I am thinking about installing a return pipe on my hot water feed to the
kitchen to reduce the amount of cold water that is wasted before the hot
water has reached the sink.


Do you meat a re-curculting line that keeps the water in the line hot all
the time?

There will be a net lo$$ in the end. Having instant hot water is nice, but
the little bit that goes down the drain is cheaper than keeping the pipe hot
all the time.

If you are somehow using this only when the water is turned on, there may be
some saving.
