Which Type Of Water Heater Is The Most Energy Efficient?
When it comes to selecting a water heater, there are several variables to consider.There are several variables to consider, including fuel type, water capacity, size, mode of operation, and cost.However, one of the most significant elements that homeowners are focusing more and more these days is energy efficiency.The efficiency of your water heater is measured in two ways: not just in terms of how much energy or fuel it consumes, but also in terms of how efficiently it retains and maintains water that has already been warmed.
- In this section, we will examine the various types of hot water systems and how they compare in terms of energy efficiency.
Conventional Storage Tank Water Heaters
Conventional hot water tanks are still the most popular choice for homeowners in the United States.Conventional tanks feature a supply of hot water that ranges from 20 to 80 gallons and is ready to be used immediately.The tank is filled with cold water from the bottom up, and it can be powered by electricity, natural gas, propane, or motor oil.Standing by heat loss from a water heater tank might occur when hot water is kept in a water heater tank throughout the heating season.
- Preventing heat loss is made easier by selecting a model with enough insulation (thermal resistance ranging between R-12 and R-25).
- The higher the capacity of your water heater tank, the less efficient it will likely be.
- When picking a water heater tank, keep in mind that the tank that is the cheapest up front may also be the one with the greatest running costs and yearly expenses, so make sure you consider both the short- and long-term costs when making your decision.
Tankless or On Demand Water Heaters
Tankless or on-demand water heaters are becoming increasingly popular as a result of their ability to save both energy and money.Tankless water heaters provide hot water on demand by heating water as it travels through a pipe using a gas or electric element, depending on the model.Because tankless heaters do not store hot water, there is no loss of heat during inactivity.The output of an instantaneous water heater, on the other hand, limits the flow rate of the heater.
- This implies that operating two hot water-using appliances at the same time, such as the shower and the dishwasher, may cause the tankless system to surpass its capacity.
- Tankless hot water heaters can be 24-34 percent more efficient for families that use 41 gallons or less of hot water per day, whereas tankless hot water heaters can be 8-14 percent more efficient for households that use a large amount of hot water per day.
Smart Water Heaters
Despite being a relatively new addition to the market, smart water heaters are essentially a combination of an electric water heater with an electronic thermostat and a digital user interface screen at their most basic level of sophistication.What distinguishes these water heaters as really intelligent is their ability to ″automatically adjust water temperature in response to user hot water consumption patterns in order to decrease standby heat loss and save money.″ The majority of them are also equipped with easy-to-read diagnostic and fault codes, which makes it much easier to schedule a service call with your plumber.
Power Vent Water Heaters
Power vent water heaters have grown increasingly popular in recent years due to the fact that they do not require a chimney or an upright vent to expel exhaust gases.A horizontal pipe system, driven by an electric fan or blower, allows the water heater to be installed virtually anyplace in the house or in houses without chimneys.For others, the additional electricity costs associated with running the vent fan, as well as the modest noise produced by the fan, are a detriment.The advantages of a power vent water heater, such as its ease of installation, make it a straightforward decision for the majority of homeowners – and their plumbers.
Heat Pump And Tankless Coil/Indirect Water Heaters
They create energy for heating your water by drawing on the heat from your home’s heating system or another heat source.However, it is vital to contact with a plumber to establish your requirements and the most appropriate water heater for you.It is possible to save money on your electricity bill while receiving a more steady and environmentally friendly supply of hot water by selecting the most energy-efficient water heater on the market.Magnificent Plumbing, your neighborhood plumber, may be reached at any time.
What’s the Most Energy-Efficient Water Heater?
The conventional 50-gallon water heater is the least likely of all the items that vie for a homeowner’s attention, including anything from vacuum cleaner robots to video-enabled door locks that serve as security guards.The tall metal cylinder that warms water for our sinks and showers is generally hidden from view in the basement or a dark utility closet, where it may operate dependably for a decade or more with little or no maintenance.However, there will come a time when that dependable water heater may develop a leak and shut down permanently, necessitating an urgent contact to a plumbing company.And it’s preferable not to put off the decision for too long.
