A beautiful fall day in Pontiac Illinois
Followed by cold, frosty weather, the very next day
Can't complain too much though because we only fired up our rocket mass stove once so far, last night. With the recent damp days our concrete floors were getting cool and even though I bake and/or cook every day, which heats up the ambient air in the grain bin, it's not enough to keep the place warm for too long this time of year.
Still, we made it to November 4 which is over two weeks past our initial rocket mass firing of 2017. Not sure if the weather stayed warmer longer or we are just tolerating cooler temps better each year. Generally if it's 64 degrees or more in the grain bin we are comfortable. But last night the rain made it feel colder and so we broke down, cleaned out the RMH and set our first fire for the fall.
Prepping the stove for another winters' work does not take long. We removed the lid from the steel barrel and vacuumed up all the fine dust that accumulated in the fire brick tower (wrapped in Kaowool, a ceramic fire insulator) and down at the bottom of the barrel. Because the fire burns so hot, the ash is fine and a years accumulation equated to about a half gallon worth of ash.
Then we vacuumed ash from the take out point (black disk to left of barrel) which was minimal. That's the coolest thing about a RMH. There is very little ash or creosote build up in any of the stove pipes we have buried under our concrete floor, and by the time the heat/smoke gets to the main stove pipe leading out of the grain bin, it has been converted into a very clean steam.
It is the ugliest, most efficient heating device we have ever used.
After the cleanouts, we fired up the RMH and within thirty minutes the temp had risen 5 degrees and when we shut it down about two hours into the burn, it was 75 inside! Keith was walking around bareback and I found sleep uncomfortable. I love a cool bedroom. Now, over 24 hours later since firing up the RMH, the inside temp is still cozy at 68 degrees.
Freezing temps are expected later this week however, so we'll likely run the RMH some tomorrow night to keep the concrete floor "battery" charged with heat, which will be slowly released in the hours in between burns.
The stainless steel barrel, which acts as the primary conductor for the heat generated by wood burning, was hot enough last night for Keith to cook an egg on and warm enough today for me to rise bread and then finish drying a couple pair of jeans still damp from hanging outside.
Ah, if only I were so multi-talented.
Soon we'll be full blown into the routine of gathering wood every day to burn, stacking it in the mudroom to ensure a dry load for the next burn, scooping out the ashes from the wood feed chamber the day before, restarting the fire and then sitting close to the RMH for 2-3 hours every evening while feeding wood into it, but for now we'll probably only need to burn it every two-three days.
It's part of our ritual for bringing in the next season, and considering the person who stocks the stove ends up sitting/reading in the rocker next to it, we're not that disappointed to see this cool season arrive a bit early. Pros and cons, pros and cons.
