Reply to comment by Diligent_Nature in Recirculating pump for tankless water heater by GeekX2

Good points. The selling point on tankless for us was the unlimited supply of hot water more than the idea of not reheating water we weren't using.

I see your point about wasting hot water when we want cold. It's kind of the opposite of what we have now--wasting cold to get hot. Maybe that's a vote for dedicated loop if I decide to recirculate.

Thanks.

If you want to get some of the benefits of the recirculation system, put the pump on a switch (or even better, a timer switch) near the point of use. Flip it on a minute before you use the water, then turn it off and enjoy your hot water. You're not wasting water or energy then.

A limited hot water supply is not a bad thing. It encourages conservation.
