Radiant floor heating remodel
Hello all,
I'm currently remodeling our 2nd floor master bathroom. The demo is basically complete and I need some help with radiant floor heating. I have run a dedicated 20 amp circuit for the floor mat heating.Down the road, I plan on remodeling our guest bathroom as well and I wanted to know if I can put both of them on 1 x 20 amp circuit. Running wires to the attic isn't the easiest
The master bathroom will be roughly 45 sq feet of a product like sun touch warm wire. The guest bathroom will be about 35 sq feet.
Thanks

According to the website, 100 sq feet draws 10.0 amps. I will be well under that so I'm thinking it will be okay. I just wanted to make sure there were no contraindications of the NEC to wire the two mats in series, in two different locations.

That would be two mats in parallel. Yes.... you can put them on the same circuit. Be careful when it comes to installation as you don't want the thermostat box stuffed with wiring. Setting a box in the attic with two stubs would be a good idea.

Also, consider 240V model if available. Pulls less current and will be able to put more loads later if needed.
And with radiant heat mat, too much is worse than too little. I found that out hard few years ago in a large bathroom remodel. I had about 10 sq ft too much and you cannot just cut remaining mat. Had hard time finding place to fit extra mat.

That’s why I planned on going with the warmwire system that you can make yourself. They come with a spool of wire that you weave into the appropriate pattern you want. Having extra scares the crap out of me!
