11 best electric hotwater heaters
Electric hot water heaters, also known as electric water heaters, are a common and efficient way to provide hot water for residential and commercial applications. Here's what you need to know about electric hot water heaters:
Basic Function: Electric hot water heaters use electricity to heat water stored in a tank. The water is kept at a set temperature, ready for use whenever a hot water tap is turned on. They are available in various sizes to accommodate different hot water demands.
Types of Electric Water Heaters:
Conventional Tank Water Heaters: These are the most common type of electric water heaters. They consist of an insulated tank that holds a specific amount of hot water (usually 30 to 80 gallons) and an electric heating element at the bottom. When the hot water is used, the tank refills and reheats the water.
Tankless (On-Demand) Electric Water Heaters: Unlike tank water heaters, tankless electric water heaters do not store hot water. They heat water on demand as it passes through a heating element. This can be more energy-efficient as there is no standby heat loss, and hot water is never depleted.
Energy Efficiency: Electric hot water heaters can be energy-efficient, especially if they are well-insulated and have a high Energy Factor (EF) rating.Tankless electric water heaters are known for their energy efficiency because they only heat water when needed, reducing energy consumption.
Sizing: Choosing the right size of electric water heater is crucial to ensure an adequate supply of hot water. Factors such as the number of people in the household, peak hot water demand, and the incoming water temperature should be considered when selecting the appropriate capacity.
Installation: Proper installation by a qualified plumber or technician is essential for the safe and efficient operation of an electric water heater. This includes ensuring the electrical wiring, plumbing connections, and venting (if applicable) are installed correctly.
Maintenance: Electric water heaters require regular maintenance to prolong their lifespan and maintain efficiency. This may include flushing the tank periodically to remove sediment buildup and checking the heating elements for corrosion or wear.
Safety Features: Electric water heaters typically come equipped with safety features, such as a temperature and pressure relief valve (TPR valve) to prevent overpressure and overheating.
Cost: The cost of an electric water heater varies depending on the type, size, and brand. Tankless electric water heaters tend to have a higher upfront cost but can offer long-term energy savings.
Environmental Impact: The environmental impact of electric water heaters depends on the electricity source in your area. If your electricity comes from renewable sources, such as solar or wind, the environmental footprint can be lower compared to fossil fuels.
Warranty: Electric water heaters often come with warranties that cover parts and tanks for a specified period. It's essential to understand the warranty terms when purchasing a unit.
In summary, electric hot water heaters are a reliable and efficient way to provide hot water for various applications. The choice between a conventional tank water heater and a tankless electric water heater depends on your specific hot water needs and energy efficiency preferences. Proper sizing, installation, and maintenance are key to ensuring the system operates effectively and safely.

Product description
This Smart Technology electric tankless water heater is configured as a "whole home" model for climates where incoming water temperature is 67°F and above. This model is well suited for heating up to 2-Gallon per minute, which is the equivalent of one shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 67°F and an output setting of 105°F. Digital Temperature Control allows you to set your temperature in increments of 1 Degree. This model can also be used in colder climates as a Point of Use for a sink or other low flow application. All tankless water heaters are sized based on flow rate and temperature rise, and there is a direct relationship between the two. So if used in a cold area requiring a high temperature rise, it will be more limited in the amount of fixtures (gallons per minute) it can heat at one time compared to a warmer climate. When sized properly this water heater will provide endless hot water and only consume the energy needed, giving the user complete control. Prior to purchase and installation please verify this model is the right size for the expected demand and electrical requirements. The ECO 11 requires a minimum 125 amp electrical panel for installation with 60 amp double pole breaker connected to set of #6 awg wire. Plumbing connections are 1/2" compression fitting with the option of 1/2" NPT adapter included. For additional assistance please feel free to contact our support center at 877-474-6473.
NOTE : 11Kw at 220 is equal to 13kw at 240. .Activation Flow : 0.3 GPM

