Ok, I've asked two of the local HVAC companies
in the area I'm moving into and gotten two
conflicting answers... So please be gentle
I'm moving into a house in Michigan which has
a natural gas fired baseboard hot water heating system.
It was built without much in the way of thought
regarding energy conservation. To put it mildly.
There are separate piping loops for various sections,
with levered shut-off valves on them. All are
Anyway, I asked the HVAC folk if I could, say, shut
off the valves to the garage area and what this would
do in regards to the circulating pump.
(There's enough heat leakage that I don't have
to worry about the pipes freezing. At least
until I do a lot more retro-insulating).
One said it would make the pump work harder
and wear it out sooner; the other said it
would be ok and might even save a bit
(In the long run I'll have them do proper
zoning and controls, and get a new higher
efficiency furnace, etc., etc., but all
that's got to wait until I find out the
truth behidn the Kennedy assasination.)
Seriously, for now I'm mostly concerned
about the pump issue, and given that I
got two different answers, I'm appealing
to the experts.
