How much heat is released when 165 degree steam turns into 100 degree hot water? I seem to need to check the enthalpy entropy table. Please help me.

The enthalpy of water vapor at 160 degrees is 2756.6kJ/kg. The enthalpy value of water vapor at 170 degrees is 2767.1kJ/kg. The enthalpy of water vapor with a difference of 165 degrees is 2761.85kJ/kg.

The enthalpy of hot water at 100 degrees is 419.1kJ/kg;

So when 1kg of water vapor becomes 1kg of hot water, it should release: 2342.75kJ.
