I am a 74 year old great grandma living in an RV. My utilities are included in my lot rent soooooo I wanted to run my hot water tank on electricity and not propane. Especially with the gas prices what they are. Thank you so much for your video showing me EXACTLY how to change my hot water tank to electric. God Bless!
Oh my goodness. This makes me so happy that I have helped. I have to say that you must be pretty good at troubleshooting and figuring things out. From your comment, it seems that you are quite handy. Glad I could help. God bless you also.
Quick question…since you live in your Rv, do you simply have the switch to your water heater on at all times or only a couple hours before you anticipate using hot water? We will be using our RV for living in purposes and not sure about the water heater use. Any help would be appreciated since you are living in Rv and probably face the same hot water needs.
@@erictorres7743 I live in a highly modified RV and I do mean highly modified (Forest River wouldn't even recognize the interior of this thing). I turn my propane only heater ON only when I need it. It has a switch for the 12vdc that powers the spark igniter. I leave it on for my 6 gallon tank for about 8 minutes in the summer here in FL and 10 minutes in the winter to take a "sponge" shower. yeah turn water on to suds up.. turn off... wash.. turn back on to rinse because 6 gallons ain't much water. Why heat the water if you ain't using it that's just plain stupid.
I love that you took the time to create a video to answers some questions for people. This will help a lot. Thanks for sharing!
Its all about heling the community......This channel would not be anything without the viewers. Thanks for the feedback:)
Actually I was not at my RV at the time, my wife had a weekend getaway at our RV and I was guiding her based on response and video. She told me that she had plenty of hot water and actually heard the water heater turning on using the propane as well so it sounded it was not on by pass. Thank you so much. But when I do get back to my trailer I will make it a point to look for that by pass so I would know where it’s at. Again, thank you for the help, much appreciated.
I am glad to help.
Great video! Although, I am still a tad confused. When I turn on the switch outside, do I also turn on the water heater switch inside? I always hook up to electric, and try not to use much propane. I have never used the water tank only though the hose. I want to make sure I don't burn out any elements. Thanks for your help!
The switches inside and outside are indepent from each other. you can turn one or the other on or both at the same time. The one on the outside for my RV operates the shore power heating element which is like what most have in their house. Hope this helps.
I don't have a switch on the outside only on the inside panel
Some manufacturers make them differently. Hope the rest of the video helped.
Great video explaining how the "hot" water heater works.
LOL. "hot". I get that all the time.

This is good information thank you for sharing and I learn a lot from your videos so thank you so much 😊
You are so welcome! Thank you for the feedback.
Ah ok thank you so very much… now I have to look for the bypass line to see if it is bypassed haha.
Did it work?
Great videos on the hot water heater.
I am glad that it was helpful.
Do you have the part number for the mother board on top of the tank and the heating element?
Hi and thank you for sharing this video. I'm new to the camping world and forgot to shutdown my water heater after breaking-down and leaving the campsite. Upon arriving home I noticed the power on and off switch was left on. Now on the control panel, a fault light is illuminated and the water heater will not come on now. How much damage did I cause by forgetting to turn it off? Thank you.
Usually, the heating element is what would need to be replaced. You can find one on amazon by putting in your water heater make and model. If you have the know how and are familiar with the electrical hazards involved, its not a hard to do replacement. However, I do recommend that you consult a technician for the repairs. For your safety of course.
@@HowToRVThank you Sir for your feedback. Today I connected my trailer to a water and electrical power source at home, and noticed the water heater did provide hot water. So far things are looking okay. However, I attempted to heat the water by using propane and immediately received a fault at the control panel. I was trying to troubleshoot and fix the problem without surrendering my camper for expensive yet simple repairs. Again, thank you so much for your feedback.
@@DonJen2478 try the reset buttons at the water heater. They look like a sheet of rubber but there are buttons resets behind them. Also, and I am sure you have looked, but if the propane is off, or empty, that will give an error too.
