What rooms are you planning
on installing in-floor electric heating and under what type of surface?

We installed a Sun Touch
electric floor mat beneath a Ditra membrane which is under large format ceramic
tiles, this was before Schluter Ditra-Heat was available. Schluter is the
‘Gold’ standard for wet room waterproofing and large format ceramic tile floor
decoupling. They are ‘It’, that’s all there is to it! No one does more research
or puts more into product development than Schluter, ask at any high-end
kitchen/bathroom fixture & tile store.

Our bathroom was done almost
5-years ago and still looks as good as the day the installer left. I would not
consider doing any wet room with ceramic walls and floors without a full
Schluter waterproof membrane system – and neither would my wife!

As with anything else
installation is everything; choose a Schluter accredited specialist!

BTW: MUCH of our Schluter installer’s
business is redoing bathrooms less then 5-years old that were done without Schluter costing $50k to $80k! I
KNOW this is true because he was working right in our home when he would be getting
these calls with people sending him pics of their disasters by e-mail to his
smart phone. I heard the conversations and saw the pictures. You can’t imagine
their shock when they heard their projects could not be saved and that they’d
have to start over - from scratch!

I love quietly asking
people, after they rave about their projects, “Tell me, if you had to do it all
over again, what would you do differently?” That’s when the truth comes out.

In our case, almost 5-years
later the answer is still, “Nothing”!

Thank you for your help. This is for a master bathroom. Porcelain tile will be laid over it.

The FlexSnap system works fantastic with the Green Cable Flextherm sells. It's the only system that's strong enough to replace the second plywood when installing tiles (an uncoupling membrane can't do that). Flextherm also sales a Green Cable XL version that is built to fit in membranes such as Schluters and also the Prodesso uncoupling membrane that's sold by Prosol in most floor covering stores.

My understanding is Schluter Ditra heating has two parallel wires so if one goes bad, there is a back up. Does Flextherm do this?

I think you may be
misunderstand the term, “Twisted pair heating cable”, if this is what you’re
referring to. The ‘pair’ is not referring to a redundant cable in case of
failure. It refers to a method of cable construction that 1-pair of wires are
twisted, or wound in such a fashion the electromagnetic field (EMF) ‘generated’ by each wire cancels out
the other wire’s EMF. This is done because we are all concerned about our
exposure to Electro Magnetic Radiation, which is all around us, by the way.
This method greatly attenuates this type of radiation that would otherwise
emanate from these wires.

Most approved in-floor heating
cables are now constructed this way. Just look for some blurb about ‘No EMF’.
Do not install anything that does not
use this technology!

If this is what you were
referring to, it’s certainly not a concern, particularly with this type of
cable construction (No EMF), unless you’re planning to sleep on your heated floor for
the next 20-years as if it were a heated blanket.

Even then, it might not be a
concern.
