Been reading this site and some other forums for a while. Seems like there are some very knowledgeable and helpful people on this site. I have been around wood stoves for most of my life but don't know much about inserts. I am hoping to gain some direction. I have been researching many of the inserts out there and I am officially down the rabbit hole lol.

I recently bought a house which we are renovating. I have hot water furnace (propane fueled) base boards as primary heat source but would like an insert that will allow me to offset the fuel costs and plan on consistent all day / overnight burns. We live in the woods and the possibility of multi day power loss in the winter months is very real. I will be getting a whole house generator in the next year.

The current fireplace is inoperable due to damaged flue and missing mortar in the chimney. I am working with a 33w x 29h x 20d oddly angled firebox that the insert will be going in (pics attached). There is a 13" stone outer hearth in front of the firebox. I have a 2600 sq ft house with about 75% of the main floor being open floor plan and exposed wood ceiling (9' flat ceiling / no vault). There are firebricks inside the fireplace that may need to be demoed to make the firebox more square to accommodate the insert. Some have told me to not remove those bricks, others have said its not a big deal. I have a local chimney / fireplace guy that does great work ready to perform the install but he doesn't really have any opinion on what insert I should go with.

I am really interested in a bump out style insert for better efficiency and I like the way they look, which has me looking at the Osburn 2000 to the 3500 series (which ever will fit). I always heard put the largest insert you can fit in your opening. I am also looking at the regency i2450. I am open to suggestions based on what will fit in my firebox, I want an insert that is on the EPA list to gain the benefit of the tax break.

I am looking to spend up to around $4500-$5000, but obviously I would like to spend less. Any help or direction is much appreciated.... Totally lost at this point.

Those are, by far, the best pictures of a fireplace showing dimensions! Kudos to you, sir!

I just have a little Lopi Answer, which is great for my application.

Hahaha. Well thank you. I guess you could say I obsess a little over details.

In my experience the more information you give the better advice you receive. The devil always lays in the details… usually the ones people leave out. Lol

Folks will ask more about the chimney. Interior dimensions for a liner. Interior or exterior. Height.

It sounds like the hearth will need to be extended to meet the stove requirements. Agreed with your assessment, go for the largest insert that will fit and one that projects out onto the hearth a bit, and extend the hearth per the manual.

One dimension to note is the height from the floor to the hearth. Different inserts require different floor protection based on height. And by different I mean. Different R insulation values or just ember protection. Time to spend some time with manuals and see if any differences make one more appealing than the other.

Yes, I am guessing that the hearth to floor height here is >8", so the floor may just need ember protection. The mantel shelf may need shielding.

Approximately how tall is the chimney? One story or two?
