A hot shower or bath is one of life’s little but most precious pleasures. And so, if you’re building a tiny house, you need a reliable water heater. But how to choose the best water heater for your tiny bathroom?

We’ve compiled a list of the best tiny house tankless electric water heaters from JNOD product catalogue today, according to user reviews, personal experiences, and top selling units.

1. Wide Applicability FE-T Model

FE-T 240V Instant Electric Water Heater is the perfect no-nonsense water heater for tiny house homeowners just looking for that simple, affordable solution. Several powers to your choices: 3.5/4.5/5.5/7/9/11/13.5kW, so you can find one to works for your home.

With an installation time of just one hour and a maximum flow of 7L/min, FE-T is also quite smart to adjust and operate with its touch key or WIFI function.

2. Super MINI KF Model

At just 2.9kg and tucked into such a compact frame, KF Electric Tankless Water Heater can be installed almost anywhere you might want, which is perfect for the size limitations of tiny homes. The small size also means that installation is simple and straightforward, so anyone who can read the instructions can safely install this in their home in no time at all. No need to call in a professional to install to help you heat water.

KF tankless hot water heater is often described as the best tankless water heater for tiny homes. Its compact shape means you can easily install it near its point of use, and in just 15 seconds you can enjoy hot water flowing. But the powers to select are 3.5/5.5/7kW, So it is also ideal for sinks and low-flow showers.

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.

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.

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

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:

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

1. Consider the size of 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.

2. Gas or Electric?

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.

3. Finding the properly sized tankless water heater for your home.

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.

4. Call a professional plumbing company.

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.

5. Easily maximize your water heater’s efficiency.

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.

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.
