Tankless Water Heaters: 7 Pros and 6 Cons You Should Know
Tankless water heaters, also called on-demand or instant water heaters, have a number of advantages over traditional tank-style water heaters and can be an excellent long-term investment. However, as with any product, they have their drawbacks and are not the best solution for every home. Unlike traditional tank-style water heaters, which continuously use energy to maintain a hot water supply, tankless water heaters only use energy when you turn on a hot water tap or when you use hot water. Tankless water heaters have several advantages over tank-style water heaters, including the ability to provide an endless supply of hot water, taking up less space, being less prone to leaking, being safer, and having a significantly longer lifespan on average.
Tankless water heaters typically cost three times as much as tank-style water heaters, including installation.
- They take longer to supply hot water
- The temperature of the water is variable when numerous outlets are turned on at the same time
- And they are unable to deliver hot water during a power outage
Making the decision to purchase a tankless water heater is a challenging one, so it’s critical that you grasp all of the facts before making a final decision. The purpose of this essay is to give you with a complete summary of the advantages and disadvantages of tankless water heaters so that you can make an informed decision based on your specific scenario. Let’s get this party started. To jump to a certain part, simply click on one of the links below. The Benefits of Tankless Water Heaters include the following:
- Energy and cost savings over the long run are a plus. Pros: an unlimited supply of hot water
- A smaller footprint
- A lower risk of leaks and water damage
- And a lower cost. Advantage: There is no danger of the tank exploding. Benefits include a reduced risk of burns and exposure to toxic metals. Pro: A life expectancy of more than 20 years is expected.
The disadvantages of tankless water heaters are as follows:
- The unit and installation are expensive up front, which is a disadvantage. Cons: It takes longer for hot water to be delivered. Cons: Sandwich made with cold water
- If more than one outlet is used, the water temperature does not remain constant. The disadvantage is that it is difficult to get a lukewarm temperature. During a power outage, there is no access to hot water
- Disadvantage The bottom line: Is a tankless water heater a good investment?
Pro: Long-term Energy and Cost Savings
The most significant advantage of tankless water heaters is that they are energy efficient and so save you money over the long term of ownership. When a tank-style water heater is in use, it expends energy continuously to maintain the temperature of a 40 to 50-gallon water supply in order to ensure that hot water is available when it is required. In contrast to traditional water heaters, tankless water heaters heat water on demand rather than maintaining a constant supply of water. The lack of standby heat loss caused by tankless water heaters eliminates the need for regular warming of the water.
- It takes only seconds for the water to be heated and then circulated throughout your home through the pipes, where it is used to flush toilets and wash dishes.
- Water consumption and the efficiency of your previous tank-style system determine the amount of energy you will save.
- An electric tankless water heater is 24 percent – 34% more efficient than an equivalent gas tank-style heater when you consume less than 41 gallons of hot water per day.
- This is because they are running more often.
You can save anywhere between 27 percent and 50 percent. According to Energy Star, switching from a tank-style water heater to a tankless water heater can save a family of four an average of $100 each year, or more than $1500 over the lifespan of the system.
Pro: Unlimited Supply of Hot Water
Consider the following scenario: you return home from a day at the beach with your family and everyone in the house has to shower. The hot water has ran out after the sixth shower in a row, leaving you with no choice but to take a cold shower. That scenario will never occur if you have a tankless water heater installed. Allow me to explain. For each tankless water heater, there is a maximum flow rate; in other words, each tankless water heater can only heat a particular volume of water at any given moment.
For the time being, tankless water heaters provide an unending supply of hot water, provided that your water use is less than the maximum permissible flow rate at any one moment.
This is because tankless water heaters function by heating water from an external source on demand.
Pro: Take Up Less Space
Assume you have just returned from a day at the beach with your family and everyone in the house has to shower. The hot water has ran out after the sixth shower in a row, leaving you with no option but to take a cold shower. If you have a tankless water heater, you will never find yourself in this situation again. Now, please allow me to elaborate. There is a limit flow rate for each tankless water heater, which means that they are only capable of heating a particular volume of water at a given moment.
Tankless water heaters, on the other hand, provide an unending supply of hot water as long as your water use is kept below the maximum permissible flow rate at any one moment.
