In our top ten product reviews and descriptions section, we have highlighted some core features of each of the products. However, we haven’t talked about the features in detail and what buyers, both new and experienced, should know before they make a choice. Stay tuned to know more about tankless water heaters, their core features, and the benefits of getting one.

Are Tankless Water Heaters A Worthy Investment?

The idea behind the creation of tankless water heaters was to bring an end to the common household water wastage issues in modern homes. These heaters generate hot water on demand and can save you up to 50 percent on energy costs. Ever since these units came into existence sometime in the 1990s, they have not only grown in popularity but also became more sophisticated.

The modern versions of tankless water heaters boast of advanced features like wireless connectivity, built-in recirculating pumps, and less hectic control and maintenance features. There’s definitely a perfect tankless water heater for everyone, and here is why you should get one.

Instant water heaters heat and dispense water on demand. They achieve optimal water conservation by eliminating the need for storage tanks, which are prone to leaks.

That makes them not compact enough to fit well in modern homes. Instant water heaters are as big as a suitcase, so you can conveniently hang them anywhere in your house.

3. Can Be Winterized Easily

Draining the tank of a water heater has proven to be one of the most challenging things vacation homeowners have to deal with regularly. It takes time and requires you to be very careful. Draining a tankless water heater takes a few minutes, and it is way easier and fun.

4. Instant Water Heaters Are Safe

Tankless water heaters contain no storage tanks, and so issues with leaks and water spills aren’t common. The exhaust and air-supply vents of instant water tanks are durably sealed, and so, no issues with carbon monoxide leaking into the unit owing to back-drafting.

Features To Pay Attention To When Buying Instant Water Heaters

Alongside your personal preferences and budget, there are things you cannot neglect when shopping for instant water heaters.

1. The Flow Rates

The reason you’re investing in a tankless water heater is to minimize energy bills and enjoy quality access to hot water when you want. And to achieve the best results, you must determine the flow rates of all the appliances that will connect to the instant water heater.

These are the average flow rates and temperatures of different appliances to help you choose the right choice of a water heater.

• Kitchen Sinks – the estimated average flow rate of kitchen sinks is 1.5 GPM at an averaged hot water temperature of 110 degrees.
• Bathtubs – bathtubs have an averaged hot water flow rate of 4 GPM at an average temperature of 102 degrees.
• Dishwashers – these are estimated to have a flow rate of 2 GPM at an average temperature of 120 degrees.
• Showers – showers have averaged flow rates of 2.5 GMP and hot water temperatures of 104 degrees.
• Washing machines – these are known to have averaged flow rate of 1.5 GMP and a hot water temperature of 110 degrees.

You’ve to know the amount of water and at which temperatures the appliances you have in place use hot water so you can decide which instant water heater has the most compatible hot water flow rate. If your fixtures are a bit large and aged, consider getting tankless water heaters with larger flow rate figures.

Consider heaters with a lower flow rate if your fixtures are smaller and more advanced. In case you don’t know how old the version of the fixtures you have at home is, you should consider heaters with a higher flow rate.

2. Decide Which Power Source Is Ideal For You

Tankless water heaters are either gas, solar, or electrically-powered. Whichever you choose, here is what you should know.

• Electric Instant Water Heaters

Almost 40 percent of tankless water heaters are electrically powered. Electrically powered instant water heaters boast amazing energy efficiency rates, though they are only ideal for homes that are connected to electric power grids. They eat up minimal space as they can comfortably fit anywhere in your house. It costs cheaper, installing electrically-powered water heaters if your home is already wired for electric water heaters.

Unfortunately, electric heaters aren’t powerful enough to be installed in larger families. They aren’t perfect for whole-house applications because it costs more to upgrade them. Larger families that opt for electric instant water heaters will be forced to install several units to ensure enough and continuous water hot water supply. When buying an electric tankless water heater, you must check things like the voltage, amperage, and circuit breakers.

• Gas Powered Instant Water Heaters

Gas-powered tankless water heaters are the most powerful units you can find in the market today. They are fit for larger families and commercial installations. If your house isn’t wired for electric heaters, the gas water heaters will be the perfect deal for you.