- According to Pierre Delforge, senior scientist on the Natural Resources Defense Council’s building decarbonization team, the technological advancements and increasing energy efficiency found in the new generation of environmentally friendly heat pump water heaters (HPWH) make them a worthwhile investment for anyone looking to reduce both carbon emissions and utility bills at the same time.
- Using the same technology that refrigerators use to keep their contents cool, HPWHs create heat with no pollutants and use as little as one-half to a third of the energy required by a normal electric resistive or gas heater to achieve the same function.
- This technique, according to Delforge, ″is a game changer since it is 300 to 400 percent more efficient than traditional heating, requiring far less energy to deliver the same level of service.″ Here’s everything you need to know to make the transition.
Teasing Out the Costs
Water heaters of all varieties currently account for 19 percent of total residential energy use in the United States, accounting for more energy than both cooking and refrigeration combined.Approximately 40% of all American houses are fitted with electric resistance heaters, which demand unnecessarily large quantities of energy from the national power system and contribute to skyrocketing energy costs.This is compounded by the fact that gas and propane water heaters, which are now found in half of all U.S.houses, have the following impact: In the process, they emit greenhouse gases and harmful poisons such as nitrogen oxides, which have been related to a wide range of respiratory ailments.
- When compared to conventional gas-fired heaters that use pollution-spewing combustion to generate heat or electric heaters that use the same type of mechanism found in a toaster for heating, HPWHs use an energy-efficient compressor that collects and concentrates heat from the surrounding environment.
- This heat is then used to heat water in a storage tank.
- Energy Star’s consumer website estimates that the average four-person U.S.
- home will save around $350 per year on power costs, or $3,750 over the life of a standard high-efficiency water heater, as a result of using less water.
- (Actual savings will vary based on your area as well as the municipal or private utility that provides energy to your house.) – Residential energy efficiency is a key instrument in combating climate change, and adopting greener technologies such as this one is a valuable contribution for the homeowner who wants to make a significant contribution to the advancement of a low-carbon economy.
According to Delforge, ″We’ve made significant progress in decarbonizing the electricity industry, and we’re making progress in the transportation sector as well, with higher efficiency requirements and the electrification of cars.″ Using sustainable energy from the grid to decarbonize homes and businesses can help us get back on track, but we must do more to get there.
Water heater replacement is a simple and very cost-effective process that saves you money in the long term.The hybrid versions, which are available from well-known manufacturers such as A.O.Smith, Rheem, and Bradford White, are the most popular of the several types of high-efficiency water heaters now available.Along with compressors that warm water by absorbing heat from the surrounding environment, they are fitted with supplementary immersion heating units to further warm it.
- In addition, these components are programmed to activate automatically during periods of high demand, providing peace of mind that the hot water will not run out even when the house is full with visitors.
- In fact, the initial cost of investing in modern HPWH technology (from $1,100 before incentives) is more than the cost of a traditional water heater (from $300), which is understandable.
- However, the increased expense will be more than compensated by the savings that will accrue during the appliance’s lifetime—which, in some situations, will be as little as two to three years.
- A rising number of municipal utilities are giving incentives to minimize the upfront cost, making the HPWH an even more attractive proposition for consumers.
- For the purchase and installation of a new heater, you’ll almost certainly need to hire a professional contractor unless you’re a qualified plumber (and have the permission necessary by many localities).
Plan to chat with a number of plumbers in your region in order to discover those who have previous expertise with high-pressure water heaters.The fact that HPWHs represent just 2% of the water heating industry means that many contractors will be inexperienced with them, and some may even try to push you away from energy-efficient solutions since they are more comfortable with regular heaters.A competent specialist may also advise you on the best appliance to purchase for your house; many municipal utilities maintain a list of qualified contractors in their service areas on their websites, which you can consult.As a general guideline, you should pick a water heater with a water tank that is larger than the one that is generally advised for the size of your home.
