    So last night here in Maine, it was pretty cold (probably a decent amount of heat loss happening).

    For most of the season, I almost always run my Harman Accentra on stove temp - keep it throwing heat to heat the back bedrooms.

    But last night, I didn't feel like the Harman was throwing out enough heat with stove temp. So I cranked up the stove temp dial to 6- didn't feel like it made much of a difference. I took a meat thermometer just to have some sort of indicator and put it in the blower grate and let it sit there for half an hour.

    Then I put the stove on room temp, and the heat output was higher.

    WTH?

    I thought I understood the ins & outs of my Harman, but this threw me for a little bit of a loop

    Maybe the fan speed was higher when it was in room temp. mode. Did you have the fan speed all the way on high when in stove temp. for a fair comparison?

    Absolutely. I had the stove temp on high - same as in room temp.

    I've been heating my house during this recent cold spell in Stove mode as well, and I was aound a 3 heat setting the whole time. I can't imagine heat setting 6.

    Update.

    I pulled the stove and did a full cleaning (when in doubt). I opened the fines box and it was packed full and solidified ( I must have missed it at my last year end cleaning - whoops).

    So cleaned that all out and oiled up the moving parts.

    Now stove temp appears to be better.

    Question, would a full fines box really impact stove temp performance?

    I always refer to my stove as she. We nicknamed her Sparky.
