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!
One of the worst starts to your day is trying to get ready for work and getting a cold shower because someone else used all the hot water. That’s not a good experience.
Additionally, the water cools and is re-heated in the tank several times each day while no one is home. This is just wasting energy and running up your utility bills. Some of these issues can be addressed by installing a tankless water heater. Endless hot water and lower energy bills are two reasons homeowners are switching to tankless water heaters.
Tankless water heaters save money in the long run . Endless hot water, additional storage space and lower energy bills are just a few reasons homeowners are switching to tankless water heaters.
The U.S. Department of Energy estimates gas-fired tankless heaters save an average of $108 in energy costs per year over their traditional tank counterparts, while electric tankless heaters save $44 per year.Many homeowners, however, see benefits of a tankless water heater beyond energy savings.
These heaters also save space with a compact design, last longer and are better for the environment because a rusty tank doesn’t end up in the landfill.
Tankless water heaters also typically have a longer warranty.

Endless hot water endless technology. JNOD‘s tankless waters are worth the Investmenet .
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 .

Electric or gas? Which is better? In reality, there is no single answer to this question. The following factors all play a role in choosing what type of tankless water heater is best for your needs:
1.Efficiency / Operating Cost: While gas tankless water heaters are certainly more efficient than their tank cousins, their efficiency usually peaks at 80-85%. Conversely, most electric tankless water heaters are 98+% efficient. electricity costs are more stable and projected to rise much slower than gas rates in future.
2.Installation: Gas tankless water heaters have complex venting and combustion air supply requirements, especially when installed in a confined space, is that these requirements can make installation very expensive. Electric tankless water heaters are very small, and they can be installed in a closet, under a sink, in a crawl space, or a wide range of other areas where a traditional tank or gas tankless cannot. the installation of an electric tankless water heater is generally much cheaper than the installation of a gas tankless water heater.
3.Maintenance, Service Life and Warranty: Electric tankless water heaters require very little maintenance. In fact, other than cleaning the inlet screen filter occasionally. On the other hand, gas tankless heaters should be inspected annually by a trained technician to ensure safe fuel combustion and performance.
4.Environmental Impact: Electric water heater is no greenhouse gas emissions, small size reduces environmental footprint in manufacturing and ultimate disposal - future electricity generation to come from green sources such as solar, wind, and wave energy, gas water heater produces greenhouse gases and increases reliance on fossil fuels
In JNOD, we have a professional team to help you choose models with a most suitable electric water heater and we will help to fulfill various demands for hot water requirements!
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.

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.
