Hot tub snorkel

This is probably not what you expected. Our bathtub has a whirlpool component that uses forced air to power the jets.
This is the small attic crawl space on the north end of the house that shares a wall with the shower in our bathroom. Prior to this energy saving overhaul, the only things stored in here were scraps of drywall and various junk from the remodeling of the bathroom, plus two large bales of cellulose insulation left over from when the attic was done.
After carefully cleaning all of that out, I stapled Reflectix insulation to the studs. Before this the open studs left the plaster and lath backing to the shower clearly visible.
Then I covered the floor with a jigsaw of scraps of foil backed foam that were on the damaged pile at the building store.
The small cylinder is the air pump for the bathtub. I knew I was going to spread the cellulose insulation on top of the foil board, so I had to protect the air intake from sucking in tons of cellulose fiber and burning up.

This snorkel is about $3 worth of PVC with a small circle of screen door screen over the tip.
PVC isn't that great for the environment, and I hesitated to use it. In the end, I chose to work with what's here and eliminate waste where I could. While not the best environmental material to use, the alternatives would have likely generated far more waste than simply adding to the PVC system that is already in place.

Here's a couple pictures of the finished product. Since the floor of this attic space is the other side of the ceiling in our kitchen, it was important to me to block as much of the heat transfer here as I could. I piled the cellulose deep and sealed the little access door with some weather stripping.






I may have imagined it, but I believe that the bathroom and the kitchen were both warmer this past winter as a result.
