The factory heaters are 400 Watts and are typically on the right side of the block; the aftermarket radiator hose versions draw more like 600 Watts. In most areas you only need a few hours to warm the block so a timer is a good idea. It would be nice to have a temperature-sensitive timer that would turn on later if the night turned out to be less cold than predicted.
