   Just buy water kettle with thermometer.   
      
   I use one to boil eggs   
      
   I set 90 C   
   to make temperature rise under boiling point   
   than wait 1-2 minutes   
   to make inner air gap to leave   
      
   and rise temperature to 100 C

   As I understood the question, he wanted or was told to ask for this   
   capability from a lightly or un-modified restaurant hot water urn without   
   the constant standby power drain from keeping it hot between meal times.   
   There might be an unexpected demand for hot water in between.

   Home electric water heaters approach it with the quick recovery element near   
   the top, where hotter water won't mix downward (much), which is possible   
   because they are always full.

   In your recycling scheme how does the home operator dispose of the toxic   
   waste products? Will they be in a country that doesn't care?
