My house is a old new england colonial with an addition on one side, which is where my stove happens to be. The addition has vaulted ceilings, with one wall running up along side where the master bedroom is on the 2nd floor (see photo).

I'm wondering if I can put a vent or duct to draw the hot air from the addition into the bedroom. I don't have any existing ductwork in the house. I have forced hot water baseboards on the 1st floor, and electric baseboards on the 2nd.

I have no HVAC experience, so this is all new to me.

Thanks in advance!

A co-worker of mine does exactly what your thinking. You probably need to add a fan to pull the hot air through to the
bedroom. Passive heat convection without some fan assitance will probably not provide the desired result.
 
High ceiling's look great, make your room look Huge....but think about it, your heating the space you cant be in, great in the summer to let the heat escape up there, there was a reason MANY Years ago why we live in a small box.....think about it, and how many times do you look UP to enjoy all that wasted space?
I love your knotty pine ceiling, would love to build a room off my garage for a 3 season party room like that
 
Adding a vent would help as heat doesn't like to travel thru walls. I would also add a small fan to remove the cold air from the space you want the heat in. Pull out the cold air and the heated air will be allowed to replace it.

Check with your local code on adding the vent just in case. A friend was denied adding vents thru the wall, But was able to add an opening and called it a balcany. Had to add railings, And was much more expensive to do. They now leave the door open in the winter for very nice air circulation. Bedrooms are much warmer.

I have a very similar design with great looking but high cathedral ceilings. Not my idea, either, but came with the rest of the house. Ducting all that wasted heat to another room is a great idea but duct work should be insulated and have a good fan to assist in the air movement.

Or a room heat transfer kit.

Or a simple room to room fan

These are great, and at first I thought they were just what I needed... but unfortunately the wall space that my vent needs to span is rather large... about 2.5 feet, and these come up about a foot shirt.

Any other suggestions?
