Everything Drolet Tundra - Heatmax...

[laynes69]

I spit my wood on the larger side, but it seasons 2+ years. I always burn larger splits in cold weather, and small splits in the shoulder season. In the shoulder season, I want a short, hot fire. Usually I'll burn limbwood, or I'll split down splits once or twice and make a fire out of those. This was 3/4 load after 10 hours this morning.

With the heat load on the house last night, the damper was open quite a bit. Locust doesn't offgas as quickly as other woods, slow and hot.

I have my damper set to open about 1/4" when the t-stat calls for heat. Thought about changing it to maybe and 1/8" so I am not sending so much heat up the chimney. It is nice having it set to 1/4" so when I build a fire, I can just walk over and turn the T-stat down or turn it off while I am at home.

@brenndatomu, can you rig something like this up for me...

Black locust. When I load for the night, I usually burn some locust but alot of Ash. If I'm working, I don't fill the furnace overnight, or there will be too many coals for the morning. When it's the weekend, I fill the furnace so I get my sleep. I loaded at 10pm last night, and woke at 7:30am to a 72 degree house with enough coals to load and walk away. It was 0° last night. Honestly, it's the first time I've gone that long in those temps, but I've been slowly tightening the house up, and I had primo wood.

@laynes69 have you ever tried hedge? I had some hedge drop into my stacks and it's dry and burns hot. I love it so does my stove

Yeah. Burned some that was in the stacks this year. Good stuff.

Sorry I'm clueless, you say hedgewood and I'm thinking you trimmed your hedges and are burning those. What is it ?

I just need to share the days event. So the wife was home from work today and I was at work. Told her she was in charge of the stove. So as I walked in the door she says to me I can't get the house warmer than 68. I said well did you put some wood on? Yes I did, she says. So I walk down stairs to take a look at the stove and it's 3/4 full of coals. I just shook my head . I asked her what the heck did you do? She replies I couldn't get the house to warm up so I kept putting wood on.. All I can say is she tried even tho I did give her some chit about it. I tried burning them down as much as I could but got sick of it. Even after burning them down for well over 1
hour I still shoved 1/2 a 5 gallon bucket out.. She tries to play redneck sometimes but you either got it or you don't.

Hedge hedge Apple monkey balls is same as Osage orange . It is super dense super strong and burns super hot . Osage is one of the best top woods possible in North America for firewood .Farmers used this around the perimeter of their property to secure it ,it also grows thick and has thorns making it ideal as a " hedge"

 

[jb6l6gc]

Sounds like mine. Mostly she's ok a playing redneck, just hasn't quite immersed herself into rural like style as I have since we moved here!

osage. or hedge apple

I gotta say, I really struggle (a lot) with how little heat comes of of these things with a belly full of SCREAMING HOT coals. Just blows my mind...just makes no sense

its the way the coals burn. its not the turbine going on in there running hot air across a plenum designed and built for high heat.. to take high heat. So when its just coals radiating heat the plenum can't get hot enough. If the door wasn't glass more heat would be gotten outta those coals. The plenum would get much much hotter during surge though. so would of course have to be built stronger. I guess its cause they need the heat to radiate away fast. Must be hard to do and still build strong/thick enough HE and top to fire box and such. I dunno

and the stronger you build it the slower it releases heat. The steel and HE box.. I would think.

 

[laynes69]

I get much more heat from the coals now, then when I had the old hotblast. While the coaling stage doesn't have the output of the offgas stage, it's still enough (at least for us) to keep the house warm.

Mmm, I dunno man, there are plenty of wood furnaces out there built like a tank, make Tundra look like a tuna can, but still heat well on just coals. My Yukon is one of them...almost 1000#.

 

[Digger79]

Quieted the noisy damper today.
Wired in a timer and a plug for power for multiple things a vacuum being one.

I don't really know either just guessing around but yeah Tundra doesn't get much heat out of coals only fire so must be the way the plenum is working/built. only variable really makes sense.

How much of the yukon is steel? how much is cast iron? I get a lot of heat of of the insert but thats because most the heat comes from the glass. lol the blower just blows around the stove of course for a plenum if you will. I bet steel puts of less heat cause it cools faster. Iron will hold it longer. Are the old boilers and stoves you say put of more heat from coals more iron or more steel built?

All steel...well, except for the 2-300# of firebrick in 'er. It is actually similar in design (except the secondary air system) to Tundra. The exact configuration is different, but the over all design similar

200-300lbs worth of fire brick? wow! no wonder it puts out so much heat. I was just thinking maybe tundra needs another layer of fire bricks but ud need to beef up the plenum some more to take it and increase the whole box size so not to loose volume in box. HeatPro is a monster furnace. maybe they put to layers in that one! doubt it. so you have multiple layers or just a giant firebox in that thing?

 

[brenndatomu]

200-300lbs worth of fire brick?

Yep.

Giant firebox...giant furnace actually! The firebricks are pretty serious too, "high duty" (3000*+ rated) 2" thick...very heavy

wow.. must be what you get when you start getting into 6-10k wood units. I seen some. pretty fancy. an huge. gasifying down draft boilers, lotsa cool stuff. Rocket mass stoves, Rocket boilers.

 

[Digger79]

30k wood gasifiers that power your entire home with 5 KW of power.

Air over the coals is the reason. When you get air under them they are like a forge. Remember spidey's posts.

Hahaha, yes who could forget spideys stovace...epic! I miss spidey...I checked on him...he got sucked in the vortex of the political forum...those guys rarely come up for air it seems.
I guess coals only give radiant heat well, not convective, eh?
