The insulation properties are so good that while the inside of the tube may be 150 o C / 304 o F, the outer tube remains within a few degrees of the ambient air temperature. This means that evacuated tube water heaters can perform well even in cold weather, when flat plate collectors perform poorly in these conditions due to heat loss.
