are a solid state device which works in how the resistivity of the material increases rapidly with increasing temperature, so they are self regulating. they are designed to be mounted in a HVCA unit in front of the blower fan, in combination, or replacing, the heater core.
 
heaters come in a variety of operation voltages and controllers. dedicated ev heaters run off HV, others off 12v and home appliance ones are 120vac.
 
many European model cars have 12v ptc heaters in them.  though 12v heaters are going to not produce large amounts of heat (1kw >). dedicated HV ev heaters are 5kw+
 
=== water heaters ===
are generally work by heating up water that is flowing threw them, which is directed to the heater core inside the HVCA units. also useful for battery management in cold weather.

=== heatpumps ===
are regarded as the most efficient type of heating in a ev. Isn't a electronic heater 100% efficient? yes, but heat pumps don't use the energy for creating heater, rather they use energy to source heat form else where. they become less efficient the colder it is.
