Old as the Romans, radiant floor heating is what customers want today! Customer demand has made in-floor radiant heat the fastest growing sector of the home heating market. And no wonder. This healthy, quiet, economical, and clean method of heating--invented in the Roman empire--is now also durable and reliable, thanks to new materials and
advances. This guide from master plumber, longtime contractor, and renowned how-to author R. Dodge Woodson brings plumbing and construction pros (and even savvy do-it-yourselfers) all the details and know-how needed to: understand and explain the advantages of in-floor radiant heating; install, test, and debug embedded and dry
radiant heat systems in new or existing homes; create heating zones for variable temperatures throughout a house; offer hot water heating as part of your system; heat seldom-used areas and provide outdoor ice removal and other add-on amenities; select superior equipment--tubing,
boilers, expansion tanks, pumps, and controls; troubleshoot and repair system problems; avoid common errors and mishaps.
