My Jotul is weak

[begreen]

As a youth learning sheetmetal work, I complained a lot about getting caught on fishhooks from my sloppy cuts. My boss frequently would comment that a poor worker always blames his tools.

My son told me (of course talking about someone else): it's not the bat, it's the batter.

That does get mentioned back to him regularly now...

Yea..."it's the Indian not the arrow" was the battle cry for years until someone discovered the revolver.

But if you put the rounds in backwards and don't know how to use it, those advances in technology may lead to the revolver being better off as a club..................................

Can anyone with a 550v2 like mine offer info as to what temps I should be shooting for in the box. I have a digital “point and shoot” infrared meter and I get around 750* if lightly and loosely packed with lots of airflow. The logs in the rear of the box rarely burn off and seem to smolder compared to the front near the glass which seems to burn brightly and completely. This is with firebricks or two year old small sized white oak splits.
1 yr old oaks will get to about 600* if loaded similarly but the burn pattern is the same. Rear doesn’t burn same as fronts. So far temps are better if I keep splits off rear wall as airflow seems to suffer.

a point and shoot thermometer does not work properly to measure temps through glass in the firebox.
The fire is likely 1500 F or so...

Our Jotul F600 burns the up front wood first and burns it's way to the back. This results is usually leaving some coals that can be pushed to near the glass front to where the main combustion air enters and is handy for stoking the next load of firewood.

Understood, but it should give a fairly good reading outside the box and in the air circulation exit point ?
How would you get a reading from inside the box ?

Firebox temps are roughly double the stove top temps.

 

[stoveliker]

Yes, those IR thermometers are decent outside the firebox, assuming it is some dark (cast or painted) metal.
Inside the firebox: for home-owners approaches, I would say that's not possible without drilling a hole and having a thermally (ceramic) protected thermocouple stuck in there.
Opening the door and shooting with the IR will affect the tempearture too much due to the air rushing in to be reliable.

Then again no one controls their stove based on internal temps. Measure at some fixed point outside, preferably a point where others with the same model also measure so you can compare, and regulate the air based on that.
That may result in "box temps twice the top temps" to be valid for this model (I don't know, but Todd is knowledgeable), but this won't be transferrable to another stove model (with another design).

I have a Jotul C 550 V2 Rockland. Newly installed in December. I have only done a few burns but this week I have been burning since Saturday. I let it go cool overnight so that I could shovel out ash this morning. I started a fire around 9:30 AM and it is 1:00 PM now. Here's some pics and temps...

Temp probe is at 438 F. I ramped it up to 1/2 open because it had cooled off quite a bit since I last checked. This is reading the thermocouple that Jotul provided with the stove.



Temp on RH face frame



Temp on LH face frame




Temp at top of face frame




Temp on the surface of the stove pipe going out of the stove at the top where the air circulates from the blower

Where is that thermo couple. First time hearing of it. And what is it reading to ?
Thanks for the pics. I’m getting similar numbers from outside/around the box. I just don’t get much “heat” from it into the room.

Is there a block-off plate sealing off the damper area around the flue liner? That makes a big difference in heat outpup.

There is not a solid plate ( my tinsmith is ill) It does have two bats of insulation blocking any openings.

When my stove was delivered there was a cardboard box inside the firebox. The box contained a "catalyst temperature probe" attached to a wire with a two pronged plug at the end. It also contained a "catalyst temperature reader".

See your manual page 4 for contents of the box.

Jotul C550 V2 Manual Link -- Click Here

On page 10 of the manual it shows you where and how to install the "catalyst temperature probe" at the top of the firebox.
On page 18 it shows you how to connect and use the "catalyst temperature reader".

I reloaded the firebox around 3:15 PM today and here were my temps about 15 minutes later.

Thermocouple probe temp is 626 F.

Temp of internal flue pipe surface is 568.

I dialed it back to 1/2 air flow after taking these pics.

Are you getting good usable heat from this stove?

 

[flossy21]

Are you getting good usable heat from this stove?

Yes - it is my back up and it is located in the walk out basement. We have a heat pump with a propane furnace for our primary heat. This definitely takes a lot of the load off of the heat pump/propane furnace. It heats the basement area which is about 25' x 12' up to about 75 or 80 F and pushes heat upstairs because we leave the door open to let heat come up into the middle level. The chimney is in the middle of the house and it definitely warms the masonry as well.

Now it's about 5:30 PM and here are my temps.



Thermocouple at 480 F



RH face at 493 F




flue pipe at 446 F

Never saw the manual or the probe. All news to me. Thanks for the info. Maybe it was an option. But the manual seems to sound like it’s standard.

I’m nowhere near those temps unless the flames are fully engaged.
