Running the heater won't impact how much fuel is being used at all, heat is a waste product from running the engine. Running the AC will have some impact, maybe not much but it is an additional load on the engine.
I don't know if it would be cheaper than just idling the car, but you might look at a Little Buddy propane heater, it's safe for indoor use.

Or consider driving south where it's warmer for the winter.
