Any and all opinions on tankless water heaters

The big advantage of a tankless touted in all of their add's is "unlimited hot water (on demand)". Thats is fine in the S&B but unless you have full hookups where is all the fresh water going to come from and where will all that grey water go? I'm not sure how well they work but I know my simple 6 gallon LP/AC works just fine every time, we can both take a nice shower without running out of hot water. :R

tankless WH this is what My cousin has in the garage down at the lake its 220 or 110 it works well on both they have a garden hose hook up so that 100' of hose heats up during the day and the heater its hot I consided one but the cost would buy alot of propane, I do like to take long showers though so I put a bypass on my water heater and run 100' of black garden hose on the roof and I can take a 20-30 minute shower without running out of hot water. that is on our camper that sits at the lake our 5th wheel has a 10 gal heater and I may some day put the bosch on to pre heat my water.

Here is a post I made recently. I have no idea if this would work for you or not.

Propane or electric powered?

We have an old propane powered one on the boat but I don't trust it and it is difficult to get the temp dialed in right.

I haven't tried the electric but I have heard they have much more limited heating capability.

The #1 killer of tankless units is hard water. Minerals build up and clog the orifices so a water softener is an absolute must.

Personally I do not like the tankless. We camp a lot in National parks without hookups. I have a hard time getting the water the temperature I like. It has to have the induced draft blower running to work which takes battery power. I also think I waste a lot of water waiting for the shower to get warm, also bad when camping without hookups.

That said, mine is an earlier version and does not have the better temperature control I believe the new ones have. I will be changing mine out this fall or early spring with a 6 gallon gas/electric standard type heater. I am still looking for ways to conserve water because with either, it is a pretty long trip from the heater to the shower.
