Not sure I believe the EPA

So I was looking at the EPA list of approved stoves for Sept 2011: (broken link removed to http://www.epa.gov/Compliance/resources/publications/monitoring/caa/woodstoves/certifiedwood.pdf)

The Jotul F602CB is listed as 3.4 g/hr of particulate which I believe, but the btus are rated 11,998 to 47,713! No WAY did that make almost 48k btu! If it does, I'm impressed. Jotul only rates it for 28,000 btu and from what I understood normally the EPA tests fall well under what the manufacturer's rating is.

If the 602 can indeed put out 48k btu, it would be great even for my house!

Could be a typo. FWIW, we heated the place with the older 602. It could cover us down to about 30F outside. But the colder it got the more you became like a locomotive fireman, stoking the stove constantly.

I believe the EPA ranks it within it's normal cycle and puts out a max rating. So at max under their conditions, 48k btus. They don't say how long it can pump out that volume.

FYI, My lopi says it can do 73k BTUs/hour: (broken link removed to http://www.lopistoves.com/productuide/detail.aspx?id=303#Specs)

It does not

How big is your house?

Yeah, I don't think it's a normal cycle/max rating because that would mean the Englander 30 averages 11,950 btus and has a max of 28,337. Highly unlikely.

Also, the 17-VL has TWO listings. One is 11,875 - 19,238 and the other is 12,791 - 43,520! That's quite a discrepancy!

Also, the EPA lists hearth.com as a resource! Neat!

those numbers usually have little to do with "real world" applications. The EPA testing methods are strange to say the least.