User questions & answers
Question: | Ours has only been in service for less than a year - will not adjust temperature to anything above 85 Deg. F. What do you think is the problem ? kds |
Answer: | My only guess is that the rheostat (variable resistor) that the temperature adjustment knob is attached to may be faulty. If that isn't it then I don't know. Sorry. |
Question: | The warrenty says that this unit must be installed by a licensed electrician and plumber, for them to honor the "life time warrenty." why |
Answer: | Hello Bob, The reason is the same as why an innumerable number of gadgets around the world have that little "warranty void if removed" label. Because getting inside of one requires a certain level of training and expertise. Same with this unit. GadgetsGo is an authorized Ecosmart dealer. Kind regards,HenryGadgetsGo |
Question: | My house is wired 110V. What additional items do I need to purchase for the conversion |
Answer: | Just to expand slightly on prior answers, normally a residential service feed is 240 volts between the two incoming hot legs. There is also a neutral leg, which (hopefully) has zero potential with reference to ground. The voltage between either one of the hot legs and the neutral leg is 120 volts. The 120 volt circuits in your house are connected to one or the other of the two hot legs, and only one. An attempt is made to assign circuits to the two hot legs in a way that will roughly balance the load between them. The other side of a 120 volt circuit is connected to the neutral leg. There is additionally a safety ground run with the circuit, which also ties into the panel. Certain devices require more power (work product of current and voltage) than is practical to deliver using a 120 volt circuit. Common examples are your clothes dryer, and your electric stove. These devices are powered by both hot legs, with a difference in potential of 240 volts. This water heater is also such a device.STRONG BUT FRIENDLY WARNING: If you did not already know this, please don't make wiring this water heater your learning opportunity with electricity. Hire someone who knows how to do it right. Cutting corners, especially with higher currents and voltages, can lead to equipment damage, fire, and electrocution. Electricity is not magic, and you can certainly learn how to do many common wiring tasks safely on your own, but today is not the day to begin that journey. You need properly sized components, properly installed, and connected to an adequate service. Also, if you really, really foul up, you could conceivably wind up making that morning shower more energizing than you ever imagined, if you get what I mean. So newly aspiring electricians should go fix their grandmother's favorite table lamp instead. Once they have that working they can use it to to start reading books about electricity, residential wiring, and eventually, books about this stuff: http://amazon.com/s/ref=nb_sb_ss_c_0_8?url=search-alias%3Dstripbooks&field-keywords=nec+code&sprefix=nec+code%2Caps%2C164 . Of course, you still have to know not to nick conductors when you strip them, and other trade craft like that ; ) . Like almost everything in life that is fun, electricity will hurt you. Sort of like all those people you dated for a while, and then wished later you had never met. |
Question: | what amp breaker is required |
Answer: | The National Electrical Code requires conductors and overcurrent protection to be sized at 100% of the manufacturer's branch circuit recommendation for tankless electric water heaters. A 60 amp breaker is the same price as a 40 or 50, it is the wire that costs more. #6 AWG wire is required for a 60 amp circuit. If you undersize the wire it could overheat and catch fire. Protect your family and follow the manufacturer's sizing for this, or any other, electrical device. Your family's lives are worth the extra money. |

3 Smart Steps for Endless Hot Water
Step 1: Determining your average inlet water temperature is important, this allows you to determine how well your unit will perform in your desired location. A lower inlet water temperature will require a higher kilowatt product.
Step 2: Next you will determine how many applications your unit can run simultaneously at your chosen location inlet water temperature. Tankless electric water heaters are sized for maximum simultaneous use, not maximum fixtures in your home.
Step 3: Determining specifications and electrical infrastructure is important because without the correct infrastructure your unit may not fit into your breaker panel.

