When it comes to instant electric water heater, one of our biggest concerns is the service life of the product, HOW LONG SHOULD YOUR TANKLESS WATER HEATER LAST FOR? Generally speaking, if water quality is good, our heating element can use 8-10 years is no problem. So how do we ensure our product service life?
Firstly, JNOD with special and unique technology in patent heating element, the first cast aluminum heating element technology applied the patent in China. Our patent heating technology--cast aluminum with long lifespan,anti- limescale and high efficiency . We use the patent to make customers to enjoy the best hot water supply.
Second, we have very strict quality control process. We do 100% test for main parts(PCB aging test lasting for 8 hours), we do 100% test for finished product on assembly line and Comprehensive test bench automatic record the testing data.
Third, unlike conventional water heaters, high efficiency models have lower maintenance needs. Advanced technology is used to produce these heaters. Manufacturers adhere to high standards that guarantees efficiency in hot water supply. It also lowers the need for frequent maintenance.
We always put safety and quality at the first position.
Quality is our life.
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:

We will never offer a water heater that is too large or too expensive for your budget. You can trust our experienced team to find the water heater that works for your home or your business at the right price. Contact us today to learn more about our instantaneous electric water heater.
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.
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.
Household Size
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.
Use
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.
Capacity
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.

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?
Example:
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!
