That has to cost more than the same water put down the drain.

No...

??? just that. No defense?

Bob does have a point as far as the "turn the pump on only when hot
water is wanted". Probably pretty much a wash as to cost.

If the reciculator runs full time, then you are paying to heat by
whatever amount all the space the pipe runs through 24/7. Yes, even
if the pipes are insulated there is a loss.

except a good portion of that heat goes into the house in most cases, so
isn't a loss per se. if you live in a place that is undergoing a drought,
the savings in water could be offset by the cost of the energy.
