I'm trying to decide which pellet stove to get . This will be my first stove. I've narrowed it down to the Harman Absolute 63 or the P68. I have a multi-story solid brick house with no insulation and some drafty windows. I'm trying to supplement my existing heating system (gas forced air). I like the P68 for the workhorse that it is and ease of making repairs myself. I love the look of the 63's self diagnostics, and whisper mode. If anyone has some insight to either or both, I could use the adivise. Thank you in advance!
