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.

You have to do that anyway, with hydronic heating. However, it still
matters
if you decide that it's too cold and ask for more heat. For homes, cast
iron
has no advantages, some disadvantages (some major, some minor), and is
more
expensive than copper/aluminum. It's got nothing going for it outside of
hype.

OK sure, cast iron is all hype like you say. There is no comfort gained
when using a heating system with a lot more mass.

No. Mass means nothing. All it does is take longer to warm up.

*And* cool off, which means that the temperature changes much more gradually.

Sure, thermodynamics requires things to be symmetrical, that way. ;-)
However, the time ramping up and down are inefficient. Waiting for the ramp
up, your cold. On the way down, you've wasted that heat. Nothing for
nothing.

Perhaps you live someplace where you turn your heat on and off every day.

When we lived in VT we changed it several times a day, four times
automatically and another one or two manually. Here we have heat pumps, so no
fiddling with the thermostat.

Where I live, it's cold enough in the winter that we leave the heating system
on all the time. We *want* those radiators to stay warm.

I like sleeping in a cold house and reasonable during the day (VT house
59night/64day with a boost to 68F in the evening) .
