As automation or immediacy is becoming more and more popular in the world, it comes as no surprise there are instant hot water systems. Also referred to as tankless hot water system, these systems give you virtually endless hot water, and you only pay for the water you use. Additionally, there's no need for those ugly, bulky storage tanks!
These all sound too good to be true. You have probably even thinking that there is a catch somewhere. JNOD has over 13 years of experience in hot water, and we are here to let you know why to install an instantaneous electric water heater (Tankless electric water heater).
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.
Electric Tankless Water Heater Cost:
When installed appropriately, an instantaneous electric hot water system will save you money in the long term. While they are more costly upfront, you will save money by only paying for the hot water you use.
On average, we have found that electric tankless water heaters have longer than storage tanks as well. They do not need to be replaced the absence of sacrificial anodes every so often as is the case with storage tanks. JNOD tankless water heaters electric are used with the cast aluminum heating element. Electricity and water separate to work, which is a great help to have a longer life span and avoid the water scale.
So electric tankless hot water system will be sure to make your wallet happy.

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.

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.
JNOD tankless water heater with compact size and patent heating technolody . Compared with the storage water heater and gas water heater, the higher heating efficiency (up to 97%). In the current energy shortage situation, it is more environmentally friendly and more economical. Easy to install, eliminating huge installation costs caused by complex installations. Worth the investment.
Endless hot water endless technology. JNOD‘s tankless waters are worth the Investmenet .
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.

One of our professional, JNOD will assess your unique needs, and recommend the type of water heater that would best meet your expectations and budget. Be sure to ask about special promotions!
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.

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 !
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!
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.
