Hello all,
I addition to my primary oil / Steam heating system, I been doing some searching for supplemental heat source... its a pallet stove... living space is 1500 SQ.... Stove is good for 2500 SQ... Manufacturer suggest 3 inch L type exhaust pipe, most installation of pallet stove pros suggest 4 inch exhaust piping... It would be probably $400 ducks more than 3 inch, $ inch don't require 3 screws at each connection.... As I have leaned, also having intake air for combustion from out side may be a better option, than burn air from inside of the house...
If anybody have experience in the field of having other home heating sources, such as pallet Stoves, please share your knowledge, suggestions, and experiences... thank you and best!
Thank you!

    thank you @ChrisJ ....I was told. 3 inch need 3 screws plus high heat glue...four inch would be much easier to maintain long run... I was wondering if there are efficiency benefits for having 4 inch vents for pallet stoves, plus outside air intake...
    Thank you!

    Is it a positive pressure, sidewall type venting system? If so I would go with the system that does not use screws and a field applied joint seal. A product with a gasketed system that is intended for and listed to the application, is my thought.

    The appliance manufacturer should indicate vent products that are allowed or certified for their product?

    What is the BTU size of the stove? The air for combustion needs to come from somewhere. Pulling all air from indoor can create some drafts and pull air down other vents in the building. I would go with the outside air kits that are sometimes offered as an option.

    I would highly recommend a top quality CO detector in the room. Carbon monoxide is odorless, and can be a silent killer. Protect the occupants!

    Thank you @hot_rod
    stove is 40K btu an hour. I would get intake air from outside, and wanted to use 4 inch L pipes installed since they are easy to assemble and clean. Absolutely agree on CO monitors, I literally have multiple installed in the house... and plan to add few more CO and smoke detectors. It has a built in controls and remote as well.. pic attached for info sharing...



    Thank you!
