Water heaters can be a costly investment for home owners that you’ll be living with for over a decade. That’s why it’s important to consider cost, efficiency, and longevity of your new water heater. We’ve put together this comparison of Instant Electric Water Heater Against Storage Electric Water Heater to help homeowners and contractors decide on the type of water heater that’s best for you.
Instant electric water heater, also known as on-demand electric water heater or tankless electric water heater, use high efficiency heating element to heat water as it runs through inside the element and deliver it directly to faucets or shower without a huge water tank. Instant electric water heater is found that usually have 30% more efficiency than storage type.
Advantages
instant 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.
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 uses, we will help to fulfill your different hot water requirements !

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.
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.
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.
Recognize Any Of These Signs? Invest In A Tankless System Today!
If you decide a tankless water heater is the way to go, the size of your home will help determine the size of the heater you need, whether you need more than one, and where the heater(s) should be located.
