I should add that my primary motive for installing a block heater is to get enough heat out of the engine that I can safely defrost the windows and get a little cabin heat on my way to work.

The little 1.4L engine in this Cruze takes FOREVER to warm up on my easy commute, and on colder days in the winter it never gets to full operating temp before I get to work. This is with the use of the factory installed 200W oil pan heater.

I'm not doing this to save money, though it will be nice to see a slight fuel economy benefit if things work out that way. Adding the pump to this system is mostly to satisfy my OCD, which rarely allows me to plan a project without trying to make it the best it can absolutely be. Cost is not the primary motivator here, though as with anything it is a factor.