@@HowToRV. Thanks Mr. Jason. I did locate and actuated the reset button but it didn't get rid of that dang fault error on the control panel. I've also checked the propane level and it's okay. If I disconnect the electrical power source and use the propane to heat the water, should I also turn-off the power switch on the water heater? P.S. I have the Alpha Wolf, 26DBH-L....
what's the WATTAGE on that VAC heating element? I believe its 14kw but would kinda be nice to know for sure because I need to get one of these heaters for a special application (not related to RVing). Yeah it costs 14 cents per KW here where I live and I'm try to cut those KW's and these on-demand heaters are killing me with their huge coils. So I'm thinking I can leave this guy on for say 10 minutes what would THAT cost me? well 0.2*10*0.14 = what? 28 cents. helluva lot less than what I'm paying now!
So, if you turn the switch to off you can run the heater on propane ONLY, correct? That is, no drain on my battery (except igniter) while boondocking. Yes???
That is correct, that is what we do.
I have the exact WH you demonstrated on. I would like the WH to run on gas even when I'm hooked up to shore power . I'm confused about the off and on switch. Sorry I'm slow.
The on/off switch on the outside is for the electrical. If you want electrical only, leave the switch inside off. Be careful and dont forget to turn of the switch on the outside when you do not have water hooked up or runing. I have heard a lot of folks who forgot and burned up the eelectrical heating element. Hope this helps clarify a little more.
@@HowToRV Yes indeed. Thank you
Hoping you can help me. My gas hot water heater is lighting, but the water is not heating up. It is working on electric, but not on the gas. Thank you
If your model has it look somewhere on the aluminum tube leading FROM the burner TO the propane nozzle you should find a square hole in the tube, with a sleeve around it. This hole is to venturi-feed air into the propane stream. you rotate the sleeve to make the hole larger or smaller, which adjusts the burn. Lots of yellow means you need more air. The hole is also great for spiders and wasps to get in and lay eggs & such, otherwise plugging the tube. If the hole is nearly full open and your flame is still rich, check the tube for obstructions. If you do not have any adjustments then try checking and cleaning everything. You should see a blue flame under the tank. Be safe and mindful of propane and fire. They have been know to build up gas and start with someone in front of it and burnt them. If needed, consult a technician. Please let me know how you got it to work when you do.
Greetings, Informative I thank you for sharing these videos.
I’m catching up.👍🏽🧚🏽
You are so welcome
Thank you! Just what I was looking for.
Glad I could help!
Is it ok to leave the heater switch in the on position?
Which swtich are asking about? On mine, the switch forthe propane is inside of the RV and it will not hurt anything to leave that one on. On the outside at the water heater, mine is the electrical heating element and that one can not be left on if there is no water conected or the fresh water pump and tank is off. Leaving the electrical side on without water will burn up the heating element. The propane side is just a flame under the tank and will not hurt anything but is not recomended. In short, If you have water that can flow through the faucets, then you can leave any of the switches on. If you do not have water connected to flow, then leave them off. Hope this helps.
GD Transcend 321BH. There is no switch in side the outside panel. I do however have a switch on the inner control panel alongside the gas switch to heat with propane. Im not getting hot water using electrical. I have verified no breakers thrown and 50amp shore power is on. Would there be another location for an on/off switch if it’s not the one on inside coach control panel?
Does you water heater have the resets outside at the water heater?
Yes
@@fivedogsranch9288 Do you have voltage at the heating element? I ask because I have seen where someone has left the electrical side to the water heater on without any water in it and the heating element went bad. The is a heat controller as well but that is a tad harder to troubleshoot. I would recommend a tech for that. Also, I don’t know if it may help or not but there is a grand design owners group on Facebook and there just might be a transcend one as well. What is the make and model of your water heater?
@@HowToRV The RV is brand new. This is actually the first time it’s been used. When we bought it in November it was already winterized (we live in Western Colorado), so I set it up for first use yesterday. The water never got hot using elec. no problem propane. I pushed the reset before messaging you. I’ll leave it on overnight and turn off propane and see if I have hot water in am and will advise.
