I noted no one answered....you maybe able to figure this out yourself by measuring the grate area ... see prior thread on subject matter a grate area to BTU ratio is noted.

Others may chime in.

Lbs. Anthracite Burned Per Day & Avg BTU's Per Hour Output

This chart shows the BTU output per pound of coal--so if a stove holds 50 pounds, the heat output is 20,250 BTU's per hour. But there are variable that make it complicated, such as carbon content of the coal, moisture, etc.--and the efficiency of the stove. (How much is lost through the chimney is significant, and varies with things like internal flame-paths built into the stove, leaks, air controls, etc.) But the chart gives a rough way to compare stoves according to how large the coal bed is, length/width/height. If you get coal in bags, it is easy to see how many pounds your stove holds. Mine holds 50 lbs--one 40 lb. bag plus about a quarter of a bag more.

You can control the output, of course, by opening or closing the air intake, and it is not advisable to run a stove at maximum heat for long periods. You can determine how many BTU's you need, based on area, by this chart.

But of course everything depends on your climate, your home insulation, and your preferences (for instance, whether you want cooler at night, or in the back rooms). I want to be snug in the coldest times, so I like either a big heat source, or several sources, such as a gas space heater in addition to the main stove. Here is a nifty idea, but not cheap: a good-sized wood/coal stove in the living area (around 50 lbs of coal), and a wood/coal kitchen stove that has a side-car using gas for the summer.
