I'm a maroon. For the time/effort it takes to get to mine under
the sink-- and I don't bend over like I used, too-- I could have put
mine directly underneath in the basement and it would be at the foot
of the cellar stairs and out of the way. It might even be worth
re-doing one of these days.

If you're paying a plumber- maybe not. The first few I used only
lasted a couple years each. The next one went 4 yrs- and now I'm
using a new style for the past couple years.

Ohh-- *Those*- I'm with your plumber. Mine is just for a
couple cups of tea or cocoa-- or removing labels-- or any other reason
you might want 180 degree F water in an instant.

Mine keeps it hot all the time. It is small enough and well
insulated enough that it doesn't even raise the temp under the sink
and doesn't use much electricity.
