We picked up our Class C last weekend, and as expected it doesn't have hot water long enough for my wife to shower and wash her hair. We were planning to add a tankless propane heater to it (currently has 6 gallon standard one now) but I have been reading about problems with them. Some people say they don't provide consistent hot water, and to me that defeats the purpose! Has anyone converted to one comment?

Would this be in addition to the regular tank water heater? I wouldn't want to give up the propane option when unplugged. We had tankless in the house. It was quirky sometimes. Sometimes it would just suddenly stop. However, it may have been because it was aging. When it died we replaced it with a regular tank, mostly because of the huge replacement cost.

I don't know how long you have been RVing. Do you have a shower wand that you can turn the water on and off to save water and make the hot water last. With a hook up you have unlimited water which is great but you still must conserve the hot stuff with the small tanks water heaters have.

One of the great pleasures is coming home or getting to a hotel and taking a LONG LEISURELY HOT shower.

Well, my $0.02, I don't have one in my motorhome, but I did install one in our sticks & bricks. Whatever it saves in gas/electricity, it uses in water while you're waiting for the hot water to get hot enough and travel through the pipes. If you're always connected to full hookups and water conservation isn't an issue, I guess they're fine. If you're boondocking a lot and water is at a premium, I think you're better off with a tank-based system.

Just out of curiosity, does your water heater heat with gas AND electric simultaneously? If so, do you have both on when she's using them? If so, and she still doesn't have enough hot water, I would think it's time to re-evaluate her procedure. Tactfully, of course! [emoticon]

We have a 10 gallon hot water tank in our rig, but with gas & electric running, we have never run out of hot water during successive showers. It does require that you shut down the water flow while soaping up. If your shower head doesn't have a shut-off installed inline, that would be my first suggestion.

Good Luck,

I believe it is only propane, not electric and propane. I was planning on replacing with a tankless propane system as we won't always have hookups. Water conservation isn't a concern.

In addition to the tips here, I had received one that was really useful for a related problem... There's a bypass switch that needs to be off (perpendicular to the hose) and is typically located next to the water heater. It's used when flushing the system, but if you leave it open/ on then your hot water "runs out" really fast because it dilutes with the cold water going through the bypass.

Guess it's personal experience. RVing for 20 +years, never had a complaint from the wife about running out of hot water. All my RVs had (have) 6 gallon tanks. Some (older ones) gas only, newer ones gas/electric.

We just made sure there was around 10-15 minits between her shower and mine. And...take whatever as fast as possible. Now, at home, she does take (seemingly) forever, but realizes the big difference between the house and RV hot water supply/system.

We usually camp in "state park" type sites, only water and electric, so long showers would mean frequent tank dumping. So we almost always use the campground showers.

That said,

We rarely hear complaints about hot water shortages with even six-gallon heaters

We hear more complaints about tankless with inconsistent temperatures unless water is run really hard

Many tank heaters (Suburban SWxxDE series) can heat with AC power and LPG at the same time and that solves the problem for those few who have it

We had a propane one on our boat and it was a bear to keep the temp consistent. It would go from ice cold to scalding hot and back any time you made the slightest adjustment to flow.

I agree with Rick Jay. `Navy' showers should be the mode for RV's.
My Wife and I never run out of hot water either.

IMHO: Tankless water heaters in any RV are a very poor idea. Unless you have full hookups 100 per cent of the time they will not provide the heavily advertised "endless supply of hot water" {what a joke}. As noted using a Tankless system will quickly fill your gray tanks as it empties your fresh water supply {and your propane tank}.

Keep in mind most of the tankless systems do not work very well as they are extremely temperature sensitive which can vary from exciting to downright painfull with the instant temperature swings. Our 6 gallon AC/LP water heater is enough for both of us to have a decent short shower and if you can wait just a few minutes between showers you will have all the controlled hot water you need.

As always... Opinions and YMMV.
