I would say no. All the thermostat does is call for heat.

You could put a timer on the circulator-- but I doubt that is a good
idea. Why do you want to do this?

I suspect the current setup allows for the most efficient use of
power-- your proposition totally ignores how hot the water is. It
seems to me that water temp is of utmost importance.

It's a wood boiler and I do it that way manually now and it works great.
The problem is that when the fire goes down the circulator runs all the
time unless I shut it off.
