However, the Quakers are MUCH larger stoves than the Glenwoods of the same number. I can only assume the reason being that the Quakers have a deeper fire pot than the Glenwoods and a longer/taller cylinder as well.
Yes, different companies had unique depths of firepots to go along with the diameter. Deeper fire pots are much better than shallow ones. In choosing a stove you need to consider the its total coal capacity to get one that can provide enough heat for the area heated during the coldest weather.
The fire pot diameter is a pretty good rule of thumb to determine that. A stove with a twelve inch fire pot can hold around 40-45 pounds of coal for example.
Germer Radiant Homes, have models with fire pots of up to 24 inches. I have seen one with a 22 inch fire pot. Its BTU rating would be well in excess of 100,000 BTUS per hour running at a normal capacity.
I don't know how accurate this is and I have no basis for it, but; I always would think that for every pound of coal you would get 1,000 BTUS per hour at normal operating temps. So a stove that holds 40 pounds of coal can, AT LEAST produce 40,000 BTUS per hour. I think that is pretty conservative guess. I have nothing to back that up so I'm wondering if that is way off base or is a good way to estimate.
