To all the posters and the outstanding and knowledgeable answers on this forum thank you for the help selecting, installing and hints for cleaning my Harman P 43 Installed on December 10 2012 and is heating my 1800 square foot colonial with no problem. My wife and I almost bought a larger unit but some on here and also to my surprise the salesman said this unit should be no issue heating what we need. a nice 72 down stairs and also 71 up stairs gets a bit to much so we close the door about two hours before bed time. its also nice to see the wife in a tee shirt in January and not a house coat all winter. thank you for all of the information on here. I new nothing about pellet stoves and still have allot to learn but if anyone logs on here procrastinating to buy one like I was this is the site to surf I spent 3300.00 in oil last year and i still need the boiler for hot water and it was not a bad winter last year but the house was kept at 68 when we were home and 62 away and at night. I marked where my oil was when we fired up the stove and it moved minimal in almost a month. So thank you guys I rely appreciate
you and this site
