Second winter with my Hearthstone Heritage and every single day I regret the purchase. Prior to this I had an old cast-iron stove that burned beautifully in any kind of weather. The hearthstone – terrible!! The only way to keep the stove burning is to have the catalyst disengaged at all times. Kind of defeats the purpose, eh? As soon as the catalyst is engaged, the fire dies to smoldering smoke and when it’s windy, like today, forget even using it. It smolders to the point that smoke pours out the back of the stove and fills my house. I have had my chimney people here twice. They assure me that everything there is set up and working properly. They advised me to test the moisture level of my wood. It all came in at about 12%. I feel completely gypped by this purchase. Can’t burn when I most need to. Must be home at all times to feel safe burning at all. Smoking is destroying my home. Anyone want to buy the damn thing from me? I’ll give it to you cheap. If hearthstone will buy it back, I’ll take half the purchase price and run – far far away from the company and anything with the catalyst. Expensive lesson learned.
