    I've got a progress hybrid, that uses room air. I'm considering a tighter house (here it's called a deep energy retrofit, I've got to re-shingle anyways, and I thought I'd up the insulation and reduce the infiltration). My understading is an Outside air kit (OAK) will turn the PH wood stove into a sealed combustion appliance

    Anyone have experience with this conversion? I know woodstock sells an adaptor. My stove is in the center of the house. To use the OAK I'd need a 12 foot horizontal run. Anyone know if this poses a problem

    It should be okay. An OAK can work out really good at times. We've had an OAK and thought strongly about putting in another one when we installed the Fireview but changed out mind.

    Like you are doing, we super insulated this old crate. Also put in new doors and windows. However, after doing this, I think perhaps an OAK might help us a bit but first we are planning on putting another 4' onto the chimney. We get along okay but just a few times I've noticed a bit more draft would help. I say go for it.

    Dennis, if you have now insulated your milk crate you have gone to far!

    Still working on that one pyroholic! Actually, I do use a hot seat on the crate which keeps my backside from freezing or waffling. ;lol

    Just found a hot seat that I've had for years, thought it looked like a great thing for vertical splitting. I always split vertical too, unless I am splitting right out of the back of the truck.

    In reality none of the stoves are completely sealed combustion. There always seem to be hidden intakes usually for the window air wash system. Additionally these are not regulated by the the main control. In a very tightly sealed house the OAK is a necessity though just to get your draft properly working.

    Maybe you could see how it works after you do that job. Maybe you won't really need it.

    Maybe none of the woodstocks but my last two stoves received 100% of their air from the OAK connection snout. They were as close to sealed combustion as you can get.

    An OAK can only be a positive change. Sometimes adding it doesn't fix a problem but we've never heard of the OAK system causing a problem.
