Got a situation with trying to heat an acrylic shower pan that will be used as a changing table top for my buddy`s handicapped son... (See pic). We are using the Ditra heat system in the rest of the bathroom floor, but Ditra says no to covering the wire with anything that will contain the heat... they say the wire will ultimately burn out without a way to dissipate as it can with a typical floor application. We want to use the acrylic pan instead of tile for many reasons, not the least of which is comfort of his son. We are considering an airspace between the pan and the heat, or louvers in the edge of the pan, with holes in the deck that the pan will be on, to create a `draft`up and through the area to move the heat out of the way... but my friend is worried it might move too much heat away...
Hoping someone has working knowledge of the Ditra system, can give they`re two cents... Yep, I have talked to the local rep of atypical installations and he said that he`d never had this question and there will be warranty issues, but seems open to helping further, but I think it`s on me to bring the ideas...
I appreciate any input you brilliant folks can come up with !! Thanks again, BB
