<DIV><FONT size=2 face=Arial>Can you recommend a brand of electric tankless
heater. I am looking to be able to get 120F. I could probably make
due with less. This would not allow me to mix cold creek water during
draught conditions. Therefore, I would need to use only cistern
water. The ambient water temp is 55F. To get to 120, I need a rise
of 65F. I suppose I could slow the flow rate to get a higher
temperature. The normal flow rate is likely around 3 gpm.

<DIV><BR></DIV>Eli, this begs the question: if you are already replacing the
water heater, why not get an on-demand electric tankless system that supplies
water to the bathroom only when you want it? More compact than any tank
so you can put it somewhere convenient and it would eliminate virtually all
the unavoidable standby losses associated with a tank?
