I just finished the long install of my Eko 40 that I bought from Kotly this Summer. I had an old Memco wood boiler that the Eko replaced. I miss the old Memco, but I am sure I will fall in love with the Eko. I have a 1000 gallon propane tank that I will start heating next weekend. Today I just wanted to fire the boiler and get used to all the functions. I guess I got it going just in time. It is snowing here and we have a couple of inches on the ground. Now I need to read the threads on tuning the Eko.
