Depending on your location the wasted water from letting the faucet run can be much more valuable than the energy needed to maintain a circ system, however install cost is high and the lines need to be entirely insulated so really, new construction works best. I wanted it on my house but I think it'd just drive costs way up, especially with a tankless as it'd be firing all the damn time.
