Bigger stove but small hearth

[zatnip]

It should look cool I think. I have a similar set up. If in doubt you could make a mock up of stove using cardboard if you feel like you need to set it visually.

Sorry to revive an old thread. Could you comment on this specific setup and clearances? I am looking to get a bigger and more useful stove than what I have currently. The house I bought came with a Tiny wood stove 3kw in a 32”x32” corner area. Looking to find a stove in the 50 - 60 kbtu range that I could place in this location and struggling to find options. Its this or ripping out an old ZC fireplace in another room for a more efficient setup, but would think I would have to wreck out the stone hearth to do so.

Hi, I moved this to the main forum because the solution may not be Hearthstone specific.

A larger stove might work if it has close clearances and it fits properly on the existing hearth. This may require extending the hearth at floor level a bit with simple ember protection. Or, the current hearth can have more stones added as an extension at the same level.

Tell us more about the house and the room this little stove is situated in. How many sq ft in the house? How many in this room? How open is this room to the rest of the floor?

House was built in 1982. Approx 1950sqft. Layout posted. Walls are in blue. Red Portion of walls are open. This stove is where the yellow square is, open ZC fireplace in purple. The idea would be to keep the main living areas of the house warm. Immediate room is about 240sqft, with the adjacent living area connected by a large opening being about another 550sqft. Exterior walls are probably R7 insulation at best and the ceiling is R18 at best. The house warms really well in the sunlight even with temps in the 30s especially the room with the stove.

About the current setup: Floor should be nonflammable. Its porcelain tile on-top of the concrete slab foundation. Expanding the hearth is fine with me. What cannot be seen in the first picture is a door next to the hearth.
Some questions I would have about clearances:

Based on some reading in manuals on drolet stoves, I would not be able to install a stove and use heat shielding based on the shield needing to extend 18in past the edge of the stove. - Is this a true statement?

If there were enough room to meet clearances without shielding would the window or door pose an issue?

Any stove recommendations? I have been browsing Drolet because I can purchase them direct.

The wall shielding is probably a moot point. It may have been applicable for the tiny house stove, but a clearance reduction may not apply to the new stove. Note that the current shield should have at least a 1" gap at the bottom to meet NFPA211 requirements.

It sounds like the flooring qualifies for ember protection. What is the hearth radius? I'm wondering if a Vermont Castings Aspen C3 would work there.

Looking at the floorplan, the location of the ZC fireplace is better. Do you know the make and model of this fireplace? What is the fireplace lintel's height? Please post a picture of it too.

Yep. Based on what I read on the current stove the heat shields are not needed and based on what I have read they are installed incorrectly as it is. Hearth Radius 32” on each side and comes out to about 38” in the center.

The ZC fireplace is a Majestic model of some type. I pulled K186499 off the plate but nothing else since its pretty dirty. A plate about glass doors is attached.Lintel height is 24” from the fireplace. Current unit is 36” wide at the front and about 19” deep. It is installed in an exterior chase. I am a little worried that a new high efficiency unit would mean a complete redo of the stone which is where I thought a bigger stove might be less costly and less intrusive.

Look carefully around the fireplace opening rim and clean off the name tag that shows which Majestic model this is. In the past there was a Hampton stove that would have been able to rear vent under that lintel but it is no longer made. The Jotul F602 is close. There is a possibility that a skilled installer could open up the chase outdoors and remove the insert, leaving the stone facing. The replacement however, would need to be a close fit for that to work.

The fireplace is a majestic M36AO. When you mention a stove there, you mean to place on the hearth and vent up through the existing chimney?

Thanks. The manual for this fireplace prohibits any component not made by Majestic, so installing an insert is out.

Yes, that was the thought. This would require putting in a 6" liner inside of the existing flue. The issue is that 24" is a low lintel. Most rear-venting stoves exit an inch or more higher. The Hampton H300 with the short leg kit would have worked but it's no longer sold.
