Wood Stove Insert Advice

[CarpentersCure]

Good evening,

I am new to the forum and was hoping for some help. We are looking to install a wood stove insert into our current fireplace. We have narrowed down the make/model to the Osburn 3500, mainly due to the size fire box and square footage rating. Does anyone have any experience with this stove? I would also love other recommendations that may have similar ratings and cost less (if they are out there). Below is some information on our home:

- Built in 1991
- Standard ceiling height (8') and insulation
- Approximately 3000 square foot (1600 first floor, 1400 second floor)
- Chimney height and liner would be approximately 25'

I plan to install the stove myself and would love some input on what 6" chimney liners that others had success with. I have been looking at a 6" liner kit from Fireside Chimney Supply. The wood stove is located on one end of the house and we hope supplement most of our heat pumps with the stove. I have also attached a drawing/layout of the floor plan.

Thank you for any help you can offer!

Is this going into an existing fireplace or fireplace chimney, or a completely new freestanding stove installation? If it's an insert, go with a medium or heavy duty liner if they offer that option.

The Osburn 3500 is a beast of a heater. It's about the biggest that can be put on a 6" flue. It may overheat the room though while leaving the kitchen much cooler. The long hallway will impede hot air movement unless assisted with a fan in the kitchen floor blowing cooler air at floor level toward the stove room.

We have an existing fireplace with chimney, I’m sorry for leaving that out.

No problem. Can you provide a link to the liner kit under consideration? Does it include insulation?

Ofcourse, here is the link:

FireFlex 316L Smooth Wall Basic Chimney Liner Kit

Your FireFlex Chimney Liner Kit will include a FireFlex Smooth Wall 316L .011 thick stainless steel liner, 13" x 13" top plate with rain cap and appliance connector for vertical connections.The strongest liner on today's market!

My plan was to purchase it with 1/2” insulation

Sounds good, that'll do the job. It's a medium weight liner. What is the existing chimney liner ID?

Be sure to measure twice to ensure the 3500 will fit. It's a big insert. Measure the depth of the fireplace at 24" above the fireplace floor. It needs to be at least 19".

This was my next question regarding air movement and I want to make sure I am understanding it correctly. If you circulate the cooler air back towards the wood stove room, it will help with heating more area?

I have been very happy with a Blaze King Sirocco insert for the past 4 years. Put it into to an existing basement fireplace with a 25 foot chimney. The Sirocco is nice for a DIY install, especially due to the ability to connect the liner from the inside of the insert. We went with a rigid liner in several sections that connect together. Installing from the top of the chimney, one section at a time, is simple. Our house is larger, and undoubtedly drafter, than yours, however the basement insert does a great job of taking the edge off the heat bills (-:

Yes, it'll be replaced by warmer air moving along the ceiling.
The trick is to keep the fan on low so as not to mix the air and get a closed loop circuit (cool to stove along the floor, warm to kitchen along the ceiling).
Works best if no transoms.are present.
A fan on high will create turbulence,. mixing air, and leading to less hot air moving to the kitchen.

Cold air is denser than warm air and easier to move.
