I'm glad some folks shared. That's neighborly. During my
year 2003 power cut, one neighbor ran space heaters off a
generator.
I told him that was ineffective use of power.
Offered to wire his furnace, but he refused. You were kind
to offer, and your neighbor was wise to accept.

I never had access to a generator before but after a few hours
it occurred to me that a space heater was the wrong way to go.

My guess is that the pump on a hot water system takes a lot
less power than a space heater.