This will allow you to avoid using the hybrid unit’s less-efficient high-demand auxiliary feature, which is less efficient.In the case of a bigger tank that fills with hot water overnight, there will be no scarcity of hot water during bathroom rush hour the following morning.When you consider the long-term benefit of an HPWH, the extra expense of going larger is justified.In addition to allowing you to take use of clean energy at a lesser cost, water heaters with smart thermostats that commence heating during off-peak hours (when there is less demand for electricity consumption) provide enough of hot water when you need it the most.According to Delforge, they effectively serve as ″batteries″ for storing renewable energy.
It is simple and extremely cost-effective to upgrade your water heater in the long term.Hybrid versions are the most popular of the several types of high-efficiency water heaters presently available from well-known manufacturers such as A.O.Smith, Rheem, and Bradford White.They are fitted with supplemental immersion heating devices in addition to compressors that warm the water by absorbing heat from the surrounding environment.
- These components are programmed to turn on automatically during periods of heavy demand, providing peace of mind that the hot water will not run out even when the home is crammed with people.
- In fact, the initial cost of investing in modern HPWH technology (from $1,100 before incentives) is more than the cost of a traditional water heater (from $300), which is to be expected.
- Even so, the increased cost of installing the appliance will be more than covered by the savings that accrue during the device’s lifetime—which in some circumstances will be two or three years in certain situations.
- The HPWH is becoming an even better value as a rising number of municipal utilities are giving incentives to lower the upfront cost.
- A professional contractor will most likely be hired to purchase and install a new heater unless you’re a qualified plumber (and have the permission necessary by many towns).
Identifying plumbers who have experience with high-pressure water heaters (HPWHs) is something you should plan to discuss with many in your neighborhood.Because they now account for only 2 percent of the water heating industry, high-pressure water heaters (HPWHs) may be uncharted ground for many contractors, who may even try to push you away from energy-efficient solutions simply because they are more experienced with traditional heaters.You may also get advice from a certified specialist on which appliances to buy for your house; many municipal utilities maintain a list of authorized contractors in your area that you can contact directly.Generally speaking, you should select a water heater with a water tank that is larger than the one normally advised for the size of your home.
This will allow you to avoid utilizing the hybrid unit’s less-efficient high-demand auxiliary mode, which will save you money.For example, a bigger tank that fills with hot water overnight will prevent a scarcity of hot water during bathroom rush hour the following morning..A higher capacity HPWH is worth the additional expense when considering its long-term benefit.Warming water heaters equipped with smart thermostats that begin heating during off-peak hours (when there is less demand for electricity use) have the additional benefit of allowing you to take advantage of clean energy at a lower cost while still providing plenty of hot water when you need it the most.The clean energy ″batteries,″ as Delforge describes them, serve to store renewable energy.
Evolving Technology: The Space Heater That Also Does Air-Conditioning
- Heat pump technology may be used to heat and cool air in addition to heating and cooling water, making it a more energy-efficient alternative to typical air conditioners (ACs) and furnaces than traditional heating and cooling methods.
- Heat pump space heaters, like heat pump water heaters (HPWHs), simply transport heat from a cool room to a warm space rather than generating heat by burning fuel, cutting emissions and lowering your electricity cost in the process.
- As a two-in-one system, a heat pump provides both heating and cooling for the price of one.
- This is one of the most significant advantages of having a heat pump.
- Alejandra Mejia Cunningham, an advocate for building decarbonization at the Natural Resources Defense Council, believes that a lack of familiarity with the technology is part of the reason for its slow adoption.
- ″People are most at ease when they are doing what they have always done,″ she points out.
- ″It is the responsibility of policymakers to offer the appropriate incentives to assist customers and installers in becoming more aware with and enthused about these innovative, healthy, and climate-friendly technologies,″ the authors write.
