I don't know that block heaters are really a necessity here, but they sure are nice if you park outside.
As for how they work, I dunno. I just plugged my truck in. The current truck doesn't have it tho, but does have heated seats so I just fire it up, go back inside, get ready, leave and take it easy on the throttle until it starts to warm up (the needle starts moving).

Sometimes I think...
'Do I really want a beer?'
Then I remember there's a supervolcano under Yellowstone that is 40,000 years overdue, and when it erupts, it could potentially cover most of North America... and I'm like,
F YEAH I WANT A BEER!
