Lots of people are surprised, but here it is, http://www.junckers.com/?pageid=H3057
. "Thanks to the Junckers Clip System, a floating floor can be installed over the majority of modern underfloor heating systems, such as electric or piped hot water systems fitted within a screeded subfloor, which give an even heat distribution. We can even accommodate underfloor heating systems contained with battens or joists."
Their instructions say "screed" (the UK version of screed, which is apparently called thinset in the US). The electric heat manufacturer says, "self leveling compound". Elsewhere, including one of the contractors, there are suggestions to use thinset.
