Ron (and rest of the gang) .:| [The Public Television Show 'This Old House' put some in a .:| $$$$$$$ home .:| in Massachusetts a while back, for example.] .:| .:| I have not been actively following the 'green building technology' .:| scene. .:| It's a very very neat idea, but are these underfloor .:| heating boogers .:| actually an affordable option for the average person yet? Absolutely ... given that we're talking about the same thing ;) Back home (Iceland for those that've forgotten ;) we mostly build concrete houses and use hot water for heating. And a couple of years ago, as my parents decided to renovate their kitchen / dining room area, they had water pipes inserted into the concrete. They have the warmest cheramic tiles there are. And while they're not poor, they're not filthy rich either, so I'd guess they're about average :) cheers, elfur the 'fake' norwegian one  And, actually here as well. The flat I live in here in Norway has floor heating as well. But oak parket, not cheramic tiles.  This was not a good time to live "downstairs", btw, with the workers breaking up lines in the concrete floor above.
