Choosing a new water heater is important. Water heaters consume a lot of household energy. The right water heater can make a big impact on energy efficiency in your home. When deciding which of the different types of hot water heaters will work best for your home, there are many things to consider.
Tankless electric water heaters are also called instantaneous or on-demand water heaters. Rather than use a storage tank, the water circulates through a heating element that heats the water as needed. Tankless water heaters are rated by the gallons per minute they provide, and the average life span is 20 to 25 years.
How you plan on using a water heater determines how much hot water it needs to supply, as well as whether you need a single unit, individual units at several points in the house or a combination of solutions.
In a tankless water heater electric, the capacity is measured by flow rate, calculated in gallons per minute. Getting the correct size of tankless heater requires figuring out how much hot water you may need at any given time, coming up with a flow rate number and then matching that figure to the measure on a given system.
Tankless water heater tips to consider
- Overheat protection: Keeps the water from overheating in the system by cutting off the power supply once the set temperature is reached.
- Digital display: Makes it easier to monitor the temperature and make precise adjustments.
- Automatic constant temperature: A stable water temperature is a great help to protect your skin, and also get the better experience for using hot water.
- Leakage protection: Provide an important safeguard for your family life.

Electric or gas? Which is better? In reality, there is no single answer to this question. The following factors all play a role in choosing what type of tankless water heater is best for your needs:
1.Efficiency / Operating Cost: While gas tankless water heaters are certainly more efficient than their tank cousins, their efficiency usually peaks at 80-85%. Conversely, most electric tankless water heaters are 98+% efficient. electricity costs are more stable and projected to rise much slower than gas rates in future.
2.Installation: Gas tankless water heaters have complex venting and combustion air supply requirements, especially when installed in a confined space, is that these requirements can make installation very expensive. Electric tankless water heaters are very small, and they can be installed in a closet, under a sink, in a crawl space, or a wide range of other areas where a traditional tank or gas tankless cannot. the installation of an electric tankless water heater is generally much cheaper than the installation of a gas tankless water heater.
3.Maintenance, Service Life and Warranty: Electric tankless water heaters require very little maintenance. In fact, other than cleaning the inlet screen filter occasionally. On the other hand, gas tankless heaters should be inspected annually by a trained technician to ensure safe fuel combustion and performance.
4.Environmental Impact: Electric water heater is no greenhouse gas emissions, small size reduces environmental footprint in manufacturing and ultimate disposal - future electricity generation to come from green sources such as solar, wind, and wave energy, gas water heater produces greenhouse gases and increases reliance on fossil fuels

If you want to enjoy a hot bath without hindrance, I would highly recommend using tankless electric water heater. Hot water is always available, no waiting, and no need to preheating .
You many have a question: Do tankless water heaters use more water than traditional tank water heaters? The answer is : NO . Tankless electric water heaters heat water as needed rather than keeping it in a tank until it is needed. A traditional water heater must constantly turn on and off to keep water warm and ready to go because once water sits in a tank, it starts to lose heat. Water is more energy- efficient and water save with tankless because it is heated quickly and only when necessary.

Tankless water heaters are becoming more widespread and the right choice for more people and more properties now. Compared to tank water heaters, tankless water heaters have a longer lifespan, lower operating costs, and a number of other benefits. But how do you know if a tankless water heater is right for you – and if it’s worth the investment?
1. Your Old Water Heater Is Wearing Out
As a water heater gets older, it becomes less efficient. The heating elements and other parts of the heater can get clogged with grime and corrosion, leading to higher heating costs, and poor performance. If your old water heater is wearing out, you may want to consider foregoing the traditional, tank-based water heater in favor of a tankless model. Because you’ll be purchasing a new unit anyway, this is the perfect time to make the switch!
2. You Want To Lower Your Monthly Energy Bill
Instant hot water is delivered on-demand which nearly eliminates standby heat loss. Water flows through an advanced system of electric heating elements, which instantly heat it up the desired temperature. There is no need for the storage of hot water – which boost efficiency dramatically. Tank water heaters hold the water within a tank where it is heated and re-heated until needed. According to the US Department of Energy, a tankless water heater uses up to 34% less power to heat water. Moreover, based on the same study, electric tankless heaters bring in savings of about $44 per year.
3. You Constantly Run Out Of Hot Water
Tankless hot water heaters are rated to provide a certain number of gallons per minute (GPM) – this is the rate at which the heater can constantly heat and deliver hot water to appliances and faucets throughout your home. he chart below shows the range of water usage range and average water temperatures for various fixtures. We suggest using 2.5 gpm for a shower and 1.0 gpm for a bathroom as a reference point in determining your total simultaneous water needs.

