Benefits of a Tankless Water Heater
The number one reason you’d want to install a tankless heater in your home is cut down energy bills. Tankless units can help you save up to 40% on your monthly utility bill. Now, that’s more than 30% efficiency in comparison to a tanked water heater.
Other than being healthy for your wallet, tankless water heaters bring forth a myriad of benefits including;
You’ll Never Run Out of Hot Water
Tankless water heaters, by design, are on-demand heaters. In essence, this means that they’ll provide you with hot water whenever you need it. Think of them as heaters that allow you to enjoy the hot water at the press of a button.
Besides, you’ll never experience standby heat loss with these models. It is also worth noting that these heaters only require enough power to heat the amount of water needed at any given moment.
Is your old tanked water heater nearing the end of its lifespan? Well, a standard tankless water heater will last you five to ten years longer compared to a tanked version. While most tankless models are high-end with high-end prices, the durability, by extension offers value for your money in the long run.
One of the major differences between tankless and tanked water heaters is that you don’t need a lot of space to mount the former. In fact, a tankless water heater should save you space and offer multiple placements on your wall. Most models that we’ve reviewed above offer indoor and outdoor installation complete with an anti-freeze kit. You can even opt for a smaller unit that can fit under your cabinet or closet for closer point of use.
Gas tankless water heaters have near zero emissions and are, therefore, safe for the environment. Most gas-powered models use low NOx technology to keep emissions as low as possible. Even the electric tankless water heaters don’t generate harmful greenhouse gas. Moreover, these heaters come with innovative features to prevent scalding water from reaching your showerhead or faucet.
Easy to Operate
It doesn’t require a lot of knowledge to operate a tankless water heater. The hardest part of using these models is installation. Once you’ve mounted yours all you need to do is to set the temperature on the unit’s dial and you’re good to go. You may even choose a model that supports remote control for hands-free operation.
No Possibility of Flooding
Unlike tanked heaters, you’ll never have to worry about possible flooding caused by a ruptured tank. This goes back to the point that tankless heaters are safe for you and your household. Speaking of safety, some models come with an integrated system that detects internal faults as they occur and give you a warning in advance.
See? There’s indeed more than one reason you should purchase a tankless water heater. The only thing you should remember is to check the flow rate of the unit you plan to get before spending your money on it. At the end of the day, you want a model that can handle your hot water needs, whether it is for residential or commercial applications. Note – We will explain about water flow and why it is important in greater detail in our buyer’s guide below.
How Does a Tankless Water Heater Work?
In order to make the most out of your tankless water heater, you must understand how it operates. But before then, let’s start by breaking down how a tanked water heater works. The traditional heater system has a large tank that holds and heats the water. To give you hot water, the tank heats continually to ensure that the water stays at a constant temperature. The energy needed to keep the water hot when you’re not using it is known as standby heat loss.
Tankless water heaters, on the other hand, only heat the water when you need it, which means that there’s no standby heat loss. In fact, it is the lack of standby heat loss that makes tankless heaters more efficient.
The Heat Exchanger
A tankless water heater uses a heat exchanger to increase the water’s temperature. A heat exchanger is a device that works by transferring heat from one source to another and is common in car radiators, air conditioners, and refrigerators. In this scenario, the incoming flow of water activates the heat exchanger. In other words, when you turn on your hot water tap, it triggers the incoming water to circulate through the exchanger which in turns heats the water at your preferred temperature.
The Lag Time
Tankless water heaters are available in two options; whole house and point of use heaters. Whole house heaters are typically large, costlier and can work with more than one outlet at any given time. Point-of-use heaters, however, are small with the capacity to heat one or two outlets. Due to their size, they can fit in your closet or under a cabinet.
One benefit of this type of heater is that you can install it close to your water outlet to avoid water loss caused by lag time (the amount of time it takes for your water to reach to the faucet). In big households, the lag time can run up to several minutes. Theoretically, this means that while your utility bill may be going down, your water consumption will be going up. So, consider pondering about the lag time and how it affects your budget before deciding to go tankless.
As you may have already figured out, tankless water heaters come in either electric, natural gas or propane models. Almost every other point of use unit on the market is electric. Whole house models are natural or propane powered. Of course, the model you go with and the heating source that best works for you depend on a host of factors. Again, we shall look at these factors in our buyer’s guide that’s coming right up.
How to Choose the Best Tankless Water Heater [2020 Buyers Guide]
While you may read water heater reviews to determine which the best model to choose is, it goes deeper than that. The thing is, tankless water heaters are expensive, and you can’t afford to make an error when selecting one for your household. What follows is a compilation of the most important considerations to make.
