Say goodbye to those unpleasant military showers, refilling your tank, and waiting for your hot water to recover. This revolutionary design replaces your outdated tank heater and gives you the luxury of taking back-to-back showers, washing dishes, or running a load of laundry all at once. Unlike traditional tank heaters that require constant energy to keep your water hot, this tankless, propane-fueled water heater only uses energy when you turn on your faucet or shower, providing the ultimate efficiency at a campground or off-the-grid. The endless, on-demand hot water has no recovery time and is perfect if you're on the road full-time or traveling with a large group.


Water Line Freeze Protection

No more worrying about your water lines freezing and pipes bursting. The internal freeze protection allows your water heater to operate in cold weather. When the temperature of the water lines drops to approximately 35 degrees, the unit will automatically fire up and run until the temperature of the water lines reach 90 degrees. Once the lines are heated, the system will automatically shut down.

This tankless heater has been wonderful. We don't use it as often as many other RVrs would, it has fired up instantly every time we have wanted to use it (after opening water and gas lines and purging air). This was an imperfect replacement to a water tank that exploded in a 2007 Shyline Aljero 27'... for our camper it was 1/2" taller and 2" narrower than the factory tank heater, so modifications were made to accommodate and seal the tankless water heater.
This tankless water heater has been able to raise the temperature of 60°F water to well over 120°F and keep it there while showering or doing dishes. I am pleased with the product in the conditions we use it. Well worth the price, shipping was satisfactory as well (ordered in 2022, reviewing about 1 year in service).



by:

Replaced my old 9 gallon water heater. Works well has been very reliable. No problems. But highly recommend.



by:

Great water heater but, if you plan on conserving water at all, this is not for you. Every time you turn off the hot water, you have to wait a few seconds after you turn it back on to get hot water again. One of the downfalls of on demand heaters. We took this unit out and replaced with a 10 gallon tanked heater. I will use the Fogatti for an outdoor shower in the future.



by:

Not the correct replacement for my unit even after speaking with a Customer Rep to find what is supposed to be the correct part number.

That is frustrating! I am glad to see that you are already in touch with out customer service team. Before buying you will always want to confirm dimensions, but nowadays, unless you have a twenty twenty one and newer RV, you will need to assume some modifications will be necessary because the newer campers are coming with smaller and smaller water heaters. The dimensions of this one are as follows. Overall dimensions: fourteen and three eights inches long x fifteen inches wide x fifteen inches tall Cut out dimensions: thirteen inches wide x thirteen tall x seventeen and three fourths inches deep Access door: fourteen and fifteen sixteenths inches tall x fourteen and fifteen sixteenths inches wide.



by:

As described. It is installed in a small cabin, replacing a failed heater. Nice display to tell you the status of the unit. Heated very quickly. So far I am a Satisfied customer.



by:

You are amazing i ordered it at 4:30 friday got it saturday



by:

Great swift service. I will definitely recommend to my friends.



by:

This on demand water heater is the real deal. It works great and is much more quiet than the old fashioned kind. It has a low turbine kind of noise only when it is working. You can adjust the temperature also which is a big plus. The fact that etrailer included a step by step video of instalation instructions was extremely helpful. One tip, don't forget to turn the power switch to the on position on you main controller panel for the water heater power. Overall I am 100% satisfied with this product.



by:

For a first time do it yourself or on any of these water heaters in an RV I found out it was pretty easy to do. The new one slipped right in with a few adjustments of the waterlines and some shark bites that I put the water fittings together. works fantastic I love the constant hot water for my long hot showers. The opening matched to a T. Easy DC connections, as well as the remote. Didn’t have to cut any holes for wires to fit. It was so easy. I wish I knew about the black door before I ordered it. It’ll be fine, I’m happy. I love the name”FOGATTI”…



by:

The ability to have an endless & constant supply of hot water is a must while camping. Our biggest test will come later this summer when we boondock with a 275G water tank for a week. I'm looking forward to enjoying this product for years to come.



by:

We do a lot of dry camping and am hopeing this gives us a bit of gas savings. Looking forward to using it soon.

