"Hump" temperature

I'll hump between 40 and 100 degrees.

I think it may have something to do with heating up the "stuff" in your house before actually feeling.

yep, I have that, its 62F ,very noticeable! 64F is a smaller hump. Definitely is there, not sure why.

No problem on teh cold temps but anything warmer than about 35 and I'd need to open a few windows to keep the house under 80*, even with only a little bit of wood in the stove. I haven't made a fire since yesterday afternoon and it's still 75* in here. Nearly 40* outside.

Exactly.

I agree it's the thermal mass. My house takes half a day to get the heat deep into the wall and ceiling insulation. Once the house is heated I need far less heat to keep the temp there or raise it.

Woah Nate, Sounds like your house is pretty friggin tight. That's awesome. I lose heat in this place like crazy. It's way better than it used to be, but I still have a few major projects to do to help tighten it up a lot more.

Yeah its been cake to heat with the wood stove. Funny enough when I was running the boiler and using the radiant floor heat it didn't seem like that.

Has anyone else found that there is a certain temp that is difficult to achieve, but once at that temp or beyond, it is quite easy to heat and maintain? I have found that when the house cools down to around 66 or 67 (16 to 17C), it can be difficult to get it back up to 19C (69F), but once you hit 20C, the temp rises quickly.

I found that same thing during the recent cold blast. The perimeter mass of the house got cold and the air in the house was stuck at 72 for 3 days after the weather broke even with the stove running wide open. Our old stove couldn't even keep the air in the high 60s when that happened. I think there will always be a point where it is cold/windy enough outside that you can't keep those remote perimeter walls warm with a stove unless you overheat the room the stove is in. It makes a big difference if you have a boiler or furnace to keep the mass further away from the stove from getting on the wrong side of the hump during periods the stove can't keep up.

My House looses heat like crazy too.... When we go to bed at night with the heater fully loaded the living room temp is about 72F, by the time I wake in the morning there is still a good coal bed in the stove and it still blowing out warm air but the temp is usually about 65F... and our stove works real hard to maintain that 72F degree temp when the outside temps are in the teens and below, I can easily maintain 72 - 75 in the LR with outside temps down to about 25F... I've got some more sealing work to do, especially around the windows...

My humps my humps my humps, my lovely charcoal lumps

I have two humps, one on the way down at 64 and one on the way up at 74. Very odd but easy to notice. Might be the thermometers.
