demand for steam from the other part of the house kept the boiler temperature around 120-140 degrees
You can't make steam at 140F................

Here is some info I found that suggest that they might last up to 20+ years.

Thanks, I'll check it out.

You're right. What I should have said was the boiler temperature never gets the chance to fall below 140f in standby without the burners coming back on. So I didn't see a need to have the thermostat for the radiant heat connected to the boiler to trigger the burners.
With 85F water, it could be run all the time and not overheat the floor.
So do you think 100F is too high?
