I don't know what system you use but most systems I installed have recommended set point no higher than 85*.

The Ditra Heat Thermostat has a setting that monitors the current temperature and calculates when the system should turn on so that it will achieve the correct temperature previously set for a specific time. You just need to show your client how to do this.

Ex: You want your floor to be 80F at 7:am and is been a really cold night the system will calculate exactly when it should turn on so that it will be a warm 80 at exactly 7AM

Re: Ditra "Heat"


I've installed cable systems in the past having to go with the self leveling system. Once under tile and once under finished concrete in a loft. Can someone PM me what I should be charging a sq ft for a install of Ditra under tile? Thanks

Re: Ditra "Heat"


Install docs say 2x2 as a minimum tile size. Has anyone run into this, or disobeyed? I have a client leaning towards small tiles. Should I go with a mat system and self leveler instead?

Re: Ditra "Heat"


If you look at the mat itself, you'll notice it forms little individual piers under the tile with an air space between them. Imagine a point load on the edge of a tile which happens to be over an air space... It compresses, grout cracks, tile de-bonds from Ditra. Unlikely? Probably. But there's bound to be many of these weak spots on a Ditra floor covered in tiny mosaics. I wouldnt risk it.

I've done plenty using a NuHeat mat covered with SLC instead.

We just installed the dirt heat mat but we used Nuheat cable system. Works good. Was nice sitting on the floor messing with the vanity with the heat on...

Re: Ditra "Heat"


I just installed Ditra Heat with a NuHeat cable system, and NuHeat wifi thermostat. Awesome. Ditra made running the cable so easy and quick. HO keeps the floor at 80.

That's the second cable system I've installed, but first with Ditra. No complaints.

Re: Ditra "Heat"


Why Nuheat cable over Ditra heat mats?

Re: Ditra "Heat"


Golden, this bathroom was for my brother.

I actually had the cable left over from a error on a previous install. I sent a helper to pick up a cable for 25 sq ft that the sales guy had set aside for me. When he got to Billows, the guy realized he only had a cable for 50 sq ft, and gave him that at the same price. Way to big. The whole bathroom was only 5x8. I bought the 25 sq ft somewhere else, and intended to return the 50. Never happened.

On these two bathrooms, it was just quicker to buy the cable as I would need custom mats and I think they take two weeks. I can set the Ditra one day and cable and tile the next. I believe an experienced tile setter can even do everything the same day. I'm not that guy.

I bid a fairly large area before that I was going to use the mats. But, never happened. It was for some show dogs.

I'm not opposed to the mats, just haven't used them.

Re: Ditra "Heat"


Just an FYI... you can get some premade NuHeat mats rather quickly... I've ordered up their 2'x10' mats just to run a stripe of warmth in front of a vanity and toilet. I think that size was about $300 for the mat.

Re: Ditra "Heat"


I've been looking at those premade mats. How did you like them? Seem very easy to install. I've done very little electric radiant. Mostly hydronic where it was the heat sourcefor the entire house (or garage, airplane hanger)
