Looks great except for that extremely unsexy thermostat.

Matt you bring up something we were talking about at the supply house, the cost of that thermostat! Retail price on the programmable is $256.45, now most of us won't actually pay that, but it's still ridiculous. I'm looking forward to using this system but I think Schluter might have this whole system overpriced compared to competitors.

Matt, you are correct that thermostat is poor.

Maybe another company makes an alternative that looks good and will speak with your smart phone?.?

So I cant help but wonder just exactly how you would make it completely waterproof as shown in this video

The kerdi band will sit on top of the "studs" as they call them, leaving a gap of simply just mortar in between them. As we all know, mortar is not waterproof. Am I miss something here?

In the picture below, the arrow is pointing at the area of concern.

If that mat holds nuheat cable we'd use miles.

Nuheat is coming out with a wifi thermostat, in April I think.

Ray, I've always accepted that method with Ditra, even though there is nothing close to a two-inch fleece to fleece overlap bonded with thinset mortar, but I've gotta share your concern with the application you show there (post 50). Doesn't compute for some of us.

CX at least with Ditra there are areas that have a complete seal, although small, you at least have a chance at being waterproof.

With the heat mat, there are going to be cavities in between the "studs" (as they call them) that are completely filled with only thinset. In my opinion it is absolutely impossible to achieve Waterproof!!!

Here in Reno, they seem to have changes their waterproofing opinion from the kerdiband, to a full Kerdi coverage, plus kerdiband. That is certainly what they recommended and demonstrated at the seminar.

Edit: above recommendation is in showers and wet areas only. For dry areas that desire waterproofing, the kerdiband is fine.

Well, that made pretty good sense before the edit, Eric.

Why ever would you need waterproofing in a dry area?

And if you did need waterproofing, I think Ray's point still applies.

Nice big fat (and expensive) bead of K-fix would probably seal it up pretty good. "Probably" but not sure if want an area to be "probably" waterproof.

Kerdi over the entire floor? Sounds crazy expensive.

Ray's point is the same point I made to them at surfaces, possibly in part, prompting the last minute change, possibly?

Their demonstration showed a line drain at the entrance of a barrier free shower with the floor pitched in the direction of the door of said shower. Something I would never do, but for those who choose to, waterproofing the whole floor would be a good idea.

"Waterproofing" is not always waterproof.

I mean, dry areas such as bathroom floors might be made somewhat waterproof or water resistant for occasional spills or infrequent plumbing leaks. In such cases the Kerdi-band wall/floor connection would suffice. I don't think they intended the installation to be submerged.
