Anybody have experience with radiant heating?

Thanks, Bruce. Actually it was easy. I watched the gauge until it got to about 15, then shut it off. Later I walked into my bedroom and there was a great deal of brown liquid dripping from the ceiling onto my bed. (Yucky, but not as bad as H_P's latest predicament sounds.)

I had noticed a small amount of leaking earlier from the upstairs radiator. I guess when I added water, it spouted.

On this leaky radiator, the round valve handle has been broken for as long as I can remember and the water comes straight out the top of the valve (right where the handle is supposed to screw on). I was at the store today and was about to buy a new handle, but I think I should buy the whole valve assembly, no? Surely, there are seals inside the valve itself that are bad and it won't help just to screw on a new handle.

Oh, it doesn't leak at all when I shut the valve, though (using a pliers, since the handle doesn't work).

What do you think?
