Best Recommended Electric Water Heater Reviews
Stiebel Eltron Tempra 24 Plus
Our first entry comes from none other than German manufacturer Stiebel Eltron. If you’re worried about moisture and toxic fumes accumulating, you’ll be glad to know that this model is designed to prevent those issues — the Tempra 24 Plus doesn’t even need any venting whatsoever.
Upon first look, you’ll notice how well-designed the water heater is. It features a compact design to help you save space in your apartment or house.
You can save about a fifth of your usual electricity expenses caused by inefficient water heating. How is this possible? Well, it’s because the Tempra 24 Plus does not consume power all the time.
Only when you need to have hot water will it use up electric power. Even when it does use power, the heater uses only what it needs thanks to the self-modulating feature. You know that the heating chambers are very durable since they’re made of copper — a material praised for its excellent thermal conduction.
Some people dislike heaters because the water temperature changes fast even when they didn’t adjust anything. This model ensures a sustained temperature with its Advanced Flow Control. It keeps the water heated just enough to keep you comfortable.
- Operates in a fairly quiet manner to avoid disturbing others
- Well-designed digital temperature display
- Flow rate can be reduced to continue providing hot water even when the capacity is exceeded
- Maximum temperature is set at 109 degrees Fahrenheit to avoid water that can burn your skin
- 5.5 GPM or gallons-per-minute rate is good enough to provide two bathrooms with hot water at the same time
- Installation requires professional help due to the complex electric components
- Not all households can have this installed since it requires a 200-amp electrical service at the least
If you’re on the lookout for a small but highly efficient water heater, this one’s for you. The Tempra 24 Plus will fulfill your constant need for hot water with its high-tech features. Installing it can take some time and effort, but that’s a small price to pay for a pretty remarkable heater.
EcoSmart ECO 27 Electric Tankless Water Heater
Another impressive tankless model is the ECO 27. If the Tempra 24 Plus could reduce your electricity bill by a fifth, this heater can slash more than half of it. Compared to your standard storage tank heater, this one is smaller in terms of occupied space by up to 12 cubic feet.
So, how can the ECO 27 achieve such a high amount of energy savings? After all, both of them have a compact and tankless design. They also allow you to change the temperature using a digital control. Well, the answer lies in both the components and innovative features.
First and foremost, copper is combined with steel parts to ensure that the remarkable thermal conduction isn’t affected by any flimsy parts. Every component can be quickly replaced if it suffers severe damage.
A second factor is its self-modulating technology. Similar to that of the Tempra 24 Plus, it determines the precise amount of energy needed to heat water.
The energy efficiency of this model is set at a whopping 99.8 percent — nearly perfect. Moreover, it helps that this water heater has met the safety and performance standards of both Underwriters Laboratories (UL) and the CSA Group.
- Capable of producing almost three gallons of hot water every minute when the initial temperature is at a very cold 37 degrees Fahrenheit
- Weighs just about 17 pounds for easy handling
- Good range of temperature ranging from 80 to 140 degrees Fahrenheit to protect children from the burn-inducing hot water
- Comes with a reference chart so that you know how much hot water you can have depending on your geographic location
- You’ll have a well-written guide so that you can perform troubleshooting on your own
- Comes with a lifetime warranty but only for some parts and not for the whole product
- You need to hire a licensed worker to install the heater to stop the warranty from becoming void
If you’re okay with the relatively strict rules regarding the lifetime warranty, you will be satisfied with this water heater. The EcoSmart ECO 27 manages to be a contender for those looking for a model they can rely on in cold regions.
Ariston GL2.5 Electric Mini-Tank Water Heater
If you want a storage tank water heater without all of its bulk design occupying most of the room, get the mini-tank variant. This Ariston model can carry up to 2.5 gallons of water for immediate use. The amount certainly isn’t huge, but it’s enough for a standard sink.
Of course, you’re not stuck with only 2.5 gallons. You can have this 16-pound machine installed independently — or connect it to a bigger water-heating system. Doing the latter will guarantee that multiple people can have heated water in the bathroom or kitchen at the same time.
What’s important here is you understand the risks of using a mini-tank heater. The durability of one certainly can’t compete with bigger models.
Excessive heat can make it leak water or other substances. If you want this to last long, you must have this thoroughly checked at least once a year.
- An indicator light reveals when the water has reached your preferred temperature
- You only need a decent 120-volt outlet instead of complex wiring systems to power it
- Heated water is ready after a single second or two
- Comes with a six-year limited warranty and another one for the components
- Conducting maintenance can be very stressful due to how it’s put together
- Changing the desired temperature is difficult since it doesn’t use a digital temperature control
A mini-tank heater shouldn’t be your primary source of hot water — and that’s perfectly fine. The Ariston GL2.5 does its job fine as a compact heater under your sink. Just don’t forget to take extensive care of it from time to time.
Bosch Tronic 3000 T 4-Gallon Electric Mini-Tank Water Heater
Looking for a slightly bigger mini-tank heater than the Ariston GL2.5? Well, here’s your pick. This model still sports a very compact and modern design despite having a total capacity of four gallons.
Apart from placing this under the sink, you can also place this in a sturdy cabinet. Ever heard of a point-of-use (POS) system? This Bosch mode uses one. It’s quite simple: The water is heated near the place it will come out from. So, when you take a shower or use the sink, the heating process happens there.
What’s the point of a POS system? Its primary goal is to avoid wasting heat. If the water is heated from a primary heater located farther than this POS heater, it will lose some of its heat.