- At the moment, just 11 percent of households in the United States utilize heat pumps for space heating and cooling, according to the Energy Information Administration.
If this technology becomes the standard for those building new air conditioners, we may see them in as many as 44 percent of houses by 2032, according to estimates.Stories from NRDC.org are accessible for online reprinting by news media outlets or nonprofit organizations under the following conditions: It is necessary to give credit to the author(s) and to note prominently that the story was originally published by NRDC.org and link to the original; the story cannot be edited (beyond simple things such as time and place elements, style, and grammar); you cannot resell the story in any form or grant republishing rights to other outlets; you cannot republish our material in bulk or automatically—you must choose stories one at a time; you cannot republish our photos or graphics; and

- A warm shower sounds wonderful while you’re trying to rekindle life in your freezing body, but when you turn on the hot water faucet, all that comes out is ice cold water.
- Your water heater has died, and the timing couldn’t have been more inconvenient.
- In an ideal world, water heaters would be indestructible, withstanding any test of time or durability.
- However, in reality, the ordinary water heater only lasts 8 to 12 years on the average.
- It’s possible that when it comes time to replace your water heater, you’ll quickly discover that not only are there numerous different types of water heaters available, but each has its own set of advantages and disadvantages.
- With so many current alternatives available on the market, it is always preferable to be well-informed about your various possibilities rather than relying on chance or a possibly biased specialist to make the decision for you.
- There are five basic types of water heaters: conventional, tankless, heat pump, solar, and condensing.
Conventional water heaters are the most common form.Each has its own set of technical breakthroughs and energy-saving features, so taking the time to learn about the differences between them can help you make an informed purchase.Here, we’ll walk you through each of the five water heater kinds and discuss their advantages and disadvantages as well as the numerous reasons why one water heater may be a better choice for your house than another.Water heaters are available in a variety of configurations.
- Water heaters are classified as follows: conventional water heaters, tankless water heaters, heat pump water heaters, solar water heaters, and condensing water heaters.
Types of Water Heaters
1. Conventional Water Heater
- Conventional water heaters are one of the most popular types of water heaters available today. They are equipped with a large insulated tank that stores and warms the water they use. Pros: Lower initial investment costs: With the exception of ultra-modern models, you will almost certainly spend less money on the initial up-front charges of a traditional water heater than you would on any of the other three options.
- Efficacious in all weather conditions: No matter where you reside in the globe, you can rest confident that a conventional water heater will perform to the highest standards. Solar, tankless, and heat pump water heaters all require precise environmental conditions in order to work at their best.. As long as adequate maintenance is performed on a conventional water heater, it will provide consistent and trouble-free service.
- Installation expenses are reduced because: Traditional water heaters are also rather affordable to install, in addition to having low upfront expenditures to begin with. This, of course, is dependent on where in your home you intend to put the system, as well as whether or not you will require plumbing, gas, or electrical arrangements. Generally speaking, installation expenses are less expensive than those associated with alternative installation methods.
- Cons: Because traditional water heaters provide a continual supply of warm water, they consume a significant amount of electricity to keep the temperature constant in the tank. Tankless water heaters, on the other hand, only heat water when it is needed.
- A traditional water heater is a space hog, and there’s no getting around it’s dimensions. Because they are intended to house a reservoir of warm water, they tend to be on the bigger end of the size spectrum.
