    I need more draft for my PH, going to wrap my liner wondering if that will do it.

    I'll let you know. I had draft problems with my PH and insulated my liner a couple weeks ago. The first two fires looked promising, but they were wimpy fires so I can't claim victory just yet. I did notice the following during these two warm weather burns:

    1. The fire used to take forever in warm outdoor temps to get fully established. After insulation, fires caught and heated quicker.
    2. No backpuffing to report as of yet.
    3. Still some smoke spillage out the door, but seemed to be much less once the fire got going.

    What sort of flue setup do you have - height, liner, exterior/interior, horizontal sections??

    Stay tuned......

    to run better.

    Just my experience,,, I have an uninsulated liner and I have great draft and I only clean it once a year with marginal wood. I doubled the size of my insert this summer for longer burnrs but the old little one heated just fine.

    We have seen cases in the past where this has made a difference. Are there any confounding factors in this installation like chimney height?

    I have a short chimney, with the liner only going about 4 feet up then dumping into a clay flue. I had lots of draft issues, hard starting fires, smoke puffing back into the house when opening door and slow restarts when adding fresh wood. Mornings the flue would be cool and take a long time to get going again. The air control worked but not as well as it does now. I installed a insulated liner to the top and all issues seem to be gone. Not sure if the insulation did it or the liner all the way to the top did it. I think the insulation keeps the liner hotter and enables faster warmup so the draft works better.

    Just my 2cents :)

    About 16-17' from the stove outlet to the top 8x8 terra cota lined with a 5.5" simpson. one 90 that is being changed for two 45's. First fire tonight, looks much better, started easier, lots of open door spillage still, but its 40f outside so hopefully it will only get better with the 45's and cold temps.
