I have a fireplace xtroidinare 44 elite. It has a fan to bring outside air in to be heated. Since it runs from October to April I’m wondering if a more efficient fan could be retrofitted to save some electric. Cordless tools and rc cars talk about the efficiency of brushless motors but this runs on 110 and I’m not sure ac motors can do the same trick. I’m gonna try to get a amp reading on it tomorrow