Pro: Lower Risk of Leaks and Water Damage
Consider the following scenario: you have returned home from a day at the beach with your family and everyone in the house has to shower. The hot water has ran out after the sixth shower in a row, leaving you with no choice but to take a cold shower. That circumstance will never arise if you have a tankless water heater installed. Please allow me to clarify. There is a maximum flow rate for each tankless water heater; in other words, they are only capable of heating a particular volume of water at a given moment.
Tankless water heaters, on the other hand, provide an unending supply of hot water as long as your water use at any one moment is below the maximum permitted flow rate.
Because tankless water heaters function by heating water from an external source on demand, you could take a shower for 10 hours (or longer) and the water would be as hot as it would be for a 10-minute shower.
Pro: Zero Risk of Tank Exploding
The current plumbing code mandates that all tank-style water heaters be equipped with a temperature and pressure relief valve, which opens to relieve pressure and prevent the tank from bursting. Temperature and pressure relief valves are two types of relief valves. Minerals and silt from the water might block the valve and prevent it from performing its job effectively over time. When this occurs, a potentially hazardous amount of pressure might build up, putting you in danger. If you have a tank-style water heater, experts recommend that you test the valve at least once a year; find out how to do so in the video below.
Tankless heaters, on the other hand, do not have a tank, thus there is absolutely no possibility of an explosion ever occurring.
Pro: Lower Risk of Burns and Exposure to Toxic Metals
The use of tankless water heaters, according to many experts, is safer than the use of traditional tank water heaters. Beyond the fact that they do not have a tank that may explode, they also offer more accurate temperature control, which means you are less likely to get burnt by hot water when using them. Additionally, as previously stated, tank-style heaters fail over time owing to hard water, which causes the inside lining of the tank to rust and corrode, leading the heater to fail. That mineral buildup and particle accumulation ultimately finds its way into your water pipes, exposing you and your family to potentially dangerous pollutants.
Pro: Life Expectancy of Over 20 Years
I recently released an essay on the issue of how long water heaters last and how to extend the life of your water heater. I hope you will find it informative. Tank-style water heaters have an average lifespan of 8 to 12 years; tankless water heaters, on the other hand, have an average lifespan of more than 20 years. If you’ve already found your “forever home” or want to remain in your current location for an extended period of time, investing in a tankless water heater will prevent you from having to replace your water heater for an extended period of time.
Con: High Upfront Cost of the Unit and Installation
The most significant disadvantage of tankless water heaters is the large initial investment required for the device and its installation. According to HomeAdvisor, the typical cost of a tank-style water heater with a capacity of 40 to 50 gallons, including installation, is $889. Installation of a tankless water heater costs around $3,000 on average. Tankless water heaters are more expensive than traditional water heaters, mostly because of greater installation expenses. Often, more wiring must be added in order to manage the higher load, and/or a new vent pipe must be erected to accommodate the increased load.
Tankless water heaters can also be harmed by hard water (water that contains high quantities of minerals), which makes them work harder and finally fail.
The cost of installing this additional component is added to the total cost of the project.
Please keep in mind that the prices shown above do not include installation. Tankless Water Heaters are a type of water heater that does not require a tank to be filled with water (links open listings on HomeDepot.com)

Con: Take Longer to Deliver Hot Water
Another disadvantage of tankless water heaters is that they create and supply hot water at a slower rate than traditional tank-style water heaters, which increases energy costs. Keep in mind that tankless water heaters do not maintain a constant supply of hot water that is ready to be used whenever you want it. When you turn on a hot water faucet, the water in the pipes is either cold or, at best, room temperature since it is not being used. Once the chilly water has been drained out, hot water will begin to flow through the faucet; however, it may take anywhere from a few seconds to a minute depending on the distance between the heater and the faucet.
Con: Cold Water Sandwich
In addition, as compared to traditional tank-style water heaters, tankless heaters require more time to create and provide hot water than they do. You should bear in mind that tankless water heaters do not maintain a constant supply of hot water that is ready to be used whenever you want it. When you turn on a hot water faucet, the water in the pipes is either cold or, at best, room temperature since it has been sitting there. Once the chilly water has been drained out, hot water will begin to flow through; however, this process may take anywhere from a few seconds to a minute, depending on the distance between the heater and the tap in question.
