I posted about this last winter too. Ive scoured the 10-cpm threads and I've tried all the different settings mentioned. No venting issues I love the stoves construction and looks and customer support, but there is absolutely no comparison between the temp of the air coming out of it vs the brands I've looked at in the stove shops. I took air temps last year in my thread but it died. I am highly frustrated and while I love our 25pdvc, I wish we had gotten another stove for the basement. Do others relate? Is it all due to the heat exchanger system?
Not happy at all with 10-cpm heat output

Can the 10cpm owners please post your air temps that you are getting from the convection air and include your settings of the feed/combustion air, the bottom 3 buttons ,and if your in pellet or corn mode

I burned Green Supremes last year and FSU this year. The output temps with the FSU are running about 50 - 60 degrees hotter at 9 - 9 setting. I run the bottom three buttons at 1 - 4 - 3 to increase the pot stirrer speed. If you're burning the GS pellets, that may be your problem. Try increasing the pot stirrer speed, although that is a no no.
I tried increasing stirrer speed last winter and it seemed to help but i went back to pellet mode. Why is that a no no?
I've taken a few temp readings on my stove while running, in various states of cleanliness. If I'm burning Somersets, with a setting of 8-9, and the bottom buttons at 2-5-1, the convection air temps are generally around 220, although I've seen as high as 250 before. I'm using a meat thermometer inserted into one of the vent openings, taking care not to touch any metal parts.
If you are comparing convection temps, make sure to also consider the CFM ratings. 250 CFM will cool the air more than 160 CFM.
Is it heating your house ok? My stove heats my 2400+ sq ft house pretty well, although it struggles in very cold or very windy weather.

from what i've read, basement installs can be tricky. some folks have good success. but many more (it seems from reading here) have difficulty with basement installs.
Yes I know. My thread last year involved that discussion. Whether or not it heats to my liking doesn't matter at this point. To me. Even if it did, I wouldn't want to have to burn substantially more pellets relative to another stove

Here's my thread from last year. Measuring an inch from the vent opening, igot 185 degrees on 9/9 and 3-5-1 with somersets

i'm not familiar with that stove. but today i measured my stove's air temp for the first time.
i just changed pellets and got curious.
got an oven thermometer out of the kitchen. not sure of it's accuracy, but i got over 250 on high(not touching the metal) w/ 220 cfm quad convection blower & the crabbe pellets. and the heatilator has a non tube flat plate "exchanger" .
could the convection cfm when you measured have anything to do with it?

Are the basement walls insulated and finished or are you dumping your heated air into a concrete, field stone, or granite wall?
Yes, but my reading was taken inside the vent opening. You're reading on the outside. Cheat and stick the thermometer in the vent like I did
If you basement isn't insulated, you're gonna lose that battle everytime. The other thing to consider is your venting. What size pipe, and what's the configuration?
I'm aware of the uphill battle for basements with no insulation. I want to focus specifically on air temp coming out of the 10-Cpm stoves out there...and any comparable stoves for that matter. If you read my thread from last year, it ended up going off on a tangent so I want to stay more on topic this time.
Air temp coming out of a stove is equal to the air temp going in plus the delta-t from the heat exchanger, you have to measure the same things the same way or you are fighting a headwind.
The delta-t you'll get depends upon how well you have cleaned your stove compared to the other party, exactly what the fuel load is in pounds burned and the pellet being burned and how much of the heat produced you are sending up your flue compared to the other person's system..
Good luck with that.
Yes it's complicated and I won't take it that far. But I hope some folks will post some numbers anyway as I feel there are substantial "felt" differences between my stove and the stoves of others despite the fact it isn't apples to apples exactly. The air going into my stove was 40 to 48 degrees when I got those readings last year. When I went to the Hartman and enviro shop I couldn't hold my hand in front of them, nor my friends regency green fire. Maybe the air going in was 20 or 30 degrees warmer...but that's not much
I have a feeling you're going to be disappointed, if that's the case. My Englander has been good to me, and has saved me hundreds of dollars. I'm sure that a comparable Harman would certainly produce hotter temps, and hopefully from less pellets. BUT, I wouldn't even try to compare the two. Would you compare a Cadillac to a Chevy? I wouldn't expect a Englander to put out the same heat as a Harman. If it did, why would anyone pay the premium for the Harman?
I don't disagree..just don't see many willing to comment on that so at the very least I want to compare my temps with those of others. At this point it can be chalked up to the heat exchanger it seems...box vs tubes. I appreciate your input and temp info mithesaint's and I'm hoping ill see the same from the other 10cpm owners on here...there are a few.
I have been runnimg my CPM for 4 seasons now as a primary heat source, I have yet to use a secondary heat source. My stove temps have been taken with an IR gun. The burn pot can, on cold high burn days, reach 650 degrees. The ir temp at the blower vent is always 350 degrees plus. 4 years now with my cpm. Wouldn't trade it in at all. As with any stove, air to fuel ratio and clean intake and exhaust.

That's a lot of coin just for a slightly prettier stove. My 10-cpm is pretty decent looking.
I agree...I love the stove...just wanna make sure i'm getting all the heat out of it that the other owners are
