What kind of radiators are in my house, and how do I fix them? They're broke, it's cold, and the radiators are so old I can't find any information about them on Google! Pictures here. [more inside]

Another heating question!

We just moved to another apartment. It turns out this landlord has the furnace set up oddly: usually the filter goes between the burner/blower and the ductwork to the rooms, but here he's put it on the incoming vent before the furnace. Does that make sense?

Generally, my experience with forced air makes me really miss radiators. I don't like the idea of having dust mite poo blown up my nose, for one thing. Is it that radiators are more efficient and/or cheaper than forced air, or is it that gas furnaces seem more "modern"?

Why are radiators (the things connected to your hot water system that heat a room) usually painted white, when white is the worst colour for heat radiation?

Radiatorfilter: I've got steam radiators in my house. Recently, I took them all outside and repainted them, then put new inlet and exhaust valves on them. So far so good, but when I fired up the furnace, I got a godawful racket. I'm used to the occasional clank from years past (and I went to gradeschool in an old building, so clanking doesn't surprise me), but this clanking is persistent and hasn't stopped for 40 minutes. So: how to stop the clanking? (also: anyone know of a good online reference to how the system works, esp. the exhaust valves?)
