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.
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!
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.

Is a tankless electric water heater for you?
What is a Tankless Electric Water Heater
Tankless electric water heaters take much less space than storage type as water was heated directly. When you turn on the hot water, cold water travels into the tankless water heater where it is heated by electric heating element. This allows you a constant supply of hot water.
For those large families who using a lot of hot water, install more than 1 heater is common. This will ensure non-stop hot water for showers, laundry and the dishwasher.
Advantages
Tankless 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.
Electric vs Gas Tankless Water Heaters
The biggest difference between electric type and gas type is their efficiency. Electric tankless water heaters are typically around 98% or more efficient while gas type is around 80-85% efficient.
Tankless water heaters will free up space that a bulky water heater typically occupies.
The Bottom Line: Pricing and Installation
When you’re pricing a unit, be sure to get an estimate or firm bid on installation costs. This is not a do-it yourself project unless you have pro-level skills. You can contact us (JNOD) for more professional instructions.

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.

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.
Temperature Rise
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.
