I'm in the process of planning a large deck with 3 season gazebo. We thought it would be great to put the spa in the gazebo for a couple of reasons.
1. Nasty problem with biting flies and mosquitos in the summer. Flies during the day, mosquitos at night.
2. Often experience high winds in winter. -50+ windchills.
However, I'm concerned about condensation issues in the gazebo when the spa is in use. I realize that it won't be a problem when it's convered. The condensation could/would cause problems with the knotty pine interior finish. I'm sure I could use power ventilation. The questions I have are:
1. With outside temps as low as -30 F, does the moisture of a spa that's in use cause condensation problems to the extent that ventilation is necessary? Anyone have an installation like this, in winter conditions similar to mine?
2. If ventilation is required, what are you using and is it sufficient?
