Any opinions among other owners in cold climes?

I plug in my Tanis heater immediately after a flight, loosen the oil filler
cap and cover the exposed filler hole with a lint-free, old cloth to catch
the humid air that escapes, and wrap the engine and prop with an insulated
cowl blanket. This is in central NY state.

The aircraft will then sit for three nights until I pull it out of the
unheated t-hanger to fly again.
