Scott's reply - Good, I think it is worth pursuing considering my extensive experience with fireplace inserts and wood stoves.
Most systems I've read about consisted of underfloor ducting of extertior air to a standard placement interior feed tube. In every case these builders found it resulted in horrible back-draught issues, perhaps because intake and exhaust were on different sides of the building creating a pressure differential? That last part is speculation.
Scott's reply - Chris, I dont know why any back draught issues would be caused any differently by the intake air source or location. Whether it be outside
source or the interior feed tube, if a hi pressure hits the outsside or exhaust "vent", flow is going to go backwards regardless of where the intake is.
So if you were going to have a severe back draught event, I would rather funnel it to the outside instead of having a flame shoot out into the house.
I do know that most people going down this road have abandoned it. Care to do some further bush-whacking for us Scott?
Can you really tell me that we aren't dealing with suspicious baked goods? And then there is this tiny ad:
