Just About Sailing December 2019 - Chinese Diesel Heater, Any good for condensation? Pt 2 Practice

This is a direct follow-on from the previous video which covered the theory behind why and when we get condensation.
In this one I do do two experiments in the boat; One with the heater air being re-circulated in the cabin, another with the air being taken from outside the boat.
The theory is clear as to which should be more effective at reducing the possibility of condensation. But does the theory stand up to a practical test? Only one way to find out.
