I recently was without heat, my inspection (very amateur) of the
boiler led me to believe we had a frozen water paper somewhere.
My house has two zones, upstairs and downstairs. Both set to auto,
once I set to manual the heat began working and appears to still be
However, the radiator upstairs has been chirping. It has been about
12 hours since I set to manual. I did promptly set back to auto
seconds after setting to manual and hearing what sounded like hot
water pumped out from the boiler.
Is this something I need to worry about? I have tried bleeding this
radiator and there was a bit of air, but not alot. Do I need to let
it bleed for a long time?
Any help greatly appreciated.

WAs it that cold in the house? It takes a long time for the pipes and

Even if it froze, as long as it didn't crack any water pipes, that's
not a problem, afaik.
Interesting. I don't have hot water heat, but for some reason it
takes 2 or 3 minutes for my oil/forced air furnace to turn on, after I
turn it on. I don't know what it's doing during that time.
But if the upstairs was cold, the heat should have gone on eventually
An electronic radiator? :)
We're talking about hot water heat, right. I had that for 2 years and
it never made any noise. When the radiators needed bleeding, they
were cold but quiet. I guess maybe -- I forget -- there was a bit of
pounding when bleeding the air let water in quickly.
Why did you not want to hear hot water pumped out from the boiler?
BTW, and here I could be wrong, is it called a boiler if it is a "hot
water" system? I thought boilers made steam, but of course
nomenclature is not always perfectly logical.
Until the water comes out. I suppose you could wait a day and try
bleeding it some more, but bleeding is not the goal. A hot radiator is
the goal. Feel the radiator and see if it is hot, or at least warm,
all the way to to the top. Has the room warmed up? I guess that is
the ultimate goal.
