An 'easy' solution could be putting an ordinay ceramic heater underneath the car or simply blowing hot air into the engine bay.
The space heater in the cabin has a fan so it heats the interior in about 15 minutes. The tank style coolant heater takes at least an hour but 2 hours is better. The Katz heater on the oil pan puts heat into the whole engine bay in 45 minutes or so.

In my opinion it is worth the time to do a clean installation so it is convenient to use on a daily basis. Also, the engine heaters can be used if you have to park outdoors with the car locked. Google FrostHeater on TDIclub.com for install info on the tank heater. It wasn’t difficult. I ran the cord to a marine style plug. There is a photo in my albums.
