This is my third wood furnance in my home since 1989. I felt really good buying the HEAT COMMANDER furnace because of the stated advances in a "modern furnace" that is EPA Certified. I bought this in August 2023, but due to close to fall heating season in Michigan I decided to wait till next year to install and use my old furnace for the winter of 2023. I also had all my wood cut for my old furnace which had a much larger firebox and I was not going to re-cut my wood to fit the smaller HEAT COMMANDER firebox. I finally installed my new HEAT COMMANDER and had first burn on 05 October 2024. By the way, I found out your warranty starts the day you BUY IT not when you install it. My first problem was a broken ash door and DROLET readily sent me a new one. My second problem in the middle of the winter was my GREEN LIGHT stopped working and after an $85.00 dollar bill received my new light. Your electrical warranty is only 1 year and I did not install it until after 1 year. I installed it myself and now everything works OK. I am amazed the furnace DOES NOT come with any FEET to keep it off the floor and puts the ash door right on the floor. I am 74 years old and that makes opening the ash door very hard for senior people. I solved that by mounting the furnace on a steel platform dolly. The furnace weights around 700 pounds so the dolly makes moving the furnace very easy. I am very disappointed that I cannot get but 3-5 hour burns even with oak firewood packed in the small firebox. I also fought with smoke backup when low fire is present. After living here for 35 years with two other wood furnaces I have never experienced that. I solved the problem by purchasing a GEMI draft inducer. I have talked and consulted with many "wood furnace" experts and DROLET themselves, but have not received any solutions. I may have to move my old furnace back and put the DROLET in my barn. I am not satisfied with the help or the furnace and cannot endorse it with a good conscience.