These types of instant water heaters are way costlier. They are more durable and reliable, though. Based on the U.S. Department of Energy, liquid propane and natural gas tankless water heaters can save you up to $100 annually, while the electric counterparts can only save you $40 on energy bills annually.

In buying gas tankless water heaters, you have to choose from the three ignition options, which are standing pilot light, direct, and hydro-power ignitions. You must as well choose between direct venting and power venting options.

• Solar Powered Tankless Water Heaters

The need to make the world environmentally conscious has motivated some water heater manufacturers to create units that can tap solar power to ignite their water heating functions. Most solar instant water heaters are installed on the rooftop so they can efficiently tap and convert the sun rays into useful energy that would later be used to heat cold water.

Solar water heaters are the most costly choices, which require more extensive maintenance. The best thing about solar heaters is that they offer long-lasting service with lower ownership costs.

3. Type of Tankless Water Heater

We’ve three main types of tankless water heaters. These depend on the heating technology used as well as the equipment sophistication. The three main options are non-condensing, condensing, and hybrid condensing.

• Non-Condensing Tankless Heaters

The non-condensing units use the original technology and novelty of the first-generation tankless water heaters, which were discovered in Europe and Japan. They have been in use for several decades now. The non-condensing tankless water heaters have a heat exchanger that heats the hot and boasts an Efficiency Factor of .82 to .85.

These types of instant water heaters are tested and confirmed to have unequaled reliability and performance. The only problem with these tankless water heaters is that they have hot exhaust, and so you must install costly stainless-steel venting.

• Condensing Water Heaters

These fall under the second-generation tankless water heaters that use two heat exchangers and an exhaust. The use of more heat exchangers and cooler exhaust to heat the water result in better efficiency of up to 94 percent. As with these instant water heaters, they can be vented using cheaper PVC. They have lower efficiency rates and cost more, though.

• Condensing Hybrid

The third-generation tankless water heaters, also known as condensing hybrid, were originally manufactured in the United States. These advanced and more sophisticated tankless water heaters have a small water holding tank, with a capacity of one to two liters.

The small water tanks work to maintain a hot water reservoir and eliminates issues with lower efficiency. They can realize the required real-life efficiency of .92 to .96. Based on a study by the Gas Technology Institute, the condensing hybrid instant water heaters operate at a high efficiency of 94 percent and experience lower degradation owing to short draws.

4. The Intended Application

Currently, every model or brand of tankless water heater comes with features and competences fit for handling different applications smoothly. Most of the heaters come with labels highlighting what they can efficiently do. These are the main tankless water heater models and their core applications.

• Single point water heaters – these tankless water heaters are only capable of working with one electric fixture. They can be installed under the sink or close to dishwasher, depending on personal preferences.
• Thermostatic – these types of tankless water heaters work as boosters for temperature losses caused by sanitation, long pipe runs, and dishwashers. These units are perfect for installations in hospitals, schools, and laboratories where accurate temperature control is required.
• Whole house indoor models – these smart and powerful tankless water heaters work best where there are multiple points and are ideal for serving your entire house, cabin, condo, and apartment.
• Whole house outdoor models – these are perfect for bigger houses, and work best for the whole apartment, condo, or house where there are multiple points of use.

5. Reviews And Ratings

Every competition must produce a winner and a loser. In the competition for the best tankless water heaters, you will discover some products that outperform others in terms of functionality, sophistication, reliability, and durability. You want to buy and install a water heater that won’t disappoint you later, and so the least you can do is to evaluate and compare tankless water heater reviews and ratings carefully.

Almost all high-quality and energy-efficient instant water heaters that are designed to give optimum value for money will have hundreds of positive testimonials and good ratings alongside few criticisms from the unsatisfied clients.

You very well know as I do that nothing in this world regardless of how good and reliable it proves, will lack criticisms. And that’s why you should also be wary when evaluating tankless heaters that have no negative client testimonials. There are only two instances a product will have no negative reviews.

