I've read about the Scandinavian or Finnish style fireplaces that have a

a bit of hysteresis to the heating cycle and keep things comfortable.
The only problem is they take a long time before putting out any real
heat. Maybe a fire all day until the mass of masonry gets hot. The
more mass, the longer it will take. Also the more mass, the more even
the heating will be.
Agreed. I don't like heating systems with a large lag factor. I want
instant heat when I want heat, and when things are warm enough, I
don't want the system to keep pumping out heat.

Right. Cast iron isn't worth its hype. Copper/aluminum is the way to go for
homes (cast iron is more rugged for commercial use).

It shouldn't be a problem unless you change the thermostat a few times
daily. And if you do, set the setting on your electronic thermostat to
change the high/low settings an hour ahead, or more or less to suit your
conditions.

If your schedule is erratic, yes, stick to light weight copper/aluminum.
