Just FYI, this showed up in my inbox (tanklesswater@TanklessWater.com) and looks loke something that may be of interest to those of you looking for a tankless water heater.
I already got mine and won't get anything from these guys, just passing along maybe interesting info.

For water conservation, and convenience, a tank type is
best for RV use. |

Why is a tank type better for an RV with regards to water conservation and convenience? |

During a shower, you turn off the shower head to save water.
With the tank heater, the water in the line stays hot. With the
"on demand" type, the water is cold, so you have to run it
until it's at temp...
Doing dishes, etc, is the same.. run water until it's hot?
It may not seem like much, but the waste is cumulative, and
in the end, more waste water than fresh! |

Actualy my experience with the 'Seisco' brand tankless water heaters that can be located proximate to their use when there is readily available and dependable 120-240 AC service - is that they are totaly conducive to energy conservation in conventional use - they have not been without service problems - the wisdom in using this type system in a bus conversion (not PP reliant) is some what suspect when balanced against webasto, aquahot etc... systems - FWIW |

The ways to get over this hassle have been explained endlessly.
1. install a return pipe back to the FW tank , place the telephone shower head into the return line while showering .
2. On a new build install a shower / tub selector from Home Depot.
The line from the selector that would normally fill the tub goes to the FW tank.
Either of these setups will waste a tiny bit of propane heating unrequired water , rather than the water.
IF you have an engine or genset coolant heated hot water supply , the valves are avilable with an anti scalled or even pre set temp valves. $$$!

Amen, Larry.
It's safest to set the tankless thing to the lowest setting.
When I rebuilt a normal commercially made motorhome,
I researched the "on demand" types to no end. I found that
they are great for home use, under a sink, etc... but not for
the supply of all an RV's hot water.... and especially -not-
for an RV's shower.
Using a conventional gas or electric hot water heater, with an
added coil around the tank to utilize the engine's coolant to
make hot water while the engine's running, is about the best
way to go for RV applications.
Hey... do it whatever way... There's no "right" or "wrong",
just what's practical, and what's not.
From Titan Tankless Hot Water Heaters
*Will the tankless water heater work with well water/well pump?
Our units work well with well-water systems. Pressure
variations under 20 PSI are generally tolerated by the
units. Keep in mind that water flow and pressure are the
eyes and ears of ALL tankless units. This is what tells the
unit how much power is required to heat your water.
Our units are designed to operate within a range of 5-150 PSI.
It is recommended that your pump be set to run at 60- 80 PSI.
If your system's pressure fluctuates too much, there are a
few things you can do to help stabilize the pressure output.
The pressure gauge on your pump should not allow the water
pressure to vary more 20 PSI, if so, this may impair the
operation of the tankless water heater.
Intalling a backflow preventer, if you don't already have
one, is considered a must.
Sometimes, conventional and commercially proven ways, are better. |