Good morning, thanks for the video and very quick replies to my questions. We are 100% good to go! Must’ve needed that reset and my only power switch, must be the inner control panel.
Thanks for the video. I just dewinterized my 2019 XLR Boost, but I forgot to switch the valves on the water heater. So I fired up the heater with no water. Now the water heater will not attempt to fire up. What have I screwed up ?
I have a video about checking the heating element. Start there. Thanks for watching.
Is there a second electrical hot water switch or just the one located below the propane piping?
This depends on you set up. Mine only has an electrical switch at the water heater.
Just bought a used 2015 Forest River hemisphere lite and it has the exact same water heater. I finally figured out to turn on the electric power but it doesn't seem to keep it hot constantly one day it'll be scalding the next day will be lukewarm. They said you can go ahead and turn on the gas button inside for the water heater and it should fire up but if it's already lukewarm will it get it any hotter? Apparently it's only a 6 gallon tank so I don't take long lingering hot showers like I did where I lived before. I don't think there's space to add a second tank and going underneath all of that I don't think there's even an access panel for those lines to the water tank! I've also been having trouble with the stink apparently from the kitchen gray tanks because it was plugged and wasn't flowing so the RV dealership sent two guys out and fiddled around with it and the park pumped out the blackwater tank again which seems to fill up in less than a day or two for some reason and I'm not using it just me. Go figure? We flushed out the gray tanks apparently and the black tank and I put that tank treatment in both and the gray tanks are open to drain but I'm getting that stench again. Something tells me something's leaking somewhere and these guys really don't want to fix it even though I'm still under the 30 day warranty and they scammed me for a 5-year repair warranty. I told him I didn't want that when I bought it and he said well then you're going to have to pass another $500 inspection fee which was the scam. I paid 500 bucks already and it's obvious they did not inspect the rig because I found things that did not work or we're missing.
You have to work with a place like that is the craziest thing i have ever heard although not surprised at all. For the stink, Ensure that your traps under the sinks are clean. You should not keep the gray tank empty all the time. By doing so, grease, dirty water, and such will leave (STINKY THINGS) behind. Yes, there are chemicals that you can, but if they are flushed out right away, they have not had time to do their job. For the water heater, the electrical should be hot all the time but it does struggle to keep up with consumption. You mentioned the consumption when you said shower usage, so I am sure you completely understand. Gas (Propane) heat will help, and yes will heat up the water if not at temperature. As a matter of fact, you should be able to run either system independently or together. If you are still having temperature issues, I would only have to guess that it is with the thermostat system and you should get a technician to look at it. Hope this helps and good luck.
@@HowToRV that might be the problem I've had people tell me to leave the gray water open and others say keep them closed so I will close them and allow water to stay in there. It has to be coming from those tanks and this being a used unit who knows what kind of stuff I mean even I put grease mistakenly down in the kitchen drain with hot water thinking it would flush completely out.
Does the water heater run on the electric if its not plugged in? Via battery or solar?
The electric does not work off the battery, only if you are plugged into shore power.
how do I trouble shoot the propane side of the hot water heater I have the same one. keep getting a dsi fault light
I have not ran into that issue myself but there are a few things you can check yourself. I do a lot of research online for topics and here is one that may be of use to you. www.doityourselfrv.com/rv-water-heater-troubleshooting/
Why i have boiling hot water at times then days just barly warm. Then days hot again
I just bought an Epro and cannot see where my bypass valves are. I believe they are supposed to be under the bathroom sink but there is a piece of wood blocking them. Am I looking in the correct spot?
Locate your water heater on the outside of your RV. Then look for a removable panel, drawer or other access inside behind where you located the WH. There are several configurations of valves. A general rule it to turn each one in the opposite position from where it is now.
When I have the button on to heat water with electric, it still heats with gas (flame). When I have button on for gas, it heats with gas. In other words.....Both options are heating via gas and no electric. Why would this be and how do I fix it??
