Great to hear! I'm glad they came to their senses. The BL do tend to burn quite clean so nobody should know you have a burner in there lol. As far as storage goes, I had noticed last week one day my Heatmaster (very similar in size and design to yours) sat all night with the switch off. I shut it off to load and forgot about it. Water was down to like 70 degrees in the morning but still with a full firebox so I hit the fan and I'll be dipped, it fired back up and did what it had to do, satisfying the shop and house temps in the process. That load of wood lasted me until bedtime easily, even though I had loaded for ~12 hours the night before. So basically the 12 hour load lasted me 24 hours because it was screaming the whole time instead of idling all day like it usually does. I looked into the storage and asked a few questions on Facebook about it, came to the conclusion that to batch burn the most efficiently I'd need somewhere in the neighborhood of 2000 gallons of storage to make a 24 hour go of it in the nasty cold. Basically it'd scream wide open for 6-8 hours to charge the whole system and then nap for the next 16-18 until the next fire. I don't really have the physical space for 2000 gallons of extra storage so I will probably forget about it, but it wouldn't be a terrible idea if you have the space for it. Mlappin has ~400 gallons of storage in his oil burner and had some favorable reviews about it, perhaps he will chime in.
