You use 50 kJ heating 238 mL of water from 10 C to 60 C, then mix it with 238 mL of 10 C water to get 476 mL of 35 C water.
With a heat pump water heater, the 35C water is cheaper than the 60C water- less electricity for the same amount of energy moved

Isn't the energy the same? You use 50 kJ heating 1 L of water from 10 C to 60 C, then mix it with 1 L of 10 C water to get 2 L of 35 C water?
Unless you're using a heat pump water heater.
