Stoker-man, I have a question about the EFM WCF-24 produced a while back . I have just determined that the firebox on my EFM WCF-24 has a crack plus a lot of warping. I have decided to replace the unit and not take a chance on getting the crack welded. I got good service from the WCF-24 and would buy that product again (I bought mine in 1992 and used it as the primary heat source for a 2200 sq ft house). However, EFM doesn't make the WCF-24, and I can't quite see using the WCB-24, so I'm probably going to another manufacturer. I talked to someone at EFM today and got good information, but I have a question still: Do you know the gauge of the metal for the firebox?
In looking at wood furnaces, I see warranties of 5 years. Is this industry standard? [I got 17 years from the EFM, should I expect that from a new unit that is warranted for 5 years?]
I also see some wood furnances that are rated at 120,000 BTUs (or more). I believe the WCF-24 was 60,000 BTU and I ran it pretty low much of the day (I'm sure the firebox warping occured during the the other portions of the day!). Any opinion on whether these 120000 BTU units can be run well at a much reduced output? (by 'well', I mean stay lit, produce low cresote, and low smoke).
Thanks for any info.
