If I decide to leave my oil furnace on, set at 43 degrees, to heat the house while it is vacant during the NH winter, I've been told that I should also shut down the power to the water well and pump and drain the pipes. How does this affect the hot water baseboard heating?

Is the baseboard heating a closed water system..... Will it work if the rest of the house has no water because it has been turned off?

I don't want to "winterize" the house and let it sit cold for the entire season...could damage wood floors, walls, & foundation.

    it shouldn't

    as long as the system is tight.  Try shutting off the fill valve for a few days and see if your pressure drops.

    Other ideas.....

    To me, 43 is cutting it close.  Doesnt give you much leeway if the system has a problem.  If it were me, I would make sure there is some freeze protection to warn you if the heater shuts off--alarm contacts on the primary control or thermostat.  Also, you should have a low water cut-off also...just in case.
