I came into possession of a radiator that doesn't have a bleeder. What
the radiator basically is, is a continuous tube twisted back and forth
like a snake.
Now, when I install this radiator, it'll have air trapped inside it.
When I turn it on, the air will start traveling through my hot water system.
Where will it end up? Will it end up spread around other radiators that
do have bleeders or there is another mechanism (e.g. at the boiler) for
the excess air to escape?
Many thanks in advance,
You may have a bleeder at the boiler. It is also possible to do some manual
bleeding too, at the drain valve if one is on the return line. When I had m
system open, it was the same situation. I took a bucket to the valve and
cracked it open so it was a very tiny steam. When the circulator pushed the
air by, I could hear it and opened the valve and got most of the air out.
Over a few days the bleeder took care of the rest.
You probably will just end up with trapped air in the radiator and no
good heat. I would not want or have a radiator without an air bleeder,
to much of a headache and you are now praying it might be ok someday.
I had at least a half-dozen HVAC guys tell me that my baseboard
radiators had no bleeder valves and that the only way to get air out
of the system was to drain and refill it. Even did it a couple of
times, with me standing there saying "But the water you're adding has
air in it too. How's this gonna be any better?"
Finally one guy pointed to a tiny thing near the boiler, said "That's
an automatic bleeder, oh, someone screwed it closed." He opened it a
bit, after the air was bled a bit of water came out, he said "That's
probably why someone closed it, I'll replace it" and now, no problems.
