You will also want to know what features deserve your attention, so we also have here the most important factors that you must consider when looking for the best.

Outstanding Features to Look for in Electric Tankless Water Heaters

In this section, we are going to discuss in detail what factors you should be looking for when choosing an electric tankless water heater. No two units are alike, which is why taking these factors into consideration will allow you to narrow down your choices. With so many brands to choose from, you might get yourself lost on promises that may or may not come through.

Here are some of the things you should watch out for to make sure that you are only getting the best electric tankless water heater there is.

On-demand Heating Capabilities

A lot of electric tankless water heaters promise that they will be able to deliver an instant and continuous flow of hot water. Unfortunately, not all of them do. It can be very annoying and frustrating when you cannot have hot water especially when you need it. Also, it totally goes against the reason why you got yourself a water heater in the first place.

An important feature that you should look out for in a water heater is the thermos optical sensors. Quality models have built-in thermos optical sensors that deliver hot water any time you want it. These sensors also prevent temperature spikes either at the nozzle or at the faucet, which also ensures safety for you and your family.

When choosing a tankless water heater, you might want to check if the model has the capability to heat water as it passes through the unit. This will be beneficial for you, especially if you do not want the inconvenience of storing hot water just like in tank type water heaters.

There are also models that offer infrared heating, a process of combining carbon coating heating element technology with quartz tubes to generate hot water. In addition, it does not directly come in contact with metal. This technology allows faster water heating, which ultimately saves you time and money in terms of energy consumption.

Energy and Space Saving Capabilities

Heating of water only accounts for at least 18% of your electric bill, according to Energy Saver. With this, we would recommend that you select the most trusted brands that will be able to provide you instant and a continuous flow of hot water through the thermos optical sensors’ built-in technology.

Another outstanding feature that you need to watch out for is the self-modulating technology, which can be found on some of the models presented in the review below. If you are not yet familiar with it, this technology prevents unnecessary use of energy. Efficient water heaters only use the amount of energy required, which can really help you in terms of your energy bills.

When choosing a water heater, you must also take into consideration the energy consumption. You might want to select one that you only need to turn on when you need hot water. If you have this type of water heater in your home, you will be able to cut down on water heater expenses by up to 50%. This will allow you to save even more money in the long-run.

As we all know, traditional water heaters take up a lot of space. However, with electric tankless water heaters, you no longer should worry about that, as you only need to mount it. You can install the unit right under the shower head, thus, freeing up more floor space that you can also use for storage.

Price and Long-term Cost

These might be two of the most important factors why people are now choosing electric tankless water heaters over gas-operated water heaters. While it goes into comparison with other types of water heaters, it also is vital when choosing an electric tankless water heater.

As we all know, the price of the unit alone is one of the defining factors whether you should buy it or not. Price evaluation is useful especially if you are just starting to look for an electric tankless water heater. If you are on a tight budget, you must review all the features of the water heater first to determine if the price is worth it.

Electric tankless water heaters do not come cheap. However, they pay you back for its energy saving capabilities, which makes consumption even more economical. They are very efficient to use, as they can reduce standby heat loss. It is also considered a great investment because it can last up to 20 years with proper maintenance. In a way, it will pay for itself by giving you a long-lasting service.

When choosing an electric tankless water heater, you must ensure that you are buying an energy efficient unit. This type of water heater generally has a longer lifespan than most water heaters out there. If you buy a cheap one, you will only be getting poor performance, as well as a unit that will surely not last long enough.

There is nothing more frustrating than not getting your new electric tankless water heater installed properly, either by you or a professional. Electric water heaters are relatively a lot easier to install than most gas-powered water heaters and it should not be a problem for your or a professional to install one in your home. The reason is that with electric tankless water heaters, you would not need to worry about combustion air supply or venting, unlike with gas-powered water heaters.

When choosing an electric tankless water heater, you should take into consideration the unit’s installation. While this is something performed by professionals, you must also be able to comprehend the manual with ease. Seeking professional help is advised, as you might void the warranty built into the price of the unit, if ever you damage the unit during installation. To add, water heater manufacturers have a way of telling if the damage was caused by an authorized or an unauthorized person.

Another thing to consider when choosing an electric tankless water heater is the maintenance of the unit. We all know that a well-maintained unit will deliver an outstanding performance for a long period. In most cases, all you have to do is to clean the water inlet. It also does not require an annual inspection of the unit, unlike in gas-powered water heaters.

While some require cleanup every few months, some also offer zero maintenance models. Having to properly maintain a water heater can be a tedious task, which is why you might want to consider choosing a model that requires only minimal maintenance. This will save you a lot of time and effort.

To address this issue, you add the number of gallons per minute of hot water being used at the same time. With this, you will be able to determine which of the models is the right one for your home. When choosing a water heater, you also have to check if the unit will provide you unlimited hot water even if it is being used by two people at the same time. We all know how frustrating it can be if the water heater suddenly runs out of water, right?

Protection Against Disease

Tank type water heaters store water all day and night, which makes water to become stagnant if left for a long period.
