My radiator sounds like a dryer with a pair of sneakers in it.

[GirlinContempt]

Or, a handful of quarters, I can't decide.
Possibly both.

It's got that rhythmic sound of change being flung around in a dryer, but also the occasional thumbpathump of something too heavy

1. Probably a ghost.

[GirlinContempt]

2. The ghost of quarters past. It's deff. not nickles. The sound is too 'ringing' for that,

5. You're gonna need an old priest and a young priest...

Godspeed.

6. Can't I just hurl some holey change?

3. radiator has air in it and needs to be bled???

some experience in living in a place with a radiator
l o n g a g o

hell of a racket
janitor got the air out and it quieted down.
heated better too.

4. I want NO heat.

Heat is evil. This place is sweltering :(

7. Surround it in a space blanket (mylar)

and channel the heat up and out the window. Maybe a blanket around the radiator would muffle the sound some, too.

8. Hmmm, that`s possible!

9. Actually what it has is water in it

the steam hits the water and the water flashes into steam, creating the noise. Make sure the radiator hand valve is fully open and replace the air vent. That should solve the problem

11. Air... vent?

I don't wanna open it, then the heat will come out more :(

14. Doesn't it depend on if it's a hot water system or steam system?

Ours is hot water and it will get noisy when air gets into the system. We bleed the air out until water begins to come out.

13. We have to bleed the air out of ours occasionally.

There's a little key for our radiators. I've never had it get really loud though, just annoying.

10. So far today is quieter.

12. Did you offer the radiator demon an animal sacrifice or something?

[GirlinContempt]

15. I left a peice of cheesecake on it overnight
