The Vigilant properly set up would be a comparable anthracite heater to your Chubbie. There are members on this forum that heat exclusively with the older Vigilant coal units up in the New England states. Search the forum for member Rewinder's posts. Don't let other peoples' negative comments dissuade you from looking for a coal insert for your Vigilant. Experience means a lot but it does not always develop accurate and thorough knowledge because it's tempered by ability.
To burn coal the Vigilant model you have, you will need the coal kit franco b mentioned. I believe they were rated at 45,000 btu with the coal insert. The trick is to properly seal them when it's installed to keep the combustion air from bypassing the firebed. Rewinder posts some good suggestions on this matter. All Vigilants have a thermostatically controlled air inlet, you don't have to touch it once you set it for your desired stovetop temperature. No pipe or barometric damper is required because of the internal bypass system. Some members do use a baro with them with good results but it depends on your chimney's draft. The combination of the thermostatic air inlet and the internal bypass system team up to perform as a damping system to extract the heat from the exhaust and control the rate of combustion simultaneously. I haven't used the old model, my Vigilant is a series "II"(2), model 2310 and is redesigned on the inside from the early models that are distinguished by the fireback with 1977 cast into it. It's designed as a coal stove (bit or anthracite), not a wood or coal burner like yours. The 2310 burns wood fine, just not to current EPA standards. The 2310 has firebrick lining the firebox and will hold nearly 50 lbs of coal and easily burns at 700* for 14-16 hrs. Mine heats my 3,100^2ft house for most of the winter.
