I would need to get this right the first time or you guys would be hearing about my funeral.
Lets not hear about your funeral, just stay on the manly side
. Don't know how a larger stoker would do but look at it this way if it is 72degrees with a stoker or 72degrees with a hand fed, the room with a hand fed is going to feel more comfortable. Been there done that and went back to a hand fed. that constant heat of the radiant hand fed just warms up everything and then the objects give off the heat. The stoker heats some air blows it around then the room cools and it goes through the cycle again, the objects never seem to get warm and you have that less comfortable feel.
When I had my stoker I used the same amount of coal. It takes a certain amount of btus to warm a given area, so if the efficency ratings are the same useage should be, however, certain ways of obtaining those btus seem to be more comfortable
Good luck on which ever way you go, Eric
