Third, unlike conventional water heaters, high efficiency models have lower maintenance needs. Advanced technology is used to produce these heaters. Manufacturers adhere to high standards that guarantees efficiency in hot water supply. It also lowers the need for frequent maintenance.
We always put safety and quality at the first position.
Quality is our life.
JNOD instant electric water heater is hot water on demand. Hot water has become a necessity today and having access to hot water at one go can be a relief. In this time and age where everything is done instantly, people will not expect to wait several minutes for manually heating the water. So, JNOD instant electric water heaters are a necessity. We walk through 5 reasons on why should choose JNOD instant water heater.
They last longer .
JNOD tankless electric water heaters are built to last longer. Traditional water tanks have a lifespan between 8 to 12 years. However, an instant water heater usually has a warranty of 10 to 15 years and can go on for two decades if maintained properly. When you decide to switch to a tankless water heater, you automatically double the lifespan of your heating system.
Convenient and efficient.
JNOD Instant water heaters have no storage tanks and provide hot water on demand. Also, these water heaters are about 1/5 of the size of traditional water tanks which makes them convenient to fit into smallest of places. Tankless systems are typically mounted on the wall, allowing you to save your home’s floor space. Another advantage is that you can install instant water heaters in more areas of your house and enjoy its benefits.
Saves money and energy.
Although you may have to pay more for a tankless hot water system compared to a traditional water tank, you save a lot by running tankless over a lifetime. First, the tank-free system is designed to last twice as long as a heating system. This makes it a wise financial decision in the first place. Also, you don’t have to pay more for heating water when it is not being used. When you turn the tap on, the water passes through the tankless heater and delivers an ample number of liters per minute to you. Around 30 percent to 50 percent of energy can be saved switching over to an instant water heater.
The water is fresh and clean.
Water from a traditional water tank tends to pick up bits of rust and sediments that build up with the tank. JNOD instant hot water system has no tank and stores no water within which makes the water cleaner and freshen in comparison. Also, instant water heater systems have no bacterial growth issue compared to heaters with a tank.
A Constant Supply of Hot Water.
Traditional water storage tank heaters can heat only a certain number of liters at once. While traditional heaters do keep an ample supply of hot water on hand, it is not a consistent supply. There might be plenty of water available during the day, but as the day passes and more people take a shower, within no time you run into trouble. With JNOD instant electric water heaters, water keeps flowing for as long as you need it. No matter how many family members take a shower, you won’t be running out of water for sure.
When you choose an JNOD instant water heater, you receive a longer lifespan and a reduction in all the disadvantages that come with an outdated heater system.

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.
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.
Figure A: Tankless Water Heater Details
When a hot water tap is opened, the heating elements turn on. Water is heated as it flows through the heating element.
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
