.....I believe the flooring is the new polyurethane/wood chip board called "Ameri-tech"-which is good for a flooring material and has a 50 year warranty- then there is a insulation barrier of at least a R-10 and then the heating tubing covered with a laytex cement covered with the ceramic tile.....or this is how it should be installed....somewhat flexible....yet very heavy duty usage-almost commercial.....the cement and tile form a heat sink that holds heat evenly throughout the coach-no cold areas...the closer you are to the floor the warmer you get-No cold feet and No drafts...ideal for small kids and us old cold footed farts....you could use an outside heating source if it was available...maybe a small wood stove and a circulation pump or even someones hot water form their house-'course they are going to be pizzed off when they get the bill....there are several different liquid media for heating but I'd use plain old 50/50 antifreeze solution-which is available from any Walmart-gaas station or even Kroger stores.....geof
