I read all the replies to this IMO brain-dead, overly-complex and

The easy cost-effective solution is not to move heated water but
(presuming you can) move the power source. In my case it's gas. If you
have electric it's already there. Oil? Wake up to the 21st century.

Place the water heater in close proximity to the point of use. For my
main bathroom it's in a closet underneath. For the kitchen there's
another one in the basement right below. For the second bathroom it's
on the same floor in the next room (another closet). I also have them
plumbed so that any one heater can provide hot water for the entire
house in case one or even two break down.


Before you break your arm patting yourself on the back, read the original requirements. The OP was looking to save money over a continuously running loop system. How does installing up to 6 water heaters, each with their own standby losses, save
operating cost?

And what makes anyone think that there is room, it's practical, to put
six water heaters in a typical house?
