Type II base for a big wood stove

Earthling

Hi all, I just bought a wood stove and will need a Type II hearth pad/base for it. (Type II because it's a big-a** stove that'll heat the whole house.) I could buy a pre-fab one, but I'm already over budget and would rather not spend an addtional 6 or 7 hundred.

So here's my question: Can I just put down three or so layers of durock or hardieboard, another couple layers up against the wall, and tile them with inexpensive ceramic from the Big Orange (or Blue) Store?

Stove is going on the lower floor, which has a concrete base with laminate wood flooring. The walls still have the 70s wood paneling, keeping them but painting them so the room doesn't look like a dungeon.

Any opinions / advice / wisecracks welcome.

Hope its not too big. Or the room its in will be roasting, before the rest of the house gets heat.

If it turns out that way beenthere, I can always go upstairs. The living/dining room and kitchen are right above it.

Got some pictures of the area?
There's no such thing as wood laminite.
It's laminite with a picture of wood on top or engineered flooring which is real wood veneer over plywood.
Adding all the tile board with no air space will just transfure the heat to what ever is under it.
If it's laminite it needs to float or it may buckle. So it needs to be cut out and a transition strip added around any platform you buiild.

Hi Joe, Here's a picture of the downstairs, stove will go in the far corner near the sliding doors.

So I just pull up about 5 square feet of the flooring in the corner and then put cement board down and tile it, that's ok?

Moved to Flooring forum.

That's fine but wow you have to deal with the wood on the walls.

Earthling

Gotta love that 70s paneling ... Yeah, I thought some more cement board against the wall part below the ledge. Or would I need it above too? Or rip out the ledge entirely in the corner, and cement board and tile all the way up to the ceiling?

This is not exclusively a flooring question, the thread should not have been moved here.

Floors and walls are not entirely in the scope of what HVAC people do. Flooring people often deal with both the floor and the walls. And know better how to handle them for what you ant to do.

You first need to know the installation clearance specs for the stove and your city code requirements. Asking here without that info isn't going to help you.

However, you need to remove the laminate in the area of the stove. The floor is a slab, so why did you think of installing concrete backer? You're already got concrete. Also, you mentioned 5 sq. ft. Did you mean to say 5 ft. sq.? That's 25 sq. ft., more like it.

As far as I know the wall needs to be "shielded" in order to reduce the stove's stated clearance minimum. A shield in made by furring out 1/2" concrete backer and leaving the required space at the bottom and at the top for airflow. Your building department will tell you what those are. You then apply a fire proof tile with thinset that comes in a bag and you're good.