Thanks
I was talking to someone theother day about this. Found out that their switch for electric is not only on the water heater but there is a switch inside for both electric and propane individually. I wonder if that is how yours is set up.
Should I drain my hot water heater before leaving a camp site?
I only drained mine during the winter months if I wasnt traveling. We travel often even during the winter so during those times, we would leacve the electrical side on to keep the tank from freezing. I am fortunate enough to have electrical hook up and a parking pad at my home.
I’ve got a question….. just purchased an evo trailer trailer and has the feature to use gas and electric to have more hot water… my question is that if I’m at a campsite with power and water and sewer do I need to fill up my water tank to use this feature? Or just having the water hose connected to use city water good enough?
As long as there is water fowing through the water heater no matter where the source is coming from, you should be good to go
Thank you for the response… I understood your response but I’m not sure if I’m asking the question correctly 😬 does water flow through the water heater if there is no water in the tank? Because, I do not fill my tank, I just have my city water hose connected.
yes. It goes through the water heater if your on city only. As long as you do not have the water heater bypassed like some do for winterizing, you will be good to go. A good test is to turn on the hot water site at your sink or shower with propane only. After propane has been heating for a while, turn on hot water, wait for a few seconds and see if water is hot.
Hey ive been at an rv park for 2 month. This morning i heard crackling sound outside and noticed the watwr heater was on as well as the switch and it was coming from that. Ive never used the hot water and im not hooked up to the water as i have a leak right now. Why would it automatically turn on like that after 2 months thats never happened. Was super hot at the valve
Some folks have panels inside that also can turn on the water heater electrical. Check to make sure that did not happen.
I have a 22 Jayflight SLX 324bds. How do I fill the water heater up?
If it is like mine, there are bypass valves on the backside that you have to make sure are turned to allow water flow through the tank.
For full time RV living, does the water heater electrical and propane switch stay in “ON” position at all times or only a few hours before anticipated use?
It really depends on the users preference. If I was full timing it, I would only use propane for showers and then turn it off. This way you can conserve on propane consumption.
@@HowToRV What if you are using electric can you leave it on full time or is it best to turn it on &off?
@@Tzom I doesnt hurt to kep it on but you would poetntially be concuming more propane.
what is the hot water switch in the inside panel for?
Mine is for propane heat.
Hi your videos are amazing. We have had our RV for 3 years. We have never had an issue with using our gas. But it stopped we asked a RV place and they said it sounds like your mother board needs to be changed. How do we know if they are telling us the truth. We have changed out the igniter but still not working. We were going to buy one off-line but we’re scared that we might not get the correct one. Hope somebody can help us on this channel.
I am sorry to hear that you are having issues. Although I have not experienced this myself (knock on wood), here is a link that will get you well on your way. togorv.com/rv-living/rv-troubleshooting-water-heater-issues/
What do you do for a trailer that doesn't have a switch on the outside?
I have seen manufacturers put the switch next to the panel where the controls inside are. On older models, it is possible that there isnt any shore power heating element and will only be propane.
How to make the hot water last longer in the shower when using the city water line and with turning on water heater pump?
some have different models of water heaters but on mine, I left the electrical side and propane side on at the same time and had enough to take 1 quick shower without turning off the water.
@@HowToRV I've tired many things but the hot water only last 7-10 minutes
@@12321404 that sounds about right if you are running it non stop. When taking showers, I turn off the water between rinses to help the hot water last longer.
What if I want to use propane only, do I turn that switch on also or leave it off?
I leave mine off if I am doing propane only. Mostly so I do not forget to turn it off when reconnecting back to shore power.
water heater won't light..... New camper 2021 Friendship Gulfstream. Been troubleshooting but no luck.
I could go into a ton of different things to try but this would make a really looong reply. Please check out this article and let me know how it goes. www.doityourselfrv.com/rv-water-heater-troubleshooting/amp/
Thanks! How much propane does the water tank use with normal use?
I have 2 thirty pound propane tanks and with the electrical element on and suring the summer months, I can last about 2 weeks before having to refill.
