New dishwashers and hot water

[mattl]

Just as an update, as I've been using the dishwasher more getting ready for the holidays I find the unit heats the water most of the time.  I run the tap to get hot water initially, but with the long cycles if I come back 30-40 minutes later the tap water is cool to warm, yet if Open the DW it's hot.  This leads me to think as suggested earlier in the thread that cycle times could be reduced if the need to heat the water was eliminated with recirculation.

Thank you, Matt. I can also plug the pump into one of my timers to turn it on and off at various times.  On weekends, it would not be that hard to run downstairs while the tea is steeping and just turn the thing on. Nothing in my house is smart, beginning with the owner.

Using digital instant read thermometer

Temperature of "cold" water coming out of tap was 101.4F. Took leaving water run for >8mins to get cold water (83F), and even longer still to reach the nice frigid water coming from outside building.

This does vary by time of day. During peak usage times (mornings through early evening) *frigid* cold water arrives almost at once after opening tap.

I’ve got a closed loop hot water system and is 200 foot run, with a new Grundfos Alpha pump. The old Grundfos had a remote, but inevitably I forgot to shut it off. The Alpha has the same technology as the Nest products in that it eventually figures out your usage patterns and adapts. I LOVE this product. I use the normal/hi-temp scrub, and sand rinse cycle on the dishwasher, and the pump comes really close to anticipating fill times. It took 2 weeks of “learning “but it works. Glad I have a smart home, cuz I’m not smart. I travel a fair bit and it’s nice to look inside/outside the house, control the lights, temperature etc from my tablet.
