What is a Hybrid Water Heater?

Given how new these units are to the market, we wouldn’t be surprised if you haven’t heard of them before. For all those not familiar with these units, they are the newest generation of water heaters which are a combination of conventional and electric water heaters.

Over the past few years, these heaters have infiltrated the market and become one of the most common types of water heater that users have invested in. They allow the heating process to switch between conventional and electric automatically and come with either a tank or tankless system that makes it a true hybrid.

How Does a Hybrid Water Heater Work?

The working of a hybrid water heater is not too complex to understand. What these units basically do is pull heat from a number of sources, instead of creating the heat itself, which can take a longer time. How is that done? Well, here’s an example for better understanding.

Given it's summer season and the hybrid heater's functioning, what the unit will do is use the heat from the surrounding air and therefore, utilize the minimum amount of electricity to create heat. Such a process will not only be considerably faster but also helps save electricity.

How to Choose a Hybrid Water Heater

As mentioned earlier, hybrid water heaters are not extremely complex units. But that doesn’t mean you could pick just any unit and it would work well. Picking the right hybrid heater takes keen consideration of certain important aspects. Here are a few factors that need to be kept in mind while choosing a hybrid heater for yourself.


The size of the tank is one of the most important aspects to consider. While considering the size, you are actually looking at two things. The first is the size of the unit as a whole, while the other is the tank that it comes with it.

The size of the unit is important since it determines if it would be able to fit into the area determined for the heater, while the capacity of the tank dictates how much hot water the unit is capable of storing.

EcoSmart ECO 11


When we speak of the tank, we’re not talking about its capacity since that has already been discussed before. What is also important is the material used for the tank. The ideal tank comes with a glass lining to ensure better durability and avoids any build-up on the inside, keeping your water clean.


The display of the hybrid water heater may not be a deciding factor for which unit you invest in, but it definitely has a huge role in your satisfaction with the given unit. If presented with the choice, it is always advisable to pick a unit that comes with a simple, straightforward design so you face less problems in the future.

Why it Stands Out to Us

The comparatively low price of this unit was a great plus point for us too, but what really stood out to us was the availability of the product in two variables on the basis of point of use. Such a choice can allow users to pick a unit that is more ideal for their specific use.

According to all those users, this product, too, displayed the perfection of design and flawless functioning they have observed in every other product by Rheem and highly recommend it to others.

Why it Stands Out to Us

Of all the features this electric water heater has in store for us, what really makes it stand out from the rest is its 50-gallon tank. Most water heaters that come with a tank are not big enough to store a sufficient amount of hot water, but with this unit, you will never have that issue, thanks to its sufficiently-sized tank.

Who Will Use This Most

Rheem products are designed to provide users with a number of features and conveniences. This unit serves to be the ideal one for all  users looking to invest in a hybrid water heater that is not only electric but also features a large tank for better use.

Investing in this Rinnai unit has been the best decision the users have made, according to their own reviews. They have found it not only satisfying in terms of functionality, but also highly impressive given all the extra features it provides, compared to other basic units.

Why it Stands Out to Us

What we love about this unit is its WiFi capability. Almost every item we use in the present day is WiFi-enabled, so why not your water heater, too? It provides enhanced functioning and truly makes it the ideal hybrid water heater for the present generation.

Who Will Use This Most

The greatest limitation of a water heater with a tank system is the limited amount of heated water storage. If you were to use an amount greater than the capacity of your tank, you’d have to either wait longer in-between or simply make do with cold water. But with a tankless unit, you no longer have that issue. So if you, too, are looking for a tankless water heater to invest in, then it’s this one you should consider.

Bottom Line

If you are tired of the limited amount of water your heater tank stores, and are no longer willing to wait until it gets around to heating more water for your use, then ditch your old heater and invest in this unit right here. Not only does it guarantee a stream of continuous hot water, but also great energy savings.

What Recent Buyers Report

Users that have invested in this unit have claimed to benefit from it greatly. They claim that it not only provides them with the best of hybrid water heating technology but also allows great savings too, in terms of space, as well as money. To sum up, it is all they could ask for.

Why it Stands Out to Us

The one feature this unit offers that we think makes it worthy of being on this list is the number of choices it provides its users with. Users can not only choose between a natural gas and low propane based system, but also choose between a lower and higher BTU rating, and spend money on what they really need.

Who Will Use This Most

While an electric water heater may be quick and efficient with its functioning, the quality of performance provided by a natural gas water heater is simply unmatched.

Users that have recently bought this unit for themselves have been very satisfied with their decision as well as this hybrid water heater by Voltex. Users have not only been impressed by the quick recovery time after hot water usage, but also the energy-efficient functionality that it adopts for this recovery.

Why it Stands Out to Us

Of the number of features that Voltex has provided this unit with, the one we like most is its heavy-duty anode. The high-quality components used here not only add to the functionality of the heater, allowing for its well-known fast recovery but also ensures greater durability of the product.

