Wow --- terrific post, peakbagger, thank you.
I have a 31 year old uncertified wood stove I installed in my house in 1987, and have always been happy with it. Unfortunately, reading threads on this board seems to extent stove envy in me ----is this a communicable disease?
I've always been a frugal guy, and found cheap and found cheap deals on washers, dryers ranges and such from "distressed" sellers who were moving and HAD to get rid of useful appliances ----right away. That's a variety of what you seem to be describing with the market for wood stoves.
As a retired furnace and gas fireplace repairman, I'm capable of making inspections on such appliances, but woodstoves are a lot different. The skill to be able to uncover and recognize the damage from overfiring or other issues seems pretty specific to wood stoves.
I've been looking at what's been offered on Craigslist and then Googled the particular model to identify the specifications of the stove in detail and the comments and opinions about the stove that are often on the internet ----often from this very web site.
One issue I have is that I burn scrap wood that is abundant in my area at zero cost. All I need to do is throw it in my van and cut it to length with a circular saw or table saw. That seems to be discouraged by manufacturer's of catalytic stoves in particular, as perhaps resulting in damage to the catalyst by chemicals that may be in scrap wood.
If that's the case, perhaps continuing to use my old uncertified wood stove is a good strategy.
At age 68, I figure I have 5-10 years before it's likely that I will retire from wood burning and sell off my house. From your comments, it seems that there might be good reason for pulling the wood stove out rather than selling the house with it in it. With 30-40 years of use on an old stove, I could certainly do that without a qualm.
Thanks for your comments!