- Damage caused by water is a concern: When it comes to traditional water heaters, their propensity for water damage has been identified as one of its most serious lethal defects. Without doing regular routine maintenance checks on your water heater, you may find yourself dealing with rust and corrosion, which might compromise the performance and overall health of your water heater. The consequences of this might include substantial, and hence quite expensive, water damage to your property
2. Tankless Water Heater
- Through the use of superheated coils, tankless water heaters are capable of producing immediate hot water. These coils fill with water as soon as you turn on the faucet, providing virtually infinite hot water for your household. Pros: Water that is instantly hot: In contrast to conventional water heaters, which require time for chilly water to become warm and warm water to become hot before providing hot water on demand, tankless water heaters give hot water instantly when you need it. Given that tankless water heaters only heat water when it is needed, they consume less energy in general, particularly when compared to a traditional heater that maintains an even temperature throughout the year
- Space-saving: Its small footprint is one of the most noticeable advantages of a tankless water heating system. Tankless versions do not necessitate the use of a large amount of storage space since they do not require a continual supply of water. This makes it simple to hang them on walls or store them in confined spaces such as nooks and crannies
- Reduced month-to-month expenses: The installation of a tankless water heater in your house will significantly reduce your monthly bills, as well as save you hundreds of dollars on a yearly basis. The reduced demand for energy flow allows you to reap the benefits of your power-saving decision while spending less money.
- A higher initial investment is required for tankless water heaters, even the most economical of which start at $1, 000, whereas the average conventional water heater will cost approximately $500. However, while there are several advantages to making the transition, people on a tight budget will have to wait a while before making up for the cost difference.
- A limited amount of hot water is available A tankless water heater is ideal for small families
- but, if you have a bigger family, the supply of hot water may become insufficient if there are too many demands placed on it at the same time. For example, if someone is having a shower while the dishwasher is running, it is possible that the hot water demand will decrease and become chilly.
- When compared to similar affordable alternatives, there is no discernible advantage: Tankless water heaters are much more expensive than a variety of other water heater options, but they do not often come with a slew of really beneficial features that are difficult to come across with less expensive alternatives. Depending on your situation, it might take anywhere from 6 to 12 years to recoup your startup and installation expenditures before you start saving money on a monthly basis.
3. Heat Pump Water Heater
- Heat pump water heaters, also known as hybrid water heaters, are designed to function without the use of direct heat generation to heat the water they heat.
- With heat being drawn from the earth and surrounding air, the only power required is for the purpose of transporting heat from point A to point B.
- Pros: Money-saving: Energy-efficient heat pump water heaters, according to Consumer Reports, consume around 60% less energy than traditional water heaters.
- Even though heat pump heaters have a higher average cost of operation than tankless versions, you will realize the benefits of energy savings sooner than with tankless units.
- With a heat pump system, you can conserve water at home without having to modify your habits.
Efficiencies over the long term: Heat pump water heaters are the most energy-efficient alternatives to traditional gasoline, oil, and electric water heaters. Heat pump water heaters hold a lot of potential for individuals who are looking for a water heater that is both energy-efficient and cost-effective in its operation.
- Heat pump systems require far less maintenance than other types of heating and cooling systems.
- By requiring just one annual check-in, maintaining your hybrid system in good working order is simple and can be performed without the assistance of energy-efficient HVAC specialists or the payment of expensive labor expenses.
- Every 3 to 5 years, it is suggested that you get your system inspected by a specialist.
- Cons: Heat pump water heaters have a very short life expectancy, often ranging from five to ten years on average. Heat pump water heaters fall short in contrast to solar and tankless heaters, which have an average lifespan of 20 years, and conventional systems, which have an average lifespan of 10-15 years.
- For heat pump water heaters to work safely and efficiently, they require at least 1,000 cubic feet of area. In addition, it’s important to note that hybrid water heaters can only be placed in areas with temperatures ranging between 40 to 90 degrees Fahrenheit—so people living in colder climes or hotter climates may be out of luck.
Despite the fact that heat pump water heaters do not directly generate energy, they are heavily reliant on it in order to operate properly. It is probable that anyone searching for a water heater choice that would help them lower their carbon footprint will disapprove of this carbon-neutral unit.
4. Solar Water Heater
- Solar water heaters rely on the energy provided by the sun. These systems function by transferring energy through a closed-loop system that links to a water tank, which subsequently heats the water. Pros: It makes use of renewable energy sources: Solar water heaters are the most energy-efficient water heater choices available on the market at the present time. In part due to the fact that solar energy is fully reliant on sunlight, it may be harvested wherever the sun’s rays shine on any given day.
