Here are some observations on my DIY retrofit, based upon absolutely no actual science.

"Hi Rick,

My point was that while there is cold water flow into the DHW during a shower, hot water leaving the dishwasher would only be able to transfer heat to water standing within the heat exchanger. And as the delta T between the discharge water…"
