Many dishwashers have a heating element that will heat the water anyway
so you don't really gain anything by adding a water heater for the
dishwasher.

Any small point of use in-line water heater would work for the kitchen
faucet. Or maybe consider a separate electric point of use faucet. I
have one of those on my kitchen sink but don't use it much as the water
is very hot, near boiling.

cycle time will skyrocket to many hours for just a single load.

dishwashers arent designed to start with cold water.........

the multi hour cycle time will be inconvenient, wear out dishwasher
parts sooner, and run up energy costs

I had a Whirlpool gold DW that has a cycle (automatic) just for heating
the water if it was not hot enough. Many times I would save the
dishwasher to last after doing showers or laundry. The water would be
too cold to take a shower but I didn't worry about the DW, I just let
the heat cycle work as designed. The dishwasher would take noticeably
longer but not hours, maybe 20 min longer. Though my water was not ice
cold, but I believe my situation was similar to the OP. The OP said
(in his 2nd post) that the main water heater is too far away. He never
said the DW was connected to the cold line.

For the OP energy cost are a wash because he has to add a 2nd water
heater just for the kitchen so the same energy cost goes to the WH
instead of the DW.
If it were me I would get a small under-cabinet water heater for the
sink and not worry about the DW unless the DW did not have the heating
cycle.
