Summary: Anybody know about flash water heaters?



Most water heaters have a tank inside them which holds as much water
as you are likely to use at one time (say 40 gal.), and a small heater
to let it heat a new batch of water after you have used up the old
one.  I have heard that there are a few that work differently - they
have a small heat exchanger, and a big burner that lets them heat the
water as you use it.  There was an article in February 1982 Pop
Mechanics. 

Does anyone have any experience with a flash water heater?  I like the
idea for two reasons:  

1> It's usually the tank that died when a water heater has to be
thrown out.

2> Heat escapes out the side of the tank 24 hours per day.

thanks in advance
