Maybe I should put on my black and white horizontal striped shirt, put on a beret and grow a pencil thin mustuche so I can be Mr. Frenchy-frenchman.
Wouldn't going the "Frenchy-frenchman" route negate the need of hot water for a shower in the first place?

 
I can get (non UL-listed) Chinese-made, propane-fired outdoor tankless heaters for $85 each out here. They are small and you need one outside each bathroom or fixture for them to work right, but a few friends who have them swear by them. (maybe I should open an eBay store selling them to you suckers.... )

I'd personally rather opt for a UL-listed appliance, and an electric one just to save the trouble of buying gas all the time. I already have a gas range that's fed with a 90lb tank, and it's such a pain to get it refilled, and it always runs out on a Friday afternoon, leaving us stuck without an oven until Monday. But then again, when our power was out twice a day for 3-4 hours at a time last year, a gas-fired water heater would have been a nice alternative....

 
I think the big advantage for a tankless heater is when you have lots of people in the same house taking showers back to back and whoever is last in line with a tank gets a cold shower.

I saw this little device somewhere that may be a cheap solution: http://www.ecodrain.ca/

 
we looked into it but the whole installer needing to be certified/licensed jumped the installation costs because there weren't any local.

 
The new house has a tankless water heater / boiler combo. Its great for when two showers are needed at the same time laundry / dishwasher is running.

Also have a propane powered unit for remote work, needs to be reset every 30 min., but is otherwise handy to have around.

 
You can get a good size, gas fired one for around $1000. I don't know if they ever pay back, because your standard electric tank is ~ $150-$200. You would have to use alot of water to make that back in less than 10 years. The real advantage is never running out of hot water. My dad has an electric. Took two 40 amp circuits. It works ok for a household of 2, but you cant use more than 2 things at once or everybody's water pressure drops. If you have a house of any significant size, you should use a gas fired heater. Just be sure to get the pipe shroud, insulate and maybe even heat trace the lines outside.

 
I've been asked several times by owners/contractors about my exterior, gas fired, tankless water heaters, "Is that thing gonna freeze?". My response everytime has been "well, I haven't had one to yet". That changed last month. I had a contractor call and say that one froze on a job we designed 2 years ago in 27F weather. I think something fishy is going on, because it faced colder temps last winter and didn't freeze, not to mention that it is supposed to be good down to 5F, BUT I can no longer just blow them off. I now specify the factory pipe shroud (wind break), insulation and heat tracing for any exposed lines.

 
Wait, are there people other than Dleg that have water heaters outside? I mean, we have a water main, but it's buried under the driveway and the only part that sticks out is the meter.

 
That sounds like a euphemism for when things go really badly. "Things have gone pretty much south of Kentucky."

Now I get why I didn't pick up what you were putting down.
