Cool, you don't live that far from me at all.
As far as the heater, the readings I get with my IR gun indicates that the heater itself runs around 120°F and the surrounding block will reach nearly 80°F. The instrument cluster temp gauge reads on the cold mark once the coolant reaches 140°F. Overall the heater does help you save gas and some wear and tear on the motor for cold starts. Not to mention that it will warm up faster having the block preheated.