- Lowering the cost of utility bills: Solar panels are not only highly environmentally friendly, but they are also incredibly cost-effective. While the initial installation costs may leave a hole in your pocketbook, switching to solar energy might result in large savings on both your water and power bills
- therefore, it is worth the investment.
- Eligibility for a tax credit: The federal government has made a significant push in the direction of encouraging solar-energy installations. There are a variety of federal tax credits available to help with the installation fees that may be incurred
- they are shown below.
- Cons: Only works well in warm climates with ample of sunlight: If you live in a gloomy place or in a climate where there are more rainy days than sunny days, investing in a solar water heater may not be as beneficial as it would be for inhabitants of Southern California or coastal Florida. Despite the fact that solar energy may be harvested on gray days, a string of low-sun days might have a considerable influence on the performance of your system.
- The cost of the installation is: One of the most significant drawbacks of solar water heating is the high expense of putting solar panels on your roof. If you’ve decided to make the move to solar energy, there are a variety of financing options available to make the payment process easier.
- Rooftop space needs include the following: The greater the amount of power you use from your solar panels, the greater the number of solar panels you will really require. The greater the number of solar panels you have, the more roof space you’ll need to commit to them. If your house is modest in size, it is possible that your roof will not be able to handle the amount of solar panel electricity you require.
5. Condensing Water Heater
- While condensing water heaters are similar to conventional heating systems in their operation, they differ in that they capture hot exhaust gases that would otherwise depart the home through a flue and redirect them to a heat exchanger installed within the tank. Pros: Environmentally preferable options include: According to ENERGY STAR, condensing water heaters can help you save up to 30% on your energy bills if you pair them with an ENERGY STAR approved heating system in your house. This alone helps you to reduce your carbon footprint by lowering your greenhouse gas emissions production
- but, there are further benefits.
- Operating costs are lower: Consistently designed with efficiency in mind, condensing water heaters have the potential to dramatically lower your natural gas expense.
- The efficiency of condensing water heaters is that they are capable of providing hot water in the same amount of time and space as tankless water heaters. The tank warms up the water as rapidly as it is filled, allowing you to enjoy a near-constant flow of hot water whenever you want it
- Costly initial investment: Newer condensing water heater types can cost up to three times as much as a traditional water heater—and that’s just for the first investment. While installation costs for condensing systems are often cheaper than those for conventional heaters, the savings on the original investment may not be enough to offset the difference.
- Switching to a condensing water heater is not as easy as a quick installation
- it is a time-consuming procedure that necessitates a significant amount of reconfiguring on the part of the homeowner. Before making a final choice on everything from gas lines to venting alignments, make sure to include in all of the hidden costs.
In terms of capacity, most condensing water heaters can hold up to 56-gallon water tanks or more, indicating that they’re built for heavy-duty water use. As a direct result of this heavy-duty capabilities, the heater itself is rather large in proportion to its capacity. This massive machine will require its own dedicated location, which you will need to set aside.
Before selecting on the best form of water heater for your family, you should conduct extensive research and qualitative evaluation. When you have a thorough awareness of everything accessible to you on the current market, you can be comfortable that you are making the greatest and most educated option possible for your situation.
Water Heater Buying Guide
- In a recent test, Consumer Reports evaluated six electric and gas whole-house tankless water heaters from companies like Bosch, Navien, Noritz, Rheem, Rinnai, Tempra, and Trutankless, among others.
- A tanked water heater from Rheem, one that is gas and one that is electric, as well as an electric heat pump water heater from Rheem, which is a variant on a tanked water heater, were all used to compare the outcomes.
- Based on the results of an industry-standard ″heavy usage″ test, we compared the performance of natural gas and electric tankless water heaters to that of their conventional tank equivalents.
