Its 80-gallon capacity is sufficient for a family of five and more. Combining this with its remarkable first-hour delivery rating, you get a unit that is worth having in your home.
While this water heater is lightweight, I still recommend professional installation because it requires at least 75 inches of vertical space. I also find its 20-gallon per hour recovery rate at 90OF to be mediocre since I have seen products doing better.
2. AO Smith HPTU-50 Voltex
The AO Smith HPTU-50 Voltex is one of the most energy-efficient water heaters you can buy. It draws in ambient warm air to heat your water and runs on electricity when needed.
This product has four operating modes to give you exceptional control over your energy utilization. You can put it on Efficiency to use the air fan-condenser-evaporator combination to deliver hot water to your shower, kitchen sink, and more.
You will save up to 73% of your energy consumption with this mode. There is also an Energy Star certification to prove this point.
Setting the device to Electric will give you hot water fast. It is energy-efficient enough to never cause an abrupt increase in your electric bill. For the average household, setting the water heater to the Hybrid mode is like putting it on automatic. The unit activates its electric heating element when hot water demand increases.
I love the product’s Vacation mode. You can leave it for several weeks without worrying about the unit freezing upon your return. At least, you can get back to enjoying hot showers as soon as you get back from your adventures.
Do take note that this product only has a 50-gallon capacity. If you want more hot water, you might be interested in an AO Smith 80 gallon electric water heater.
I like its dual-voltage design, although I recommend plugging it in a 240-volt system. I also commend its removable air filter. You can extend your device’s service life this way.
Too bad the electronic display is small. This hybrid water heater is also heavier than others at almost 200 pounds. You may need some help installing it.
3. Stiebel Eltron ACC300 Water Heater
An 80 gallon hybrid water heater is enough to deliver hot water for a large family, especially if you take the Stiebel Eltron Accelera 300. It provides 50 gallons of hot water sufficient for the simultaneous 10-minute showering of five people. If you need more, the unit’s electric heating element kicks in to deliver the hot water you need.

This unit can also serve as a dehumidifier, a welcome attribute if you live in colder regions. You can reduce the humidity in your basement, allowing you to enjoy a drier place to perform some of your activities.
Not everything is rosy about this hybrid water heater, though. First, it is quite tall at 79 inches or roughly 6.5 feet. You also have to factor in the water pipes connected to the water tank’s top and the tank’s base height.
A more pressing concern is the unit components’ durability. Some customers complained of the evaporator coils and condenser not lasting two years. Leaks and faulty air fans are also issues. It would be nice to buy a product with very few to no problems at all.
4. Rheem MR50245 Water Heater
Many families have a Rheem water heater in their homes because of its reliability, durability, and energy-efficiency. These attributes are what you get when you install the MR50245 Marathon in your house.
This electric water heater has an energy efficiency rating of 0.90 to 0.94, translating to better water-heating savings for your family. It will only cost you less than $500 every year to enjoy readily-available hot water in your bathroom and kitchen.
I also like the product’s polyurethane insulation because it helps improve energy-efficiency while also mitigating heat loss. Fire this up today, turn it off, and the water will still be hot the following day.
It helps that the company decided to fuse its heating elements thermally. It adds a layer of safety against dry-firing. The tank also has a commendable design, using different materials to give it exceptional rustproofing and corrosion resistance. Also, it is lightweight and can be installed on your own without fuss.
While I appreciate the water heater’s energy efficiency, I wish the company did something to improve its 20-gallon per hour recovery rate. Some customers also complained about the cold-water intake air check valve’s durability and functionality. You might want to replace the component with a different check valve.
5. AO Smith HPTU-50N Water Heater
I believe the AO Smith HPTU-50N Voltex is the best hybrid electric water heater any family can ever buy. Several reasons contribute to its 73% cost-reduction performance, complete with certifications from five of the world’s top product quality organizations.
Having this unit in your home can help you save more money on water-heating than any other system. It delivers 66 gallons of hot water within the first hour, allowing your household of six to enjoy 10-minute showers simultaneously.
Putting it in Efficiency will give you the most energy savings. Its Electric mode is perfect for households who may need more hot water than its 66-gallon FHR. There is no worry about electric consumption, either. Its heating elements only use 4.5 kW per hour.
It also has a Hybrid mode ideal for families who expect the system to automatically activate its electric heating elements when needed. There is also a Vacation mode, safeguarding your unit’s integrity when you go out of town.
