You're thinking of a block heater. It plugs in to shore power, and energizes an element attached to the engine block (some have dual elements, and the second one will go to the oil pan) to heat the coolant in the water jacket so that it doesn't freeze. In turn, once the engine is running, this heated coolant will get circulated to the rest of the system, and begin thawing out the remaining coolant.Although a block heater doesn't actually circulate the coolant when the engine is at rest, there is a type available which is essentially an electric pump which will pump coolant through a heating element and back into the cooling system... I've only ever seen it on really specialized heavy equipment.

Most diesel engines have a block heater that heats the engine coolant so that the whole engine is warm to make it easier to start on cold mornings because a diesel uses compression heat to ignite the diesel fuel.
If the heater core is not replaced can it cause damage?
If your heater core is LEAKING engine coolant so that your engine coolant level drops too low or the engine coolant is lost completely and causes your engine to overheat then your engine can be damaged beside the mess the leaking coolant makes inside your vehicle ( you might be able to just temporarily bypass the heater core so that no engine coolant is flowing through the heater core )
Will low coolant cause a cars heater to not work?
Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.
