The invention is claimed as follows: 1. A dialysis fluid heating system comprising:a dialysis fluid heater;a dialysis fluid carrying element in operable communication with the dialysis fluid heater to heat a dialysis fluid; anda logic implementer configured to control the heater using(i) a first heater input determined using a first feedforward determination at a first time from a first dialysis fluid temperature delta and a first dialysis fluid flowrate,(ii) a feedback adjustment of a second dialysis fluid temperature delta using a measured dialysis fluid outlet temperature and at least two of a proportional gain, integral gain and derivative gain; and(iii) a second heater input determined using a second feedforward determination at a second time from the second dialysis fluid temperature delta and a second dialysis fluid flowrate.