@@HowToRV so, it goes through 4 (FOUR) 30 pound tanks of propane per month???
@@brianhall3242 1 in two weeks. Only if I am using it a lot though.
@@HowToRV and, it would depend on how many people are using it as well
How do I fill my hot water heater back up after drain it?
It is the reverse process. I leave the propane and electric off and run the water in the sink after getting all of the valves back in the right position and the anode rod reinstalled.
Do you have any videos on how to increase water pressure?
Water pressure should not be increased beyond the limits of your RV. Now, that being said, If you are having issues with the incoming pressure, you will want to monitor that. I have often helped folks through online video/chat google chat. If you are interested in talking further, please send me an email at How2RV@gmail.com and we can arrange something. Have a blessed day.
i am wondering why the rv hot water does not seem to work i used to press the button and then hear the propane pop... it went on. it doesnt make that noise anymore. could the water pump need to be on first, i forget..
There needs to be water available but does not keep the propane from coming on that I am aware of. I have seen this when there is low propane in a tank or malfunctioning controller. May need to get a mobile tech to look at it.
Quick question - We own a 2020 Forest River Cardinal Lux 3700FLX - Why doesn't my hot water get hot? It is just luke warm:/
If you are getting only warm water using either electric or LP then it sounds like your problem might be with the outside shower. Be sure that the hot and cold faucets on the outside shower are both turned off. This causes the water to mix even though shower head is turned off. Also check to make sure that the water heater bypass valve is not open. Mine is located on the back of the water heater.
@@HowToRV Thank you so much!!!
Inside my trailer on the opposite side of all the controls, on the outside, there is a small box with a dial and temp numbers on it. There is a slothead screw in the middle of it I'm guessing is for the temp adjustment. I have the outside temp dial turned all the way up but the water is hot at 1st then is just warm. Not ok for a shower. So is that dial ok to adjust to a hotter temp ok?
I do not have or seen that kind of design. I would think that it is worth the try though. I would have to recommend to check the owners manual (either the one that came with the unit or online) before trying though.
Why is there a bypass clear hose attached to the cold and hot water hoses ??? Can someone explain ?
The hose that connects both the inlet about outlet of the water heater is there so when you bypass the water heater, the water can still flow to your faucets. This is mostly used to allow for winterizing fluid to get through.
If switch is on and I run out of propane why doesn’t the electric side still make hot water?
I’m hooked to power and switch is on and I ran out of propane and I got a E1 error code and lost hot water.
I replaced propane tank and I now have hot water
Please come back to the channel and see the latest video that I made on checking the water heater element.
My hot water line underneath my shower in my wolfpup is leaking can how do I shut off water to it and could still leave my cold water on ?
Try seeing if there is an inlet valve behind the water heater. If you valve that out, there will no water flowing to the hot side. Make sure that the bypass valve is not open and that the water heater is turned off electrically as well as propane.
How long is it OK to leave your electric water heater on if you’re plugged in
You can have it on as long as you want as long as you have water hooked up (City water or fresh water tank
I finally found my switch for electric but it’s not heating at all I waited and hr and still cold water 😭
Mine has reset button at the heater. Kinda looks like black rubber round buttons. Also, there is a circuit breaker in the panel inside my RV. Try the resets and checking the breaker. Is the power plugged into the camper one? I know it’s a silly question but I have seen someone forget to turn the power on when the camper was plugged in.
If my element goes bad will the lights on the on/off switch inside not come on?
I do not think it will. The switch is for the controls. Usually if the heating elemnt is bad, the breaker at the water heater or you electrical panel will trip. Now this is only if the heating element is grounding itself out. Other methods are to use a multimeter looking for bad ohm results. If you are not sure how to check that, I would recommend getting an electrician to technician to check for you. Hope this helps.
Should the electric switch be up or down inside the water heater? I bought used in the print is where I can't tell if it says on or off
Mine is down to be on. I always thought it to be weird but that’s how it works.
Is the a way to adjust the temperature on the water heater ours get way to hot blows the pressure valve
I do not have a way to adjust the temperature on mine and for those out there who have models like mine, I am not aware of anyone who can either.
