Just wanted to report my experience with a new EGR 250 furnace. Had a real problem keeping the fire going when I started out. Kept a propane torch handy and it would light up quick but was a hassle. The specs call for wood cut small so that is what I had done, 4 to 6 inch, dry, fir. OK fir is not the best but I had a few dead trees to dispose of. Wood would turn to charcoal and not restart when the fans kick on.
The EGR 250 was larger than I needed for the house but have a shop in the planning stage that it will also heat. So that was causing long time periods between burns. Reset the temp range lower to decrease non burn time. The real fix was to use larger wood. After two cord of the fir I had split small for this unit I got to larger fir I had split for my old furnace and that help a great deal. Now I am in to Oak that had been split larger for my old furnace and have not restarted for a few weeks.
Now the good part. My old Heatsouce 1 was using a cord of wood every two weeks. With three months and a few day on this furnace I still have a little left of the third cord, using less than half the wood. Some of this may be from replacing the hot water lines going to the house with Dual Pex Flex. I know I was loosing some in the underground lines I had because it would melt a light snow off in a line to the furnace.
So overall very happy with the unit. Requires more maintenance, and more picky about the size and type of wood. But I am getting old, (68), and cutting half the wood every year is sounding good.
