12 best instant hot water heater for rv

An instant hot water heater for an RV, also known as a tankless water heater or on-demand water heater, is a compact and efficient appliance designed to provide hot water on-the-go for recreational vehicles. Here's what you should know about these RV water heaters:

  1. Operation:

    • Unlike traditional water heaters that store and continuously heat a specific amount of water, RV tankless water heaters heat water only when needed. They use a heat exchanger to warm the water as it flows through the unit.
  2. Size and Portability:

    • RV tankless water heaters are typically smaller and more compact than conventional tank-based heaters. This makes them well-suited for the limited space available in RVs.
    • They are designed for easy installation and can often be mounted on the exterior of the RV or in a small utility compartment.
  3. Energy Efficiency:

    • Tankless RV water heaters are known for their energy efficiency because they only heat water as it's required.This eliminates the standby energy loss associated with traditional tank heaters.
    • They can be powered by various energy sources, including propane, electricity, or a combination of both.
  4. Flow Rate:

    • The flow rate of an RV tankless water heater determines how much hot water it can provide at a given time. Different models offer varying flow rates, so it's important to choose one that meets your specific needs.
  5. Temperature Control:

    • Many RV tankless water heaters come with adjustable temperature controls, allowing you to set the desired hot water temperature to suit your preferences.
  6. Installation:

    • Installing an RV tankless water heater typically requires some basic plumbing and electrical work. It's essential to follow the manufacturer's instructions and, if necessary, seek professional installation.
  7. Ventilation:

    • Propane-powered RV tankless water heaters require proper ventilation to ensure safe operation. Adequate venting is crucial to expel combustion byproducts.
  8. Maintenance:

    • Routine maintenance may include descaling the heat exchanger to prevent mineral buildup, inspecting and cleaning the burner (for propane models), and checking for leaks.
  9. Benefits:

    • Instant hot water: RV tankless water heaters provide hot water quickly and efficiently, eliminating the need to wait for a tank to heat up.
    • Space-saving: They take up less space than traditional water heaters, freeing up valuable RV storage.
    • Energy savings: Tankless heaters can be more energy-efficient and cost-effective over time due to reduced energy consumption.
  10. Considerations:

    • Consider your RV's energy source (propane, electricity, or both) and your hot water usage when choosing a tankless water heater model.
    • Ensure that the unit you select is suitable for the climate and altitude where you'll be using your RV.

In conclusion, an instant hot water heater for an RV is a space-saving and energy-efficient solution for on-demand hot water while traveling. It offers the convenience of hot water without the need for a bulky storage tank, making it a popular choice among RV enthusiasts looking to maximize comfort and efficiency on their journeys.

User questions & answers

Question: Does this have a winter use device (wud
Answer: 24W
Question: Does it run on both electric or propane
Answer: It requires 60Hz/110VAC and it is rated at 24W. Unfortunately for me, the HE is not listed by a nationally recognized testing lab, so the installation requirements are much more stringent. In my case the National Fuel Gas Code requires more clearance around it than I have in my water heater closet. So I returned mine.
Question: Can this be used year round in nc where outdoor temps can dip down to 0f? the inside of camper would stay heated
Answer: the cup holder is pretty large, so I think basic 12oz cups would fit fine
Question: i have a 16x16 open hole what door do i need
Answer: Yes, the cup dispenser is removable

EcoSmart ECO 11 Electric Tankless Water Heater, 13KW at 240 Volts with Patented Self Modulating Technology

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: 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: 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.

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.

User questions & answers

Question: What size is the exhaust
Answer: As long as the water can flow, the water heater can work normally. But in practice, if the temperature is lower than 5 degrees(41 fahrenheit), the pressure in the gas cylinder will decrease, and the gas cannot be supplied to the water heater normally, resulting in the water heater not working properly.Hope the information can help you.
Question: I just want to verify if this can be installed indoors
Answer: I am afraid it doesn't work with natural gas,just for propane.
Question: Is it correct that this cannot run longer that 20min
Answer: The unit must be installed at a ventilated place.Usually we don't suggest to install it indoor.
Question: Is this on demand. Does it turn on when water is started or do you have to turn it on at every use
Answer: 1.12 volt power supply for the water pump.The 12V power source can come from the car battery.We provide a booster cable to connect the pump and the car battery. 2.The propane water heater still needs 2 pcs size D batteries,total 3V.

User questions & answers

Question: Can this be used with a recirculation system? IE> Have a constant flow of water through the unit at or near set temperature
Answer: I don't see why it wouldn't. It starts heating water when water flows and turns off when water is shut off. You might go thru alot of propane.
Question: What does the temperature heat up to and for how long? Does The water temperature heat up based upon the actual temperature of the water coming out t
Answer: We have ours set on 115, and it will hold that as long as there is water and gas
Question: what is BTU rating, is there and altitude restriction on this unit
Answer: 35,000 btus and there was no altitude restrictions on the info that came with the unit.
Question: Does this model have freeze protection for use in colder climates
Answer: Michele, yes, you DO need freeze protection! Without this feature, there is always water in the heat exchanger, and the low volume of water to high surface contact means this heater is more suceptable to damage than a tanked version which has a "cushion" of water to survive mild frosting, not deep freezes. Ronald, thanks! That makes me feel better, as we snow camp in the mountains at times where it warms up to 24 degrees by noon. 👍

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.

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.

User questions & answers

Question: Can you mount this on the floor on its back
Answer: Thanks for your consultation, there is no vent for this unit, we suggest you to use it outside of the camper. Any problem please feel free to contact us. Thank you.
Question: Can this be installed inside the trailer close to a roof vent
Answer: The manufacturer's instructions say it is only to be used outside, and that it is not designed for a permanent installation. Having said that, mine is installed inside an RV under a window. We crack the window when we want hot water and I am fairly confident we are not putting ourselves in danger of carbon monoxide poisoning. We run it for short periods - a little hot water for washing dishes or short showers. If the intended uses involved running it for longer periods I would want to place a proper vent over it that went outside. In any case, be sure you are mounting it with suitable clearances from anything flammable above and to the sides.
Question: Is there a vent for this unit? I want to use it inside my camper
Answer: yes,, i believe it's a round disk type battery
Question: It say that its no need to vent it so can this be used indoors without any problems
Answer: It uses a CR2032. The case takes some work to get apart to replace the battery. You have to be careful not to break the tabs that hold top and bottom together. Once you have it open, the electronics will fall out if you're not careful. You can see instructions here: http://mopeka.com/homepage/instructions/