Con: Inconsistent Water Temperature When Multiple Taps/Showers/Appliances Are in Use
When I first started writing on this topic, I described a scenario in which your family returns home from a day at the beach and everyone has to shower. Using tankless water heaters in this situation allows your entire family to shower side by side without having to worry about running out of hot water at any point. The disadvantage is that tankless water heaters are unable to keep up with the demands of numerous showers operating at the same time. Having a shower and running the dishwasher at the same time is not only a problem with showers; depending on the size of your water heater, you might run into problems if you do both.
The amount of water that a tankless unit can heat in a given length of time is referred to as the flow rate.
The flow rates for each type of outlet are depicted in the chart below to give you a sense of the average flow rates.
|Outlet||Average Flow Rates (GPM)|
|Bathroom Faucet||.5 – 1.5|
|Dish Washer||1 – 1.5|
|Washing Machine (Clothes)||1.5 – 3|
|Shower||2.5 – 3|
When I first started writing on this topic, I described a scenario in which your family returns home from a beach day and everyone has to shower. The advantage of tankless water heaters in this situation is that your entire family can take showers back-to-back without worrying about running out of hot water. The disadvantage is that tankless water heaters are incapable of keeping up with the demands of numerous showers operating at the same time. This is not only a problem with showers; depending on the size of your water heater, you may experience problems if you run a shower and the dishwasher at the same time, for example.
The quantity of water that a tankless unit can heat in a given length of time is referred to as its flow rate.
It is measured in Gallons Per Minute (GPM), and the higher the GPG, the greater the amount of water that can be heated at once. Each type of outlet is shown by a bar chart, which provides an indication of the typical flow rates.
Con: Difficult to Achieve a Lukewarm Temperature
It is one of the less well-known drawbacks of tankless water heaters that they have difficulties producing water that is just warm enough to bathe in. Due to the fact that tankless water heaters require a minimum volume of water flow before they can be activated, there is a gap between entirely cold water and the coldest warm water that can be created by mixing hot and cold water in a single container. Because there are very few situations in which you will not be able to attain the temperature you require, this isn’t a major problem, but it is something to keep in mind, especially if you’re the sort of person who truly loves taking chilly showers.
Con: No Access to Hot Water During a Power Outage
When a storm comes through and takes out the power in your home, the hot water in your home is also gone. The energy source for tankless water heaters can be either natural gas or electricity, however even gas-powered tankless water heaters rely on an electric control panel to run the unit. As a result, regardless of the sort of tankless water heater you have, you will be without hot water if your electricity goes out. Compared to tankless water heaters, tank-style water heaters have a major advantage in this category.
Bottom Line: Is a Tankless Water Heater Worth It?
The use of tankless water heaters has a number of advantages over the use of conventional tank-style water heaters. They conserve energy (and so save you money), they give infinite hot water, they are tiny and compact, they never leak, and they do not contribute to the presence of hazardous metals in your drinking water. The best part is that they last twice as long as traditional tank-style water heaters. Alternatively, you’ll have to pay around $3,000 up front, and they deliver variable water temperature in various conditions, as well as leaving you without hot water in the event of a power outage, among other things.
Some basic questions to ask yourself include the following:
- What if you only have $3,000 to invest in an appliance that won’t pay off for several years and you don’t want to risk losing your money? Is your home a new build or do you intend to live there for an extended period of time (10 years or more)? Do you frequently run out of hot water as a result of taking multiple showers in succession? Was it possible for you to profit from additional room in your basement (and who couldn’t? )
If you responded “yes” to any of the questions above, a tankless water heater may be the best option for you. It’s generally best to hold off and stay with a tank-style heater if you responded “no” to one or more of these questions, particularly question1.

Purchasing a water heater is a significant home comfort investment because it is a piece of equipment that you will use on a daily basis for more than a decade. That’s why it’s so critical to pick a decision you’ll be happy with when it comes time to replace your water heater. Consider whether to continue with a tried and reliable storage-type water heater or make the switch to a tankless one.
This is one of the most critical decisions you’ll have to make in your home. We’ve put together this brief primer to assist you in understanding the advantages and disadvantages of each kind of water heater available.
