Here is maybe a better idea:
Leave your current water heater alone - that way your wife always has hot showers.
Add a second water heater in front on your water heater and this one runs off the solar dump load. It will always be cold water - and will heat the water up before going into your regular water heater.
Then you only need to program your dump load to turn on/off automatically - and you don’t forget to turn it off.
Good luck
