Along these lines, the PBS television show "This Old House" recently
demonstrated a tankless gas water heater.  Water is heated only as used
by this gizmo -- apparently the incoming water goes thru enough length
of coiled tubing to pick up all the kilocalories it needs to become hot.
On the show, the heater kicked in as soon as the homeowner turned on
the hot water faucet, and shut off as soon as he shut it off.
This avoids wasting energy on maintaining the thermal mass of a 40 gal
water heater.  I'd like to investigate these further, as my water heater
is getting old.
