I have a quadrafire 5700 and last week it was 50's in the day and 30's at night. It was about all the stove would do to keep the house 69* or 70*. We are burning well seasoned hardwood. We have tried placing the wood in the stove different ways. We run the stove with the primary draft 100% open and the stove is usually between 300-400*. We also have a blower on the stove. This stove is not anymore efficient than the 25 year old earth stove it replaced. Anyone have any ideas what I can do to make it heat? Is there something wrong with the stove?
