We bought our house 2 years ago and it has a Harmon insert in it. I had the dealer come and he took it to his shop and have it a complete going through as it was very noisy. It turned out the exaust blower (I think that's what he called it?) Was going out. He showed me how to do a complete cleaning on it after he brought it back. So now this is our second winter (Wyoming) with this insert and I hate it!! The heat this thing puts out is, well not heat but warm air at best. I have tried every setting I can. It's pathetic. We replaced a wood stove up stairs last month with a refurbished St. Croix stove and it can cook us out of that room. I have it setup with a thermostat and it is truly a great stove so far. It has showed us how bad a piece of junk that Harmon is. So here is my question. Harmon is supposed to be one of the best from what I have heard. So what do I need to do to get this thing to put out some real heat? I was told by my dealer to run an air intake to the out side so I ran one using the hose he provided from isinde the house to out in the garage. It's about 5 feet long. I think this slightly helped but not much. Any other suggestions?
