All,
I have been a recreational wood burner in a ~30 yo pre-EPA coal insert with no name-plate or emission info (that I bought with the house). It's hooked to an 8" direct connect (that I installed...it was a slammer) on a 25' tall clay-lined interior chimney from 1960. My estimates say it's running at an BTU eff of ~45%, no secondary combustion at all, 2 hour burn times. It might put out 20-25 kBTU/h if you stuff it every 3-4 hours. This is just enough for winter backup, as determined in last year's ice-storm.
The wife and I would like a 'flush mount' insert with an EPA rating, and don't want to drop $4-5k for a new unit with install. I am leaning towards trolling craigslist for used inserts, perhaps for a while, and doing a DIY liner kit. I figure I can do 6" no insulation, or a 5 or 5.5" with insulation. With the interior chimney in good shape, I am ambivalent which option is better.....I favor the no insulation b/c it will be easier to install, but on the other hand with the height, I don't think the downsize to 5.5 or 5 would be a real issue draft-wise.
Local craigslist shows a VC Montpelier Insert with Mead surround, 3 yo, for $1500, versus $2900 MSRP. Figure I would offer $1350 if I decide to pull the trigger. Never craigslisted before.
Looks like a 1.5 cu ft box, EPA rated, fragile refractory on the top, tendency to develop hairline cracks. Rated for ~20-25 kBTU/h sustained output, which is aok.
Any input about how to handle the flue OR the merits of buying a used Montpelier? I figure I could be done for ~$2k all in with the liner kit.
I am not worried about long-term durability....will still be a rec burner, but happier with longer burn times and less shame at smoking out the 2nd biggest metro on the East Coast.