The digital display is pretty useful. You can set it to display either Celsius or Fahrenheit. It is also easy to check for errors because of the device’s built-in diagnostics.

If you operate a small hotel or a business that relies on large volumes of hot water, the Rinnai CHS199100 is perfect. The company designed this hybrid water heater with commercial establishments in mind, offering large volumes of water for many people to enjoy.
The Rinnai hybrid water heater uses gas as its principal energy source for heating water. You can use either propane or natural gas, whichever is more practical for you. Venting is never a problem because it allows for multiple options, including room air, two-pipe, common vent, and concentric systems.
I love this product’s water-heating performance. It is so efficient that it can heat 315 gallons of water within the first hour. Even if you have a football team using hot water simultaneously, this hybrid water heater can still deliver 231 gallons of 100-degree water every hour. Most products can only recover at 90 degrees Fahrenheit.
I also find its control panel pretty helpful. It has an easy-to-dial thermostat that lets you control its temperature between 98 and 185 degrees Fahrenheit. You can enjoy a great cup of drip coffee or French press straight from your hot water tap with this unit installed.
While this hybrid water heater has pre-assembled components, I still recommend getting a plumber to install it. It is large and heavy that no DIYer can accomplish installing on his own. It is also a commercial unit, giving you a price tag beyond the ordinary household’s reach.

The system’s recovery rate is also exceptional. Most hybrid water heaters can only recover 20 gallons per hour. This unit can provide your family between 32.4 and 42.4 gallons of hot water every hour. Cold showers will be history with this unit serving your family.
I appreciate the inclusion of an R-Tech anode rod to improve the tank’s corrosion resistance. The system also features an integrated blower that removes flue gases more efficiently. Combine this with its 100-foot long venting system, and you have a unit that is as safe to operate as any other water heater.
I also love the electronic gas control system, although I wish the company included a thermostat for setting the preferred temperature. Finding replacement parts can also be worrisome unless you source them directly from the company or its authorized retailers.
8. American Water Heaters GH-90N
Most of the hybrid water heaters we have are bulky and tall, requiring plenty of installation space. The American Water Heaters GH-90N hybrid gas water heater only needs a vertical clearance of about 50 inches and a floor area of 35 by 27 inches. It is also lighter than other brands, enabling you to install the system with ease.
Like an electric heat pump water heater, this device comes with a few operating modes to improve your energy utilization.

I am amazed at this product’s water-heating performance. You can enjoy up to 89 gallons of hot water in the first hour alone. If you have plenty of visitors in your house taking turns at the shower, this water heater delivers, too.
Plus, it can recover 45 gallons of hot water at 90 degrees Fahrenheit every hour. Never again will you complain of cold water during showers.
I like the use of the Dynaclean dip tube because it allows for more efficient water heating. It also resists corrosion to extend your system’s service lifespan. The temperature and pressure relief valve also has certification and rating from the CSA and ASME, respectively. That is additional peace of mind for you.
Unfortunately, gas water heaters are not as cost-efficient as electric systems. This product is no exception. Additionally, I find its height a bit taller than most, at about 76 inches. Do take note that you still have to make an allowance for your fittings.
10. Rheem PROE20 Water Heater
Looking at the Rheem PROE20 1 RH, you cannot help wonder if it is the same as the Rheem Performance Platinum 10-Year Tall Hybrid Electric Water Heater. The only difference is their size, with the Platinum standing taller than this unit. On the bright side, this water heater is perfect for small homes and those who want to install a water heater under their kitchen sink.
As a point-of-use water heater, you can turn this product into an integral part of your under-sink water treatment system. It meets the National Appliance Energy Conservation Act’s stringent requirements, while its components comply with UL specifications. You get a product that is of the highest possible quality and performance.
This water heater can get your hot water ready in a few hours. Its recovery rate is also comparable with other systems, ensuring you have a continuous hot water supply. The tank will last you many years, too. It has a proprietary lining that keeps corrosion and rust in check.
I am surprised to learn that many customers found the product information misleading. For example, it is a 120-volt system, not 240 volts. Its diameter is also not 16 inches, but 18-3/4 inches. While these may not seem a big deal, voltage rating and tank diameter are critical information you need to consider when buying a water heater.
Given that it only has a 20-gallon capacity, I also find the product’s price to be a bit higher.
