What Is In Your Stove Right Now?

[weee123]

I wish! After adding the damper it got better, but still is usually 150 degrees different flue over stt (with the blower running on high). Flue at 10% open air 1/4 open with a full hardwood load I'm over 800 flue and 620-650 stt.

There's several people here that are regular posters who have the NC30. Any of you guys able to run stt equal to or higher than flue?

In the name of science I am going to see if I can get this to happen with the damper closed as far as I can, the air open, and keep it running (with the magnet off the secondary air that I just put on...) It's still -5 out and I'm not going outside, so I might as well do some playing with it.

I should remind everyone about my flue situation too. 24' total flue height, 4' horizontal run 42" above the stove. It seems like I fight weak draft until it's HOT, then it gets really strong when it's hot, then lose it badly as it cools. I did a bunch of experimenting when I first installed the damper and I think it was @Gearhead660 who at one point suggested to try shutting the damper before the air control, which was better than shutting air down first.

How did it run with the secondary partially blocked?

Fine. Burning down coals with small loads right now, so I haven't really tested it properly yet.

I went back and re-read my dissertation on the damper experiments and ran a little experiment with one of my small loads and am convinced I won't be running stt as high as flue.

What are the STT’s with the blower off?

What are the STT’s with the blower off?

If I'm burning I need heat. If I need heat I want air moving heat off the stove into the room where it can then slooooowly matriculate through the house. I don't understand having a stove without a blower running. Not being snotty @Todd, just never considered burning without the blower. Only time the blower is off is when the stove is cold and on a cold start. Once stt hits 250-300 it goes on and may not go off for weeks.

So, coals are burning down. Started flue at 320, stt at about 210-220 blower on. Turned blower off for 15 minutes, flue down to 293, stt about 240. So with the blower off in coaling stage they are closer, but stt is still under flue.

Magnet covering about 1/3 of secondary air put back on and blower off. 3/4 load of shoulder season wood loaded on lots of coals, air & damper full open. Practically exploded. Flue to 800 quickly, closed damper to 45 degrees, continue's to rise slowly, 850 flue, close damper to about 1/4 open, flue drops to 824, stt about 360, wait, flue rises to 850, close damper to about 10% open, flue drops to 772, stt 500, wait, stt to 580, flue starts to rise again, at 800 flue & about 625 stt shut air to 1/2 open, flue holds steady & stt to 650, wait, flue rises to 810 & stt to 665, close air to 3/8 open, flue holds & stt to 680, wait, air to 1/4 open, flue slowly drops to 770 and holds & stt gets to 690, wait, flue continues to slowly drop to 755 and holds again & stt still 690. Sun is dropping, house temperature is dropping, blower turned on, flue temp holds at 755 & stt drops to 650, wait, flue drops to 740 & stt to 620. This was over 35 minutes total. Now temperatures will continue to drop until I open things up again. Seeing as this is shoulder season wood (pine, aspen and silver maple - css'd in '21&'22 outside, moved into the garage in August) I will probably cruise with the damper at 1/4 open and the air about 3/8 open until it really starts to die and I open the air more to help it burn down.

Currently cruising damper 1/4 open, air 3/8 open, flue back up to 765 and dropping slowly, stt at 550.

Yes, blower off the temperatures are closer to each other. For my setup flue is still higher than stt. My overnight hardwood load may be better because it is a full load and better wood. I am curious to see what happens tonight with the secondary air partially blocked so maybe I can get to my overnight settings faster. Based on what happened with the shoulder season load I suspect I need to block off more of the secondary air.

Reloaded again, 275 STT. Blower has been on a higher speed all day than normal so stove temps are falling faster than usual. Big chunk of ash, big chunk of cherry, a small split of maple with a black cherry cut off. The ash and cherry took up most of the room in the stove.

Yes, the blower does make a big change to your STT as was just shown. I’m surprised you are running your primary air so far open. I run my 32 at 10% open or less. Anymore and it’s wasted heat and fuel up the flue. Also it would definitely overfire if I did.

Are you able to cut the air back more than 3/8-1/4? In my limited experience the more the primary air is open the more heat gets sent up the flue. Does the fire die if cut back more?

My 32 isn’t able to be equipped with a blower and is purely a radiative heater. My previous stove also didn’t have a blower but could’ve been equipped with it. They both heated the 1600sqft bilevel house just fine although one does do it better than the other.

I was just trying to say the blower will affect your temps just like you stated above. They will come closer together without the blower. Not saying you shouldn’t use it.

Early in the burn I can have it shut further, but then the damper would have to be further open. Horse apiece, but the damper closed more and air at 1/4 open is a healthier fire.

Through trial and error I know to not have a pile of charcoal and smoked glass in the morning I have to have the air 1/4 open and typically damper 1/4 open. If it's super cold I can have the damper a little further shut. If it's warmer outside I might have the damper at 1/2.

I think that darn horizontal pipe really screws me.

Yea 4’ of horizontal is a serious amount. Does it go through the wall to a tee outside?

Been running smaller loads after work to be able to keep the STT up to get some heat throughout the house. Currently 610 STT and 550 flue temp.

 

[vatmark]

Oak burning as usual. It is much colder here than usual....in the 20's. Started with cold stove and 65 degrees for our main level open floor plan. Main level stayed around 71-72 all day. Normally it is 74-76 when temps are in the 30's. Suppose to get down to 10 tonight. That's pretty cold for here.

After the bunch of oak knots this morning and a 40% load of pine around 4.30 now mostly locust.

17 now, the forecast low is 13. Upstairs is 71.

 

[all night moe]

Burning mixed hardwoods throughout the day. Mostly uglies and shorts. 5-6 at a pop and 2-3 splits. In the dragon's mouth on average of 3hrs. Been in single digits all day with accompanying wind chills. Going down in the lair soon for a feeding of red oak. Will be all limb wood. 2-4'' dia.

 

[bigealta]

Got 3 oaks in on a pretty large coal bed. Lit up immediately. 2nd pic about 30 seconds in. 1 minute in have draft set to 3/4 closed.
Edit .....Hey that looks more like a piece of cherry and ash on top.
So idk whats in there i guess?

Bottom is oak. Small dia leader or large limb wood.
Beautiful flame out in the 2nd pic.

Don't want to spend time to figure out why my phone makes it so blue

 

[NickW]

3 ash, 1 beech, 3 ironwood. Trying it with the secondary air partially blocked...

 

[thewoodlands]

It's 6.2 out tonight, the basement temp is starting out at 79 with the temps up here 68 & 70. The overnight load has four beech with three splits of ironwood in the wood stove.

 

[Dieselhead]

Full load of Oak, cherry and maple just went in. Great combo for tonight’s single digits. Had barely any coals from todays spruce load so I have a little catching up to with house temps before I catch some 💤😴

☕️ time yet?

Blue phone .....I mean flame .....technology.

And that's the Chinook in action? Beautiful flame show. Whya gotta do this to me? LOL....4 stoves.....

No...my thread. "4 stove plan."

Come to the dark side.. we have flames too 😉
