How would one go about calculating the "R-value"
to estimate the heat loss. Any useful rules of thumb?

Trying to decide whether to put insulation over the bricks
on inside or outside or both.

Why don't you put a good airtite insert into it and MAKE heat for free?

Only free if you have a wood lot out back, and if your insurance company
doesn't care. If you have to pay for firewood, it is almost always more
expensive heat than gas.