- Works with any standard power outlet
- The foam used to improve energy efficiency is CFC-free so it’s environment-friendly
- Uses a pressure relief valve to prevent excess pressure from ruining the machine
- Comes with a six-year inner tank warranty and a two-year parts warranty
- Expect this machine to have mineral deposits that you need to remove yourself the more you use it
- Safety valve might occasionally have a leak
This is most likely the best four-gallon storage tank water heater in the market. It’s clear that the manufacturer paid great attention to user experience — handling and installing the Bosch Tronic 3000 T model is far from complicated.
Reliance 6 6 SOMS K Compact
Finally, how does a six-gallon capacity sound? This is the biggest water heater in our list — yet it manages to feature a compact design.
Weighing just less than 35 pounds, the Reliance 6 can still be placed under the sink or in any recreational vehicle if you like to travel. Both inlet and outlet connections are placed on the side. This will help you place the heater in tight areas.
Like the other heaters, this uses copper to quickly heat up the water. Installation is surprisingly not hard. You don’t have to worry about corrosion since the appliance features glass linings. Other safety measures you’d find include the pressure relief valve and the temperature control valve.
- Side connections make it easier to fit the machine in narrow areas
- Comes with a six-year warranty
- Insulated with foam to become more efficient in heating water
- Six-gallon capacity ensures you won’t run out of hot water on a regular day
- Lacks a conveniently placed temperature dial
- Maintenance can be hard because of how it’s constructed
For those of you who want a hefty storage tank heater, go for this model. The Reliance heater offers enough water to last you through the day. In addition, its smart design allows it to maximize the space available in your house or vehicle.
Benefits of Using an Electric Water Heater
1) Less Riskier Than Gas Models
Think about it: If an electrical surge occurs, the likely thing to happen to an electric water heater would be for its parts to stop functioning properly. We’re also not disregarding the possibility of a water leak.
However, it’s far more dangerous with a gas-operated heater. If the gas line is damaged and a spark develops, a deadly explosion can take place. Safety features for gas models have certainly improved over the years, but it doesn’t hurt to be extra careful.
2) Energy Efficient
In most cases, natural gas is a more affordable power source than electricity. However, electric models utilize power more efficiently.
In addition, you can always buy insulation blankets to further improve the energy efficiency of your water heater.
3) Reliable Supply
What’s more likely to happen: running out of gas or electricity? More often than not, you’ll have a reliable source of electricity. It’s becoming more uncommon for homeowners to experience power outages lasting for hours on end.
Therefore, you won’t have to worry about any natural gas or liquid propane running out in your water heater.
Types of Electric Water Heaters
Tank Electric Water Heater
This is what you’ll usually find in houses. It’s primarily characterized by an insulated tank with a capacity ranging from 30 to 50 gallons on average.
In other words, hot water is already prepared and contained in the storage tank. A pipe leads the hot water to where you need it, whether it’s to the kitchen sink or bathroom shower.
Benefits of Tank Models
1) Relatively Affordable
If you have a tight budget, go for a tank water heater! The price and installation cost of a tankless model can quickly balloon to several thousand dollars.
With just $500, you can buy a fairly decent tank electric water heater and have it installed by a professional.
2) Easier to Operate and Maintain
A tank heater operates far simpler than a tankless variant. It stores and heats water before sending them out through a pipe. In effect, maintenance and repair costs will be considerably lower.
3) Quickly Provides Water
There’s practically no waiting time with a tank electric water heater. The water is already heated and waiting in the tank whether you need it early in the morning or late at night.
Tankless Electric Water Heater
A tankless model can is also called an on-demand heater. Why? As the name implies, it supplies hot water when you need it—there is no hot water stored beforehand.
So, how does a tankless model work? Well, the water simply goes through the machine as burners quickly heat them up.
The process is fast, especially if your tankless heater uses copper heat exchanges. If you remember back in your science class, copper is a great heat conductor. It also helps that copper is corrosion-resistant and highly durable!
Benefits of Tankless Models
1) Lower Utility Cost
A storage tank model has a set amount of hot water already stored. In contrast, you only have to use electricity to power up a tankless heater when you do need water to be heated.
You save on your utility expenses, and there is significantly less water wasted every single day.
2) Long Lifespan
Looking for a long-term investment? Get a tankless electric water heater. The lifespan can easily exceed 12 years and go for as long as 20 years.
We’ll be honest with you here and admit that a tankless heater is typically more expensive than a tank model. However, the amount of money you save in the long run more than justifies the initial price you pay.
3) Saves on Space
If you live in a small apartment or your house is simply cramped, this is the logical choice. The space they occupy is arguably smaller than those heaters with huge storage tanks.
There are indeed heaters with small storage tanks, but it’s the tankless model that can be conveniently installed in tight areas—you can even have the heater placed outside.
Factors to Consider Before Buying an Electric Water Heater
1) Household Size
A tankless water heater takes much less space, but you should probably stick to a storage tank model if you’ve got many people at home. After, you wouldn’t want your kids to fight over who gets to use the hot water first.
For a family of three to four people, a heater with a 50-gallon tank should be the minimum requirement. If there are five people, choose a tank with a capacity ranging between 60 and 80 gallons.
And if you’ve got a family of seven or more people, you should invest in a 100-gallon tank electric water heater.
2) Safety Features
Like any other household appliance, you need to be careful when handling a water heater.
Thankfully, there are safety features such as thermal protection, release valves, and freeze protection that make the machine less likely to malfunction.
Every purchase of a water heater includes a warranty, but some are better than others. A 15-year warranty is much better than a 10-year one. Likewise, you should look for heaters that come with parts and labor warranties as well.
Overall, there’s a lot to like about the best electric water heaters. There are no dizzying fumes to worry about. Plus, you don’t have to refill the machine with gas from time to time. Just make sure that you’ve got a power outlet and the right home electrical service.
Whether you need a space-saving tankless model or a six-gallon storage tank heater, we’re confident you’ll find the right water heater for your home.
