No, it's not normal for it to be "painfully hot." You might want to take a quick voltage reading on your system and make sure you're within specs (around 14v, engine running above 2000rpm) and not somewhere too high. If the voltage is normal, then you can either replace the rheostat or add an in-line high-wattage resistor to lower the resistance you dial in on the knob, and thus lower the heat.
