An aftertreatment system includes a selective catalytic reduction (SCR) system, a heater, and a controller that determines a rise in temperature of exhaust gas at an outlet of the heater for a plurality of power levels, predicts a first temperature of the exhaust gas at the outlet of the heater based on the rise in temperature, predicts a second temperature of the exhaust gas at a location of the SCR system based on the first temperature, compares the second temperature for each of the plurality of power levels with a target temperature of the exhaust gas at the inlet of the SCR system, selects one of the plurality of power levels based on the comparison, and adjusts operation of the heater based on the selected one of the plurality of power levels to achieve the target temperature of the exhaust gas at the inlet of the SCR system.