11. Stiebel Eltron 233059 Water Heater
If you are looking to cut your water-heating expenditures by as much as 80 percent, I recommend the Stiebel Eltron Accelera 300E. This product provides one of the highest energy cost reductions you can ever imagine among modern water heaters.
The Model 233059 80 gallon heat pump water heater makes efficient use of ambient air. It features a substantially redesigned air fan that facilitates more efficient airflow. Its design guarantees an Energy Star factor of 3.39, better than the 2.5-rating of other systems.
I find its compressor motor pretty unique because of its ingenious rolling piston design. It works like a charm in drawing in warm and hot air from the external environment to heat your water. This unit can deliver almost 80 gallons of hot water in the first hour, ensuring your family of eight will enjoy 10-minute hot showers simultaneously.
While this product does not have an advanced thermostat, it sure did a fascinating job designing its digital display. The display information is bright and clear. You will never have to use your eyeglasses to read the system’s settings. Toggling between the menus is also straightforward.
Unfortunately, this heat pump water heater takes about 10 hours to heat all the water in the tank to a maximum of 149 degrees Fahrenheit, drawing in 59OF ambient air. The unit is also the heaviest on this list, weighing a whopping 297.6 pounds. It tips the scale at almost 1,000 pounds once full.
12. Westinghouse 16500W Water Heater
If you do not believe Rheem 80 gallon electric water heaters are the best for your business, you might want to consider the Westinghouse WEC080C3W165. The company designed this water heater for modern commercial establishments, giving them sufficient hot water supply for their business to thrive.
Three premium-quality, 5,500-watt rated titanium heating elements form the system’s water-heating core. These elements combine for a whopping 16,500 watts of power, allowing you to reduce your water-heating time to a few hours. You can rest assured your guests will have a refreshingly hot shower anytime.
The tank’s interior is also worth mentioning. The company ditched the traditional glass-lined design for pure 316l stainless steel. The design eliminates the need for anode rods, taking your worries about having to repair broken rods away.
I like the use of an internal fuse block that improves the device’s overall electrical safety. You can also connect it as a single-phase unit or a three-phase system, whichever works best for your needs.
Its dimensions blew me away. Most of the commercial water heaters I know are huge and bulky. This product only requires a vertical clearance of about 75 inches and a floor area of 24 inches.
Of course, its commercial quality often translates to a higher price tag. While it is more compact than other commercial units, I would still advise you to get a professional to install it. Remember, you do not want to connect the wrong wires.
What Is The Best Hybrid Water Heater/ Who This Is For
The best hybrid hot water heater offers families better cost-savings and energy-efficiency than traditional water-heating systems. It relies on two heating mechanisms to provide greater energy-efficiency. When one system cannot meet high hot water demand, the water heater activates the secondary water-heating system.
Hybrid water heaters are ideal for families living in warmer climates because the system draws in hot air from the environment and uses this to heat water. It is perfect for reducing your air conditioning unit’s workload by allowing the water heater to draw in hot exhaust from your AC.
These water-heating systems are also great for those living in colder climates. They can use the system to dehumidify their basement or any other crawl space since it draws in warm air.
How Do Hybrid Water Heaters Work
Hybrid water heaters work like other water-heating systems, with the main difference being their energy source. Conventional heaters use only one energy source, including electricity, gas, solar, and geothermal. Hybrid systems utilize any of these energy sources, but with the addition of another energy source – warm environmental air.
A hybrid system has two major components: a condenser-evaporator compartment and a secondary heating system. A fan draws in hot air from the environment and is compressed into the evaporator coils. A refrigerant in the evaporator coils picks up the heat and moves it to the heat exchanger. It is here where the system heats the water.
The second component features heating elements that connect to an electric control unit or gas burners. Suppose the primary heating element (the heat pump) cannot meet hot water demand. In that case, a control mechanism activates the second unit to deliver sufficient hot water for everyone in the family.
What Are The Different Types Of Hybrid Water Heaters
Hybrid water heaters can come in different types. However, the two most common are electric and gas hybrid water-heating systems. These products correspond to the second heating system that supports the heat pump.
An electric hybrid water heater is almost like an electric water heater, except for the heat pump’s addition at the tanks’ top. An increase in hot water demand activates the electric water heating element to meet the demand.
A gas hybrid water heater has a burner as its second heating system. It may be wise to differentiate a true hybrid water heater vs gas water heater. The former has a heat pump in addition to the gas water heating component. A gas water heater does not have this component.
Advantages And Disadvantages Of Using A Hybrid Water Heater
Using a hybrid water heater can provide you and your family with the following advantages.
