Sometimes tinkering can make good things happen. The blower fan upgrade on my outdoor wood boiler is a case in point. The stock fan that came with my Portage & Main unit did a good job most of the time, but sometimes the boiler just seemed to need more air. Sometimes, but not always. That’s why I looked around for a variable speed fan that put out more air than the stock one, but could also be throttled back for those times when less air is more efficient.
