Who has a tankless hot water heater?

[nstygma]

i was going to go with one of the big electric units, but the 55 degree rise in water temp wouldn't work for me in winter. My winter incoming water temp is 50-60 degrees.

if i make any changes, i will install a recirculation system using something like these:
