Hello all,

My kitchen sink and dishwasher are located about 35 pipe feet from the water heater, so it takes probably 45 seconds to deliver hot water at the tap and dishwasher. To reduce the lag time, I am considering installing, under the sink, either (1) a small tankless booster heater or (2) an on-demand recirculation system such as D'Mand.

Can anyone tell me the pros and cons of these options?

Thanks.
