Roughing in for Nuheat radiant in-floor heating

Hi, first post on this forum. I'm planning on doing some renovations to my townhome bit by bit as I have the time and money.

My first order of business is going to be gutting a utility/laundry/bathroom. While the wall is open I will have an electrician come in to install a new panel. My current panel has no room for expansion and has no main breaker which is a pain in the ass at times.

Having the utility room open will give me access to run wires from the panel to areas where I want to install Nuheat underfloor radiant mats.

My question is for the rough-in for the Nuheat mats; Do I have to install a conduit from the thermostat box down to the bottom plate where the wires will go through for the mat? Or can I just fish that wire down without breaking up the drywall?

Thanks!

 

I'd refer to the manufacturer's instructions on the best way to rough-in the wiring.

 

New construction calls for the conduit for both the power cable and another for the T-stat lead. IIRC there was an exception for old work for one or both conduits to be ommitted. Check the instructions.

 

There is no mention of conduit in the instructions. Below is the instructions for the mat system. I also looked at the installation instructions for the cable type system. That system shows running the "cold" cable and thermostat wiring up the wall without a conduit.

Gonna have to break out the code book.

Nuheat: under floor heat for a warm floor.

After page opens you will have to look for and open Nuheat Mat Installation Manual" as they don't allow hotlinking direct to their PDF manuals.
