Just an update on my Harman XXV:
Saturday morning of New Year's weekend, Distribution Blower shit the bed.
Was heading to Binghamton, NY anyway and Kitchen Hearth & Home, on Front Street was on route. Didn't buy my stove there, but they've always had the parts I needed. Will buy my next stove there if I need one. Great folks.
Got my other stuff done, and pulled in just as they opened at 9AM. Pulled out with new Distribution blower, and also grabbed a Combustion Blower while there as a spare.
The Distribution blower was $274, and Combustion blower was ~$140 with impellor/fan.
My stove has had ~80 tons of pellets through it - 2nd time I've replaced Combustion Blower. I think I'm on 3rd Combustion Blower, but one replacement was a PM item.
I did have a circuit board go ($200), replaced a vacuum switch and auger motor as a PM couple years ago. Auger itself is original.
I think all-in, I'm ~$100/year in parts, but the stove is 14 years old and running great. Obviously, I do all my own service work/maintenance, etc., so I don't pay someone to clean my stove/vent each year (~$100), so I'm okay with this.
The stove paid for itself in the first 2 years, and is our primary heat source now, over fuel oil.
