My Hearthstone Clydesdale woodstove had a rattling blower system that FINALLY broke after years of service. Replacing the blower was going to run me about $200 and would require removing the old blower system and putting in the new one. I am SO glad I chose to buy two of these blowers instead! They are powerful! MUCH more powerful then the system that came with my stove. I actually put them on the top of the stove with the fan facing outward, so the intake draws the heated air from the behind the stove and blows it out into the room. I am going to need to burn a lot less wood because of the increased efficiency, which is a win win all around! Great purchase. I will need to create some kind of cover screen because I am using them in a reverse fashion from how they are designed, but I don't think that will be too hard to do.
