My Harman P43 after one year almost two seasons. I started burning pellets for the first time last Feb. With little problems and some learning I can say this thing is AWESOME! Warm house and happy family! This stove burns all pellets well and cleans up easy. The biggest clinker was the size of a quarter if that and came off easy. Flame is nice maybe a bit high at times but the warmth is great! I will never go back to gas or oil heat! Thanks to the ppl on this site as well, you helped me truly understand pellet stoves.
