Please help me design a anti-stratification system!


I am renovating small 1000 sq.ft. 3 story condo, which is located in the mountains at 10k feet.
There is no forced air, just hydronic baseboard heating. The problem is the top floor, is, of course, much warmer than the bottom floor, summer and winter. The unit is facing south, with a lot of window area, so there is significant heat gain in the winter. To make matters worse, the top floor has an 11' ceiling, with the rest at 8'.

I would like to install a small duct and fan system that would force the top floor hot air down to the bottom floor. In addition, I would like to add some method of positive fresh air to help mitigate any inside polutants.

Knowing nothing about what is available today such as fans and controls, I need HELP! Would I be creating a moisture/humidity issue, and if so, how would I remedy it?

Thanks!

Do you have the space to add duct between floors? A chase somewhere, or closets on one floor above or below another closet?

Yes, and I think I can create an "exposed" chaise where I don't have closet coverage.

You could try a small inline fan such as this...

...attached to spiral or snaplock pipe.

If it were me I would get a small air handler and locate it in an out of the way place and run duct, that way the air could be filtered as well as moved.

What do you mean by "moved"?

What I meant was the air could be "moved" around in the building to prevent stagnating or "stratification".

A side benefit of having it go through an air handler is that there will be a filter rack with an easily accessible filter rack which, by using cheap replacement filters, will help clean the air as it is "moved".

1) The condo is 1000 sq. ft., ~300 ft./floor.
2) Open stairway from bottom to top.
3) Bottom floor is 1/2 basement or 1/2 underground.
4) Town is located at (10k elevation)
