Thanks for the info.

The idea of the faux chimney is for a heat mass. The visual enhancement is a bonus if I can pull it off properly on the second floor with our design.

As for sealing off the chimney, that was one reason I was curious if the brick could touch the pipe. I was thinking of taking the brick through the roof with the pipe and then closing it off against the pipe, and letting the pipe run a little longer past the chimney with a standard cap.

As for the clearance around the stove, what is a good safe clearance but close enough to heat the bricks effectively?

Hello all,

First post here and complete noob regarding this field. I'm in the design phase of our home and have been trying to learn the best way to add a thermal mass around our woodstove. Our build is a two story home. I was thinking of building a simple square chimney around the stove pipe all the way up through the roof.

My questions are:

1. What is the best brick?
2. How much space should there be between the brick and the chimney pipe (6")?
3. Can the brick touch the pipe?
4. Does the outside of the chimney bricks require any air gaps or can they touch framing / sheetrock / etc.
5. Is there a height where the bricks no longer serve a purpose. We have 10' ceilings, so by time this gets through the roof, it's over 25' tall.
6. Does this simple design even work?

I've attached two screenshots to show what we are planning. The first is a basic idea of what I was thinking to add mass. The second is the layout of how the stove will be placed near our foyer.
