New Hearth Build

[mepellet]

Looking for some of your opinions on a couple things. Would appreciate any and all advice!

Size
I am trying to plan a new hearth where a Napoleon 1100c will be located in a corner installation. Instead of going through every stove possible, I thought maybe some of you could share your wisdom. Would a 5'x5' area work for all stoves?

Materials
I am thinking of using 2 sheets of micore, then tiling over that. That will get my an R value greater than 2. Any stoves require more than a 2.0 R value on the floor?

Wall protection
None at this time. The way I read the install guidelines for the 1100c, I can back the stove up in the corner to 2” from combustibles (drywall) with double wall stove pipe.

Clearance to combustibles requirements of any given stove will alter the hearth pad requirements too. To categorically say that xx by xx will cover all situations would be tough. As each stove has a bit different requirements, that also translates into hearth pad requirements. A stove that has 2" corner clearances is much different than one that may require 8". Remember - in the front you are required to have 16" in front of loading doors.

Thanks for the reply! I realize that each stove is different but there has to be some size that would cover most situations. That is why I am reaching out the hearth.com members, since there are a lot of people with a lot of different stoves. Maybe I should re-phrase the question to be:
Would a 5'x5' tiled area on top of 2 layers of micore for an R value greater than 2.0 work for the stove you own in a corner installation?

 

[Jags]

I am guessing that a 10 x 10 would do it. Gotta remember the 3ft clearances for smoke dragons.
(pulling your leg a bit).

I am not aware of any stoves that require more than R2.0 but that doesn't mean that one doesn't exist. If you can assume that double wall will be used for "any" stove that you install...5 x 5 will probably cover the vast majority of stoves out there. But if you decide on a BKK with 8" double wall...all bets are off.

I think I understand your position, but there are so many variables that a one size fits all solution is tough, unless you are willing to do overkill.

The 1100C appears to need just ember protection. If so the micore layer is superfluous. For best rigidity and a level surface, I would lay down a 1/2 or 3/4" sheet of plywood, then a layer of 1/2" Durock NextGen (you can use 2 lyrs if you want extra peace of mind), then thinset and tile.

 

[mepellet]

Thanks Jags. Chimney will be 6" so I don't think an 8" stove will ever be going in its place.

Yes, the 1100c does appear to only need ember protection. A lot of stoves do not though correct? I want to be able to have some flexibility when/if we decide to replace it.

 

[begreen]

I would say the majority are under R = 1.0 protection. With a double layer of Durock NextGen you are pretty close.

PS: There are a lot of stoves that just require ember protection. The ones needing high protection are often bargain stoves or stoves with short legs and no bottom heatshielding or ashpan. I think the Hearthstone Homestead with short legs is the worst case scenario. R = 6.6!

Dang! 6.6!

 

[mepellet]

Does anyone have a stove that cannot fit in a corner installation on a 5'x5' hearth?

 

[begreen]

Hearthstone Equinox is 72" in a corner, but why worry or plan for something that is a non-issue. You will be generously covered with a 5x5 hearth.

Added Napoleon 1100c to my ember protection only stove list

Thanks

Curious what you mean by this raybonz. Are you on a quest to find ember protection stoves?

Raybonz- looks like you have been looking at a lot of stove manuals. Would you agree with begreen that the majority of wood stoves require less than an r value of 1 for the hearth?

Add the entire Napoleon line:
1100, 1100L, 1100C, 1150, 1400, 1400L, 1450 & 1900
Most if not all of the Lopi and Avalon lines including the Sheffield, Leyden and Arbor
Most if not all of the Buck and Country stove lines (3/8" non-combustible) etc.

IOW it might be faster and easier to list the stoves that require more than ember protection.

No not really I get feedback and collect it from forum members.. Stoves that have ridiculous hearth requirements are a pet peeve of mine..

Starting to look that way but there are a few glaring standouts in this category.. I feel this is helpful for new potential wood burners so the beat goes on..

Certainly is! Thanks.

This one cost me about $50. Used retaining wall block and filled it with 8x16 cement block I had laying around and liquid nailed everything together. I'm thinking about making it another block higher this summer while the stove isn't being used. I'm sure you could do something like this in a corner install.

 

[begreen]

Doggone, liquid nails or other adhesives are not advised in high heat areas like a hearth.

Good point BG would you recommend mortar for this application?

If I were planning a hearth, I would want to pick out the stove first, then plan the hearth accordingly. Unless you are thinking about changing stoves occasionally, the stove will probably be there for a very long time, maybe long after you move out. It's not unheard of for a stove to last 20 years or longer, then if you want a different stove, you may want to change out the hearth just because you are sick of looking at it.

However, even if the stove co. says 2 inches from combustibles, I would give the stove a little more room than that, or put up a nice heatshield for the back, then that would cover a lot more variables.

Have a stove already. Got a good deal on it. It is a smaller stove but we are not going to use it for the primary heat since we have a pellet stove that handles that job well. Planning on seeing if the wood stove works good for our purposes and if not I should be able to sell it for more than I paid for it, then get a different one. And no, I am not putting it 2" from the drywall. Going to be around 6" I think. Not going to put heat shields on the wall.