- The test was conducted using a high draw pattern, which equated to the use of 84 gallons of water per day.
- The daily equivalent of taking many showers, running the dishwasher, washing one load of clothes, and repeatedly turning the tap on and off.
- Temperatures at the intake for gas models were 58° F, while temperatures at the outlet for electric models were 74° F (plus or minus 2° F).
- The intended outlet temperature was 120° F, and the test employed these temperatures.
- The tankless water heaters performed so similarly to one another that we calculated an average of the results from each batch, both gas and electric, and compared that score to the performance of the conventional gas and electric storage tanks, as well as the performance of the electric heat pump model, to determine the winner.
As a result, we do not have model-level ratings for refrigerators, as we do for other major appliances.We computed the payback period for both new and replacement installations based on the purchase price, yearly energy cost, and an estimate of the cost of installation, among other factors.Tankless units that were installed in lieu of an existing storage tank had a longer payback period than those installed during new construction.For further information, see our reviews of gas and electric water heaters.
Tankless hot water heaters vs Tank storage water heaters.
- Water heaters may be a pricey purchase for homeowners, especially if you plan on staying in your house for more than a decade.
- As a result, when it comes time to furnish your new home or replace your old water heater, it is critical to evaluate the cost, efficiency, and durability of your new water heater.
- The following comparison of storage water heaters vs tankless water heaters is intended to assist homeowners and contractors in deciding on the kind of water heater that will work best for them.

What Is a Tankless Water Heater?
- Tankless water heaters, also known as on-demand water heaters, utilize high-powered burners to rapidly heat water as it passes through a heat exchanger, allowing it to be delivered straight to your taps or shower without the need to store it in a storage tank beforehand.
- Water heaters that do not require a tank are often fueled by electricity or gas.
- In studies done by Consumer Reports, it was discovered that these sorts of water heaters were on average 22 percent more energy efficient than gas-fired storage-tank devices on a national scale.
How are “Traditional” Tank Storage Water Heaters Different?
- Storage tank water heaters are prevalent in most households, and they provide plenty hot water.
- Their main component is an insulated tank, which can normally contain 30-50 gallons of water and is used to heat and store the water until it is required.
- In order to bring hot water to its destination, such as the kitchen, the bathroom, or other sinks, a pipe emerges from the top.
- Storage-tank water heaters are often powered by either natural gas or electricity, depending on the model.
- Natural gas storage-tank water heaters consume about half the energy of electric storage-tank water heaters and run at a fraction of the cost.
- They do, however, come at a somewhat higher price than electric versions.
- They also have a temperature and pressure release valve, which opens when either the temperature or the pressure exceeds the predetermined values.
Tankless Water Heater Energy Efficiency
- On-demand (tankless) water heaters provide between 24 and 34 percent more energy efficiency than storage tank water heaters for homeowners who use less than 41 gallons or less of hot water per day.
- Storage tank water heaters provide between 24 and 34 percent greater energy efficiency.
- It is possible to gain an extra 8 to 14 percent in energy efficiency if you consume large amounts of hot water on a daily basis (about 86 gallons).
- When comparing tankless water heaters and traditional storage tank water heaters, tankless varieties have a longer useful life than conventional models, which translates to a 20+-year useful life as opposed to storage tank types, which have a useful life of 10 to 15 years before self-destructing and flooding your basement or home, depending on where they are located in your home.
- In order to ″hit a home run,″ it is recommended that a tankless water heater be installed at each hot water outlet.
- On-demand water heaters installed at all hot water outlets in your home can result in energy savings of 27 to 50 percent, depending on your usage pattern.
Pros & Cons of Tankless Water Heaters
Because there are no ideal goods (tankless water heaters are no exception), there are advantages and disadvantages to on-demand water heaters, as with any other product.
Tankless Water Heater Advantages:
- Over time, it saves you money.