One of our professional, JNOD will assess your unique needs, and recommend the type of water heater that would best meet your expectations and budget. Be sure to ask about special promotions!
Electric tankless water heaters require a large amount of electrical power (when running). Surprisingly so, they are very energy efficient and economic. We will look into exactly how much electricity does a tankless water heater use (by using the power equation P = I * V and cost equation Cost = kWh * t (h)).
Heating water is one of the most power-hungry processes. Tankless heaters heat up the water in seconds (5 seconds from cold to hot water). To achieve that, we need an incredible amount of electricity.
Does that mean that tankless heaters require a lot of electricity?
Yes and no. When they are ‘on’, electrical tankless heaters require up to 27,000W of electricity. For comparison, an average washing machine will require a bit more than 1,000W to run (and it will run for 1-2h). However, electric tankless water heaters are not running all the time. All this energy is used to heat up water only when we use hot water.
In fact, even according to the US Department Of Energy, tankless water heaters can significantly reduce monthly electricity bills:
“For homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters.” (DOE on energy efficiency of tankless water heaters)
Most households use less than 41 gallons of water per day. 24% – 34% is quite a lot of energy savings. Electricity-wise, tankless water heaters are a smart financial investment (they also last for 10-15 years).
But how can such a power-hungry appliance reduce the electricity bill?
It all comes down to how many amps does a tankless water heater draw (since the voltage is always the same: 220/240V). Let’s calculate a bit to see how much electricity does an on-demand tankless hot water heater use:
Calculating the maximum running costs of tankless water heaters is quite easy. The key information here is how many watts does a tankless water heater use. We’ll do one quick example here, with more to follow.
Example: You have a 20kW electric tankless heater. How much does it cost to run it?
Solution: 20 kW heater will spend 20 kWh worth of electricity if you run it for 1 hour. The average kWh price in the US is $0,1319. That means a 20kW tankless heater will spend, on average, 20 kWh x $0,1319 per kWh = $2,64 per running hour.
That doesn’t sound a lot, right? Obviously, there are many factors that come into play like intake water temperature, hot water demands, and so on. For a 20kW tankless water heater, the $2,64 per hour is the maximum electricity usage (running at 100% heating output). You will likely run your heater 100% output for the first 15 seconds, and then the heating output percentage (and hence water heater costs) drops.
Now, the real question is this:
How many hours per day do you run the tankless water heater? Here is how much it costs to run a 20kW electrical tankless heater from our example for different time periods:
* 20 kW running at 100% output for 10 minutes (shower): $0,66.
* 20 kW running at 100% output for 30 minutes: $1,32.
* 20 kW running at 100% output for 1 hour: $2,64.
* 20 kW running at 100% output for 2 hours: $5,28.
* 20 kW running at 100% output for 5 hours: $13,20.
Be aware that we always predispose:
1) Price of electricity to be $0,1319 per kilowatt-hour.
2) Power of heater is 20kW.
In this case you should replace the electricity price of your market and the power your purchased.
Traditional hot water heaters can’t keep up with today’s appliances.
Newer solutions on the market, including tankless water heaters, change the way your water is heated.
When you turn on the tap, water flows through the unit and is heated before it reaches the faucet.
There is no storing, no useless heating and definitely no wasted energy on keeping the water at a set temperature even when you don’t use it.
Below are some tips on how to choose the best tankless water heater for your home
If your house is smaller or you don’t regularly use a lot of hot water, buy just one tankless heater for your entire home.
But if you do use a lot of hot water, you can also connect multiple units for whole-house water heating.
Did you know that tankless water heaters are available in both gas and electric?
Make sure to choose the one that is most efficient for your home and your wallet.
Unlike regular water heaters, tankless heaters are sized by the number of gallons of hot water they produce per minute (GPM), not their size.
It is recommended you make a rough list of how much water you use, and whether these usages collide with one another.
For example, you can use the rule-of-thumb sizing to do the estimation on your own.
Here are some rough estimations commonly used:
· 1 bathroom or 1-2 people requires 140,000 BTUs
· 2 bathrooms or 2-3 people requires 190,000 BTUs
· 3 bathrooms or 3-5 people requires 380,000 BTUs
Nevertheless, it is still best that you consult a professional plumber to make sure your tankless water heater is the right size for your home.
Even do-it-yourselfers need to call on a professional sometimes, especially to install a tankless water heater.
This way you are completely confident your system is installed efficiently, effectively and correctly.
Additionally, you can ask for advice on how to suit this system according to your individual requirements.
You can maximize the potential of your heating system by insulating all of your exposed pipes.
This will make your water output produce 2 to 4 degrees warmer when it comes out of your faucet as well as protect your home’s pipes from freezing in the winter.

