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.
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.
Electric Tankless Water Heater Price:
JNOD instant electric water heaters are applied for both kitchen sink and shower, and we will always give you exactly what you need. We will never offer a water heater that is too large or too expensive for your budget. You can trust our experienced team to find the water heater that works for your home or your business at the right price. Contact us today to learn more about our instantaneous electric water heater.
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.
