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.

Tankless heaters come in all different sizes. There are small water heater units, designed for point-of-use that only draw 110-120 volts.
The first step in determining which size water heater is right for you is to understand what you'll be requiring from the tankless. If you're looking for a larger unit, you should check out our tankless buyer's guide. But if a 110-120volt water heater meets your needs, then read on . . . this article was written for you.
110-120Volt Tankless Water Heater for Showers
Look, we're not going to lie, if you're not in the tropic and shopping for a 110-120volt tankless water heater for your home shower you'll most likely be disappointed with the results. 110-120volt's just isn't a lot of power to deliver a hot shower beside tropic area.
It can, however, get things going until your main water heater can take over, but most of the point-of-use heaters of this size are designed to be used for a single sink. In most situations, that means hand washing.
Although, there are exceptions. If you live in an area where the incoming water temperature is high, a 110-120V tankless such as JNOD XFJ135KH may be able to take a long shower. But if you live in Alaska, or most anywhere else, these units just won't be able to get the job done.
Best 110-120 Volt Tankless Electric Water Heater
The best 110 Volt tankless we've been able to find is the XFJ135KH by JNOD. Although the sales material lists this unit as a 120v tankless, JNOD has tested it to operate at 110v (more on this below).
The XFJ135KH is hydraulically controlled, making it incredibly quiet. It has a stainless-steel cup with copper heating element and with plenty of built-in safety features, and the superior design and workmanship means this unit is suitable for residential or commercial use.
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 .
Warm congratulations to JNOD for being recognized by the National Laboratory, becoming one of the first enterprises with national accreditation laboratory qualifications in the electric water heater industry.

When buying a tankless water heater, most people don’t know what size tankless water heater they need.
If you are looking to install tankless electric water heater and you’re unsure of which size you should buy, here are some factors you should take into account:
- The size of your house
- Flow Rate (GPM): How much hot water you will need at any given time
- Temperature Rise (ΔT): The difference between the incoming cold water temperature and the desired temperature
Your Household Size
If water heater is too small, it will result in it not being able to produce enough hot water for your household demand. For example, you might not be able to run more than one shower at a time, especially in the freezing winter.
On the other hand, water heater is too large, it will end up being more costly than necessary, since you will be paying more upfront for the larger size (although it could be useful if you plan to upsize your home later).
Hence, to work properly, a tankless water heater needs to be just the right size to meet your home's hot water demand.
Rate of Water Flow
Tankless water heaters are often referred to as demand water heaters. On-demand refers to having continuous hot water output for as long as the hot water tap is open. However, having multiple hot water taps open together will reduce the hot water output. Having too many hot water taps open at once will produce lukewarm water if the tankless water heater’s output capacity is exceeded.
To help you estimate the flow rates of most of your faucets, we shared some typical flow rates below. The actual flow rates may be different for your house and different appliances.
After you have calculated the flow rate of every faucet in your house, you must now determine how much heat your heater needs to generate to give you the required heat in your water outlets. We’ll take into consideration the temperature of the water that flows into your home and the temperature of the water that you want to flow out of your tap to determine the required temperature rise.
You might still have some questions relating to the size of instant electric water heater you need, please let us know in the comments below.
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.
Yes, but a tankless water heater does more than save you money.
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.
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.
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.
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.
