I adjust that heater valve 2X a year. In summer it is off and in winter I
open it ~1/3. The fan control is more than enough to control how much heat
in rear. Opening the valve fully does not make much more heat anyway and any
water flowing through the rear core takes away from the front and that where
it is really needed.
