Fireplace and outside air - Page 2

Just to clarify, you want a free standing fireplace or a woodstove?
I ask because many people use the term "fireplace" to describe a woodstove.
I use a woodstove and I bought a "fresh air intake" for it. I have yet to install the FAI because of having to put a hole in the wall.

Wow, I did not notice this is a really old thread.

This IS a really old thread. However, it still rings true. If you are burning air inside the house it must come from outside somehow. Stove, fireplace, cooktop range, hot water heater, etc. My point was that when you have a 30-50,000 BTU burner (or logs) it requires a lot of combustion air that eventually comes from the outside. Without a specific directed source of this air it filters in anywhere it can leaving those areas where it filters in colder. Having a specific external combustion air path minimizes this effect. I assume that you are on a slab or cannot cosmetically duct air nicely without a hole in the wall. Well, good luck with your project.

A duct that brings outside air directly to the fire is the ideal.

We heat a 900 foot home in southcentral AK 90% with wood and a propane backup. We use about 2-3 cords per winter.

anyway we have a hole cut in the wall behind the stove. through the hole is a flange on the flange is a 3 inch dia. tube. from the small tube sticking from the inside of the wall is some 3 inch flexible aluminum hose into the intake at the back of the stove.

No backfire protection (I have never seen on with backfire protection)

I often see similar set ups sold as fresh air kits for pellet stoves.

A lady i know had a free standing wood stove installed , the installers put in a vent somewhat behind and to the side of the stove, with a flap on it smaller but similar to a dryer vent flap.
