Have a HydroHot and have always been careful not to put the sewer line near the exhaust. I generally use a sidewinder to keep the pipe elevated. I also like to keep all lines along the coach and run them all out to the hookups at once. This means sometimes running the lines back under the HH exhaust.

Well the DW was getting into the basement and inadvertantly shifted the sewer line near the exhaust. I went out to do a black water drain and the pipe was melted in half. The gray water had been leaking onto the ground the past day or so.

It scared me to think about the possibility of a fire especially since we use the HH at night to heat the coach.

Good thing about Disney Fort Wilderness is that the crushed shell/sand material they use is quite porous and the leak, 'er wide open tube, did not cause a mess. I don't think anyone noticed. So some embarrassment saved.

Anyway, from now on, when the sewer connection is forward of the wetbay, I will run the line out away from the rig first then over to the connection.

I had mentioned this on another leg of this forum, but I have a friend who takes an aluminum basting pan and puts stones the size of potatoes in it. The heat hits the stones and dissipates without burning anything under the thin aluminum.

Good tip cwg. I decided to add some bling to my AH exhaust in the form of a chromed pipe. The new tip had a turn-down and I directed the exhaust flow slightly downward. Toasted grass! I subsequently removed the bling. I see why the factory directs the exhaust gas horizontally now.

I don't have a HydroHot ststem, but I've heard they're a nice option.

We were camped next to a rig several months back and we constantly smelled diesel fumes. We could'nt use our Fantastic Fan, because it would draw the exhaust inside. I discovered later that the folks next to us had a HydroHot system. Why someone would use it in a campground with full hookup's escapes me, but to each his own. It did leave me with a question though, do all of these systems expell alot of fumes?

Craig P., mine produces more fumes than the generator for sure. If it's really cold, the electric element in the water system cannot heat the entire coach and the diesel will kick on if we allow it. I'll use small heaters inside to keep the chill off. Only time we allow the AquaHot to operate if there are other campers nearby is to keep the temps tolerable inside (55-58 degrees). I will turn it off and wear lots of clothes to keep from smokin' out my neighbor.

RonNBama,

Interesting...I didn't realize that the system also provides interior heating. You learn something new every day.

Is it economical? I was just thinking about the current price of diesel.

The system will supposedly use about .75 to 1.0 gal per hour of run time. Not nearly as economical as having heat supplied from the campsite electrical source.

It's a nice system in that it keeps the bays heated and the engine warm. When the engine is running, heat from the engine is used to warm the system.

I love my HH system. Unlimited hot water and a nice even heat through the coach. Also does a great job in the wet bay.

Actually the system isn't quite that thirsty. The most it can use is .5 gallons an hour of runtime. Even in cold weather, which I camp in a lot, the system is only going to run 15 minutes or so an hour. Again, that is in sub-40 degree temps.

In warm weather, the ONLY time it runs is when you are using hot water. It will kick on once in a while to keep the fluid hot so there is immediate hot water. I camp for three weeks at a time in Florida. The fuel tank needle doesn't even move.

Also, there is an electric element that can be turned on either w/the burner or without. While this doesn't heat as well as the burner, it works great in conditions when you might use a heat pump.

To really conserve fuel turn off the burner while away or at night and let the electric element keep the fluid warm. In the morning, turn on before your second shower.

As mentioned, you can turn off the burner while driving as the engine assist feature is used to heat the water and the coach if needed.

From my experience, the HH is substantially more cost effective than using propane to heat the coach. The incremental cost of using your diesel fuel to heat the water vs. campground electric is very low plus you get unlimited hot water.

Finally, properly maintaining the unit by cleaning the burner, changing the fuel nozzle and checking the fluid level make it operate more efficiently.

No I do not work for HydroHot. I just can't see a downside to it besides price at purchase time and the fumes. My understanding is that AquaHot doesn't have the fumes of the HH.

Oh, one other downside is that if you are dumb enough like me to leave a sewer hose in front of the exhaust, you will have to buy more sewer hoses.

You will be the envy of your neighbors with bran-new hoses all the time.

I must have had the generator consumption rate in mind when I typed that. Duuuhhh. Thanks for the correction.

Scott,

My goodness-- what would the owner of a campground do if he knew your "tank" was leaking on to his ground? I say this in jest, as accidents and inicidents happen to all of us, at times. Go on and tell 'em what you do for a living Scott -------

The embarrassment factor I thought would just be assumed by our esteemed forum readers. The fact that I own a campground only makes it more so.

I do think I am more understanding w/customers given that I have made every mistake in RVing myself I believe.

Thank goodness it was only grey water, and really thank goodness I noticed it before opening the black tank valve.
