Right now my household geo unit has a desuperheater preheating a water tank with no elements which feeds an electric water heater. Unless we are in the depths of winter the preheat tank never gets very warm and in the summer it does nothing.
Mechanic - I don't understand the above. My desuperheaters provide LOTS of hot water in the summer, but almost nothing in the winter.
