The heat comes from the engine not the "heater". With the hvac on auto the fan will not blow cold air on you as per this post.
If you prefer -30c air blowing in your face you can drive with the window down with your head out the window or manually turn the fan on high before the engine warms up.
On those cold days I prefer not to have cold drafts but the steering wheel and heated seats cranked.
