Heat naturally rises, but you will notice a difference.
I agree with what you did. I too can feel the cold air pouring down my stairs. I am curious as to what that looks like. Having such a prominent grate is such a public area. Most grates tend to be along walls or in the corners. Out of the way. Generally stairs are right there in view when people enter. I think that is the most effective place for it. But the wife might not like it.

Take your time :!: We all can cut holes only to find cold air is heavier than warm air. Years ago 25 or more ago I too was experimenting. Luckily I took it slow unlike my neighbor. Another way to move heat from downstairs to upstairs is to pressurize the downstairs to help the warm air to rise. This can be done with small fans or in my case an inline energy effecient Panasonic fan. It worked well but the bedrooms got a little cool but other rooms where way warmer. The fan has since been reconfigured to pressurize the upstairs bedrooms, just trying to keep the women in the house happy. It was always in the latter configuration but a heating friend of mine suggested it. I thought it worked better but was out voted :x

Love those registers!! They are beautiful.

Yes, I've heard that some of them bring some pretty nice prices. I priced older ones when I was living in one of my former homes, and I found some of them to be quite pricey.

This thread is intriguing to me, folks.

I used to live in an older two story home (early 1900's). There were two vents cut into the floors of the first floor. I had a Vermont Castings Vigilant wood stove set up in my basement at the time, but I had a horrible time getting any kind of heat up into the first floor. I had the basement door open, but never was able to get any heat up to the first floor. The cold air in the first floor was actually going DOWN those two vents instead of up where I wanted it. By the sounds of the comments posted in these threads, am I correct that you have to have the vents located in strategic spots?? I guess mine weren't in the right places. I even had those little duct fans suspended in the basement ceiling right under the ducts to pull the air up into the first floor. They did very little. I was so frustrated that I eventually gave up because I was hardly saving any money in my electric heating bills. I did have a very nice and hot basement family room, though - probably around 80 degrees if not more! Im wondering if it was because I had a dropped tile ceiling in the basement......

The circle is required for circulation...
Cold air will push down the hot in a single shaft vent...
Add a second or third vent to the floor and watch the air move...
Bigger is better for natural convection...

CC is on the mark. How did that old quote go ... "It's not nice to fool with Mother Nature!"
  • Cold air is simply more dense. It weighs more than an equal volume of warm air, therefore undisturbed it seeks the lowest level. Let it or help it do its natural thing (get to the lowest level) and the warm air will fill the void where the cold air was. That's the circle CC spoke of.

I could have gone with a much larger grate in that area, but that is why I went with a 2" X 12" grate. It is narrow and long so it is not very noticable at all with where it is located. With the different styles and colors available (or you can paint your own), you can make it fit in with any floor or decor.

Something tells me that I must not have had enough vents in my floor, and I probably should have waited longer for the air to warm up. Good information folks!

What if a person were to use the riser of the last step instead of the floor at the bottom of the steps ? This would hide the register more but would the cold air make the turn naturlly is what I am wondering ?

Cold air is like water...
If water will do it, so will the cold air...

So with that in mind... if you have 2' of water in your kitchen, and you opened
your basement door, most of the water would probably
miss most of the top step. It would rush out so fast very little would hit the
riser/vent.. it would just rush down the stairs.

Air and water both share one common thing.
They don't like to work hard, so they take the easiest way out!

Thank God for the moon...
It gives us light at night, when we need it.
Not like the sun that gives us light in the daytime,
when we don't need it.

Sounds like the riser would not be the best option, thanks for the analogy.

That is a large register, I would know where to find my dog if I had hot air comming from one of those !

Have any pictures of your set up CapeCoaler ?
