I finally pulled the trigger and ordered a Dorlet 1800I, and hopefully will arrive by the end of the month. I also ordered a pre-insulated 6" liner. I'm expecting the install to be a PIA has I have to break out the exist clay liner in the chimney. I already have a ton of wood that by winter will be seasoned for about 1 1/2 years. I'm working on splitting it now, and already have 1/4 cord split without making much of a dent in the pile. We are planning on using this for supplemental heat to help lower our heating bill. any tips and advice would be appreciated.
