We just got estimates from a place that was having a "warehouse sale" on gas fireplace inserts, which we want to put into our inefficient wood burning fireplace, with a brick chimney and a small opening of only 20x30". They said they were closing out their standard pilot light models and the only two they had that would fit our opening were Heat N Glo Supreme I30-SP and the Heatilator NDI30-SP, both in bronze surround. They said both models were about $600 off regular prices and want to charge about $3,500 (for the Supreme) or $3,200 (for the Heatilator) installed, with us providing a chimney sweep and us providing an electrical outlet inside the back of the fireplace opening. Also there would be a fan on both models, but no remote. Is this a decent price? Not including installation, It breaks down to about $1,800 for the insert, front and surround for the Supreme, and about $1,500 for the Heatilator. So installation, including a flex liner, horizontal gas vent and permits would be about $1,700. Is this a good or great deal on the insert and the installation? Would we be better off finding our own, better priced installer? Or can we find just as good of deals when we get closer to fall and winter? We don't want to buy now unless we save a lot of money on it. Which is the better, more dependable model? Looks like both are made by the same parent company with same warranty and 32k BTUs. Thanks much for any advice you may have!
