Hi all, I am in some desparate need of help.

I have rather large radiator that hammers and bangs very loudly when steam starts to heat it. The thing heats up fully and I have no other issues with it.

My problem is that the noise this this produces is really starting to annoy me and im starting to lose sleep in the AM with it because of the temp drop recently and now the boiler calling for heat earlier due to the temp recovery feature on t-stat from night setback.

The unit is about 2'-3" in height. Theres about 30+ columns on this radiator with 6 legs. Two on each end and two in the middle to support the heavy unit.

I just recently put a varivalve on this and had it on full venting because of the size of the unit.

Bang occurs when the unit starts to heat up across the middle sections of the unit.

I am lacking spacing on the top because unit is made to fit in a grove. I think I may have about an inch of headroom for shims.

Are there any other alternatives to rectifying the water hammer? The unit was fine last year until the installation of new valve. Am I venting too fast?

If I shim the end of the radiator, will the center collapse?

Please help or provide any info that may help me! Much appreciated!!!

Thanks in advance. </span>