One is when the manufacturer or supplier deletes all the negative reviews, and the second is when people who have never used such products are paid to write manipulated customer reviews. Manipulated client testimonials are very easy to detect since they only tell one side of the story—which is the benefits you will get from the product.

6. Manufacturer Warranties And After-Sales Services

One area top brands and manufacturers triumph in is creating high-quality and durable products that meet customer quality expectations. Because they trust in the superiority of their creations, they always offer them alongside long-standing warranties and guarantees. Most of the top tankless water heater brands give one year of the unit body warranty and five years of heating element warranty. Besides the warranties, the top brands will offer the best after-sales services.

The lifespan of most tankless water heaters is estimated to be slightly higher than 20 years, but a lot can happen along the way, rendering the units useless. For that reason, ensure to get value for money by investing in heaters that have long-lasting warranties. Have a look at the customer complaints, and if you notice that most of them point to the direction of the product suppliers or manufacturers not honoring their warranty promises, you keep off buying such products.

7. Sophistication And Features

It’s the era of advanced technology and smart home integrations. Who doesn’t love the convenience of being able to control their appliances while miles away from home? What about the simplicity of being able to automate the functions of different appliances?

Nobody doesn’t love simplicity and convenience when it comes to running household appliances. Besides making sure your tankless water heater performs to your expectations and has the necessary amenities, you have to look out for advanced features.

Look out for sophisticated features like thermistor control valves and temperature display that add to the convenience and simplicity of operating tankless water heaters. If you want to integrate the water heater into your smart home system, consider getting one with Wi-Fi connectivity.

Keep your energy consumption rates low by opting for a unit with a self-modulating function. The self-modulation function works by adjusting energy levels, depending on your preferred temperature settings and volume of water used.

8. Durability And User-Friendliness

If there is anything tankless water buyers cannot take for granted is the durability of their selected products. Who wants to dash money to a product supplier after they are promised the best only to receive a nicely packaged piece of crap?

I am sure everyone wants to get value from every purchase. Thus, the least you want when buying an instant water heater is to get a product that will lose its value in weeks or even months.

Durably designed water heaters are going to bring a smile to your face because they will last for years, ensuring you optimally make the most of your investment. Top water heater brands have a long-life and will guarantee you of impressive performance for years. It’s good you search for a heater with a decent mechanism. It should be a machine whose spare parts are readily available in the market.

The user-friendliness of the tankless water heater is an important consideration, too. All a tankless water heater buyer wants is a product that’s easy and fun to operate. If a product cannot fulfill that simple obligation, its production is not worth it.

With a user-friendly tankless water heater, you’ll have a convenient and accessible product that performs to your expectations. Don’t be in a hurry to choose a water heater before you have confirmed the features and qualities that make it handy, accessible, and user-friendly.

9. Energy Consumption Rates

Adding a water heater to your household will definitely increase the power bills. That’s because it an electric equipment and will need the power to operate. But that doesn’t mean that it should sprout out the power bill so high such that you will regret ever investing in a tankless water heater.

To choose a tankless water heater that won’t raise your energy bills, ensure you first check the volume of water used in your household. These water heaters heat water on demand, and the more hours they stay active, the more energy consumed. If your household water consumption rates are quite high, consider settling for the most efficient water heater in the market to keep your energy bills under control.

In determining what water heater to buy, consider the temperature of the input water, as well. The input water in cold places will be colder, and so more energy will be used to heat the water to the desired temperature. Consider the temperature preference of the output water by users, also.

Get water dispensed at the desired temperatures without raising your energy bills by investing in tankless water heaters with external controls and thermostat temperature functions.

10. Ease Of Installation

Tankless water heaters are simply easy and fun to install. You virtually can hang these water heaters anywhere in your house and get everything working in minutes. However, that’s not always the case with all types and brands of water heaters. Some are a bit technical and require a high level of plumbing and wiring skills.

With most instant water heaters, all you should do is to place your unit on your desired wall surface, hook the output and input pipes securely, run water via the system to remove any accumulated air, install the needed circuit breakers, hook up the electric wires as per the user manual and then activate it for use.

