Upgrading to a modern stove is a remarkable difference over old leaky stoves. I am fortunate enough to be able to give a direct comparison of 3 using wood from the same source.
1) - Old, drafty, poorly designed air control and the rope gasket around the door is knackered. It is nearly impossible to get a steady burn - it either blasts through wood or limps along because the draft circumvents the flame and goes directly up the chimney. They draft in the room is considerable.
2) - Large and modern with a well designed secondary air inlet that preheats, and a primary source of pre-heated bottom air. Air flow regulation is easy and the fire can be maintained over longer periods.
3) - Smaller and modern. It has good air control as well, but a smaller burn box. It needs a bit more management over the day because it cannot take such large logs as number 2).
Stove 1 is the one in my living room. I estimate that it burns through about 30 to 50% more fuel in an evening than either of the other two stoves, and at the same time doesn't do as good a job at heating the room. Many people would consider it adequate, but with the side by side comparison I can really see the inadequacies and am actively looking for a better stove.
Many people on this forum would also advocate a thermal mass rocket stove. It isn't right for me for various reasons at present, but that would be my ideal at some point in the future.
