Water heating techniques have evolved over the years as companies come with more innovative, cost-effective and efficient water heating techniques. One of the latest developments is the electric tankless water heater.
Unlike traditional water heaters, electric tankless water heaters provide continuous hot water by heating the water instantaneously as it runs through the unit.
Although these units have been used for decades, their popularity is gaining momentum in the United States and other parts of the world as people appreciate their benefits over traditional water heating methods.
We have compiled a list of some of the best 6 electric tankless water heaters that offer excellent flow rates, energy efficiency, and durability as follows;
This Ecosmart electric tankless water heater will provide a continuous and endless supply of hot water. It is easy to use with digital temperature control that gives you the latitude to control the water temperature at 1-degree increments.
The compact size and design of this water heater are among its best features as you can install it anywhere to enjoy hot water whenever you need it.

Moreover, its advanced flow control features make it consistent and reliable in delivering continuous hot water whenever you need it.
With two heating chambers, this unit is well equipped to handle all the hot water requirements for residential use. It has a self-modulating feature that marches heating power to water demand which makes it highly efficient in terms of energy usage and delivering hot water whenever needed.
Its temperature control, easy installation and high quality and easily replaceable components make this unit a recommendable choice.
This unit comes with some cool features that will let you enjoy hot water instantaneously and with high energy efficiency.
Among the top features is the self-modulating technology and advanced flow control that ensures continuous supply of hot water regardless of the demand. Moreover, this unit is easy to install and comes in a sleek design that can fit in any room, RV, boat etc.
Although this unit is gas powered and will require venting when being installed, it is an ideal choice when you are looking at huge hot water demand in the household.
It is very efficient cost-effective and provides reliable and consistent hot water at all times. Moreover, this unit is constructed with stainless steel which does not easily corrode and therefore guarantees years of leak-free use.
What is most attractive about this model is the unlimited choices of places you can choose to install it.
Be it under a sink, on top of shelves, RVs and boats; this unit will just fit right in. Its 2.5 gallons/min flow rate although not high enough to cater for huge hot water demands is sufficient to deliver hot water for everyday use around the kitchen or shower.
The choice of the best electric tankless water heater will depend on your individual needs and circumstances.
When you are in the market for a tankless water heater, you should reconcile your hot water needs with the flow capacity of the unit you intend to buy.
This is because although all tankless water heaters supply endless hot water, the hot water isn’t stored anywhere but is heated directly as it runs through the unit.
As such, if you intend to use your tankless water heater to supply hot water to more than two points that are being used simultaneously, then you will need to look for a unit with powerful heating elements otherwise you may end up with lukewarm water if you go for a smaller unit.
Furthermore, you may need to stagger usage of the hot water if your needs require a lot of hot water. This is especially so if your faucet at the point of use has a heavy flow or you are using more than one point at a time.
This will help avoid the issue of getting lukewarm water when you need hot water. The issue of choosing the right size of unit for your hot water needs is a big factor here when you need a reliable and consistent supply of hot water.
Basically, there are two types of tankless water heaters; electric and gas powered units.
The gas-powered models are much faster and more efficient in heating and providing a continuous supply of hot water. This makes them ideal for whole-house hot water use because of the heat output and faster response time required.
However, these units will require venting and are generally larger and costly than the electric models.
Electric models, on the other hand, are much smaller and with varied designs and construction. They do not require any venting and are much simpler to install and use. Some models will feature a plug-in design while others have to be hardwired; especially the larger electric models.
They are quite efficient and faster although they cannot match the gas models when large quantities of hot water are needed at ago.
Because tankless water heaters do not store hot water, their rated flow rate determines the capacity of hot water they can provide at a time.
Bigger flow rates usually mean they can provide more hot water and can be used for multiple points of use while smaller models with small flow rates are ideal for installation as point-of-use units.
The point of installation for this unit determines the type of unit you choose. There are tall units that are ideal for installation anywhere where space is not a limiting factor while the smaller short units can be installed in constrained spaces and still provide the same effective service.
Dry fire protection
This feature helps prevent the upper element of the unit from burning out when the unit detects no water around it.
As with any other electric appliance, high energy efficient tankless water heaters are not only good for the environment but will also save you money as the operating costs for highly energy efficient models are considerably low.
This includes features such as Wi-Fi capability and features that allow other operating features such as temperature to adjust accordingly depending on your needs and use patterns.
These features offer better energy efficiency, improved performance and better durability for these units.