When dealing with more sophisticated water heaters, the installation process may be a bit complex and demanding, though. Read the user manual carefully to know how to go about the on-demand water installation process. You may have to check with other customers to know how their installation experiences were. Because you don’t want to damage your appliance during the installation process, it is good you inquired about the installation complexities and demands beforehand.

11. Construction And Materials

There is an extensive range of materials used in creating electric tankless water heaters. The largest number of water heater brands and manufacturers use metals to create their products. Metals are naturally prone to limescale accumulation and would always need regular annual maintenance to stay strong and up to the task.

That doesn’t mean all sophisticated and advanced on-demand water heaters are made of metals. Some use stronger and more versatile materials alongside advanced construction technologies such as infrared. The appliances that employ infrared construction technology require less maintenance and accumulate less amount of scale.

They are way more durable and flexible and will serve you longer. The durability of such units is unquestionable, and their performance will surely woo you. For that reason, when buying electric on-demand water heaters, you must check the build quality and the materials used. It would be better you read the product descriptions to understand how it’s constructed and the materials used.

12. The Maintenance Costs

The cost of maintaining the advanced versions of on-demand water heaters that employ the latest design technologies is a bit high. Experts have estimated the maintenance cost at around $600 a year, which is surely high. The maintenance caters to everything, including general cleaning, care, repairs, and upgrades.

With regular in-depth cleaning, which involves flushing out all the units to clean off all the accumulated sediments and minerals, you’re sure to keep your appliance at a peak performance state. Regular cleaning and maintenance should be done to boost the appliance’s performance as well as keep it safe from potential more costly damages. Don’t ever forget that costly damages that require more technical spare parts can end up voiding the warranty.

The high cost of tankless water heaters is a burden itself, and so you wouldn’t want to add another financial burden to your life in terms of costly regular maintenance. Consider getting a high-quality heater from trusted brands and manufacturers to avoid common issues with costly annual maintenance costs.

13. The Heating Costs

You should as well consider the heating costs of the electric tankless water heater you are about to buy. You already have enough energy bills to pay, and even if you were to add them, you wouldn’t wish to raise them by 20% or 30%.

Replacing the electric tank water heater in your household with a tankless unit can save your home significantly in terms of energy costs. These units are designed to heat water only when the demand arises. They won’t heat water that’s not needed, hence won’t consume unnecessary energy to make your energy bills sprout extremely high.

All tankless water heaters don’t use the same heating technology. The costs of operating these units will differ from one brand to the other. Research the energy efficiency ratings of the water heating appliance you want to buy, and make sure you settle for one with the best energy efficiency ratings.

14. Brand And Manufacturer

It’s a common habit among product buyers to look out to the most trending and trusted water heater manufacturers for high-end and quality products. That’s because once a brand or manufacturer attracts the attention of different customers, it becomes hard for the customers to shift their loyalty unless the manufacturer gets out of business or starts creating low-quality products.

In regard to this same reason, you must be specific when it comes to the brand and manufacturer you trust to be your primary source for electric tankless water heaters. You want a brand that can be trusted and has established its reputation in the industry.

In our top ten product review section, we have outlined and reviewed the top-selling products from the best brands and manufacturers in the world. If you want the best tankless water heaters for your needs, you may need to search for products from the manufacturers behind the innovative and reliable water heaters we just outlined.

15. The Climate In Your Residence

As said earlier, electric instant water heaters heat water when it’s needed. They do have different power ratings and can effectively heat water to certain levels. The ability of an instant water heater to heat water to the desired temperature is usually affected by the temperature in the area you live in.

If you live in extremely cold areas, an ordinary water heater with basic features may not be the perfect choice for you. That’s because if it can only heat water by up to 40 degrees, it won’t make the water hot enough for your desired applications.

In cold areas, water temperature is extremely low. Let’s say the temperature is 50 degrees, and the heater can only heat it by 40 degrees, you will end getting partially cold water. To enjoy using hot water on demand while living in cold places, you are advised to settle for more powerful units that can heat water by up to 70 degrees as they will make your input water hot enough for the desired applications.
