Gas Radiator - Resonator

This beautiful thing is called a resonator - a gas radiator, I guess. I'd love to know if anyone can help me find out what this really is called. The inserts are ceramic on most of them. I happen to have a few of these here in our home, and I will take pictures of those to share later.

Well, we are hitting below the freezing point here in Aberdeen, and I am still without heat. We are now going on week 5, and now have to wait until 2 more weeks because the money I had saved up to get the guy out here to pressure test our gas line, has yet to show up. Now, please keep in mind that I have called other plumbers to do this, but I am still waiting for Santa to bring me my Rolls Royce Silver Phantom.

Major flaw here is that it takes too long for someone to get a hold of you. Bad business, people, bad business.
