Will 32 gallons of propane last 2 weeks in this weather?

Depends on how cold it is. There is a lot more gas in there than you would think, as it expands over 60% from the amount of liquid. Although we use an electric heater whenever we can, we have gone for over a week in every cold weather( below freezing every night) with plenty left over. Worst case is that you would have to disconnect and go somewhere to refill.
