I don't think they come stock but you can certainly use an aftermarket engine block heater if you really wanted to. the two main types either use a small gas burner or a simple electric plug in type. really not needed unless below -20'F though.
I am not thinking of getting one. Although around 30 years ago I could have / should have bought the rights to import or build here the one I saw in Germany.
I have a sporadic power drain I haven't been able to fix. Something prompted me to think that maybe there is a heater somewhere and its sensor is gone mad.
Re your link, it is electric. The one I saw in Germany took the gas from the tank and heated the car completely by burning in a closed chamber. It would heat both the engine and the interior.
