I'd rather be lucky than good.

I am in the middle of rewiring my bus, which is a real joy, let me tell you.  While pulling out random wires, splices, dc loads wired with telephone wire, thhn not in conduit, and romex not in sleeving or conduit or anything, all hooked to two 20 amp breakers, I found a .5 gal tiny hot water dispenser thing installed under the sink, with its own spigot.  It works.  It seems like a good idea and I'm going to keep it.  Would you wire this to the inverter subpanel, or the shore power/genny main panel? 

Here is a link to one similar to what i have, as I am a poor describerer.  Mine is a older and a little smaller.

Wow....instant hot water.  How about wiring it thru the inverter--if it is big enough?  I have heard they like induction/heating element type heavy-very intermintant loads.  Kinda like a mircowave?  HB of CJ (old coot)

The only problem with battery - interter - power is that the heater is going to constantly call for heat - power.  Batteries can/will be depleted without shore or generator supplement.

I have one of my 10 gal water heaters wired through the inverter.  I just turn it off when not needed.  Not a big deal to put a switch next to the sink.  Good Luck, TomC

We have an older unit (assumed less efficient than newer stuff) in our home under the kitchen sink adjacent to the den (where I spend far too much time). It kicks on about once an hour for a minute or less. It's very convenient for washing a very small number of items or getting hot cereal or cocoa going in the morning. Beats running the sink water for about a full minute to get hot water from the main tank. And the water is much hotter to boot.

The load of the linked unit (120v @ 6.5a) would translate to an inverter load of, say, 40a at 24v. Not insignificant but the duration is pretty short. It would seem to be a simple matter to provide a switch to turn it off when battery conservation is more of a concern than convenience.

Since the unit is already there and involves little to no startup cost, in my opinion, based on absolutely no experience with anything more complicated than a Class A S&S years ago, it's well worth the effort and the inverter would be a great way to power it.

Real world experience from folks who have been there and done that should be taken with a great deal more weight than what I've said. These are just thoughts from a couch potato who fancies himself as a budding busnut.

Enjoy your dream.

Personal responsibility is the the true price of freedom.
