Don’t see why this wouldn’t work all this is using the thermal inertia of 50 gallons of hot water in an insulated tank to buffer power draws. With say a 20 degree delta from max temp to min temp a significant load can be drawn or shed by commanding in real time thousands of heaters to turn on or off. A simple mixing valve at the outlet can provide constant temp water even a large tank delta T. As a note I used to live in the Austin and the muni electric boffins will install a FREE high-tech thermostat in your place…if you allow them to use the thermal inertia of your house in 15 minuet to 30 min time increments. They remote shut down thousands of AC units at peak times for 15-30 min the average house should only go up in temp a few degrees in that time.

Interesting. I am curious how the communication was established with the appliances. Was it through the power grid using standard internet protocols?
