You boiler will run much less once you do and it will pay for itself

Can't install insulation (at least the "blown in" kind).
I also have original knob-and-tube wiring, and I believe that the
recommendation is that blown-in insulation SHOULD NOT be used with K&T.

There is insulation in the attic -- directly under the shingles!

I had K&T which I removed, but I never insulated before I sold. Could have,
should have.

I had a couple cycle rate thermostats, got rid of them. Now it's strictly
following temperature on forced air.
