I fired up the Greenwood this afternoon. I have been waiting for it to get cold enough, we have just been using a Lopi Liberty that I installed in our family room about a month ago. I made a few changes to the Greenwood system. I installed an air scoop and another bleeder, changed my heat exchanger from a 20 plate to a 30 plate. I also abandoned the 2 radiant zones that were sucking so much heat and installed CI radiators in those loops. I hope these changes will cut down on my firewood. I used about 8 cord last year. I have about 9 cord up this year that is better wood.
