Welcome to the forum Layland.
Leisure Line, Keystoker, Alaska, and Harman.
These are some of the manufacturers that make nice stokers that would heat your space nicely. I would suggest doing some reading here on the forum in this section of the forum and then maybe make a list of requirements like price, hopper size , ash pan size whether you will heat domestic hot water with coal as well, whether you can put a thermostat upstairs to make sure the space you are heating is warm enough, whether you want to put air into ductwork to help distribute it, etc. Also you might do a search on threads about boilers as already suggested to see if maybe that would be better than a stove. In other words if you already have baseboard Hydronic heat then why not use it to get the most even heat, in the long run that will be the most comfortable and even heat and can provide for your domestic HW as well. Such a system could be connected in parallel with your existing system to make sure you have a back up.
I would also check in with the local stove stores and see what they have to say and how friendly/helpful they are (or not). As I said some readin on the forum will help there are already similar threads that can provide some insight and will help you ask the right questions.
Keep us posted on your search and as you gain knowledge ask some more questions.
