A pulse electrothermal ice detachment apparatus includes one or more coolant tubes, and optionally, fins in thermal contact with the coolant tubes. The tubes and/or fins form a resistive heater. One or more switches may apply electrical power to the resistive heater, generating heat to detach ice from the tubes and/or the fins. A freezer unit forms a heat-storage icemaking system having a compressor and a condenser for dissipating waste heat, and coolant that circulates through the compressor, the condenser and a coolant tube. The coolant tube is in thermal contact with an evaporator plate. A tank, after the compressor and before the condenser, transfers heat from the coolant to a heating liquid. The heating liquid periodically flows through a heating tube in thermal contact with the evaporator plate, detaching ice from the evaporator plate.
