Lencho - like so many things here at the ranch - we make it up as we go along. In retrospect, an engine-driven welder would have made a lot of sense
(and its something we will probably get as we start the planned development).
Right now, its cheaper just to leave the 3-phase where it is and keep usage to a minimum!
Not for the first time, I wish I had been a builder/mechanic rather than a computer salesman!

The Bosch Aquastar with battery ignition I had in San Juan Capistrano on HARD well water. was a POS.
At low flow volume it would not ignite.
If you had more than one faucet running neither one would get very hot water.
The 2 D batteries worked ok for the first year, then I had to replace at 6 months, then 2 months then every month! Even though a volt meter said they
were putting out 1.1 or more volts each. I eventually hard wired a 3 volt plug in AC/DC converter to the thing, ind of defeating the whole energy
saving aspect.....
The reason for a longer flue vent is more efficient burning. In a fire place, the taller the chimney, the better the draw of O2 from the room; I
think the sane is true for gas water heaters.
Truth generally lies in the coordination of antagonistic opinions

My Bosc was bought in US for $1100 + another 200 for stainless steel flue pipe. It has electronic ignition using 110 + transformer. I hear the battery
powered ignition units they sell in MX eat batteries. Also, based on photo you really need to extend flue pipe. Bosc says min length is 4 foot and cap
needs to be 1 foot higher than anything within 10 foot around it.

In my previous post I referred to my 2 40 gallon conventional propane waterheaters. Have been going since 1991 without ever any problem, and still
going strong. At $ 189.00 each, it will take a lot of convincing to go to your Bosch on demand unit at the cost you state.

Still much too early to tell if going with the tankless heater was a good move or not, but I'm sure I wouldn't have done it if the cost had been
anywhere near U$1100. As it was, the cost of a replacement 15 gal electric heater was within U$30 of the demand heater. Won't be hard to switch back
to a conventional water heater again if we need to. So far, zero problems with the pilotless Bosch (knock on cinder block.)
Very little noticeable change in temperature when one of the other faucets is used or a toilet flushed. We do have a pressure system on our lines with
a range of 30 - 50 psi. I doubt the heater would operate well, if at all, on gravity feed water pressure.
I'm not convinced that I need to extend the flue. Nice blue flame when it's operating. With the big open side vents, it looks like you could run the
unit with vent cap totally sealed off. Even that paper UPS sticker is stick like new on the flue cap. I'm going to leave well enough alone for now and
go take a loooonnnngggg hot shower. (Just kidding, I've had my weekly
shower already.)
I think the world is run by C- students.
