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.
When it comes to tankless electric water heater, one of the biggest mistakes is buying a unit that is too weak to satisfy whole house hot water needs.
You don’t want one that is too small to supply whole house hot water needs, nor too big that power cord could not support the amperage when the instant electric water heater works.
The power of tankless water heater should be as appropriate to your household hot water needs as possible.
How many kW for JNOD tankless electric water heater?
To properly answer which power do you need, you have to figure out below points beforehand:
1. How’s the temperature of inlet water at coldest time?
2. How many degrees could the certain heater heat up at how much water per minute?
If inlet water flow has 2L/min, max temperature rise of a 5kW model could be up to max. 35℃, But in the relatively cold area, winter time the coldest water temperature is 0℃, plus 35℃, it could only reach 35℃, even it works with full power, there still not hot enough for shower use.
But for the warmer area, in winter, inlet water still have 12℃, then total it could heat up to 47℃, it was quite good enough for your shower use.
In JNOD, we have a professional team to help you choose models with a most suitable power, no matter for single shower use or multiple points use, we will help to fulfill your different hot water requirement!
As automation or immediacy is becoming more and more popular in the world, it comes as no surprise there are instant hot water systems. Also referred to as tankless hot water system, these systems give you virtually endless hot water, and you only pay for the water you use. Additionally, there's no need for those ugly, bulky storage tanks!
These all sound too good to be true. You have probably even thinking that there is a catch somewhere. JNOD has over 13 years of experience in hot water, and we are here to let you know why to install an instantaneous electric water heater (Tankless electric water heater).
Energy Efficiency Explained:
Standard water heaters have an energy factor of approximately 0.60. Meaning that approximately 60% of the energy generated is used to heat the water, and 40% of that heat is lost in this process. That heat goes out the vent. Instantaneous electric water heater have a 0.80-0.99 energy factor. JNOD electric tankless water heaters are 98% thermal energy efficient. You will greatly reduce your heat loss when you convert to tankless, and use less fuel to heat the same volume of water.
Electric Tankless Water Heater Cost:
When installed appropriately, an instantaneous electric hot water system will save you money in the long term. While they are more costly upfront, you will save money by only paying for the hot water you use.
On average, we have found that electric tankless water heaters have longer than storage tanks as well. They do not need to be replaced the absence of sacrificial anodes every so often as is the case with storage tanks. JNOD tankless water heaters electric are used with the cast aluminum heating element. Electricity and water separate to work, which is a great help to have a longer life span and avoid the water scale.
So electric tankless hot water system will be sure to make your wallet happy.
Electric Tankless Water Heater Price:

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.
JNOD instant electric water heater is hot water on demand. Hot water has become a necessity today and having access to hot water at one go can be a relief. 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.
