Gas fired water heaters now offer a proportional
control which regulates the gas flow in proportion
to the hot water demand. these are economical and
can compensate for varying demand.

Since I'm faced with the strong prospect of replacing my failing water
heater I'm curious to learn what others think of the tankless variety
compared to the contemporary water heater tanks. Single homeowner not
having to deal with others showering, etc. Might be inclined to use the
shower while a clothes or dishwasher were operating though.

Although I'm leaning towards gas fired, electric could be considered as
an option if cost effective.
