense as well as the increased likelihood of complications just exceed the additional benefits.In the event that I ever make the decision to install a tankless water heater, I will almost certainly spend a significant amount of time looking over the specifications of the individual type that I pick.Aside from ensuring that the unit is suitably sized, I’ll want to know what the manufacturer’s minimum flow rate is, what sort of water quality the company requires, and what precisely is covered by the manufacturer’s guarantee.The author is Reuben Saltzman, a Structure Technologist.