Tankless water heater basics
When you use a tankless water heater, water is routed via a high-powered heat exchanger, which rapidly heats the water you need – and only the water you need (for obvious reasons, they are referred to as “on-demand” water heaters). Gas (propane or natural gas), electricity, or heating oil are the most common fuels for these appliances.
Tankless water heater pros and cons
- Water is heated instantaneously by a high-powered heat exchanger, which allows you to use just the water you require (this is why tankless water heaters are commonly referred to as “on-demand” water heaters, which is self-explanatory). Gas (propane or natural gas), electricity, or heating oil are the most common fuels for these appliances.
- Price difference in the beginning– Typically, a tankless water heater is three to four times more expensive than a storage-type water heater
- You’ll also pay more for installation, particularly if you’re replacing a storage water heater
- And, finally, you’ll spend more in the long run. When you intend to take many showers in separate bathrooms at the same time, or run a hot load of laundry while also taking a bath, your water heater may run out of steam (literally!) as it struggles to keep up with the demand. Make certain that your tankless water heater is appropriately designed to satisfy the water heating load of your house during peak consumption – call us for more information.
Conventional (storage-type) water heater basics
When the majority of people think of a water heater, this is the type of model that comes to mind. Their components include an insulated tank that can store anywhere from 30 to 50 gallons of water, as well as a burner that is placed within the tank that warms and reheats the water so that it is ready to use when the tank is filled. Fuel for storage-tank water heaters can be obtained from natural gas or electrical sources. Gas water heaters consume nearly half as much energy as electric water heaters, but they are significantly more expensive to purchase and install initially.
Storage water heater pros and cons
- Storage tank water heaters may be purchased for as little as $500 to $800, with installation costs that are much cheaper than those of tankless units. They also have a longer lifespan than tankless ones. When storage water heaters are maintained simply, they require fewer repairs and are less expensive to replace when necessary
- Utility bills will rise as a result of constant heat loss from the water in your water heater’s storage tank to the surrounding environment (known as standing loss). As a result, your water heater will be working harder throughout the day to keep hot water ready for use whenever you turn on your tap, shower, or appliance. That consumes your energy as well as your money. Large footprint– If you have limited room in your house or basement, it may be tough to install a 40- or 50-gallon storage tank
- Nonetheless, it is possible. A storage tank water heater can only handle roughly three showers in a succession on average, which is not ideal. You’ll have to wait until your water heater can heat up another batch of hot water if you’re person4 and you prefer to take a warm shower in the morning. Storage tank types have a shorter usable life (approximately one-half the life of on-demand water heaters) – generally 10 to 15 years – than on-demand water heater types.
If you are willing to take the risk and invest in a tankless water heater, the investment will pay for itself in the long run in the form of cheaper utility bills and a longer usable life – especially if you have a larger home and household. A storage-type water heater, on the other hand, may be a better choice if money is tight or if you just need a little amount of hot water (as in, if you’re a single person or a couple without children).

Advantage And Disadvantage Of Tankless Water Heater
A tankless water heater, often known as a “on-demand” device, is designed to heat water only when it is needed, as opposed to a more typical water heater that heats water in a tank and then discharges it. Tankless water heaters, without a doubt, have a number of advantages, but there are also some negatives to take into consideration. The pros and cons of tankless hot water heaters are demonstrated in this video.
Advantages and Disadvantages of Tankless Water Heaters
- Tankless water heaters are only activated when there is a demand for hot water in the home. This has the potential to lower energy bills by as much as 35% per year. It also has a high level of energy efficiency. In accordance with Energy Star guidelines, some tankless water heaters have energy factors as high as 95.
- Then there’s the question of dependability. If the unit is suitably designed, it should be able to offer a constant flow of water at the desired temperature levels with little effort. 5 to 7 liters of hot water per minute might be produced in this situation. There is just no end to their supply of water.
- In addition to that, there’s the issue of dependability. A correctly sized unit can simply offer a continuous supply of water at predetermined temperature levels if the device is properly designed and constructed. 5 to 7 liters of hot water per minute might be produced in this fashion. In fact, they never seem to run out of water.
- Another aspect of safety that an on-demand water heater excels in is reliability. This is owing to the fact that they only work when warm water is necessary, which ensures their safety. The opposite of this is true for self-storage units, which are generally always operational.
