1. A heating system for a peritoneal dialysis apparatus comprising:
a pumping apparatus configured to pump dialysate into or out of a heater bag;
an electric heater configurable to operate at an AC line voltage in a range of about 100 to 120 volts or an AC line voltage in a range of about 200 to 240 volts;
a current sensor configured to measure an electrical current in the electric heater;
a controller configured to receive a measured current signal from the current sensor and to control a temperature of the dialysate using the electric heater; and
a heater circuit arranged to configure the electric heater to operate at the AC line voltage in the range of about 100 to 120 volts or the AC line voltage in the range of about 200 to 240 volts, based on the measured current signal.