See what our Experts say about this Fogatti RV Water Heaters

  • Troubleshooting A New Fogatti Tankless Water Heater
    Since you already checked the voltage and and water pressure on your Fogatti Tankless Water Heater # LSB64FR I recommend checking the gas pressure. The gas pressure range for the normal operation of the water heater is that the maximum inlet pressure cannot exceed 3.3 kPa (13'' w.c.) and the minimum pressure cannot be lower than 1.99 kPa (8'' w.c.). Out of range will not work normally. Also, you'll want to ensure that you removed the gas inlet cap before hooking up the gas as that could...

  • Troubleshooting An E5 Error Code On A Fogatti Tankless Water Heater
    The E5 code on your Fogatti RV Tankless Water Heater - Gas - Automatic Pilot - 41,800 Btu - White Item # LSB64FR means you're having a fan failure/no fan signal detected during start-up or water heater operation. You'll first want to ensure you're receiving 12v power to the unit. You may have something else kicking on and dropping the voltage to your unit causing this error to only pop up randomly. You may need to switch to 14 gauge wire to ensure you're not getting a voltage drop off before...

  • Troubleshooting Poor Heating On A Fogatti Tankless Water Heater
    To start I would have a licensed technician check the LP pressure running to your Fogatti RV Tankless Water Heater - Gas - Automatic Pilot - 41,800 Btu - White Item # LSB64FR. It needs to be 11" WC for the unit to properly work. If it is sufficient then you most likely have a bad thermostat or control module which would require you to reach out to the manufacturer for replacement.

  • Troubleshooting A Fogatti Tankless Water Heater That Isn't Lighting And Isn't Displaying Error Codes
    If the ignitor isn't actually lighting up on your Fogatti Tankless Water Heater then either the propane isn't at the correct pressure or the ignitor is bad. I would start by having a technician check the gas pressure to ensure you're getting 11" WC. If not your regulator will need to be adjusted or replaced. Once we know the gas pressure is correct we can start ruling out other things, such as the power, ground, and communication between the unit and controller. You'll want to ensure...

  • Troubleshooting An E1 Error On A Fogatti Tankless Water Heater
    An E1 error code with a Fogatti Tankless Water Heater # LSB64FR means you have an ignition failure. This either means that the ignitor is bad or that the unit just isn't getting 11" WC LP pressure in order to properly maintain a flame and stay lit. Since yours is newer it leads me to believe the propane is most likely the culprit. You'll need to have a licensed technician meter your trailer/motorhome's propane system to see what the actual pressure reading is and either adjust or replace...

  • Troubleshooting Fogatti Tankless Water Heater With E3 Error Code After Replacing Water Flow Sensor
    The E3 is a fail code for the thermostat on your Fogatti RV Tankless Water Heater # LSB64FR. More specifically it says the temperature control is detecting a fail. You will want to check the temperature controller connection along with the probes. You may need to flush the tankless water heater for a bit to ensure any air inside the system or particles are removed which could give the sensors a false reading. For further assistance you will want to contact Fogatti directly as they will...

  • Troubleshooting the Fogatti RV Tankless Water Heater with E1 Code
    An E1 code on the Fogatti RV Tankless Water Heater, # LSB64FR, is indicating an ignition failure or accidental flame off during ignition. If you had this professionally installed, I suggest you return to the installer for troubleshooting and repair. The most common causes are: - Lack of gas in the tank. If there is not enough pressure then the Fogatti RV Tankless Water Heater struggles to operate. This will go for water pressure too. - Faulty Igniter or faulty Igniter connections...

  • Troubleshooting No 12V Power to Fogatti RV Tankless Water Heater
    Since you have power to the wire you're connecting to the Fogatti RV Tankless Water Heater # LSB64FR, but the water heater itself doesn't have power, I recommend checking to make sure it is wired correctly. The 2 blue wires coming out the back of the unit will run to the thermostat while the red should be connected to 12V power and the black to a ground. Make sure this is how you're connecting the wires and that they are secured properly when you make the connections. Let me know if you're...

