Answering your own questions

I think you know the answers. I have a Noritz NC 111. The HX holds probably about a gallon, which seems to cool off faster than the water in my pipes. So every draw for hot water that is more than 5 minutes out from the last one involve close to 2 gallons of cold, which is a problem for washers. We all know that the only cure for that is storage, either circulated or heated as in a water heater. At this point you are not talking energy savings at all, just decadent unlimited hot water. Thats what I tell all my clients and usually end up putting in a 50 gallon, 65,000 water heater with high temperatures and a mixing valve.

Internal heating element

When facing this problem upgrading the washmachine to one with its own heating element may be better than installing a "Buffer" tank.. Bosch/AEG/Miele/ASKO/ are some of the Manufactures that offer these Machines..
