So.ghe closer the the tankless is to your faucet or whatever the quicker you get hot water.
It has to push any cold water from the pipes.
The only issue I could see with the tankless is not having adequate pressure.
The ones Iíve used ďtakagisĒ require a certain amount of pressure to kick on.

My Eccotemp requires 25psi to turn on, my pump supplies at 40psi.

Nice.
What sort of pump are you using?

New around $60. I bought a new/used unit off an eBay RV supplier for $19.95

This who I bought mine from, they have many for $25

I have an Ecotemp L5 and I'm happy with it with these admonitions: Put a recirculation circuit on it so it doesn't cycle all the time; Put a thermocouple cutout switch on it at the output pipe to guarantee you don't over heat the water lines; Get help from the Mfg adjusting the fuel mixture to your particular installation. As far as I can tell all of these units will raise the water temp a set number of degrees over inlet water temp so especially if you use a recirculator the incoming water temp will continue to rise and the outlet water temp will also, hence the thermocouple. I learned that by blowing out my PVC hot water line after the water temp got above 140 degrees F. Jack

My only experience is a 13 gallon tank style water heater. Mine is for Marine use and has has an electric element along with a heat exchanger coil to pull heat off the engine. I have only used the electric element so far and have hooked the heat exchanger loop up to a diesel fired water heater that I still have to run the fuel lines for the diesel heater.

How it works so far: three people can take a shower in a row without a problem and maybe more but I didnít have a fourth person who wanted to shower. I have been using it quite a bit lately as Iím living in the bus right now and I have not run it out yet. I can do laundry, dishes, and shower all at once without a problem. You do need to be plugged in of course. A bus is small enough that it doesnít take long for the hot water to arrive at any fixture. Maybe 10-15 seconds at most. Though all my fixtures are within 10 ft of the water heater.

So far, so good! It has its limitations, but as long as that's OK, it's easy to deal with. The main thing is the temp of the water coming in. If you've got 40-50 degree water coming in. It'll only get you to about 80-90 degree coming out... In the south most of the year, no big deal. When we're in Montana. It can be challenging! Really depends on what and where you are using it. But as far as an inexpensive, reliable option, I like it.

I also have an L5, but I'm having a hard time visualizing this recirculation circuit. Does that recirculate the hot water -> faucet -> return line -> back to cold water inlet?

Yes, that is right. The hot water line passes by each hot water valve and continues on back to the water tank. A solenoid valve at the end of the return line allows water to flow continuously thereby keeping the heater turned on. I have a switch at the kitchen sink and another in the bathroom so I can direct the flow from either location. As it turns out, Even with the recirculation valve open I still have enough water flow available for dish washing and showering though at a low volume--which is OK with me. I chose to use two water pumps, one for hot water and one for cold water along with two accumulators to smooth out the overall water flow.

Why can't you mix at the output source?

I was reading on EcoTemp's website that you should not mix the hot water from the unit at the output source. Why is this?

Its because it will cause the heater to cycle on and off constantly chasing its tail trying to find a constant water temp. Two pumps, two accumulators and a recirculating hot water system will cure all that.

With a tankless it should be mounted between the kitchen and bathroom if you do a build keep your kitchen and bathroom next to each other and on the same side of the bus and it will save you lots of money

When you say accumulators, are you talking about expansion or pressure tanks?
