I have had my Hyprotherm forced air stove for 3 seasons. It works great but I have seen and heard other users ask, how could it work better? I added a fan control on the small blower. Instead of full force under the coals, now I can dial the air speed. It’s easy to keep a controlled temperature, the wood last 4 times longer and my house doesn’t get too hot. I’m looking into adding a control on the main blower, too. I load the stove once for about 30 hours of burn time.
I’ve had my furnace since September, 2014 and I love it. I haven’t used a tri-axle of wood. I only load it twice a day, morning and night.
