The idea of a block heater is not just to heat the coolant. It is by heating the coolant, to keep the block and oil warm in order make it possible to start the engine in extreme cold temps and to lessen the wear and tear on the engine during those cold weather starts. The coolant being heated enough to benefit the driver quicker than if a block heater was not used is a pleasant by-product.
By cold weather I mean overnight lows of -18C (0F) and lower which it can quite often dip to in my part of Canada.
For example recent overnight lows in Calgary have been as low as -30C (-22F) a block heater is a necessity in this part of the world.
