Review: workd=s well and has simple to use controls. Keeps the room warm when it was constantly cool before.
Review: This thing is great! We don’t use it in the traditional manner. We have a wood stove in our basement and registers cut in the floor upstairs to let the heat up. We got one to put in the register right above the stove and it works great. As it warms up downstairs it turns on and just pumps that heat up. So far it’s proven to be very durable and it’s not very loud at all. No different than a fan