- According to Energy.gov, ″demand (or tankless) water heaters can be 24 percent to 34 percent more energy efficient than conventional storage tank water heaters for homes that use 41 gallons or less of hot water daily.″ Demand (or tankless) water heaters can be 24 percent to 34 percent more energy efficient than conventional storage tank water heaters. Tankless water heaters (especially if they are gas-fueled) can save households more than $100 per year if they are kept in operation for a long time. According to the United States Department of Energy, electric tankless water heaters continue to save homeowners around $44 per year.
- Water heaters with a longer useful life than storage tank water heaters
- Tankless water heaters generally have a lifespan of 20 to 30 years, which is double the expected usable life of a storage tank water heater, according to the manufacturer. Keep in mind that places with ″hard water″ may see a reduction in the usable life of both types of water heaters.
- It does not take up the same amount of room as a storage tank water heater.
- As a result of their size, on-demand water heaters may be put in ″close quarters.″ They can also be put on the outside of your home if you have a very limited amount of available space.
- You will have access to hot water anytime you require it.
- When you use a tankless water heater, you won’t even have to wait 15 to 25 seconds for your water to get hot because they produce two to three gallons of hot water each minute. As a result of the increased amount of water they must heat, many storage tank water heaters take longer to heat water than tankless water heaters
- however, this is not always the case.
Drawbacks of Tankless Water Heaters:
- Water heaters with storage tanks have a higher initial purchase cost.
- It can be very expensive to install a tankless water heater, especially if you’re replacing an existing storage tank water heater with a tankless water heater.
- Because it is more difficult to relocate existing pipe when you opt to retrofit a tankless water heater instead of a storage tank water heater, your plumber-installer will require more time, which will increase the installation cost, when replacing a storage tank water heater.
- They have the potential to be ″output challenged.″
- When you are taking showers and doing laundry at the same time, your tankless water heater may not be able to keep up with the demand for hot water placed on it. With many showers in your home, it is common for one of the shower-takers to have a ″chilly″ experience
- however, this is not always the case.
Pros & Cons of Storage Tank Water Heaters (Tank) Water Heater Advantages:
- Storage tank water heaters have a significantly cheaper starting cost than other types of water heaters.
- Storage tank water heaters are less complicated to run than tankless models, resulting in less expensive maintenance and repair costs.
- When tankless water heaters are not operating correctly, their simplicity allows for quick and low-cost repairs to be performed. Tankless water heaters are more complicated and expensive to fix and, of course, to replace than traditional water heaters.
Drawbacks of Storage (Tank) Water Heaters:
- Utility bills that are a little higher
- Because storage tank water heaters heat and then reheat water to a pre-set temperature, regardless of how much hot water you use, they raise your utility rates a little. If these water heaters are operating in a chilly environment (location), they will have to work harder during the winter months, increasing your gas or electric expenditures even more during the cold winter months.
- Storage tank water heaters require more room than on-demand water heaters due to their larger size
- if you live in a small place, you may have difficulty finding adequate space to accommodate storage tank water heaters. Additionally, unlike tankless water heaters, they cannot be installed outside the home.
- You don’t want to be the last member of your family to get out of the shower
- If you have a standard household water heater, you may wish to upgrade to a bigger one if you take many showers on a regular basis. While this solution may alleviate the hot water deficit, your energy expenditures may rise in tandem with the reduction in hot water supply. Storage tank water heaters are only capable of supporting three showers in a succession on average. It’s not pleasant to be the fourth shower-taker unless you favor frigid showers rather than hot showers
- Tank-style water heaters must be changed more frequently than tankless water heaters.
- Given that storage tank water heaters have a lower functional life (approximately a quarter of the life of on-demand water heaters), often 10 to 15 years, you may be required to purchase and install them nearly twice as frequently as tankless water heaters, diminishing your purchasing savings.
- A tankless water heater can save you more money over the course of its lifetime if your bank account can handle the greater initial expense of such a water heater.
- However, if you have a fixed income and a low income, a storage tank water heater may be a better option for you.
