Ask Uncle Mud: How Warm Does our Rocket Heater Keep Us?

In response to BeeBob's question the Liberator Rocket Heater with our thermal mass bench needs about one banana box of wood scrap and seven hours of firing to keep the 1200 square foot trailer part of our home outside Cleveland Ohio in the mid seventies (F) when it is 10 to 20 degrees (F) outside. The 600 square foot sleeping room addition has it's own rocket heater that we only ever use when it drops below zero. When it gets below about 30 degrees outside like right now we just close off the addition and it will stay about 50 degrees. perfect for sleeping.
