Electric Tankless Water Heater – What is it? 

To better understand what an electric tankless water heater is, it is helpful if you first understand what a with-tank water heater is. A water heater with a tank stores water in the tank and heats it. It also stores the heated water in the tank for you to use later on. So you can basically switch on the button to heat water and then use that hot water whenever you want.

A water heater with a tank usually takes around 30-50 minutes to heat the water. The amount of time it takes to heat the water depends on the capacity of the tank. A heater with a tank capacity of 30 liters takes approximately 30-40 minutes to heat water. And the heater with a higher capacity takes more time.

Electric tankless water heaters, on the other hand, do not have a tank at all. Instead, they have a heating element that instantly heats the water. So, with a tankless water heater, all you need to do is switch on the geyser button and the hot water tap, and within just one 1-5 seconds, you will have a continuous supply of hot water.

In a with-tank water heater, you get a limited quantity of hot water at a time. And in a tankless water heater, you get unlimited hot water. Tankless water heaters use 30 to 50 percent less energy than with-tank water heaters because you do not need to keep the geyser on for a long time.

Electric tankless water heaters are, without a doubt, more energy and cost-efficient than traditional water heaters. Even though tankless water heaters are more expensive than traditional ones, they save more money in the long run.

Buying Guide for Electric Tankless Water Heaters

If you did not like the tankless water heaters we have recommended above, you could keep searching for the right one for you with the help of this guide. So without any further delay, read on to know more about electric tankless water heaters.

Things to Consider When Buying an Electric Tankless Water Heater

There are a few important things you need to consider while buying an electric tankless water heater. To make the right choice, you need to understand the hot water needs of your household. If you want to make the right choice, don’t go for the cheapest or the most expensive electric tankless water heater.

Just because it is cheap or expensive won’t determine if that particular water heater would be good for you. You need to consider if you live alone or with a large family. And besides the hot water demand of your household, there are a few more things you need to consider while buying an electric tankless water heater. Let’s explore these important considerations in detail.

Ease of Installation 

The first and one of the most important things to consider while buying an electric tankless water heater is the ease of installation. Electric tankless water heaters are overall easy to install. However, some household electrical systems are not compatible with these types of heaters.

No doubt that tankless heaters are much more inexpensive than gas water heaters. However, since some household electrical systems may not be compatible with tankless heaters, you might need to change the whole electrical system. This will cost you a few extra hundred dollars. So make sure that electric tankless water heaters are compatible with your home and are easy to install.

Does the design matter?

Electric tankless water heaters have a rather simple design. They may not look fancy or even too appealing. However, the ease and efficiency with which they provide hot water is definitely enough to over-look the simple design aspect. They are also much easier to troubleshoot than gas water heaters.

In fact, they are so easy to troubleshoot that you could repair, diagnose, and troubleshoot the machine on your own. This means that electric tankless heaters have a longer life than gas water heaters. Electric tankless water heaters are also really small in size. As you may have seen in our recommendations, they are also available in mini models that fit easily fit anywhere. They are about the third the size of gas heaters.

Costs and Efficiency 

Another important thing to consider while buying an electric tankless water heater is its efficiency and costs. Tankless heaters are extremely energy efficient and use over 98 percent of the electricity they receive to heat the water. This means that no electricity is lost or wasted, saving you lots of electricity and energy costs in the long run.

Water flow 

Consider the water flow of the electric tankless water heater before you buy it. You have heaters that have less water flow, which is suitable for smaller families. These water heaters are known as single-use water heaters. If you have a large family, you will need the whole-house heaters that provide 3-9 gallons of water per minute to your entire house.

Safety features 

Electric water heaters are really convenient devices. However, they also come with risks. So, choose a water heater that comes with safety features to protect you and your family. When buying a tankless water heater, look for self-protection features like temperature lock, freeze protection, self-modulating technology, and much more.

Warranty 

Always go for a heater that comes with a long warranty period. An electric tankless water heater is not something you change every few years. Once you buy it, you use it for at least 20 years. So, to save up on maintenance and repair charges, look for a heater that comes with a long warranty period.

Important Features of an Electric Tankless Water Heater: Tankless Water Heater Requirements

Now that you know the important things you need to consider while buying an electric tankless water heater let’s explore further. In this section, we will explore the important features of a high-quality tankless water heater.

One of the most important features of a quality heater is that it can be installed anywhere. Heaters that come with flexible installation spots can be installed anywhere as long as there is a plug nearby to put them in.

Another important feature is the time it takes to get hot water. Some tankless heaters give you instant hot water, while others take a minute or 50 seconds to heat up and get the hot water flowing. Electric water heaters consume more energy to heat the water and are also more expensive than gas water heaters.

An amazing feature of tankless systems is that you get on-demand and on the spot hot water. You can have hot water and use it for anything you want every time you open the water faucet. Electric tankless water heaters also have maximum energy efficiency. They use almost 98 – 99 percent of the energy they receive on heating up the water without wasting any energy at all.

Another important feature of a quality electric tankless water heater is that it provides protection from diseases. Stagnant water is more susceptible to the build-up of bacteria in it. But since the water is constantly flowing in electric tankless water heaters, there is no scope for the build-up of harmful bacteria. This keeps you safe and healthy and free from bacteria and virus invasion.
