I spent two decades living overseas, mostly in small apartments with
tankless hot water. Where I lived these units are considered low end, and
larger/nicer places had hot water tanks. Whether the unit in my location
was gas or electric, I was never happy with the combination of water
temperature and water flow rate, and gladly moved to a MUCH nicer apartment
as soon as my employer was willing to spend the money (e.g., "Bamboo Grove"
apartments in Hong Kong, monthly rent of $11K US$).

Both types of units have compromises, but I wouldn't consider tankless units
when I renovated our current house in the U.S.

I read the link, so the idiots utility bill went up with his family,
so what, that is not a verification of anything but overuse. What is
verificartion is the Energy Factor and Efficency Rating, verified and
published. Sears best tank the PowerMiser, has an energy factor of .63
Sears lineup goes from .58-.63 Energy Factor with an efficency of only
in the 80% range. Tankless start with an Energy Factor of .81 an go to
90+ with efficiencies from 82%-94% for the Takagi Th1. That guy is a
total idiot if he can`t figure out ratings and math.

My unit lowered my utilities from 25-30 for a electric Newer Rheem foam
insulated, with added blanket, to 6$ Ng in the summer, and that
includes dryer and all cooking. So my payback is apx 4 years. Sure tell
the kids you have an endless supply of HW and watch what happens. As to
Eveness of temp, Rinnai-Takagi have units that keeps outflow monitored.
My Bosch 117000 btu unit does not, but never varies more than 3 degrees-
hardly an issue. Bottom line they work, just don`t tell you kids the HW
is endless, or your gas bill will be endless.