The Energy Efficiency
As stated, one of the benefits of going tankless is the energy efficiency these heaters have to offer. It, therefore, makes perfect sense to weigh how much the model you intend to purchase will save you in terms of utility bills. So, be sure to look at the Energy Factor (EF) before buying as it determines the overall efficiency. The higher the EF, the more efficient the water heater is.
Even then, a high EF doesn’t necessarily translate to lower operating costs. Electric systems, for instance, have a higher EF in comparison to their gas counterparts. But, because gas is relatively cheaper, they tend to offer a lower annual operating cost. Here’s a practical example.
A gas-powered heater can give you a 70 degrees Fahrenheit temperature rise if it has a flow rate of 5 gallons per minute. However, an electric model will only deliver up to 2 gallons per minute for the same temperature rise.
Of course, you can only invest in a specific tankless water heater if it can meet your needs. You have, therefore, to examine the model’s temperature rise and the flow rate. At the very least, you should expect your tankless water heater to deliver anywhere between 2 to 5 gallons of hot water every minute. And as we’ve seen, gas-powered water heaters can provide a higher flow rate in comparison to electric systems. To be safe, confine yourself to finding a unit with a flow rate of 8 gallons per minute. Better yet, you can use the following guidelines.
- Bathroom faucet: 3.0 – 5.0 gallons per minute
- Shower: 1992 4.0 – 8.0 gallons per minute
- Kitchen faucet: 3.0 – 7.0 gallons per minute
Also, keep in mind other appliances that you may need to use such as washing machines and dishwashers. Other than that, you need to calculate the temperature rise to make sure that you’re selecting the right model. To do so, deduct the temperature of the incoming underground water from your preferred hot water output temperature.
Let’s say the incoming water temperate is 50 degrees Fahrenheit, and you set your output temperature at 120 degrees Fahrenheit. In such a case, you need to choose a tankless unit that can heat the incoming water at a temperature of 70 degrees to reach your desired temperature of 120 degrees. You should remember that the temperature rise will keep fluctuating throughout the seasons, all-round the year. Plus, the temperature of the incoming water will have an impact on the flow rate and speed of your heater.
The Fuel Type
This is indeed a critical decision to make when shopping for a water heater. The best on demand water heaters should offer a continuous flow of hot water while helping bring down your energy costs. By now, you know that there three fuel types to choose from; electricity, propane, and gas. The fuel available in your area of residence determines the type of tankless water heater that you select. It is always important to compare the cost of each fuel type before making your decision.
…Other Equally Important Considerations
The Fuel Supply Line -Your line of fuel supply has to be sized to provide the power needed to deliver instant water whenever you need it. Most gas tankless heaters have an output of about 200,000 BTU.
Ignition –There are three types of ignition systems. Expensive models have a complex ignition system in comparison to cheaper units. It is worth noting that the simpler the ignition system, the less the savings the heater will claim.
Venting – Gas tankless heaters require venting for proper functioning. While you can let the vents run through the rough horizontally, you’re better off picking a unit that supports category III venting for better combustion. Even then, it is essential to note that you’ll ONLY require venting if you pick and indoor gas tankless water heater.
Lastly, if you decide to go with an outdoor gas tankless water heater, you should make sure that it’s robust enough to endure the beating of weather elements. Select a model that features an anti-freeze kit.
Frequently Asked Questions
And now, we list down the most commonly asked question in regards to tankless water heaters.
Is it possible to replace my existing tanked water heater with a tankless option?
Yes, it is very much possible. However, we must mention that you have to address some specific requirements before you can go tankless. First of all, you have to know that gas heaters (if you decide to go that route) require a special vent pipe. You’ll also need to have access to a stable gas supply line that will not only feed your water heater but also other appliances connected to that gas pipe. If you invest in an electric water heater, you will need a bigger gauge wire and breakers than the ones you’re currently using with your tanked water heater.
Is it safe to install a tankless water heater in my attic?
Okay, to begin with, it is impossible to give a definite yes or no answer to this question without seeing your plumbing piping. Nonetheless, before you decide to install mount a tankless water heater in your attic, you must be sure that you will not create a possible water siphoning condition. This is because your heater should not have air in the lines. Water siphoning, irrespective of the type of heater you are using may damage your system when there is not enough water in the lines.
I would like to install a tankless water heater in my vacation cabin or home. Is it possible to drain all the water when I’m not using the system to prevent freeze damage?
