Well, Don't laugh ya all! A bud bought the 25 IP and felt the same. Not enough heat out the convection as to what the old stove he had. He also felt he was burning a bit more pellets ta boot. We fiddled with the settings and yadda yadda yadda. Seemed we were getting nowhere, Not getting good convection and passed too much out the vent no matter what. Only way to get the temp up was to do the no-no of running the fan below the heat level setting.
So, I took the lid off and the front grill out. Measured the top of the box and did some figuring. Wound up getting some tee channel extruded aluminum from a local place. Cut them to length and laid them on top of the box to help pull some heat(wick-heat sink-what every). No fasterns were used as I didn't want to risk a leak! With everything the same we pulled an extra 25ºF out of the convection air. I only could get 1x1-1/2, might a squeezed a bit more with a large profile?

I don't like a box heat exchanger, I want the most area I can possib
ly get to extract the most possible. To me the stoves with the box like the cab series and these. Are not going to be as efficient as the tube or accordion type heat exchangers. IMHO the more area offered to convect heat has to improve the overall efficiency.
Carry on!
