The Heat Commander has mostly performed as expected. The way the unit automatically controls the airflow through the firebox is really nice, and I rest easy knowing it's getting the most out of the wood I've loaded in. At the end of my second winter with it we've had an issue with the blower all of a sudden. The service technicians were not very helpful, and basically said well shucks I guess you have to buy a new blower motor. I was really hoping that after spending over $4k that everything would last me at least 5 years with routine maintenance. I'm hoping Drolet will offer a warranty replacement on the blower motor even though I am out of the one-year warranty period.
