Hi all, long time lurker, First post. First, a little background. I've heated with wood full time for approximately 45 years and prefer it over all others. In the house that I'm currently in which is a cape cod style built in 1996 approximately 1600 square feet we heated with a lopi m520 circa 1983 for 23 years and now heat with a blaze king ashford 30 and absolutely love it. what's not to love? It gives long burn times always plenty of coals for a quick restart after adding new wood, catalyst stays in the active zone, the house stays a more even consistent heat with way less work, etc. So, onto the question. I'm in the process of adding a 20'x16' addition, mostly glass exept for a 5' section of wall behind the wood stove, 9' to 12' sloped ceiling adjoined to our dining room with a set of french doors. As the wood stove is a main feature of the room, I was torn between a blaze king sirocco 20/30 or a soapstone stove so in the end I opted for a hearthstone castleton. We are far enough along that I've been using the stove for about 6 weeks as I continue to finish the room. It has a pretty fire, burns well, but the adding of wood often drops the cat out of active, then takes to long to return to active and just consumes to much of my time with the shorter burn cycles and restarts. From that little experiment what I miss most and realize what I want most is 12 hour active catalyst times where we have an active cat and plenty of coals for quicker restarts. My main question is will the sirocco 20 give me legit 12 hour active cat and coals or do I need the 30?
 
The 20 should be able to give you 20 hrs of burn time (as the 30 can do 30).
Of course whether that meets your needs depends on how much heat output you need for the room to be comfortable.

So, the stove is capable, but we can't judge whether that would result in a comfortable room from here.

On the other hand, the lowest output of the 20 and 30 boxes is similar, so why not take the 30 and just have a larger fuel tank?