- It can reduce your water heating costs by as much as 80% per year, translating to hundreds of dollars of savings.
- Hybrid water heaters are more durable than traditional water heaters, further giving you greater savings.
- Setting it up requires no significant changes or modifications to your electrical or gas system.
No system is ever perfect. Hence, some of a hybrid water heater’s drawbacks include the following.
- Hybrid water heaters are more expensive to purchase than traditional systems.
- The addition of a heat pump increases the height of the hybrid water heater tank.
- You do not get energy savings if you do not use the Eco or Auto mode.
Hybrid Water Heater Buying Guide
Taking the time to read different hybrid or heat pump water heater reviews and learning about the device type perfect for your home can help you decide which best hybrid water heater to buy. It will also help if you consider the following.
- Energy Efficiency
You will want the hybrid water heater to retain as much heat as possible and minimize heat loss over a longer period. For example, if you heat your water today, it should still be hot tomorrow. Always choose a product with a higher energy efficiency rating.
- First-hour Rating
The ideal hybrid water heater should provide you the required volume of hot water within the first hour of operation. As a rule, always pick a product with a higher first-hour rating. For example, choose a hybrid water heater with an 85-gallon FHR instead of a unit with a 40-gallon FHR.
- Recovery Rate
How fast the system can heat water after use is also important. Its recovery rate refers to the hybrid water heater’s ability to bring water temperature back to its preferred levels after use, often expressed in gallons per hour (GPH). The higher the GPH, the better is the hybrid water heater.
- Operating Modes
A hybrid water heater should have at least three operating modes.
One mode uses only the heat pump for optimum energy savings. Another mode emphasizes water heating performance using the electric or gas heating element instead of the heat pump. The third mode automatically switches between the heat pump and secondary heater, depending on hot water demand.
A Vacation mode is a nice feature that safeguards the unit when you are away.
- Physical Dimensions
In general, hybrid water heaters are taller than conventional water heating systems. These products can range in height from five to seven feet. They may have the same diameter as a traditional tank water heater.
Frequently Asked Questions (FAQs)
What are the most trusted hybrid water heater brands?
AO Smith, Rheem, and Westinghouse are all reliable and trustworthy hybrid water heater brands. You can also try the products of Westinghouse, Stiebel Eltron, and American Water Heaters. I recommend checking out the individual hybrid electric water heater reviews for each brand before making any purchasing decision.
Are hybrid water heaters more energy efficient?
In theory, hybrid water heaters are more energy-efficient than other water-heating systems. You must understand that the system uses two different water-heating mechanisms. The first mechanism uses hot or warm air from the external environment, which is free. The only energy used is the one that runs the compressor.
A secondary heating system kicks in only when the hot water demand exceeds the heat pump’s hot water supply capability. Only when this event occurs will you incur substantial energy expenditure.
If you are the type of household that does not use plenty of hot water, there might never be a need to activate the system’s electric or gas component. Hence, you will only use nominal wattage for running the compressor. The result is higher energy-efficiency and cost-effectiveness.
What size hybrid water heater do I need?
Check the product’s first-hour rating. It should be within 1 to 2 gallons of your hot water peak-hour demand. If your peak-hour hot water demand is 20 gallons, a hybrid water heater with an FHR of 22 gallons will suffice.
How to care and clean?
Caring for your hybrid water heater entails the same procedure as any other water-heating system. You must check all connections for signs of damage and wear that can be the source of leaks. If you have removable components, you can clean these before replacing them individually.
It is also a good idea to drain and flush your hot water tank at least once every six months. If you want to have a lesser frequency of tank drainage, you might want to include a water softener and a sediment pre-filter before your hybrid water heater unit.
Where to buy?
Most people buy their stuff from Amazon because it is more convenient. The e-commerce giant has an extensive collection of hybrid water heaters with different specs and features for your needs. Plus, the reviews can provide you a glimpse into these products’ real-world performance.
Other noteworthy e-commerce platforms to buy your hybrid water heater include Lowes, Sears, Home Depot, and eBay. The manufacturer’s official website is also a good place to buy a hybrid water heater. They can also direct you to an authorized retailer or dealer nearest you.
The best hybrid water heater gives you as much as 80 percent energy savings. It has enough operating modes to let you pick the right one for your family, depending on your prevailing needs. While it may be more expensive than your usual, the ideal hybrid water heater should still be cost-effective in the long run.
