1/2". 1/4" is too small, and anything bigger is un-necessary.
How much output can the heater keep up with, anyway?
8 gallons per minute of 150 degree hot water. It will sit on the outside
wall of my bathrooms. Since it is outside - no stack is necessary. Just
water in - water out - 110 volt to run the computer and igniter. When no
water is being drawn - no fuel is being spent.