Yes, it is possible with most models. However, we recommend that you check with the manufacturer just to be sure. If you are given a green light to drain it, all you need to do is to empty both lines to and from your heater. Keep in mind that as long as there are no check valves, that is enough to drain all the water. And, just to be sure that there is no water in the heater we suggest that you empty in two halves. One before and after the unit – you should also consider blowing air through your water heater.
Is it advisable to install my own tankless water heater?
Well, in most cases, we wouldn’t recommend that you install your tankless water heater. In fact, almost all the time, the local plumbing code doesn’t allow you to do so. It may also interfere with the warranty and that is something you don’t want to do. Other than that, there’s every possibility that you might damage your heater even when you have the experience.
You see, most houses don’t have the required electrical configuration for safety and best performance. Besides, you may have to install 240-volt wiring. And, unless you’re replacing a gas-powered tankless water heater, you will also need gas lines and a gas meter for the upgrade. We’ve not even mentioned the venting requirements with most gas tankless water heaters and the actual plumbing that goes into mounting the unit. In short, when it comes to installing a tankless water heater, you’re better off hiring a professional.
I read that you cannot install some tankless water heaters in certain areas. How true is that?
Yes, there are some states and cities that don’t permit the installation of specific models of tankless water heaters for various reasons. It is therefore essential that you check with your local authorities before ordering for your heater.
Note – particular heaters such as 3-phase or de-ionized heaters don’t come with a return policy. The last thing that you want is to get stuck with a heater that you can’t return or one you can’t install due to local code restrictions.
Why don’t any of my tankless water heaters show the first-hour rating?
Tanked water heaters show the first-hour rating. The amount of hot water the heater can generate in an hour when the tank is full typically determines the first-hour rating. The case is different when it comes to tankless water heaters. You see, a tankless option doesn’t start with a tank of hot water, so it is not practical to expect it to have a first-hour rating as is the case with the tank option. What you get with tankless water heaters is the gallons per hour rating. The number of gallons per hour that the heater can generate when you raise the temperature of the incoming water determines the flow rate.
Which is the best temperature to heat my incoming underground water?
Well, this is a personal question because the opinion of how hot the water should be may vary from one person to the other. You should also consider that the temperature of the incoming water may different at various times of the year. Even then, a lot of studies have tried to determine what most people find comfortable, on average.
Based on these studies, we can throw in the numbers to help you to narrow down the possibilities. According to research, most people are comfortable washing their hands at near body temperature. You’re likely to walk into a shower that spurts water at a temperature of anywhere between 90 to 110 degrees Fahrenheit, primarily depending on whether you prefer a hot or cold shower. Almost everyone agrees that 58 degrees Fahrenheit is too cold for comfortable hand washing leave alone showering.
Exactly how much will a tankless water heater save me?
First of all, there is no dispute that going tankless will indeed save you money. The specific amount, however, depends on a number of factors. The cost of natural gas or propane, for instance, will determine how much money you end up saving. You may have to pay a more if you use lots of hot water. One thing remains clear though; you will never run out of hot water. And the best part is that you are totally in control of the temperature at which your unit heats the water.
How long will my tankless water heater last?
Tankless water heaters will last you long enough to return the value for your money. The type of installation and usage may also have a hand in the life expectancy of your heater. In general, most models on the market will last anywhere between 15 to 25 years. As long as you’re using quality water and the installation is on point, your model shouldn’t have a problem lasting for more than two decades.
There’s a catch though, even the best tankless water heaters require regular maintenance to stand the test of time. You have to clean yours on a regular basis to remove scale deposits and so on. If you have an outdoor gas tankless water heater, you should ensure that you install it in a place where it’s relatively safe from weather elements such as snow and heavy rainfall. Latest models come with a self-regulating internal mechanism that alerts you about any malfunctioning which also helps increase the durability.
Tankless water heaters have their place, now and in the future. With the world shifting to green and sustainable energy, it is almost impossible to imagine that tankless water heater will become obsolete. The best part is the fact that these units not only heat the water relatively fast but also do so without using a lot of energy which means more money in your pocket. And hey, who wouldn’t like to make some savings, especially if it is on recurring bills such as utility? The point that we are trying to make here is that you’re better off getting a tankless water heater, now more than any other time.
As is the case with any home appliances though, you have to shop right. Add the fact that most tankless water heaters don’t come cheap means that you have every reason to exercise due diligence before splurging. After all, you want to be sure that you are investing in a model that will indeed meet your hot water needs for years to come.
