Another tin ceiling site. The following links may not have specific restoration value, but are useful none the less. Some good articles, and of course a long list of links - some dubious, some broken, some useful. Radiant underfloor heating. It's a good efficient way to heat your home, and in the case of older homes, may be the only effective way to heat it without tearing the whole place apart.
Installation is minimal.
Something to consider. The things on this sight are not antiques themselves, but at least some of them are very good reproductions. This site is really a mass market publication, but it is useful for it's broad range of topics and for its browseability. Surfing the site is a little like walking through Home Depot. You may not find the fixture you want, but looking carefully at all the different things is an enlightening experience.
