:-S Fire on the wood boiler went out last night and did not re-ignite! Dam! Oil boiler was running when I got up this morning. Strange. I have had the Wood Gun be running when I got home from an eight hour day of work and it was warmer than it was last night. Quite a bit warmer. Why did it re-ignite then and not last night? The temperature was down to 20 Â°F. Seems like there should have been enough call for heat to turn the boiler on more often. Could my tank be working against my Wood Gun's design to re-ignite? In other words. Could the fact that the circulation pump goes off between the boiler and tank at 165 Â°F resulting in this: When the demand for heat is called for the tank now supplies the heat to satisfy that demand leaving the boiler from not having to fire for a longer period of time. The tank supplies the heat long enough that the boiler has not had to fire for several hours and gets to cold to re-ignite fire. Last night when I went to bed the Wood Gun and tank were both 180+ degrees. There was no call for heat coming from the house when I went to bed. I had a good size load of wood in when I went to bed. Slightly more than half full chamber. And when I added wood to it to get it to that point the boiler was running and hot. Any suggestions? I use to have the circulation pump between boiler and tank set at 150. I recently changed that to 165. Could this result in the tank alone suppling heat for a longer period of time? Resulting in boiler ceramics and entire wood chamber getting cooler and less likely to restart fire?