User questions & answers
Question: | What is the recovery time if the 7 gallons of hot water is used |

Question: | Can I reduce the pipe's size from 3/4 in to 1/2 in without any negative effect on the unit |
Answer: | No harm to unit.....Max water flow will be reduced a little. |
Question: | Can i use this to replace a small rv hot water heater |
Answer: | Yes, but realize that it's electric and draws quite a few amps, most rv water heaters are propane. |
Question: | The Manual request for the ES8 a 20 Amp breaker and 12GA wire. The wattage however is 1440 with 12 Amps. Why then 20 Amp breaker and not |
Answer: | I would use a 20 amp circuit with 12 ga wire but there are no inrush concerns with a resistive load. A heating element does not have a higher initial current draw like a motor. It draws 1440 watts or 12 amps at 120v. Since 14 ga wire must be fused for 15 amps, this device by itself is already at 80% of the circuit’s capacity. |

User questions & answers
Question: | How is it that this is energy efficient if it constantly maintains a heating temperature that you can use on demand? Is there an off/on switch |
Answer: | Most rinnai tankless weather it is out door or indoor, have a control board to adjust temp and either on or off |
Question: | I connected the water in the water heater already. But the pressure didn’t pumt the water to the sink |
Answer: | It can definately be out doors in freezing temps, tho power failure arent good for it while in a freeze, tho keep in mind it will use alot more energy for frost protection, indoor units are safer amd more efficient in this case |
Question: | Can I connect the water intake on this unit from the hot water supply from my house water heater? The house heater is very far from kitchen sink |
Answer: | I bought model V65EN. It came with a wired digital controller. The installer did not run the wire into the house and mount the controller indoors. He simply set the controller at 120 degrees and left the controller inside the unit. If I want to change the temp, I have to take the cover of the unit. |
Question: | Will this work for an outdoor shower |
Answer: | Good place to check for info like this is Wikipedia. Here is what they say: Energy efficiencieseditMore tangible cost savings are defined when comparing the energy efficiencies of gas heaters with low NOx emissions with conventional flued types. Gas heaters with emission problems are flued and inherently lose substantial energies in the form of hot flue gases to the atmosphere. In addition, the choice of placement of flued heaters is greatly impaired due to flue installation restrictions.In contrast, dedicated low emission gas heaters do not require a flue system. Furthermore, with the introduction of oxygen depletion sensors and thermostatic controls, they do not place critical reliance on ventilation as previously was the case. These heaters can be positioned more conveniently and centralised to affect optimum warm air distribution. By definition unflued low NOx gas heaters are 100% efficient as all heat energy released from the flame is converted to useful heat.Hope this helps. June |

Hot water on call
Waiting for hot water at a sink located far from a primary heating source can be frustrating. Only having access to cold water from a sink is just not useful, and plumbing a hot water line to every sink in a home or business requires time and money. To get hot water where it’s needed, when it’s needed, a better solution is to use the BISELONG: a point-of-use electric mini-tank heater. This heater can supplement a primary water heating source, or be used under a single sink and double sink. In fact, the BISELONG can be used for three different applications: as a sole water heating source for a single sink, as a supplement to an existing heater located far from the sink, and as a buffer installed in-line with tankless water heaters that experience intermittent cold water, also known as 'cold water sandwiching'. No matter the configuration, there’s minimal stand-by loss from this premium mini-tank water heater.
INSTANTLY HOT WATER
As soon as you open the tap, the water flows with your desired temperature. The water is only heated in the amount and for the time you actually need it.
ENERGY EFFICIENT
It saves energy by producing hot water only when needed. Instant hot water flows out at anytime you need.

Product description
This Smart Technology electric tankless water heater is configured as a "whole home" model for climates where incoming water temperature is 62°F and above. The ECO 18 is capable of heating over 2.5 gallons per minute, which is the equivalent of one water saver shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 62°F, and an output setting of 105° F. Two showers emitting no more than 1.5 gpm each can be run simultaneously when incoming water temperature is above 70° F. Digital temperature control allows you to set your temperature in increments of 1°. All tankless water heaters are sized based on flow rate and temperature rise, and there is a direct relationship between the two. So if used in a cold area requiring a high temperature rise, it will be more limited in the amount of fixtures (gallons per minute) it can heat at one time compared to a warmer climate. However, when sized properly it will provide endless hot water and only consume the energy needed, giving the user complete control. Prior to purchase and installation please verify this model is the right size for the expected demand and electrical requirements. The ECO 18 requires a minimum 150 amp electrical panel for installation with 40 amp double pole breakers connected to sets of #8 awg wire. Plumbing connections are 3/4" NPT. For additional assistance please feel free to contact our support center at 877-474-6473.

