Wiring An Electric Floor Heating System

Learn how easy it is to add the soothing warmth of heated floors to bathrooms, kitchens, family rooms, or any room in your home for a more comfortable and inviting living space.

Electric floor heating is an affordable luxury that is now gaining popularity among homeowners.

Including floor heating in bathroom, kitchen or family room remodels has been spurred on by the relatively recent introduction of easy-to-install electric systems.

Pictures below show the installation of a WarmlyYours system (Ph 800.875.5285, Web: www.WarmlyYours.com).

STEP 1: CHECK SYSTEM OHM READING
Before installing your floor heating system, you will want to check the Ohm resistance between the two power conductor wires to make sure that no breaks or shorts have occurred that could affect your system’s performance.

Follow manufacturer’s recommendations regarding the proper variance and the frequency of Ohm readings.

STEP 2: ROUGH IN ELECTRICAL WORK

A dedicated circuit is recommended for your system. This recommendation is in accordance with the National Electrical Code (NEC). Local codes may differ, so always consult with a qualified electrician first.
When installing the thermostat, install a 4″ square 2 1/8″ deep electrical box with a single mud ring. Electrical boxes are typically placed 4′ to 5′ off the floor.

For electric floor heating installations that require a floor sensor, the installer should include two pieces of 1/2″ conduit from the electrical box to the base of the wall (see picture below).

STEP 3: ELECTRICAL POWER HOOKUP
Use a licensed and qualified electrician, familiar with local electrical codes, to perform your system’s final electrical hook up.

If you are planning on doing the installation yourself, you will need to check the following before commencing:

1.  Does your local jurisdiction allow a homeowner to complete this type of electrical work.
2.  Check with your insurance provider to ensure that your coverage is not compromised.
3.  Are you required to purchase a homeowner’s electrical permit.
4.  ALWAYS Install according to manufacturer’s specifications.
5.  Have your work inspected.

Electric floor heating is typically connected to the electrical system via a Ground Fault Circuit Interrupter (GFCI). This GFCI feature may be incorporated in the thermostat’s functionality or it can be provided by the electrician, either at the circuit breaker or at the line’s end, near the control device.

The electrical wiring should follow the wiring instruction schematic provided. Multiple heating rolls may be connected in parallel to the same control device.

WarmlyYours has produced a series of videos that guide you through the installation of a radiant floor heating system. Included in these is a video covering the wiring of your electric floor heating system. You can view these videos at: http://www.warmlyyours.com/install/floor-heating/videos/.
