Product review (2 stars): Only works when the fire is roaring
We heat our house with a wood burning insert and the Valiant sounded like a great replacement for using the electric fan that is part of our wood burning insert.  I thought it would also guarantee that we'd have a fan when the power is out.  I'm very disappointed to have discovered that the Valiant only works when the fire is roaring.  Anyone who heats with wood knows that there are times during the day, and especially at night, when the fire is banked. At those points, the Valiant stops spinning and we are forced to use the electric fan again so as to distribute heat through the house.  If the company ever manufactures a fan that will work at lower temperatures, I'd be interested in that.
