All is well here.

I just had to chime in when hand fired stoves are being so viciously attacked... 65% Non-sense. Everyone knows that stokers are inefficient and bad because they waste coal when the flare up the fan. :P

The question of a stoves sufficiency to heat a home is not being questioned here (since that fact is already known for all of those using the stoves). The matter of comparison to whole house heating furnaces and boilers is not at question here either. The question is merely how are they being rated for BTU's (which means BTU's per hour of input).

I appreciate the concept that if it heats your home its BTU's are sufficient (as common logic dictates that), but that in itself does not answer the question of how the manufacturers settle upon a BTU rating for their hand fired stoves. What methods do they employ (if any)?

I think it's simply about sales.. Nothing more nothing less and as I said it's a comparison for owners of a furnace....

Thanks Stan! If that is so, then the BTU numbers for hand fired stoves are mostly hype. If that is the case, then it is truly sad.

To get the 70000+ "rating" from my Harmon you'd have to fill in 4 times a day burning a full load of 50 pounds fresh each time. Or you could just get a mark 3 and fill it 3 times a day... Why would you not get the mark 3 if you need more btu's on average. If you need a ton of heat the actual 70000 btu's you'd just get the SF250 and fill it again 2 times a day. I believe the "load rating" or the amount of fresh coal that fits in the hopper or on grates is the part that matters for a coal stove. It can burn this load in 12 hours and have real meaning for the home owner. It would mean the house will be warm after sleeping in on Sunday morning. 8-)

The rest is crap that don't matter. IMHO

So i take it that we should not question how the manufacturers come up with their BTU rankings? Why not?

SUGGESTION Larry---call a few manufacturers & see what THEY can tell you--right from the horses mouth--REMEMBER---I said MANUFACTURERS---NOT dealers

None among them make hand fired stoves to my knowledge. I'm leaving Doug out of this (unless he voluntarily chimes in).

Larry, any of the stoves you are considering will produce enough heat to chase you out if the room it is installed in. I think you should pick one that your wife finds asthetically pleasing and be done with it.

Notice no manufactures are touching this thread with a 10 foot pole ;) I don't mind touching....so here you go

The simple fact is there is no governing body that sets and enforces an industry standard. As a result, some manufacturers manipulate and inflate BTU numbers to entice buyers to their products. One person's conclusion could be vastly different than another persons... in recent years this dilemma is much worst than back in the day when things were done in a very similar fashion and method as your all tossing back and forth (Do not fool yourself into thinking these companies but that much effort into pinpointing BTU ratings these days).

PostBy: lsayre On: Fri Sep 20, 2013 12:23 pm

Thank you kindly Doug! That pretty much seals it. BTU ratings are whatever the manufacturer determines by whatever method the manufacturer chooses, right or wrong, real or fabricated, since industry wide standardized testing as such does not exist.

In such an environment, methods such as the DS Machine method of using 400 times the grate area in square inches at least show a high level of consistency, though they may not have any real world validity.

I see now why you have mentioned that the BTU ratings for the Crane stoves appear very conservative by today’s (ahem) standards.