    Your Fogatti RV Tankless Water Heater - Gas - Automatic Pilot - 41,800 Btu - White # LSB64FR could not be reaching temperatures above 84 degrees for a few different reasons. The first thing to check is the water pressure and gas pressure as too low of either of these will cause the heater to malfunction.

  • Fogatti Water Heater Running Hot And Cold
    Thank you for your purchase from etrailer of the Fogatti RV Tankless Water Heater # LSB64FR. There are a number of potential issues and there isn't an offering specifically I can give you that will immediately fix the problem. It is likely you will need a certified technician, but you can check a few different things. It could be the propane supply, so you'll want to check the regulator is properly functioning first. Also ensure you are getting 12 volts at the water heater; if the voltage...

  • Troubleshooting No Hot Water Output From A Fogatti Tankless Water Heater
    If I'm understanding you correctly you're only getting hot water from the pressure relief valve of your Fogatti RV Tankless Water Heater # LSB64FR and there's no hot water at your faucet at all? If so there might be a valve between the unit and the faucet preventing hot water from flowing to it. You could also have an issue with the specific faucet's mixing valve. Try testing another faucet to see if the issue is with the entire system or just that specific faucet. If there's no valve...

  • Troubleshooting An "Fd" Error Code With A Fogatti Tankless RV Water Heater
    When the temperature of the water pipe in the water heater is lower than 43°F the controller on your # LSB64FR will display “Fd”. Your unit is going into frost protection mode to avoid getting damaged. If you're not in freezing conditions and this is happening then either the controller or the circuit board for the unit is faulty. For faulty equipment you'd need to reach out to Fogatti for warranty repair/replacement.

  • Troubleshooting An E2 Error Code On A Fogatti Tankless Water Heater
    An E2 error for a Fogatti RV Tankless Water Heater # LSB64FR indicates that you have an "Unexpected flameout failure, accidental flameout during work". This is typically caused by a lack of propane or clog somewhere in the line. You'll want to first check that your propane tank is full and that the valve is fully open. From there you would need to have a licensed technician check the regulator for the trailer for a clog and recalibrate if necessary. The last thing to check would be the...

  • Does Fogatti RV Tankless Water Heater Need to Turn Off When Not in Use

  • Why Does The Fuse On My Fogatti Tankless Water Heater Keep Blowing When I Connect It To 120V AC
    AC current is about 10 times as much voltage as DC current so the fuse on your Fogatti RV Tankless Water Heater # LSB64FR is blowing to protect the unit. You'll need to cap off the AC wiring you have and run a new line to your DC distribution panel to power the unit. This will typically be built into your trailer's power center and would require you to remove it from the wall to get the wiring into the back of it to connect it to a fused port. If you aren't comfortable working with electric...

  • Troubleshooting Error Code E-5 of Fogatti RV Tankless Water Heater
    The E-5 error code on your Fogatti RV Tankless Water Heater # LSB64FR is indicating that the exhaust fan on your water heater is not expelling the hot air. First check that there are no blockages or debris on the exhaust outlet in the cover and then look into the exhaust with the unit off to ensure that nothing got into the fan and is preventing it from operating.

  • Troubleshooting a Fogatti Tankless Water Heater That Has Power to Fuse But None to Control Box
    If you've already verified that the fuse has power, then the only other thing I can recommend is for you to trace the wires going to the unit and make sure they are not damaged. I'd also recommend checking the connection point at the thermostat using a multimeter to make sure you're getting a full 12V.

  • Troubleshooting An EC Error Code On A Fogatti Tankless Water Heater
    The EC error code mean that the Fogatti Tankless Water Heater # LSB64FR tried to start the pilot light and was unable to due to low gas pressure. You'll want to have a licensed technician check to ensure you have 11"WC at the unit. If you aren't getting 11"WC at the unit you could have an issue with your propane tanks or regulator. If this does not solve your issue please reply back and we can keep troubleshooting.