The most recent tankless water heaters are equipped with a number of unique technologies that increase their overall safety. Some of the most modern types, for example, are equipped with monitoring systems that offer information on water pressure and flow. In the unlikely event of a system breakdown, the machine would immediately switch off the heating.
Disadvantages of Tankless Water Heaters
- The most significant downside of tankless water heaters is the high initial investment required. Tankless water heaters will cost you twice as much as traditional storage tanks, according to industry estimates. A conventional classic tank-type water heater costs around $800 to purchase. Prices for standard tankless water heaters begin at around $1,600.
- In addition, there are charges associated with the installation. The cost of necessary plumbing might be prohibitively expensive. Be aware that tankless water heating devices require proper ventilation, which might be expensive to install. However, if you hire a reputable plumber, you may save much more money on these expenses.
- In places with hard water, a water softener must be installed in order to prevent the tankless water heater from becoming damaged.
- Another problem is the degree to which some units are overly convoluted. In contrast to traditional storage tanks, upgrading a home with a tankless unit may be a time-consuming and expensive endeavor. To do the task correctly, you will want the services of a qualified plumber.
Benefits Of Tankless Water Heater In Your Budget
You may save money by just boiling water when it is actually needed. Whereas a tank water heater wastes energy by heating water that isn’t being used, a tankless water heater saves energy by only utilizing gas when you actually need it. This has the potential to reduce your expenditures by up to 30% every year! For any of your home servicing and repair requirements, please contact us at (214) 238-8353.

What Is a Tankless Water Heater?
Tankless water heaters produce hot water on demand, making them more energy-efficient than typical storage tank water heaters of the same size and type. Cold water goes through the tankless unit and is heated by either gas or electricity, resulting in a continuous supply of hot water that lasts until the faucet is turned off or turned off. They are sometimes referred to as instantaneous or demand-type water heaters as a result of their ability to respond quickly to demand.
It is more energy efficient than a storage tank water heater according to the United States Department of Energy, as long as you consume roughly 41 gallons of water per day and do not use more than one tank at the same time. But even if you quadruple that amount, they are still 8 percent to 14 percent more efficient than before. If you install a tankless water heater at every area where you consume hot water, you might save as much as 50% on your energy bills. When compared to a storage-tank water heater, this represents a significant advancement.
A tankless water heater will pay for itself in a matter of years, especially if you reside in a region where energy prices are high.
Hot Water Supply: Because tankless water heaters heat cold water on demand, it is possible to have hot water for an endless period of time as long as the faucet is left running.
Limited Hot Water for Multiple Outlets: A tankless water heater is only capable of heating a limited amount of water at a given time. Because the water heater is attempting to supply hot water to three different locations at the same time, the water temperature will fluctuate if you use more hot water than the unit can produce. For example, if you use your dishwasher, washing machine, and shower at the same time, your water temperature will fluctuate. Installing more than one unit or reducing the amount of hot water used can help to mitigate this problem.
Tankless water heaters might not be the ideal option if you reside in a region where power outages are often.
A tankless water heater is more expensive up front than a standard storage tank water heater, both in terms of the equipment and the installation. While the cost of a tankless water heater may initially dissuade you, bear in mind that, due to its extended lifespan and energy savings, it will pay for itself within a few years.
A tankless water heater’s typical unit cost is somewhat higher for natural or propane gas devices ($1,000 to $1,500) than for electric versions ($500 to $1,000).
Gas variants cost around $1,500 to $1,500 to install; electric models may be less expensive, costing $800 to $1,500 to install. Depending on the intricacy of the installation, you may expect to pay a skilled plumber between $45 and $150 per hour. Notably, many tankless water heater models will be eligible for a 10 percent federal tax credit, which may assist to offset the cost of purchasing and installing one. An experienced specialist should always be hired to complete the installation of a tankless water heater.
In many areas, there are rules that must be followed and licenses that must be obtained before a new heater can be installed properly.
Maintenance and Care
Tankless water heaters need to be serviced at least once a year, if not more frequently. In the course of time, minerals accumulate inside the water heater, necessitating the flushing of the entire system in order to avoid damage or a reduction in performance. If you reside in an area where the water is hard, you should consider flushing your toilet at least twice a year. Maintenance is required to maintain your model in excellent condition, especially because most warranties do not cover damage caused by mineral build-up on the surface.
