The biggest part of the rule that I'm excited about is the fact that all stoves will now have to state their efficiency. No more default 78% and hide away the real numbers. This will help some models and hurt some others but many makers hide the fact that their stoves (and we are talking about very well known brands here cause I've seen the redacted documents) are simply very inefficient. Anyone know of an insert that was recently resigned? Just sayin...
Yep, I though that default chit was bogus! Glad the stove I bought has an actual number! I was suprised at some of the brand names that used the default even! But, I bet there could still be some loop holes that give the brands an in even if they can't meet standards.
Are they just looking at exhaust emissions(particulate)? With some of the stoves I have seen the heat exchangers seem to be sub par and can't figure how they could meet standards in they tighten the grip on overall efficiency.
