electric tankless water heater

whats your thoughts and pros and cons on putting a tankless electric water heater in rv.

A Tankless ELEC that really makes hot water uses MANY kilowatts and needs TWO dedicated 220volt supply lines. Tiny 110 volt boosters give about a gallons worth!  tankless propane units are GREAT but pricey!

Here is a reference point. I have a 10 gal tank one now but would put one of these in next time I need one.

I installed a 2 1/2 gallon 15 amp electric hot water heater from Loew's.  I believe that it was made by Trojan.  I have it set on the lowest setting and leave it unplugged until 15-20 minutes before I want hot water.  It works well for me!

 I have to agree that an electric tankless is not a good way to go in an RV, especially of the vintage variety.  When we got our rig, the traditional water heater had been left to freeze and crack and needed to be replaced.  We have a propane tankless in our home and love it so decided to go with the same for the rig.  We purchased an Eccotemp L5 portable propane unit. I think they are running about $125 at the moment and are available all over the internet.  My husband modified it, removing the shower head and replacing it with a quick-connect into our water system.  He did the same with the propane lines.  This is an OUTDOOR ONLY unit and not for indoor use so we hang it on the side of the rig or if there is another convenient spot in range we use that.  It sparks off 4 D batteries and provides plenty of hot water.  When we are ready to head on down the road, we disconnect/drain, coil the hoses and stash it in its little spot which happens to be the place the old traditional water heater was.  The best part about this unit is its portability.  If you need hot water anywhere, anytime you can attach it to a BBQ cylinder and go.  We are very happy with ours.  It is also nice to have an endless supply of the hot stuff rather than worrying about waiting for your 6 or 10 gal. tank to reheat.

I have used a 120 volt AC 1500 watt electric hot water in my 1970 Winnebago for many years.It was made by ISE and has a 4 gallon copper tank.This type of heater is known as a point of use hot water heater.It gives me plenty of hot water and always works when I plug it in.Also has a drain plug.Now I wonder if you might have a problem with a tankless model if you can't get all the water out of it and the temp drops below freezing?

tankless 120 ac hardwired screwed to wall under sink,connected to sink and shower lines already present in rv so draining the system already in rv will drain tankless manifold (and heating coils)due to gravity draining to lowest point and slight pitch of heater. I think all ill have to do is run the hot lines from sink and shower to my tankless heater and then to the sink and shower.thanks for responding.