Thank you for this. However, I took my Class C to a "repair" shop and they said the water heater is working fine (tank heats up). I still am not getting anything but lukewarm water, for about 30 seconds, from any faucet (or shower). After asking 3 others, learned I may have a "crack in the valve", which may also be the drip coming from under the RV. Do you have any experience with this issue?
I have not had that issue but I have heard of someone who said that they had a facet that was allowing the hot water to bypass or mix with the cold water which never let the hot water side heat up completely. You can also check to make sure that the valving behind the water heater (mostly used for winterizing) is valved in correctly. If absolutley have to, I would try to find out a way to hook up a hose or water line to the outlet of the water heater, connect a valve or something that would stop the water flow, and try heating up the water. Then you can turn on the valve or what ever you used to stop the flow and see if you get hot water that way. This method eliminates that RV hot water side and lets you check to see if it is just the water heater or something in the RV that needs to be identified. Its a lot of work but should get you to the resolve that you are looking for. Please send me an email at How2RV@Gmail letting me know how things turn out.
How do you adjust the temperature of the water that comes out the water heater..my waters to hot.
As far as I know, you can not change the temperature. It is pre programmed from the manufacturer. The only water heaters that are programmable for temperature that I am aware of are the tankless on demand RV water heaters.
does anyone know what the on/off switch is that's on the backside of the water heater, located inside the camper? Is that to do with gas or electric heating? I have already filled my hot water tank with water and have flipped the switch on that's located on the outside panel of the camper (the one that's sort of hidden behind the gas line), and I am aware that turns on the electric heating element. I've also switched on the switch on my black panel just inside the door (where are you can push the buttons for the slide outs in the awning, etc. ) that is for the electric heating of the water. I'm just not sure what the on off switch is that is located near the bypass lines .... it's actually behind what appears to be a vent on the backside of my kitchen cabinets.
Thats a new one for me. I am wondering if it is actually tied to the water heater or not. Email me some pictures and I can maybe help identify what it is for.
My water heater started making a whining noise when on the propane mode. When I switch it off or to electric the noise immediately stops. Can anyone help me troubleshoot this?
Could be the valve that opens to let the propane through. That is the only item that I canthing of the would make that kind of noise.
What if you don't have a switch to turn on
If you have an older model, then most likely you do have propane only.
Can the water heater be used on electric only and propane tanks left on for cooking without using propane to heat the hot water tank?
It really depends on your system but I can run either or both. With turning off the propane side, the electric still heats up the water but slower
Yes that small electric switch stays on for me. me use the hot water heater breaker in the powerbox inside to turn on electric and the red light wall switch for gas. Just turn it on in the breaker box when ready to use electric. Just don't forget to turn it off it's easier to forget to turn off the electric hot water heater because unlike the gas it doesn't have a light up button on the wall.
Turning on gas and electric at the same time is a powerful boost that will let a couple take a full shower one right after the other with no wait time or loss of heat. What I'm trying to figure out is why does my tank look plastic is it and if it is does that mean it doesn't even have an anode rod? If it didn't even need an anode rod to maintain the electrical it's probably the best hot water heater out there. I hope I don't jinx myself now I wanna find out, it's the answer I've been looking for. Mine looks plastic wrapped in foam like the one on the video but I have a rear kitchen model.
Mine doesnt have that switch outside
If you do not have it outside and do not have one on the control panel inside either, you may not have an electrical heating element. Another way to check is to look at the back of the water heater and see if there is a electric cable plugged into an outlet like you would see at home or a electical cable that is not 12v. It would be much bigger in size.
My water is not very hot it is like lukewarm what is wrong with it
There are so many different reasons that it would only heat up a little. I would start by having someone check the temperature controller. That is your cheapest route.
What happens if my trailer has no switch
then you most likely do not have a heating elemenet. This is typically on older models. Sometimes the electrical switch is at the control panel inside of the RV. This setup is what mine looks like
