A floor warming tile product calls for a megger? I've tested floor wires before for Ohms readings but never a megger test. How does it work and how does it differ from the Ohms test?

You can get an old analog one pretty cheap.

A megohmeter is an insulation tester.
(Simply put, wires don't break down, wire insulation
breaks down, but that is not the point of this post.)

It puts a very high voltage on a wire and measures
the resulting small current. In the case of floor tile,
it sounds like it would be a good test of product and
installation integrity.

It is no big deal for a well-educated electrician.

In the case of floor tiles, it would make sure the
insulation had not lost its integrity -- worth knowing.

Best advice: hire a (good) electrician.

Requesting a megger to test your floor is the next step in the process to letting you know you're screwed. If it is anything like the fiasco I went thru, the next step will be rental of their line fault detection box. This was/is a joke. If you are so lucky as to actually find a break in a wire you can request a repair kit, fix the wire, and replace a couple of tiles. Even if you could do this it - VOIDS the manufacturers warranty!!! I was not able to detect a break and had to replace the entire floor. Good luck.
In their defense ,though, I had the floor and heater (same brand) replaced by a great tile installer and it is working fine still today. It all comes down to the installation.

I've got a TS100 that I rarely use that someone can borrow...

Some of the manufacturers have a device that hooks up to the wires and stays on until thermostat is installed. During construction if anything damages the wire an alarm immediately goes off to let you know that you now have a big headache.

It's called a LoudMouth.
