I did the same in the massive monolith we lived in in Indiana. The farthest upstairs bathroom was nearly 80 linear feet away measuring the pipe. Just plumbed in a line parallel to the manifold that ran across the basement ceiling with a “T” and down to a “T” I installed behind the drain valve of the water heater. It thermal cycled hot water through about 40 of the 80 foot run, so the youngest son didn’t have to run 20 gallons of water until he got hot water… crude but effective.
