When rising heating bills have turned into your headache and limited hot-water has become a matter of discord, hybrid water heaters are the only apposite solution. Hybrid water heater or heat pump water heaters are the fusion of electrical, water, and gas technology.
This time-cutting technology is 3.5 times more efficient than those traditional water heaters. A single unit saves $300 per year as it uses heat from surroundings and utilizes electricity to transfer heat rather than generating. These heaters take good care of hard water too. All these benefits are the reason why hybrid water heaters have become a top-notch choice for consumers nowadays.
So, if you want to shift the gear to an upgraded water heater, a hybrid water heater is the most viable decision. With the superfluous hybrid water heaters available out there, it is difficult to rebuff and direct your mind towards one. A lot of time and effort is needed to research hybrid water heater reviews.

Factors to Examine in a Hybrid Water Heater
In the case of hybrid water heaters, several parameters come into the role that helps you to anticipate the service quality you are going to attain. So, in this portion of the content, we have piled up those factors that will help you to make a thrifty purchase.
Efficiency or Energy Factor
You can assume the level of water heating and savings of electricity bills that the hybrid water heater will offer from the efficiency. Of course, there will be no unit that will offer 100% efficiency. Hybrid water heaters generally have an efficiency of around 94-99.8%. So, try finding something with the closest efficiency to 100%.
The rate of water heated with the lowest energy consumption is the energy factor, another factor relevant to efficiency. Higher energy factor means lower energy consumption. A quality hybrid water heater should have an energy factor of around 0.98. The closer the energy factor to 1 the better is the performance.
A good hybrid water heater unit will give you control over temperature, efficiently ensuring your comfort and flexibility of use. For example, the feature of the adjustable thermostat (typically 10 ft length) provides hot water with proper temperature according to your need.
Also, some of them feature a digital temperature control system in between some range, remote control, or multiple temperature settings for convenience. So, something like this makes the water heater more reliable and flexible to you.
For safety, manufacturers of hybrid water heaters introduce many safety features. Auto-cut off and overheat protection are some examples of them. Having any of these features in your hybrid water heater is never a waste. Also, carefully go through the reviews to check if there is any complaint about hot water leakage.
The flow rate is defined by the GPM (Gallons Per Minute) rating. This is a measure that tells how fast the heated water will be delivered to the outlet. Typically, hybrid water heaters are designed with a flow rate of around 0.5-9.5 GPM. 2.5 GPM is considered to be more than enough.
Size and Weight
For easy setup and installation, water heaters need to be a little compact. Also, it is normal to have limited space in households where anything bigger may make you feel hassled. Weight and dimension are important factors also in the case of wall mounting.
By examining the dimensions, you can ensure that the unit will fit the space available before purchase. Hybrid water heaters normally weigh around 4 to 150 pounds.
Hybrid heaters come as both tank and tankless water heaters. If the water heater is featured with a tank, it is important to scrutinize the material and capacity of the tank. Stainless steel or glass-lined tanks resist corrosion and avoid any build-up inside.
If you have a large family, it is obvious to need a large tank to get a large supply of hot water for a longer period. But, you have to keep in mind the larger the tank the heavier the unit will be and in case of limited space, this can put you in difficulty. These tanks can have small like 4 gallons or huge like 80 gallons capacity.
The display is another beneficial feature offered by many manufacturers of hybrid water heaters. The display should be straight-forward to use and read. This is very helpful for setting the temperature and has a clear idea about the current temperature of the water.
In manuals of hybrid water heaters, the installation requirements are provided. The required ampere rating of the electric panel, circuit breaker, wire size, and type varies unit to unit. A unit may need 100-125 amps electric panel, 30-60 amp rated breaker, 6-10 AWG wire.
So, you have to make sure you can fulfill the requirements before buying one. Also, the installation process and wiring should not be much complicated. If the process is too complex, you should contact an experienced plumber.
In the case of hybrid water heaters, natural gas or electricity are the sources you are going to need. A few of them have the facility of source conversion. So, go for the unit that will run with the source available and optimal for you.
Hybrid water heaters suck heat from the surroundings to warm up the water. So, the surrounding temperature is a vital parameter for the operation of the heater.
In the specification, the optimal temperature rating is provided below which the unit will not work. Hybrid water heaters do not function below 57°F or 67°F. If you live in a region with a cold climate, you have to make sure you can provide the optimal temperature by conditioning the space to make the unit work.
Range of Temperature
Last but not the least, the temperature limit should be considered. Manufacturers provide a range showing the minimum and maximum temperature of hot water produced.
For example, a unit of hybrid water heater may have a temperature range of 110-150°F. This information will help you to anticipate the highest temperature you are going to get from the unit.
Frequently Asked Questions (FAQs)
Q: How durable hybrid water heaters are?
Ans: Hybrid water heaters offer a longer lifespan of around 13 to 15 years.
Q: What is the minimum temperature of the surroundings for a hybrid water heater to work?
Ans: Hybrid water heaters are not effective under 25-30°F.
Q: Is a hybrid water heater noisy?
Ans: A hybrid water heater typically creates 55dB sound, which is pretty lower than the noise of a hair drier. If a certain one seems to cross that noise limit especially by making a popping sound, you should pay heed since heaters explode due to trapped water pockets.
Q: What happens if you use a hybrid water heater in winter?
Ans: If it is placed in a conditioned space, this will increase heating bills and create cool and dry air. In winter, they should be placed in unconditioned or semi-conditioned space.
