Tankless hot water

[Leesway]

We just picked up our 2023 Solitude 2930RL and found the concern here about freezing temps. Check your manual. The tankless model we have has an antifreeze system. Perhaps Grand Design was listening to complaints.

We have a 2022 Reflection 367 BHS and have lived in it full time while building a house. We've been through two cold winters in the mountains of northern CA and had no problems with our on demand water heater and used it in temps down to 17 with a very harsh winter this year with all of the snow. We recently started getting an E5 error code and Furrion says its probably a water flow problem due to altitude and cold. This doesn't make sense to me since we haven't moved it in over a year and had no problems until now and its much warmer than it was. I played with the flow control knob and it didn't change the problem. It will start to get hot and then beep and flash the error code. Any suggestions?

Sorry to hear about your hot water issues, a hot shower is usually a reliable pleasure. The manual says: "E5: Air pressure". One cause is "Exhaust Blockage. Remove obstruction, then restart the appliance." Could that be an issue? From your description, it sounds like the unit starts up, but then throws the error. That could be consistent with a blockage. If you haven't moved the coach, the second cause of E5 ("High winds blowing on the exhaust.") doesn't sound likely. Have you tried shutting off the controller and then restarting it? The manual suggests that as a possible way to clear any codes.



BTW, welcome to the forum.

I've tried all of those things. It started after we had some heavy wind and rain and I found a thread about the issue which suggested removing the exhaust vent hose and blowing it out. I tried that once, but I may try again and use a compressor with light air flow to dry it out. Hopefully that works.

We just purchased our 2023 xls 22MLE in March so haven't been out in it yet. Some of the chat about the tankless WH got me a little concerned, so I hooked up water and turned it on to check. So far, so good.....my hope is because of everything being in close proximity, the water heater, furnace, and practically all the plumbing lines in this model, that getting hot water to the bath faucet, shower, and kitchen faucet fairly quickly should not be an issue. The furnace is right there also, which should help in cold climate. We do have a heated water hose and have camped in lower 30's and 20's before, and plan on doing more in the future. I understand some of the frustration with some posters complaining about being sold a "four season" camper, but can't have water if temp falls to 39 or below....hope that this issue is/has been rectified.

To update my tankless water heater troubles I spent several phone calls trying to trouble shoot the issue with Lippert. They were very helpful and said it was a flow issue. I adjusted the flow knob with no luck. I adjusted the water pressure which also did not fix the problem. I found if I turned the shower on half way and let it heat up and then turned it up a little further I could get it to work most of the time, but the kitchen sink never worked right with the hot water. Finally I started the warranty process and that apparently is all you need to do because once I started to fill out the information on the form the water heater started working perfectly again. Not sure what the issue was, but it is working fine now.

I am curious how much propane the tankless water heater uses. One of things I like about our water heater is the ability to use just electricity, and save the propane. I've not heard if the tankless water heaters use a lot of propane. That would seem to be the only drawback for usage, other than if you're boondocking with limited water supply.

We have lived in ours for 15 months and have found that the water heater uses very little propane. The heater uses a ton.

Thank you for the input about the water heater.

Based on our experience the TWH uses very little propane. We have been pleased to date with it's performance. The kitchen faucet does seem to take a little longer to get hot water too but really not too bad. Keep in mind we have a first gen TWH so I am sure Furrion will be doing upgrades to improve overall operation in colder climates. This has certainly been a valid concern. Even being here in Houston we take every precaution to drain it completely.
