Just joined the forum site, I burned wood in a Energy Mate for 17Yrs up till 1996, had an average use of 16-18 face cord per yr. House is about 2000 sq ft. Hot water heat. Installed a Weil-McClaine propane boiler in 96'. This year after feeding the gas pig, for the last 11yrs I am back to heating with a new Royal 6150 wood boiler. Hoping for less wood use and an warmer house. I have use the new boiler a couple of days in early Oct cool spell, seems to hold the heat real well. November will tell for sure when it finally cools down to wood burning temps.