Check your owner’s handbook to find out how often you should clean these filters, as the frequency varies depending on the model.
To minimize dirt collection on the outside of your tankless water heater, dust and clean it down regularly.
While you may complete all of these maintenance procedures on your own, if you discover substantial damage or detect anything concerning, switch off the power to your machine and contact a professional plumber right once to assess the situation.
Tankless water heaters have a lifespan of 20 years or more. Compared to the lifespan of a storage water heater, this is a huge improvement (anywhere from eight to 15 years). If you want to live in your house for a long period of time, investing in a tankless water heater eliminates the need to purchase new heaters on a regular basis, resulting in significant financial savings.
Tankless water heater manufacturers and brands may be found in abundance. When purchasing, search for a model with an Energy Star rating, which is a government-certified certification that indicates the model is among the most energy-efficient of all the models currently on the market.
- Rinnai: Rinnai is the most widely used tankless water heater producer in the United States and Canada. They only make gas-powered versions, but all of them are capable of heating enough water to supply a standard-sized home. Rheem: Rheem is well-known for manufacturing dependable, reasonably priced gas and electric heating and cooling equipment that are simple to install and maintain.

6 Benefits & Drawbacks of Tankless Water Heaters
When it comes to purchasing a new hot water heater for your house, there are a plethora of alternatives available. Should you use a standard water heater and pay to have the water heated on a continuous basis? Is a tankless water heater a better solution in this situation? For your convenience, we’ve collected a summary of the advantages and disadvantages of tankless water heaters to assist you in determining which is the best option for you and your family.
Pros of a Tankless Water Heater
Tankless water heaters are both energy efficient and cost effective. Despite the fact that classic hot water heaters are insulated, the insulation is not intended to keep heat from escaping. A classic hot water heater works by continuously heating the water in the tank, which allows it to deliver on-demand hot water. Because of the ongoing heating, the overall cost of your energy bills might rise month after month. A benefit of acquiring a tankless water heater is that it provides rapid and easy hot water while consuming less energy.
When compared to standard tank water heaters, tankless water heaters have a significantly longer life cycle—up to two times as long, in some instances. Traditional water heaters have a lifespan of 10-12 years, but tankless water heaters have a lifespan of up to 20 years. If you want to remain in your house for the foreseeable future, investing in a tankless water heater can help you avoid the expense of an expensive replacement in the future.
When compared to standard tank water heaters, tankless water heaters have a longer life cycle—up to twice as long, in some cases. Traditional water heaters have a lifespan of 10-12 years, but tankless water heaters have a lifespan of up to twenty years. Investment in a tankless water heater will save you money on future water heater replacements, especially if you expect to stay in your home for a long time.
Cons of a Tankless Water Heater
With 40-60 gallons of water stored in reserve at all times, a typical water heater has the potential to work on a larger scale, allowing many people to use hot water while bathing, cleaning dishes, and running the washing machine all at the same time, without running out of hot water. The lower output of hot water produced by tankless water heaters is a downside of the technology. If you run your dishwasher and shower at the same time, you may find yourself running out of hot water quickly.
Regardless of whether you go for an electric or a gas water heater, you should be aware of the massive amount of energy required when first turning on a tankless water heater. Because a typical water heater includes reserves, it requires less energy to heat the water throughout the course of its life. In order for a tankless water heater to begin producing hot water for your family, a significant quantity of energy is required.
The amount of instantaneous energy available through your gas or electric connection may dictate whether you should pick an electric or gas tankless water heater in certain cases and vice versa in others for your tankless water heater.
High Upfront Cost
Despite the fact that a tankless water heater has a longer life cycle, one of the disadvantages of this type of water heater is the large initial investment required. It is possible that tankless water heaters will cost between $200 and $300 more than a regular water heater, depending on the models you compare. However, because of the greater savings on your monthly energy bill, this additional cost may not have a significant impact on your purchase choice.

Pros & Cons of Tankless Water Heaters – Energy Conservation & More
Most of the time, you probably don’t pay much consideration to the water heater in your household. After all, like other household equipment, if it’s doing its intended function, it’s best to keep it out of sight and out of mind. However, if your present water heater is nearing the end of its useful life or you’re seeking for a more energy-efficient water heating option, it may be time to take a closer look at an on-demand – or tankless – water heater. So, first and foremost, what exactly is a tankless water heater?
