I bought a digital thermometer that has a probe. Pretty much all day the out put has been around 340ish. I just filled the hopper and the temp has dropped and staying around 315. Why would filling the hopper cause a temp drop..?

I find this hard to believe. The hopper has absolutely nothing to do with heat exchange and is generally isolated from the stove mass. I can't imagine a load of cold pellets can cool a stove down to any measurable degree. The hopper on my Quad is plastic and the metal lined hopper on my Accentra insert is only moderately warm even after the stove has been running high all day long. I think the problem is in his data collection.
Really? 40lbs of cold pellets cooled the stove output by 25 degrees! Those are some really cold pellets to cool the entire stove off by that amount. I always put cold pellets in my stoves..no big deal. More than likely the auger stopped feeding pellets when he opened the lid and it took some time to recover. I agree he may have accidently moved the thermo in the process.SmokeyTheBear said:BDPVT said:SmokeyTheBear said:You in effect just added an ice cube to the stove.

His stove has a metal hopper and it can impact the temperature out the front a bit. Further he is also disturbing the air flow through the stove while adding the pellets. This is even before you try to figure out if he has that thermometer in the very same place for both measurements and that it is also protected from any air movements associated with his actions.
But in essence he is adding an ice cube to the stove.

I didn't say it cooled the stove by almost 25 degrees. He also is not measuring the stoves temperature, not by a long shot.

The original poster stated his temperature dropped by 25 degrees and stayed there. If your response is correct, the cold pellets wo
uld have to be in direct contact with the heat exchanger to possibly make a difference. If significant heat cannot transfer from the stove through the hopper, cold cannot transfer from the hopper to the stove. Does this make sense? I can't believe I am arguing this with you.
tjnamtiw said:340 degrees output temperature???? That's really high, WAY HIGH. My stoves put out about 180 max AIR TEMPERATURE. Do you have the probe just sitting in the outlet or is it suspended in front of the outlet? I could see if you have it inserted into the outlet that you would have that high temperature because you're measuring the temperature of the steel/aluminum (?) heat exchanger and not the air. That could also explain why the temp drops when you dump in a load of cold pellets. They cool down the stove's mass, which is reflected in a drop in the temperature of the heat exchangers.
A lot of people make this mistake by sticking a meat thermometer into the outlet tubes of the heat exchanger where it sits against the tubing, giving a false reading.
BDPVT said:Actually the heat would transfer to the colder object which would be the hopper. The effect of this would be a temporary lowering elsewhere.
The OP saying “and stayed there†is likely because he hit something while loading the hopper.
Your assumption is correct. Heat will always transfer to the cooler object until both objects equalize temperature. The hopper is always cooler than the stove. Correct? It is always cooler than the stove because it is isolated from the stove, otherwise it would be just as hot and your pellets would be burning in the hopper!
So which is it, the ice cube or moving something while loading the hopper? Or maybe the auger stopped when he opened the lid. Sorry, but this argument defies logic. Not trying to offend anyone, just trying to make a point.
