Tankless Water Heaters, are appliances that produce hot water only when called for. Unlike conventional units that keep heated water in a tank that typically holds 40 to 80 gallons, a tankless unit heats water quickly on demand. And consumes less energy because you pay to heat only what you use. Reduced energy consumption means lower utility bills. In addition, a well maintained tankless system can have a life span that’s twice as long as a conventional storage water heater.
Basically, there are two types of tankless units:
Point-of-use water heaters are small enough to fit in tight spaces, typically under the kitchen sink or other areas in the home where hot water is needed. Incorporating several point-of-use units can reduce water heating costs significantly.
Whole house units are capable of simultaneously meeting hot water requirements at several locations, such as your dishwasher and shower.
Sizing is based on the flow rate that’s required and the temperature rise that’s needed. The flow rate is the amount of water that’s needed at any one time, and the temperature rise is the difference between the temperature of the water coming into the home and the temperature of the water flowing from the faucet. If the temperature of water coming into your home is 20 degrees, and you want water that’s 60 degrees at the faucet, the rise would be 40 degrees.

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.
Now a day, tankless electric water heaters are getting better and better, it is a very wise choice for people saving energy bills, approve their financial status. Especially those using JNOD patent cast aluminum heating element, up to 97% heating efficiency will better save much more money than others.
Not decide yet? Then, take a look to below pros of tankless electric water heaters, it will help on the decision making.
Pro #1: Instant Endless Hot Water
Tankless water heaters can provide unending stream of hot water almost instantly. It supplies hot water within 3 seconds without the inconvenience of bulky storage tanks.
Pro #2: Longer Lifespan
For using our patent heating element, structure itself could anti-limescale, the element will not have limescale inside, even in very hard water area, it could still work at least 5-8 years, some even could last longer, like 10 years!
Pro #3: Cut Off “Standby Loss”
Unlike the storage heater, tankless type will only consume electricity when user open the valve, and heating efficiency of our heating is 97%, minimized energy loss, saving energy paid every day.
Pro #4: Space Savings
Tankless electric water heaters are much smaller than bulky storage models, even smaller than gas water heater. Installers usually mount them on a wall in an inconspicuous place in the basement. In smaller homes, the space savings is a welcome benefit.
Yes, but a tankless water heater does more than save you money.
Savings: Space
Since tankless water heaters do not have tanks, they take up less space. You don’t need to have a utility room or area in the garage for your water heater. Your tankless water heater can be stored in a closet or under the sink. Extra space is valuable these days, especially if you’re living in a smaller home or condo.
Savings: Energy
Traditional water heaters hold around 30-50 gallons of water and keep it heated until you’re ready to use it. Depending on the size of your family and the amount of water your family uses, this could be costly. (Did you know that water heater energy usage is the second-highest source of energy use in the average home?) Tankless water heaters don’t hold water, so they heat the water as it comes in—no constant energy to keep 15 milk jugs’ worth of water hot.
Savings: Time
Tankless water heaters save you time in the morning because the water is heated as it comes through until you are finished. While a traditional tank does have hot water on demand, that’s only until the tank runs out. Then you have to wait for the tank to refill and warm up the water. Tankless heaters don’t have that lag time because there’s unending water flow from the tank to the tap.
Savings: Money
Most new homes have a traditional water heater already installed when you move in. If you’re looking to replace the traditional tank, however, there is some work required. While installing a tankless heater might present a higher price tag than expected, the overall financial gains will overcome that deficit. It will raise the initial investment, but it’s an investment worth looking into for your home and your family. When comparing the overall savings of space, energy, time, and money – the savings really can add up.

The operation of an electric water heater is essentially the similar as that of a gas heater. It heats the cold water inside the pipe using the electric heating elements after bringing it in through the dip tube. Through the heat-out pipe, hot water rises in the tank and is transported throughout the house or shower .
It with two pipes— one for cold water inlet and the other for hot water outlet— makes up the geyser. It is equipped with thermostat-controlled heating components. Water is not heated above a predetermined temperature value by the thermostats. Typically, a metal casing is used to enclose the tank, which is then covered with an insulating material.
Jnod electric geyser is the tankless ,which is no need to pre-heat the water. The hot water can be come out instantly. It has temperature constant function,the temperature difference is only ±1 degree Celsius. Very comfortable and convenient .
What's the best moment of the day? The answer is to take a bath. You can wash away the tiredness and feel clean and comfortable.
You probably do not give your water heater much thought most of the time . After all, if a home appliance is performing its intended function, it will eventually become invisible.
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.
JNOD tankless electric water heater with up to 97% high efficiency,no need to preheating and can save water perfectly . You don't need to worry about wasting water when you take a bath . Perfect bathing experience.
