5 Best Hybrid Water Heaters: The Most Efficient Water Heaters

Best Hybrid Water Heater

The hybrid water heater is perhaps the most efficient type of water heater that exists as it absorbs heat from its surrounding and uses that environmental temperature for heating the water.

Thus, the hybrid water heater drastically diminishes the amount of electricity or natural gas that it needs to heat water. This allows you to make a lot of savings on your electricity or gas bill. You will quickly be able to repay for the price of the hybrid water heater based on those savings alone.

If you are fresh on the market for a hybrid model, then we have you covered! Our hybrid water heater review below covers a few popular models in order to help you get a quality heater at a great price.

The Difference Between the Hybrid Water Heater and Other Water Heaters

Even if the hybrid water heater may look a fair bit similar to the traditional water heater, they are different types of heaters. In fact, they use an entirely different technology. Here is a quick breakdown of the main differences between the two.

Traditional Water Heater: The traditional water heater uses a copper coil that conducts water from the bottom of the water tank to the top. This copper coil is normally heated at the top since call water naturally sinks to the bottom and hot water rises to the top. In addition, the traditional water heater has a small water pump that will push water from the bottom of the water tank to the top, further helping convection to occur.

One disadvantage of the traditional water heater is that the water needs to be constantly heated or else it will lose its temperature rather quickly. This means that the traditional water heater is not very efficient in keeping water hot.

Hybrid Water Heater: On the other hand, the hybrid water heater is a new type of heater that uses an entirely different type of heating. Instead of focusing on heating the copper coil that you will find in a traditional water heater, the hybrid water heater uses an air pump that absorbs the surrounding air and extracts the temperature from that air by using a special refrigerant.

This heated refrigerant then moves to a compressor that heats it even further. Once this has been done, this refrigerant now moves to the heat exchanger that then transfers the heat from the refrigerant to the water.

One of the biggest advantages of the hybrid water heater is that it is able to keep water hot for a longer period of time and is much more efficient than the traditional water heater.

How to Buy a Hybrid Water Heater

How to Buy a Hybrid Water Heater

In order to help you find the best hybrid water heater for the money, here is a quick buyer’s guide that will show you some key points to consider.

#1. Capacity

The capacity of the hybrid water heater will depend on your need and purpose. The higher the capacity of the heater, the more water it can heat, but it also uses more electricity or gas for the heating.

On the other hand, a high-capacity model can deliver more heated water for a longer period of time. If you have a big family and your demand for heated water is high, then it is always best to go with a high-capacity hybrid water heater.

In most cases, a hybrid water heater that can deliver at least 50 gallons or more is more than sufficient for heavy-duty purposes. If you will not be using that much and looking for a heater for casual use, then you can safely go with a model that has a capacity as low as 25 gallons.

#2. Flow Rate

The flow rate is how fast the hybrid water heater is able to deliver heated water to your water outlet. This value is normally measured in GPM (gallons per minute), and for casual use, around 2.5 GPM is more than enough.

Also, bear in mind that the capacity and the flow rate go hand-in-hand. Normally, a high-capacity hybrid water heater will also have a higher flow rate than a lower capacity model.

#3. Fuel Source

There are 2 common fuel sources when it comes to the hybrid water heater. Electricity and natural gas. In North America, propane is the most common type of natural gas used by the hybrid water heater, and other types of water heaters as well.

Both of those fuel sources are excellent solutions for powering the hybrid water heater. There is no “best” here. When choosing between those 2 types of fuel sources, go with a source that is cheaper for you and more readily available.

In addition, a few top-rated hybrid water heaters provide you with the ability to convert the fuel source from electricity to gas. They do so by including a conversion kit that allows you to quickly and easily switch between those 2 power sources.

#4. Storage Space

The hybrid water heater is generally bigger when compared to a traditional heater. Therefore, you need to ensure that you have sufficient space to store it. Also, note that most hybrid water heaters need to be installed on the floor and should not be mounted on a wall due to the way they are designed and supposed to work.

#5. Easy to install

Even if you have never installed a hybrid water heater, it isn’t very difficult. Most models come with a detailed manual that will show you how to install it. Most of the time, the installation process should not be very different from how you install a traditional water heater.

How to Install the Hybrid Water Heater

How to Install the Hybrid Water Heater

Step 1 - Locate your Installation Space

Choose a suitable area for installing your hybrid water heater. You need to leave at least 7 inches clearance space between the wall or any nearby object to your hybrid water heater so that it can work efficiently and not get affected by nearby objects.

Step 2 - Set up Your Water Tank

Your hybrid water heater will need to connect to a water tank that will store the water. If you do not have a water tank and plan to connect the hybrid water heater directly to your plumbing system, then you can skip this step. If you have a tank, connect the 3/4 inch NPT inlet connector of your hybrid water tank to the outlet of your water tank. Additionally, your water tank needs to be level to the hybrid water heater or higher up but not down because it needs adequate water pressure to enter the hybrid water heater.

Step 3 - Connect to your Condensing Drain Line

Your hybrid water heater has something called a condensation line that helps heat water more efficiently. Connect the condensation drain port to your condensation drain line using standard 3/4 inches NPT fittings.

Step 4 - Connect Your Electrical Wires or Gas Line

With the above step down, you now need to connect your hybrid water heater to the fuel source. If your heater uses electricity, connected to the mains. If it uses gas, then make the connection to your gas system. You may need an extension in both cases if you are installing the hybrid water heater in a remote location in or outside the house.

Make sure you follow the manufacturer’s installation process when you do so as you may easily void the warranty if you do not install it correctly. Most hybrid water heaters come with a detailed manual that will show you how.

Step 5 - Make Some Final Adjustments

Now that you have made the proper connections, you can switch the electricity or gas on to power your hybrid water heater. Once it is powered on, your heater should have a few modes like energy efficiency, normal use, etc. Choose a setting that fits your need and purpose.

There you have it. Installing the hybrid water heater is quite easy and very similar to installing a normal water heater.

Conclusion

If you want to make a lot of savings on your electricity or gas bill, then you absolutely need the hybrid water heater. Unlike the traditional water heater, it consumes less fuel and is able to heat water more efficiently.

Additionally, this is a flexible type of heater that comes with multiple settings so as to best suit your water heating needs. Sure, it is more expensive, but it will quickly repay for itself as you will be saving a lot of money with this type of heater.
