Until it catches fire and burns your house down.
Seriously, they are all different, but usually feature some kind of safety cut-off.
Only the manual for the heater will give you an accurate answer, but I would guess you could leave it plugged in indefinitely provided it is equipped with a thermostat and overheat safety cut-off.

No , it is just a heating element similar to an electric kettle ( as long as it is plugged in and the power is flowing the block heater is still " on " ) You can use a timer or some other method to cut down on your electrical use if you like , as far as I know a well maintained vehicle doesn't gain anything after the block heater is plugged in for 3 or 4 hours , although you can leave it plugged in longer if you want

Locate the block heater. Drain out the coolant from the rad and from the block if there is a drain there. There should be a screw in the center of the block heater. Unscrew it to loosen the block heater internal clamp. Use a pair of pliers and wiggle it free. As long as it is not plugged in, there should be no worry of damage. It is sealed with an o-ring.The element will have to be worked out as it goes into the block along the side.

Can the block heater do harm if left plugged in too long?
No, the block heater will only heat as much as the resistance of the element is designed to. There is no harm leaving it plugged in. You should, however, always unplug it before starting a vehicle because the movement of the coolant across the hot element can eventually wash it out and create a break in the circuit which will require replacement of the heater element. Most OEM block heaters also have a thermostat built into the cord itself to make sure it does not overheat. I would not plug in at temperatures above freezing.
Can you use a none dedicated outlet for a space heater for a short period of time?
Yes, a space heater can be plugged into any outlet. Depending on what else is drawing current on the circuit will govern whether the circuit will trip or not. If the heater is plugged in and the circuit does not trip it can be left plugged as long as it is needed. If the heater trips after a few seconds, then try another outlet.
