Hello rotaryeng,

  I've purchased one of Ed Klepies heater cores and was thinking about
  a water control valve for controlling the amount of water flowing to
  the core, ala automotive applications.  The thinking being that a
  water control valve will give less/more heat as needed.

  By Ed's advice, the heater core will have no air flowing through it
  if the fan is in the "off" position, therefore, if you don't want
  heat, just turn the fan off. No valve is required and no valve
  reduces complexity.

  What have some of you-all done with this question?

I made my own heater, using a heater core for a Ford Escort, and a small
muffin fan. Since my heater core is located inside the cabin, just behind my
radio stack, under the glare shield, I do not want to have 180 degree water
flowing through the core when I don't need heat. Some *will* be transferred
to the surrounding ambient. I plan on installing a ball valve to control the
flow of water.

Bill,
I'm in the same situation with the heater shutoff valve.  Take a look at the '70 Fords (Mustang).  The Mustang has a heater shutoff valve that mounts on the intake manifold and is operated by a cable.  It is lightweight and should be available from one of the classic Mustang parts suppliers, or possibly even your local NAPA or Ford dealer.
