Is there a small tankless unit available in the USA for under the sink,
for example. We live in a condo and out hot water tank is at the
opposite end of the unit from our kitchen. It seems to take forever for
the hot water to reach the kitchen sink and the dishwasher. I was
thinking of an auxiliary tankless unit for under our kitchen sink and
then we could disconnect the hot water tank from the kitchen.


You can do that, but a better install would be to install a large tankless
unit in series with the tank and recirculate the hot water with a pump.
This is according to a plumber who does a lot of tankless installations.