THE PROS TO USING A TANKLESS WATER HEATER
Going tankless has a number of advantages, including the following:
- Because of their tough structure and materials, they often have a long life expectancy, and their running expenses are normally relatively cheap. Furthermore, because most models include replacement parts, there is less of an influence on the environment over the long run. Never-ending hot water: However, unlike storage tanks, which are restricted by the capacity of the tank – as you are reminded bitterly in the morning when all of your children shower before you do – tankless water heaters are capable of providing continuous hot water as long as there is fuel or electricity to heat it. Energy conservation: As soon as water is allowed to stay in a tank, it begins to lose heat, necessitating the constant switching on and off of a standard water heater in order to keep the water warm and ready to use. Because tankless water heaters heat water rapidly and only when it is needed, they are more energy efficient than traditional water heaters. As a matter of fact, our condensing models have an energy factor of 0.94, which indicates that 94 percent of the fuel is used to heat the water and just 6 percent is lost. A tankless water heater might help you save money on your energy bills. Room saving: Due to the high cost of real estate, many of us are opting to live in smaller houses. With less available space, a massive 40- or 60-gallon storage tank that is 5 feet high and 2 feet wide isn’t exactly practical. As opposed to traditional water heaters, a tankless water heater hangs on a wall high and out of the way, freeing up more useable area on the ground — just image how much more space you’ll have in your cottage, bathroom, or basement
- Reduced environmental impact: Tankless water heaters not only minimize the use of nonrenewable fuel sources, but they are also repairable with replacement components, as opposed to traditional water heater tanks, which are frequently need to be replaced completely.
THE CONS TO USING A TANKLESS WATER HEATER
The positives exceed the negatives by a wide margin; yet, there are still some considerations to make:
- Installation costs: As with any technological change, there will be some initial out-of-pocket expenses when switching to a tankless water heater, both for the water heater itself and for the installation. Additionally, tankless water heaters may necessitate the construction of new venting and gas lines as part of the installation process. The higher expenditures, on the other hand, begin to be recouped immediately after installation, thanks to the energy savings realized by not having to regularly reheat water in a tank. The amount of water produced: While a 60-gallon tank loaded with hot water is unquestionably wasteful, it is also obviously practical, especially when your household’s demands include showering, doing laundry, and running a dishwasher all at the same time. Even though a tankless water heater is more energy efficient, its output is also more restricted, which is why it may make sense to install more than one in your house – or even more than one in your business. In addition to a choice of types to suit your requirements and lifestyle, Reliance now provides an energy-efficient recirculating unit that may help you save money on water bills.
Rent or buy?
If you decide to make the transition to a tankless water heater, you’ll need to determine whether you’d want to rent or own the unit. When you purchase a water heater, you will incur one-time charges but will not be charged rental fees, and you will be responsible for the costs of maintenance and repairs. Choosing to rent from Reliance Home ComfortTM allows you to take advantage of a Water Heater Rental plan, which includes free basic installation as well as long-term protection for a low monthly fee.

Tankless Water Heaters: A Buyer’s Guide
According to The Home Depot
What is a Tankless Water Heater
Because they heat the water immediately, tankless water heaters take up far less space than storage water heaters. As soon as you switch on the hot water, cold water is sent down a pipe and into the tankless water heater unit, where it is heated by either a gas burner or an electric element. This ensures that you have a continuous supply of hot water. On average, tankless water heaters can produce 2 to 5 gallons of hot water every minute, according to the manufacturer. According to energy.gov, gas-fired tankless water heaters are capable of producing greater flow rates than electric counterparts.
When you have a big family who uses a lot of hot water, it is typical to have more than one tankless water heater installed. Having adequate hot water accessible for showers, washing, and the dishwasher will guarantee that there is always enough to go around.
Tankless Water Heater Advantages
Compared to traditional tank-style water heaters, tankless water heaters (also known as “on demand” units or instant hot water heaters) consume 30 to 50 percent less energy, resulting in annual savings of $100 or more for a normal family, depending on water usage.
