So I bought a wood insert for my upstairs fireplace. I am about to purchase a flexible liner kit. I am curious about if its necessary to wrap the liner with insulation? It is centrally located in the house. I have come across different views on this. Most only doing it for exterior chimneys. All my chimneys run through the center of my house parallel to each other (3 in total) I plan on burning the wood furnace and the new insert mainly. My house is large so I needed the insert to help with take the edge off during colder temperatures or when we need just a little heat so it will be used often. Thanks for any input.
Agreed. Not to mention most existing chimney's don't have the required clearance to combustible's to allow a non insulated liner install. Having a professional sweep thoroughly inspect and properly clean the chimney prior to lining is regarded as the correct procedure. Good luck, be safe. Welcome to FHC.
This ^ ^ ^ Insulate for best performance and safety...don't play around with the fire you are bringing into your house...peace of mind is worth alot!
You've gotten good advice above. Also, consider that since this is an upstairs installation, your flue length will be shorter so the draft won't be as strong as a lower floor installation. The flue is the "thermal engine' that powers the stove. Insulating will increase the liner temp and will increase the draft ensuring good stove performance and decreasing the chance of smoke blowback.
Mine is centered in the house as well, I opted for a pre-insulated SS liner. As already mentioned better performance and peace of mind. I got mine from Fireside Chimney:Chimney Liner Kits|Flexible Chimney Liners , great helpful folks....
I will reinforce this statement from experience. Rockford Chimney online, great company yes absolutely insulate !!!!