Who Will Use This Most

While some may think of investing in a tankless unit, others prefer the good, old tank systems that can store the heated water and provide it immediately for use. While investing in a tank heater, users need to ensure the tank is sized big enough to store enough water for their use. If you are looking for an 80-gallon tank, then no other unit will be better than this one.

Bottom Line

You will have no more hassles of a small tank and waiting for hot water recovery with this unit. This 80-gallon electric heater by Voltex will be sure to solve all the issues you had with your previous unit, providing smooth functioning that runs to provide all the hot water you need without running out.

Why it Stands Out to Us

The one particular feature of this unit that greatly stands out to us is the dual-heating element system that it comes with. The addition of an extra heating element provides the unit with enhanced functioning and also reduces the recovery time it needs, since the two elements work to heat water faster.

Who Will Use This Most

AO Smith has served to be a well-known brand in the industry, providing users with quality products. Users who trust AO Smith invest in its products time and again. If you are looking for a hybrid water heater by AO Smith, then this unit is the one for you.

As always, Rheem has loaded this unit with a number of features, but the one that stands out to us the most is its integrated LCD screen. Unlike that provided by most other standard units, this one is specifically designed with a water sensor alert and an audible alarm system. 

Who Will Use This Most

This Bradford White water heater is designed to optimize the water heating process, ensuring you do not have to wait long for the water to get heated. Such a fast functionality is offered by very few, if any, other products.

Who Will Use This Most

A number of users do not like the extra wait before they can get access to hot water, while a number of units take their own sweet time heating the water. If you want to get rid of the long wait altogether, then this unit will serve as perfect solution to this problem of yours.

All in all, this unit is one designed to provide you the most without adding to your electricity bill. In fact, its energy-efficient functionality would allow you to further save on bills, all the while providing you with satisfying performance and design. Isn’t that all we need?

Advantages and Disadvantages of Hybrid Water Heaters

A newer version of any unit is bound to hold a number of advantages over the older one, but it is also bound to have some cons, too. If you have been finding yourself indecisive about investing in a hybrid water heater, let us tell you a few of its pros and cons, and you can decide if it weighs in your favor.


Before investing in a hybrid heater, you should know the following pros:


The greatest advantage of investing in a hybrid water heater is that in a few months' time, you will be able to save the amount you spent on the unit with the reduction of your electricity bill. Hybrid water heaters are designed with a very energy-efficient functioning that is cost-effective, as well.


If you think that your old heater has lasted long enough, wait until you invest in a hybrid water heater and see how long that lasts. While a standard heater will last for about an average of ten years, a hybrid water heater lasts for about 15, providing users with a greater level of durability.

Various Operating Modes

With your conventional water heater, the unit functioned one certain way, and there is very little you could change about it. With a hybrid water heater, you get a number of operating modes to switch between, depending upon your use. This not only allows greater satisfaction but also helps in further cost reduction by putting the unit of sleep mode when not in active use.


Before finalizing your purchase, you should also know the following disadvantages:


These units may be a lot more efficient than conventional heaters, but this efficiency does come at a cost. Even though they allow you to save on bills and recoup their own price, the cost initially paid for these units is greater than that for conventional water heaters


Since older heaters did not come with a number of features, there is not much you needed to do to get them working other than the basic installation process. Since hybrid water heaters feature a number of modes and functions, users may find its use a little complex.

How to Install a Hybrid Water Heater

While using a hybrid water heater may not be rocket science at all, installing it does require slightly more effort. Since it is not a day-to-day job for a number of individuals, not everyone may be familiar with the installation process. In case you, too, have been wondering about how to do it, here is a quick guide to installing a hybrid water heater.

1. Before you start installing the unit, ensure that you have shut off the water supply and pulled the breaker for where you want to install your unit.

2. Drain the water from your previous water heater and ensure that the tank is completely emptied once you’re done.

3. Break any water and electric connections of the previous heaters. For this purpose, you may need to cut the pipe and a few wires. 

4. Once the connections are all severed, move the old unit out of its place and replace it with the new one.

5. Make the two water connections with the hybrid water heater, one that allows the hot water to go in and the other through which supplies hot water to the house.

6. Once the water connections have been made, move on to complete the electrical connections.

7. The tube through which the condensed water is discharged has to be put into the ground or drain where the condenser discharge can go. Furthermore, an air filter is put into place.

8. Once all the connections are made and their security ensured, the valves for the water are opened and the breakers are turned back on.

9. Using the display on the unit, you may set the functioning of your hybrid water heater according to your own liking.


All in all, a new hybrid water heater may serve as the perfect addition to your house. With keen consideration of the right aspects, you would be able to invest in a unit that is perfect for you, with all the right sort of features.
