So I figured the savings were in how inefficiently cars turn gas into electricity, but I don't know what the numbers are for that. can anyone fill in on the rest of the math?

Some where on dieselplace.com I spelled it out pretty clearly.
As long as you don't leave your block heater plugged in all the time it will save you money. If you are on call or something to that effect and leave your block heater plugged in all the time it will cost more, but will save you time defrosting or warming up your car during the winter.
Being able to schedule your block heater use somewhat during winter to help deice your car it can cost you about half as much as burning fuel to warm the engine or deice it so you don't crash into things or run over people.
Then if you can avoid crashing into things or running people over just 1 time its totally worth it all.

(this isn't the post where I go into great detail about electrical cost versus buring diesel to warm the engine, but gives you an idea)
