Ok, so during some more test fires and learning, I managed to get my house to about 80 degrees yesterday (oops) - granted it was about 55F outside. Interestingly, I really do see a difference in draft based on outside temps. - the colder the better (duh).
Anyway, I was hunting around for some info on BTU rating and found this page:
https://www.hearth.com/calc/btucalc.html
From this, there is an example that states this:
"In this case, that direct vent fireplace that was 25,000 BTU's and 60% efficient (60% x 25,000=15,000 BTU's out)..."
I had no idea this is how the BTU/efficiency rating worked but it explains a lot.
Based on this, my old insert looks like this:
Low fire - 2400 BTU/hr x 63% efficiency = 1512 BTU
Med fire - 30500 BTU/hr x 48% efficiency = 14640 BTU
High fire - 156000 BTU/hr x 37% efficiency = 57720 BTU
The new one (with less segmented specs) is 65000 BTU and 76% efficiency (probably not directly tied) but if so, I am likely able to squeeze 38000-49400 BTU/hr out of the new stove.
Does this make sense?
Trying to get and idea of how close to/far from my new stoves capability really is from the old one.
