I don't think its the pellets....they may not ne the best but they are good enough with your size stove.
If it maintained 70, then the stat was probably not calling for heat the entire night... and the stove wasn't running the entire time.set the stat to 70 and it maintained 70 all night. It burned a little over one bag in 14 hrs
Last night we had our coldest night, -2 F. I ran the stove on heat level 5 and set the thermostat at 72 in High/Low mode. This morning the house was 60! Even the room the stove sits in was only 62. My house is only 1600 sq feet and the room the stove is in is approx 19x12. I miss my old cheep wood stove. It was only rated at 45000 BTU's and I could keep it 75-80 in the living room and 70 through out the rest of the house. I've never been so upset and disappointed with a $3,000.00+ investment!! Not sure if I just have a dud or I purchased the wrong stove.
Thanks for any insight

Nick,
I am having the same problems with my Harman P35i. I have a ranch house approx. 2000 sq feet. The room the stove sits in is 18' X 15'. I had the stove installed the first week of November. The first really cold windy night the stove could barely keep the room it was located in at 68/70 degress. That was with the stove turned to 85 degrees and the feed set to 5. I even called the installers back to my house becasue I thought the stove was not working properly. The installers said the stove was fine and that they were shocked it couldn't bring the room temperature up higher. This is the stove they recommended and now are thinking it might be undersized. I wish I never bought it. I am into for $4200! The installers stated they were going to check with Harman to see about a "dip" switch setting?.... If they tweak my stove and get it to run hotter I will post results.
Feeling your pain,
David
Nick,
I just had an on-line chat with someone and he believes that your hopper block off plate is set two low due to the 12 instead of less than 9 hour empty time.
Couple that with some heat possibly going up the flue that shouldn't be and you likely have enough horses to heat that place.
This also means that your setup mag/dwyer readings are incorrect as the stove was not burning at its highest rate.
Windy days will find all of the leaks in your house's envelope including the one just above your stove. If that insert isn't properly blocked off and insulated it will act exactly like the chimney it is, in addition it is possible that you are heating up the brickwork of that hearth the stove is inserted into.
Air infiltration is the number one heat loss in most otherwise insulated houses. If your home does well on cold none windy days air sealing will make a huge difference.
On a really windy day with certain attic ventilation it is even possible for any fiberglass insulation to be raised a bit in the attic causing cold air to wash the ceiling and negate the insulation value of what the depth would lead one to believe..
Followed by windows if there is a large expanse of windows. R-2 maybe with some of the newer quad pane units R-4. For the window area itself.
Next comes any concrete walls above ground level. Concrete is a lousy insulator and that foundation above ground level is about R-6 if you are lucky. Below ground is better due to the increased (yes, that is no mistake) exterior temperatures.
SmokeyThe Bear,
Thanks for your reply and insight. The house has New Window and doors and the exterior is made of Brink and stone. The floors are hardowwd through-out the home. The installer checked my house from top to bottom including my attic and said the insultion was OK (not bad, not great) and rated my home for .75 btu per square ft. I like to hear a little more about the stove being "properly blocked off and insulated".
Thanks,
David
