Have You Noticed This With Your Harman?

I was assuming number 6 was the stove temp number. if it was the feed rate..that would make more sense

Oh, looks like you were right. It was heat setting 7. Not sure about that advice though. If an appliance is rated to do something, then it should be able to do it. I'm curious as the the reason the dealer recommended that, aside from there is a black window issue and they are looking or an easy out.

Stove temp number 7
Feed rate 4 and 3 and half

I actually had to turn down the feed rate
Down to 2 because at 3 it wasn't burning the pellwts completely

Where is your temp probe? If it is in a location that is more affected by the extream cold, ie next to a cold oak, or near a drafty window, then the stove might have been ramping up because it thought your room was colder than 72.

My p43 is running pretty hard right now with the temps between - 10 and - 30. At - 30 she is just about full tilt, running on room temp auto, feed rate of 5. Going through 2.2 bags a day. (of 2.4 theoretical max)

When burning that hot I notice that the stove itself is incredibly hot, like hurts your face sitting in the chair next too it. And the flame is huge, it was alarming the first time I saw it that high.

Also at extream temps the heat distribution in the house is affected. When +30 to - 10, the house will stay within 2 degrees of the set point. At - 30 my house varies by 5 or more.
Your millage will vary depending on home construction, size, layout, ext regarding temps and heat flow.

My temp probe is behind the stove on my wall... 5 feet off of the floor.. It IS above the OAK and possibly may have picked up cold air from it although cold air drops..?
anyway, I switched over to try stove temp this afternoon.. I have always been anti-stove temp since the whole point of a Harman is to take advantage of the Stoves room temp probe feature and,
Always assumed that pellet consumption was higher using stove mode...[this pertains to using Room temp /Auto when weather is not Gonzo cold like this or above 40 degree days when warm ups occur and no changing settings up or down is needed.
we'll see..

I've been running my stove at full throttle all week to keep temps up. Did same thing last year and never had problem.

What do u have ?

I have the same stove and that has never happened to me. When I first got my stove I used to mess around with ALL of the settings especially the feed rate while on stove mode. Now I just set it and forget it on room temp and that's the way I think I'm going to do this pellet thing.

Same thing with the XXV, I scrape twice a day as flame gets lazy and moves forward to the glass

Coldest night so far since I've had the PB105. It's heating 3 floors of 1000 sq feet each. Including an uninsulated basement. Temps outside went to -24 F and the feed rate is fixed at a little more than 5. Stack temp with a magnetic thermometer about 5 feet from the outlet was about 190 degrees. That is on a small portion of single wall vent. The boiler did burn 5 bags in 24 hours. Cellar set at 78 and first floor at 71. This morning the cellar temp was actually 75 because the modine there is only a 17,000 btu unit. The first floor was at 66 because there is no reflective insulation below the radiant PEX. Soon to be fixed. Once the insulation is there I think I can lower the cellar to 55 or so and save some pellets.

P 61a. Almost heating entire 2600 house in single digit temps

Ah, maybe it is the location of the probe. Either that wall is colder than the rest of the room, or as you said, the OAK is affecting it. My OAK is run on the other side of the stove from the probe. Also have the probe 1.5-2 feet away from the wall and stretched away from the stove. If mine was on the wall, the stove would be at full blast all the time, even on room temp, since it is the foundation wall.

this usually points to an air problem, not a pellet feeding too much (I know, rich burn, same same, but in the extreme cold stuff accumulates at the end of the vent pipe run and restricts the combustion air flow, gives the impression of too much pellet feeding, but usually just not enough air). just take a look at the end of the vent pipe to see if stuff is building up....especially if you have any mesh or screen on the end of the pipe.

Tonyray, I would say you had a draft affecting your room sensing probe. Perfectly plausible explanation for what you describe.

That's a good plan....now to convince everyone else??? NOT happening.

yes.. I think that maybe why... I need to move it or use Stove Temp during these sub-freezing times.
