What's a "Turning Neck"

[bnbhoha]

I have the furnace in a garage. The garage has been partially converted into a den type of room (will make it into a home thatre room). It currently has only one vent which is located next to the furnaces and it really doesn't keep the room warm.

One estimator said that I could intall a turning VAIN with the new two stage furnace I'm going to get to help warm up the room. I didn't get a chance for him to elaborate and won't have the ability to ask him until monday morning.I was hoping if some of you good folks knew what that was and how it works. Any other suggetions are also appreciated. Thanks

Sure he didn't say "turning vane"?

Maybe he means rubber neck?

Sorry, it was turning vain, oops.

Its something that reduces turbulance when air goes around a corner inside the ductwork. And no it won't make a noticeable difference in performance.

From the description you gave the register in question comes off right at the furnace. I would bet the contractor is recommending a type of scoop to catch the air and force more to this register. Takeoffs close to the furnace are short on air flow sometimes because of the velocity of the air coming out of the furnace. This all depends on the duct layout and we can't see that from here.

Steve are you saying turning vanes do not work? Turning vanes are a must in square 90's and help in radius 90's.

I like turning vanes but in this case I don't see how adding one will "help warm up the room". Unrealistic expectations are lurking in this post.

Turning vanes wil reduce the ESP (External Static Pressure) and increase the cfms (air flow).Now without the details we can't say how it will effect the OP's problem.

Here is my unscientific take on this turning vane issue: Taking a problem of noncomfort and turning it into comfort will take more than what a turning vane can accomplish....generally speaking. All those figures and calulations are nice but sometimes you just need to go with your gut.

one outlet isnt cutting it then i cant see any benneifit from a turning vain. it would seem to me the best bennifit would be to size the unit to the total load of the section of the house it has to heat and cool and add enough outlets to handle the room also. just replacing the unit is not the answer unles it is handled properly
