Tonight I experienced what I would call the pre-stage to a boil over. I turned the shop fan coil fan to the on position. Calling for constant heat. I was in the shop for about 30 minutes and stepped out to, well, get another refreshing beverage.
Glanced over at the boiler and saw the float dancing from HEAVY steam. The aqua stat was still calling so I changed to 185 to shut down the blower. It was showing 187. I've had mine set at 190 +/- 10 since November 8, 2014. Never had an issue until tonight. Probably not an issue, but would like to hear a few comments. I was burning white oak from a 250 year old tree recently cut down. Yes. 250 year old white oak. Maybe the Gods have blessed me with exceptionally good wood. The stove was not overloaded and it is not THAT cold here. About 25 degrees outside. Shop was a toasty 74.
