Not a feel good thing here. When you have three adults, 2 teenage boys
and two little girls in your household a storage tank hot water system
is just not going to cut it when everyone wants a morning shower.

The closest hot water taps to the unit get hot water within seconds,
the farthest (kitchen) in about 40 seconds. That sink has a gadget to
capture the running water until it gets hot.
