14 best inline hot water heater electric

An inline hot water heater, also known as a tankless or on-demand electric water heater, is a device used to heat water as it flows through the unit. Unlike traditional tank-style water heaters, which store and heat a large volume of water, inline electric water heaters heat water only when it's needed. Here are some key points about inline hot water heaters:

  1. Energy Efficiency: Inline electric water heaters are known for their energy efficiency. They only heat water as it is required, which eliminates the standby heat loss associated with tank-style water heaters. This can result in significant energy savings over time.

  2. Space-Saving: These units are typically compact and wall-mounted, freeing up valuable space in your home compared to bulky tank-style heaters. This is especially beneficial for smaller living spaces.

  3. Endless Hot Water: Because they heat water on demand, inline electric water heaters can provide a continuous supply of hot water. You won't run out of hot water during long showers or when multiple appliances are in use simultaneously.

  4. Installation Flexibility: Inline water heaters can be installed at the point of use, such as under sinks or near showers, which reduces the time it takes for hot water to reach the tap. This can further conserve water and energy.

  5. Temperature Control: Most inline electric water heaters come with adjustable temperature controls, allowing you to set the desired hot water temperature.This provides more precise control over your water heating needs.

  6. Maintenance: These units generally require less maintenance compared to traditional tank-style heaters. However, periodic descaling may be necessary in areas with hard water to prevent mineral buildup.

  7. Cost Considerations: While they can be more energy-efficient in the long run, the initial cost of purchasing and installing an inline electric water heater can be higher than that of a traditional tank-style heater. It's important to weigh the upfront cost against long-term energy savings.

  8. Electrical Requirements: Inline electric water heaters typically require a dedicated electrical circuit with the appropriate voltage and amperage capacity. Ensure your electrical system can support the unit you choose.

  9. Flow Rate: The flow rate of an inline water heater is an important consideration. It determines how much hot water the unit can deliver at a given time. Choose a unit with a flow rate that meets your household's needs.

  10. Safety Features: Modern inline electric water heaters are equipped with safety features like overheat protection and pressure relief valves to ensure safe operation.

When selecting an inline hot water heater, it's essential to consider your household's hot water demand, electrical capacity, and space constraints. Proper installation and maintenance are crucial to ensure the unit operates efficiently and safely.

EcoSmart

Based on 2 reviews Check latest price

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.

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: Is it necessary to connect an expansion tank to this heater (for safety purposes)? It states something to that effect in the user manual
Answer: The expansion tank for this heater is not required. Most people already have these installed in their homes but if not then it would be Ok without it as there is a pressure relief valve on top if something happened. GlobalTowne is an authorized Bosch distributor.
Question: would this be able to supply a shower
Answer: A standard flow shower head is around 2.5 gallons per minute. A low flow head is around 1.5 gallons per minute. The recovery rate for a 90 degree temperature rise is 6.8 gallons per hour! So even the 7.5 gallon unit would only provide 4 minutes of shower time before the temp dropped off dramatically. (even at the low flow rate..)
Question: Can be used "in-line with a large hot water source"? Would it help a large bathtub that runs out of hot water before it gets full from main tank
Answer: If your bathtub is bigger than your main heater tank, this unit isn't going to do much for you. It will add 2.5, 4, or 7 gallons to the capacity of your main tank, depending on which Bosch unit you buy. The 7 gallon unit requires a specially wired circuit. You will also get a little bit of lukewarm water that was in the line between your main heater and the Bosch unit. Unless your main tank is awfully small and your bathtub massive, the 4 gallon unit should work for you. Maybe a demand type thankless heater in your bathtub hot water feed would be a better choice, but be careful to size it properly for your desired flow rate and temperature rise. Also a tankless is likely to require special wiring.
Question: When this heater is connected to the hot water line, what happens with the cold water that was sitting in the pipes
Answer: When the tap is opened, the hot water in the unit flows out. The colder water that was sitting upstream of the unit, enters the unit to be heated. If the tap remains open, the newly heated water flows out, being replaced eventually, (depending on the distance to the main water heater), with the water from the main water heater. You will probably set the unit temperature to equal the main water heater temperature, if you want to keep a constant temperature, but other scenarios are possible.

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.

