buffalo ny: climate may freeze water pipes if you reduce basement's
waste heat. we have an anti-freeze thermostat running electric water
pipe heaters in winter with the old boiler gone.

All,

Thanks for the info. I'll ask a heating pro about it, but I do have
the concern that they have the incentives to want to do work whether
needed or not. Or maybe I'll just insulate it.

I do have a hot water system with modern oil fired furnace with
programmable thermostat. My mentioning steam is based on my guess that
maybe it was steam in the past and then converted. I think that some
peoples guess that it was a gravity fed system may be correct.
