     I used to advocate for tankless.  I've used both, though I have  
not yet used an electric tankless.  I must say that, especially when  
combined with solar pre-heat, I'm leaning back toward tank heaters,  
for all the reasons Lawrence cites.

     I did like endless hot water.  However, I also like to trickle  
hot water into a tub, and I couldn't do that with the tankless.
