How do I keep the heat out of my high ceiling?

I can see what's below but my mother put a loft for the Grandkids and a door to keep the heat from rising. She made a cute Indian type ladder for it. We also had a stair door to keep the heat down.

How a bout a hook that you can attach a small fan too and remove as well?

The only real way to keep heat from a ceiling is through stratification which is generally achieved through radiant floor heating & no fans or furnace blowing air around

The only other option is to use the ceiling fans to redistribute the heat back down

As for a tarp across, make sure it is of a radiant material to help redirect it back down & your edges are sealed tight. You might look into how they automate pool covers & shade structures

I would close that off and turn it into a room with a door to keep the heat out of there.

I'm not sure how to do it,but I think there's a way to reverse the fans spin so it spins in opposite direction to pull heat downwards. That would be my first action!

The best way is to make sure your fan has a reverse setting to push the warm air down, if not replace it with one that has .

Lorraine & Eileen have the simplest remedies . Going on the same idea, a cold air return connected to your forced air heating system could be your most effective addition. That would be under advice from an HVAC technician, or more than one, a second opinion never hearts! If that were not possible you might even consider building in some high volume Panisonic bathroom fans (very quiet), and plumb the vent pipe to the lower levels of the room. That air is not going to come down by itself. You have some nice looking wood work from what I can tell and the grills of the fans could be made of similar wood that is used in that area making blend in less noticeably. Of course all of that plan would require an attic and wall cavities to accommodate the mechanical aspect of the installation. Just a thought outside the box!

All most all fans have a reverse on them. At 30 feet I would call an electrician, have a newer fan installed , if it is an older one and have a remote controller installed in it. If it is not very old a remote can be put in it. The draft has to go down in the winter and up in the summer. The blades of the fan will determine the volume it can handle. So it might need to be larger.

My husband and I have a house with a similar issue. Our living area consists of living room, dining area and kitchen. The kitchen is below a loft so it has a normal height ceiling but there are no walls separating any of the spaces and the rest of the area is open to the 2 story ceiling above. We have a fan that we reverse in winter and run on medium that makes a huge difference. The one thing that's different is that our fan hangs much lower. It is mounted on a section of the down slope of the ceiling and hung with an extension rod, about 6-8 ft I think. It was the longest rod we could use without the fan wobbling too much when on high.

I'm definitely no expert on this but possibly, with your ceiling fan so close to the top of the ceiling, it's not able to push the air up enough to get good circulation.

Also, if your space is very large, if your ceiling is configured in a way that it can be done, you might want to look into replacing the single fan with 2 fans spaced apart to move more air.

I understand the desire to keep the aesthetic look and try to find a functional solution. Have you considered the use of a double ceiling fan? It works much better than a single downdraft fan (unless you buy a really large one) because of the way the fans are angled. http://www.lampsplus.com/products/ceiling-fans/s_double/?cm_mmc=GOO-SE-_-fans-ceiling_(phrase)-_-type-double-_-double_ceiling_fan&sourceid=SEGND&gclid=CIrPx7_VsNICFZ23wAodgc8CZw or http://californiafancompany.com/double_ceiling_fans.aspx?gclid=CIWb_K_VsNICFUKewAodFccJ0A

I have cathedral ceilings in my den. My ceiling fan is on an extension rod that lowers it 5' lower than the ceiling. I would also get a remotely activated fan so that it's a simple way that you will actually use. There is a winter And summer setting that is activated by a simple switch. Try that first. If you are not pleased with the way that it works (and it makes a big difference). I'm going to suggest something out of the box...you can get clear, greenhouse plastic that is 12+' wide ...make a false ceiling near and using your beams. You can tack it with narrow strips of lightweight balsa or trim with very few tacks. We used a thick plastic that was clear over my sisters odd sized contemporary window..the plastic was so clear and the trim strips we used faded into the woodwork...you had to look twice before you realized that it wasn't just air space. We roll it up on the trim after carefully prying off in spring...wrap a sheet around it during summer to keep it clean , good luck. You're losing a fortune in heat like that.

I have a two-story home and the upstairs was always "out of balance". I had a new fan installed for my central AC/heat unit which runs constantly. Because of that, the air is always moving, so I don't lose either heated nor cooled air. Another thing, it appears you might could install a return-air duct up in the area which would move that air around. Just my ideas...