- These devices only heat water when you turn on the faucet
- Otherwise, they do not. These engines are often powered by natural gas or propane. Most significantly, they reduce the additional cost of maintaining 40 to 50 gallons of hot water in a storage tank, resulting in less energy loss. Another advantage is that they are more environmentally friendly. Aside from that, they provide a constant flow of hot water, which is perfect for filling a large hot tub or whirlpool
- And They are more compact than a normal water heater and may be mounted on a wall
- They are energy efficient.

Tankless Water Heater Disadvantages
- The most significant downside of on-demand or instantaneous hot water heaters is their high initial cost. The smaller units that are frequently seen will not be able to provide enough hot water to meet the needs of most families. They can only handle one faucet at a time, which is an issue if you want to take a shower while the dishwasher is in the dishwasher. It is possible to purchase larger apartments that can accommodate the needs of an entire family, but they are more expensive. Tankless units, on the other hand, feature high-powered burners, which necessitates the usage of proper ventilation (a dedicated, sealed vent system, which requiresprofessional installation). Natural gas burners sometimes necessitate the use of bigger diameter gas pipes, which increases the cost of installation.

Electric vs Gas Tankless Water Heaters
One of the most significant distinctions between electric tankless water heaters and gas tankless water heaters is their energy-efficient design. Electric tankless water heaters normally have an efficiency of 98 percent or above, but gas tankless water heaters often have an efficiency of 80-85 percent or less. A gas tankless water heater can be less expensive to operate and will likely last longer than an electric tankless water heater. Tankless water heaters will free up valuable floor space that would otherwise be taken up by a large, cumbersome water heater.
A complete home electric tankless water heater may consume more than 25,000 watts of power, whereas a traditional water heater consumes just 5,000 watts of electricity.
Gas Tankless Water Heaters
Most importantly, the efficiency of electric tankless water heaters and gas tankless water heaters is the most significant difference between both. Electric tankless water heaters normally have an efficiency of 98 percent or more, but gas tankless water heaters typically have an efficiency of 80 to 85 percent. Tankless water heaters that run on natural gas can be more cost-effective to operate and last longer than other types of water heaters. It is possible to save space by using a tankless water heater instead of a traditional tanked water heater.
A whole-house electric tankless water heater may consume more than 25,000 watts of power, whereas a traditional water heater consumes just 5,000 watts of electricity.
The Bottom Line: Pricing and Installation
When you’re putting together a quote for a unit, make sure to include installation fees in the estimate or firm offer. You cannot do this assignment on your own unless you have professional-level expertise. Many home shops and plumbing specialist businesses have the greatest tankless water heaters on the market.

How Tankless Water Heaters Work
If you’re thinking about making the move to a tankless water heater, you should carefully analyze the advantages and disadvantages first. Benefits:
- The majority of tankless units qualify for a $300 federal tax credit. They never have a shortage of hot water. They have a five- to ten-year lifespan compared to tank heaters. They are more energy efficient since there is no standby heat loss. Their compact design allows them to be put on walls or outside with an anti-freeze kit, saving valuable floor space. Smaller units can be positioned behind cabinets or in a closet to be closer to the point of usage
- Larger units can be installed on the roof. They simply require enough electricity to heat the amount of water that is required at any particular time. You may save as much as 20% on your water heating expense by following these simple steps. Electric vehicles do not emit greenhouse gases
- Thus, they are environmentally friendly. The majority of devices are controlled by a remote control and may be configured in up to four different ways. Because of the burst tank, there is no risk of flooding.
- They can be as much as three times as expensive as a tank water heater. It is distributed throughout all of your household fittings to distribute your hot water output. It is possible that you may need to install a bigger natural gas line in order to adequately feed the device. In order to vent gas and propane units, costly stainless steel tubing is required. Electric models may necessitate the installation of an extra circuit. Units fuelled by natural gas emit greenhouse emissions. Annual service is required for gas units, which adds to the overall cost. Electric models consume a great deal of energy. It is necessary to have a minimum flow rate of.5 GPM in order for the heat exchanger to function properly. Because of the lag time, you may have to run your water for longer periods of time in order to get to the hot water, increasing water waste.
Other Points to Consider:
- There are a few other points to consider:
You may determine whether or not converting to a tankless water heater will save you money in the long run by comparing the yellow “Energy Guide” stickers on your present water heater with the yellow “Energy Guide” stickers on the tankless model that best meets your needs and wants.
