Hello,
First post here and was hoping to get some help. I've been looking at heat exchangers for my wood burning fireplace and decided that I would be better off cost-wise building one myself. I've gotten as far as putting together my galvanized piping system that would blow room air into the system, through the pipes sitting in the hot coals, and out the front of the fireplace. I'm in need of a fan that would work in this type of situation. I've tried a 6" in-line duct fan ((broken link removed) the DB206) with reducers to get the output down to the 1.25" pipe that goes into the system, but that doesn't produce any noticeable airflow out - I'm thinking because it needs some kind of backflow, but I'm new to the physics of ventilation. The pipes coming out are reduced to 1". I'm thinking I need a different kind of fan but I'm unsure what. I was looking at this type of furnace fan that I thought may work:

Anyone have any idea what I'm talking about and what I may need?? Thanks in advance for your help.
