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 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 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.


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.
