Hi everyone, We are fairly new to woodburning as a source of home heat and need some advice from you experienced woodburners out there. We are currently using a combination wood/oil furnace and it is a forced hot air system. So far, we have no difficulty starting a fire and maintaining a hot fire. What we are wondering is if it's possible to maintain a fairly constant temperature. We find that the temps in our house go up fairly quickly when we run the wood furnace, and that they continually rise despite our efforts to simply maintain temps. We're not sure if it's because we're not burning the wood properly, or if it's because the furnace is very old, warped and inefficient, and probably lets in more air than it should, or if the furnace is just too large for our needs. Basically, when we start the fire, we place the kindling and logs in a criss-cross pattern and we have the damper fully open to encourage air flow and get a hot fire going, and once we have a good bed of embers in the firebox, we load it with several large logs in a compact pattern and shut the damper to encourage a slower combustion, but we still seem to get a lot of heat from the furnace. When we load it with, say, 5 logs that are about 8-10" in diameter and 18" long, we get about 4 hours' worth of heat. Does this sound about right? Thanks for any help!