In this time and age where everything is done instantly, people will not expect to wait several minutes for manually heating the water. So, JNOD instant electric water heaters are a necessity. We walk through 5 reasons on why should choose JNOD instant water heater.
They last longer .
JNOD tankless electric water heaters are built to last longer. Traditional water tanks have a lifespan between 8 to 12 years. However, an instant water heater usually has a warranty of 10 to 15 years and can go on for two decades if maintained properly. When you decide to switch to a tankless water heater, you automatically double the lifespan of your heating system.
Convenient and efficient.
JNOD Instant water heaters have no storage tanks and provide hot water on demand. Also, these water heaters are about 1/5 of the size of traditional water tanks which makes them convenient to fit into smallest of places. Tankless systems are typically mounted on the wall, allowing you to save your home’s floor space. Another advantage is that you can install instant water heaters in more areas of your house and enjoy its benefits.
Saves money and energy.
Although you may have to pay more for a tankless hot water system compared to a traditional water tank, you save a lot by running tankless over a lifetime. First, the tank-free system is designed to last twice as long as a heating system. This makes it a wise financial decision in the first place. Also, you don’t have to pay more for heating water when it is not being used. When you turn the tap on, the water passes through the tankless heater and delivers an ample number of liters per minute to you. Around 30 percent to 50 percent of energy can be saved switching over to an instant water heater.
The water is fresh and clean.
Water from a traditional water tank tends to pick up bits of rust and sediments that build up with the tank. JNOD instant hot water system has no tank and stores no water within which makes the water cleaner and freshen in comparison. Also, instant water heater systems have no bacterial growth issue compared to heaters with a tank.
A Constant Supply of Hot Water.
Traditional water storage tank heaters can heat only a certain number of liters at once. While traditional heaters do keep an ample supply of hot water on hand, it is not a consistent supply. There might be plenty of water available during the day, but as the day passes and more people take a shower, within no time you run into trouble. With JNOD instant electric water heaters, water keeps flowing for as long as you need it. No matter how many family members take a shower, you won’t be running out of water for sure.
When you choose an JNOD instant water heater, you receive a longer lifespan and a reduction in all the disadvantages that come with an outdated heater system.
Is a tankless electric water heater for you?
What is a Tankless Electric Water Heater
Tankless electric water heaters take much less space than storage type as water was heated directly. When you turn on the hot water, cold water travels into the tankless water heater where it is heated by electric heating element. This allows you a constant supply of hot water.
For those large families who using a lot of hot water, install more than 1 heater is common. This will ensure non-stop hot water for showers, laundry and the dishwasher.
Tankless electric water heaters (also called “on demand” units or an instant electric water heater) use 30 to 50% less electricity than tank type, saving about $100 or more per year, depending on water usage.
· Water was heated only when you turn on the faucet.
· The main advantage is that they eliminate the extra cost of keeping big volume of hot water in a storage tank, so you waste less energy.
· Continuously hot water supply, which is ideal for filling a big hot tub.
· Much more compact than a standard water heater and mount on a wall.
Electric vs Gas Tankless Water Heaters
The biggest difference between electric type and gas type is their efficiency. Electric tankless water heaters are typically around 98% or more efficient while gas type is around 80-85% efficient.
Tankless water heaters will free up space that a bulky water heater typically occupies.
The Bottom Line: Pricing and Installation
When you’re pricing a unit, be sure to get an estimate or firm bid on installation costs. This is not a do-it yourself project unless you have pro-level skills. You can contact us (JNOD) for more professional instructions.
