Choosing a new water heater is important. Water heaters consume a lot of household energy. The right water heater can make a big impact on energy efficiency in your home. When deciding which of the different types of hot water heaters will work best for your home, there are many things to consider.
Household Size
Tankless electric water heaters are also called instantaneous or on-demand water heaters. Rather than use a storage tank, the water circulates through a heating element that heats the water as needed. Tankless water heaters are rated by the gallons per minute they provide, and the average life span is 20 to 25 years.
Use
How you plan on using a water heater determines how much hot water it needs to supply, as well as whether you need a single unit, individual units at several points in the house or a combination of solutions.
Capacity
In a tankless water heater electric, the capacity is measured by flow rate, calculated in gallons per minute. Getting the correct size of tankless heater requires figuring out how much hot water you may need at any given time, coming up with a flow rate number and then matching that figure to the measure on a given system.
Tankless water heater tips to consider
- Overheat protection: Keeps the water from overheating in the system by cutting off the power supply once the set temperature is reached.
- Digital display: Makes it easier to monitor the temperature and make precise adjustments.
- Automatic constant temperature: A stable water temperature is a great help to protect your skin, and also get the better experience for using hot water.
- Leakage protection: Provide an important safeguard for your family life.

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.
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.
You might still have some questions relating to the size of instant electric water heater you need, please let us know in the comments below.
Tankless Water Heaters, are appliances that produce hot water only when called for. Unlike conventional units that keep heated water in a tank that typically holds 40 to 80 gallons, a tankless unit heats water quickly on demand. And consumes less energy because you pay to heat only what you use. Reduced energy consumption means lower utility bills. In addition, a well maintained tankless system can have a life span that’s twice as long as a conventional storage water heater.
Basically, there are two types of tankless units:
Point-of-use water heaters are small enough to fit in tight spaces, typically under the kitchen sink or other areas in the home where hot water is needed. Incorporating several point-of-use units can reduce water heating costs significantly.
Whole house units are capable of simultaneously meeting hot water requirements at several locations, such as your dishwasher and shower.
Sizing is based on the flow rate that’s required and the temperature rise that’s needed. The flow rate is the amount of water that’s needed at any one time, and the temperature rise is the difference between the temperature of the water coming into the home and the temperature of the water flowing from the faucet. If the temperature of water coming into your home is 20 degrees, and you want water that’s 60 degrees at the faucet, the rise would be 40 degrees.