User questions & answers
Question: | How do know which size to buy? We will supply two bathrooms, dish washer, clothes washer. What size should I choose |
Answer: | I noted someone below stating they got the largest one and they can only run one water source at a time. My guess is they installed it wrong by not getting the electric hooked up right, or maybe the unit was just defective, or they live in Alaska. I went under size with an Eco 27 a few years ago because that’s all my electric panel could handle. We have zero issues in the summer. During winter months we can only run one shower at a time and have to slowly fill a tub (maybe 3/4 fill speed). To save as much money as I am on electric bill and have unlimited shower lengths (only 1 person at a time mid-Dec to mid-March) is totally worth it. On here today because I’m thinking of upping my panel size so was thinking of going with a larger one now. Regardless, CCRC’s experience with the largest unit not working is nothing like the experience I’ve had, and again I intentionally undersized mine for the house. The website has a clear chart to explain size you need based on number of water fixtures in your home and ground water temperature. |
Question: | Can this unit supply a 3,700 sq foot home with 3 1/2 baths |
Answer: | In the lower states it can, but in the northern states, multiple simultaneous users, it will be overloaded. If you can afford a 3,700 square foot home, then you can place a unit in each appropriate demand zone and be very glad you did. I love mine, live in KY, get great supply when the water is above 60 degrees, and then it slows the flow as the temperature drops. I have dishwasher, washing machine, garden tube, 2 showers, 3 sinks and 4 people. It is better than great in the summer, okay spring and fall, and we are conservative in the winter. |
Question: | What is the power consumption of this tank-less heater |
Answer: | The instantaneous power consumption while the hot water is running is quite high (up to 18kW or 27kW depending on which model you’re looking at on this page). However, when no hot water is being used, the power consumption is 0 (or a minuscule amount to run an LED light or something). The total power consumption over the course of several days or longer should be much lower than a tank heater but the short term power usage while the heater is making hot water will be much higher than a tank heater. It’s just that the unit sits idle most of the time while a tank heater will use power fairly frequently even when no hot water is needed as the water in the tank cools off over time and needs to be re-heater fairly constantly |
Question: | remote |
Answer: | This unit does not have the ability to have a remote temperature control. |

User questions & answers
Question: | Can this directly replace a 40 gal tank heater with a 30A double pole breaker? What are power requrements |
Answer: | No it can't. RTEX-24 requires 3 sets of wire and ground, and it needs 3x 40amp breaker. That's a total of 120amps |
Question: | Can you use the 10/3 for one of the cicuits |
Answer: | No. It requires three legs of 8-2. |
Question: | Can the unit operate as a rtex-18 if i only hook up 2 of the elements? because i only need the 18 specs as of now but would like the option to upgrade |
Answer: | Actually you can do this but you must be careful on which circuits are connected. Rheem says the elements are activated from right to left as power is required. The right most element connection also provides power to the control so this must always be connected. If the very left element is left disconnected, you will only get 2/3 of the rated power on a 3 element unit. |
Question: | Why are 2 answers for the breaker requirements. Is it 3 double 40 or 3 double 60 amp |
Answer: | If the unit draws 40 amp. you need a 2 pole 40 amp breaker 2 #8 wires good for 40 amp and 1 # 10 wire for a bond. Now if the unit draws 60 amps you need 2 # 6's good for 65 amps. A 2 pole 60 amp breaker and 1 # 8 for a bond( ground wire). |