Question: What is the recovery time if the 7 gallons of hot water is used
Answer: I have the 4 gallon tank and it is not too bad for the reheat
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: Can the flow rate be adjusted up from 0.5gpm to say 1gpm or 1.5gpm (understood that the output water will be corresponding less hotter)? thanks in adv
Answer: This is a 199,000 btu model, a 3/4" gas line is required to have sufficient gas supply.
Question: degree water going in what degree will be at the tap
Answer: rinnai recommends the GTK03 Grundfos kit for this unit
Question: are any of these tankless water heaters plug in
Answer: I think, you need buy a WiFi module, call Rennai and ask. Circ-logic did not work for me, I had to install re circulation pipe. Because of the high minimum flow requirements, this unit did not work with any regular re circulation pump, so wasted money buying a Watts pump. And paid double for the labor. Rennai told me that I should have bought their thankless heater with re-circulation built in.
Question: Would you recommend this model for a shower in a guest bathroom
Answer: IT CAME WITH ADAPTERS ON THE TOP. NO PIPING.

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: This product is fixed flow, which means that the output temperature rise of this product is determined by flow rate of the application. This chart gives you the expected temperature rise for various sink flow rates from 0.5 to 1.5 gallons per minute.

Step 3: Determining specifications and electrical infrastructure is important because without the correct infrastructure your unit may not fit into your breaker panel.

3000W Mini Electric Tankless Instant Hot Water Heater with LCD Display for Home Bathroom Kitchen Washing US Plug 110V

Common Faults and Solutions:

1. Under normal power-on conditions, the water flow turns on, the water heater displays the temperature, but the temperature does not rise, there are 2 possibilities: the first is that the temperature control switch (overheat protection switch) inside the water heater has tripped. Control switch, it can be restored. The other is the heating tube failure, replace the heat tube

2. If there is a display of no heating, the display shows rotating, but no temperature is displayed, indicating that the water flow has not passed through the water heater, or the water pressure is too low, and the water pressure needs to be adjusted; , Then check the water heater inlet turbine, it may be that the turbine is stuck, causing the water heater to not start.

3. It is recommended that the length of the water heater inlet pipe should not exceed 3 meters. If it exceeds, there may be a water pressure difference due to the length of the water pipe, and the water pressure is not enough to start. (If the water tank is used for water, the water tank is required to be placed higher than 10 meters to make the water pressure Reached the start value)

4. The display shows E1, E4/E5 means temperature sensor failure, first cut off the power, run the machine with cold water, and then power on; the heating tube failure displays E2, means the heating tube needs to be replaced.

Water Temperature

CAN this unit be connected inline with existing hot water line?

ANWSER: It is recommended not to use it in series with other water heaters. If it is installed on a hot water pipe, the water heater will reheat to above 60 degrees. There is a 60-degree over-temperature power failure inside the machine. After the power is off, the temperature control switch in the machine will jump. If you want to restore manually, you must open the back cover of the water heater machine. There is an overheat protection switch button next to the heating pipe. It can be restored by pressing it. If you do not go to the restore button, the water heater will not work and heat, so we generally do not recommend installing it in the heat The water pipe is directly installed on the cold water pipe. It is recommended that the inlet water temperature should not exceed 30 degrees

CAN we set two of these up would 1 preheat water to warm & the other heat it to hot for higher temperatures at higher flow rates?

ANWSER: NOT recommended, when two water heaters are used together, it will reach 6000w, and there will be high requirements for wires. For safety, it is not recommended to use this.

Question: Can I use the Rinnai V65EP in Denver, Co? Temperatures during the winter can get below zero
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: Does this unit come with controller? rinnai tech said i needed a mc-91-2us controller? do i need to buy separate
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: What does the "Low NOx Mean
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

Question: can i vent this thru a masonry chimney
Answer: It needs to be ported outside.
Question: What is the highest temperature achievable from this water heater? Will it produce temperatures in excess of 150 degrees F
Answer: Assuming you have everything hooked up correctly, at 3.5 GPM, the MAX TEMP will be NO MORE THAN 55 degrees ABOVE THE TEMPERATURE OF THE INCOMING WATER. For example, if the incoming water temp is 50 degrees in the winter, then the max winter temp will be 105. In the summer, when the incoming water is 65 degrees, the max summer temp will be 120 degrees. This is the way ALL demand heaters work. Be SURE to check the TEMPERATURE RISE specification on ANY demand heater to know what it is truly capable of. If the TEMP RISE is specified at 3GPM, and you try to set it higher, it may CUT BACK THE FLOW RATE to achieve the higher temp, but it will NEVER exceed the TEMP RISE spec.
