Thinking about a direct vent v. vent free heater for my upstairs bedroom. Would prefer vented, but am concerned about what's involved and if it's structurally ok to cut a 7" or so hole in my 12" 100 yo brick wall...
I'd hate to see you have to cut into brick that old.
Could you go through the roof? There are roof mount coaxial vent/supply pipes for direct vent units.
We used to have a direct vent stove in our fireplace that used two co-linear 3" dia. pipes that terminated at the top of our chimney 25 ft. above.
The co-axial vent kit is for fireplace inserts or in the case of Regency (& possibly some other mfrs.), DV fireplaces, that are vented thru an existing flue....
You caught me. I corrected my original post. I had my "Cos" mixed up. Apologies..I'm probably not understanding your comment.
We've had two different DV units, one freestanding (Jotul Allagash) and one built-in (Heatilator). Both could be used with coaxial flues. The Jotul was later converted from coaxial to co-linear for use inside an existing fireplace with ceramic flue. The coaxial setup for the (freestanding) Allagash is shown below.
Consider a core bore for round holes in brick. I drill some ridiculously expensive/old stone/brick whatever with my core rig. It cuts with a grinding action, no impact so damage is very unlikely.
There's NO way I would want to try to hold a hand held core rig with a 7" bit on it That's just asking for trouble.

No apology required. I wasn't trying to "catch" you and didn't realize I had. I just didn't understand your response and wanted to clarify that I'd definitely seen both coaxial and co-linear direct vent systems (my terms for them, they may have others).You caught me.

Structurally I wouldn't think it's an issue. Most times I've caused a problem in old brick has been from drilling inside-out.

Well, Since it is brick a vacuum base is out of the question. Trying to bolt 100 pounds of core rig to a wall is difficult at best. I think the best option would be to remove enough bricks to make the hole, cut the circular pattern on the outside remaining bricks and re install.
Any way you do it, it is not going to be a fun job.
Where does one get a core drill? Sounds like I'd have to pay to have it done...
I'm contemplating a free standing gas stove. Enviro ascot. My chimney is high and I've been quoted about $1200 just for the pipe up the chimney. Damn. So I was wondering. My dad has a gas stove, direct vent through a wall. Outside it's got just a small amount of pipe and the cap or whatever it's called.
Now I plan on putting the stove on the existing hearth, or pushing it in the fireplace a bit, depending on various factors. This got me to thinking. Why could I not drill a hole through the back of the chimney, which would be the same as the setup my father has, but instead of through the wall, it would be through brick.

I realize the drilling of a hole through the brick would be a chore, but the savings in the cost of the pipe would be good.
