How is Nuheat installed?

Installing Nuheat is easy. The electric floor heat mats are ready fit right out of the box and are installed on top of the sub-floor right under the flooring. Whether a standard size (square or rectangular shaped) or custom-made to fit your room (with angles and curves), Nuheat’s electric floor heat mats are ready for any project, whether it’s a new tile floor in the bathroom and kitchen or a laminate wood floor in the family room, you do not need to string out, cut or splice any heating wires to do the job. The heating wires are bonded between two sheets of durable fabric. This allows the tile setter to lay the tile without the worry of moving the heating wires causing cold or hot spots on the floor after the job is completed. A 10′ Power lead comes off one corner and is to be connected to the LOAD side of the Thermostat.

The steps are the same for any room; the only differences are dependent on the type of flooring. This is a summary of instructions; but read the Installation Manual included with your order for complete instructions. And remember to check the resistance readings with your multimeter often.

NEVER connect the Nuheat mat to power until installation is COMPLETE.

Tile, Stone or marble floors Once your subfloor is prepared:

1. Simply apply a layer of thinset (acrylic/Latex modified) with your trowel
2. Place the Nuheat electric floor heat mat into the thinset bed. Nuheat mats can be laid with either side up. Press the Nuheat mat into the fresh thinset bed to ensure full contact and adhesion. Install sensor wire.
3. Apply another layer of thinset on top of the Nuheat
4. Lay your tile, stone or marble
5. Connect the Nuheat mats & the floor heating thermostat (qualified electrician recommended) Allow the thinset to cure (per the thinset mortar manufacturer’s instructions 7-28 days), turn on the system and enjoy your warm tile floors. Nuheat is the easiest electric floor heat system to install.

Floating Laminate, engineered wood floors, Carpet or linoleum Once your subfloor is prepared:

1. Roll out the Nuheat mat on top of the subfloor to test for fit.
2. Simply apply a layer of thinset (acrylic/Latex modified) with your trowel
3. Place the Nuheat electric floor heat mat into the thinset bed. Nuheat mats can be laid with either side up. Press the Nuheat mat into the fresh thinset bed to ensure full contact and adhesion. Install sensor wire.
4. Apply another layer of mortar or self leveling cement on top of the Nuheat mat to completely cover – we recommend 1/4 inch overall
5. Once the Mortar is cured, install the flooring on top. Gradually increase the Temp. on the thermostat over 72 hours, or as recommended by the flooring manufacturer

How long is the low profile Nuheat power lead?

The Cold Lead (aka power lead or cold tail) is 10′ long and can be shortened freely. If you need a LONGER lead it can be extended in 2 ways:

1. Have your electrician install and use a Junction box
2. Purchase a Nuheat Lead Extension Kit Here and extend the lead an additional 10 Feet:  110V Extension Kit & 220V extension Kit available.

Nuheat Custom Mats can be purchased with whatever lead length is required or we can special order you a longer lead on a standard mat for approx $8 per Foot

Can I install Nuheat Floor Heating Mats upside down?

Yes and No. There is no up or down. Either side can be up or down, so you cannot do it wrong.

Is Nuheat radiant floor heating safe?

Absolutely! Nuheat Mats are built to ensure your safety! Nuheat’s innovative design encapsulates every wire within the mat in two layers of insulation; the standard plastic insulation that all wires are required to have and an additional outer braid of Stainless Steel. The braid works to protect the wires from being penetrated by sharp objects and also acts as the ground wire in the event of damage.

Nuheat is UL Listed (Underwriter’s Laboratory) and CSA Certified (Canadian Standards Association). This means that the product has undergone numerous rigorous tests to obtain a quality and safety stamp of approval. Use our programmable floor heating thermostats with built-in GFCI protection for the ultimate in safety, energy savings and convenience.

UL Listing is E154215. CSA File Number is LR76501-1

What does GFCI mean?

Ground Fault Circuit Interrupter. This safety device terminates the electrical power to the radiant heat system immediately in the event of damage to a wire or another catastrophe. A GFCI is required by electric code for floor heating applications, just like it’s required in most North American bathroom outlets. We always recommend one of our floor heat sensing Thermostats with its built-in GFCI protection.

Does Nuheat require a special GFCI Circuit Breaker?

Not as long as you use one of our Thermostat’s with GFCI protection built-in; then a regular circuit breaker of proper amperage with available load is fine. If contractors or relays are used, your installation will require additional protection – Check with your electrician to ensure the installation is done according to all applicable codes and all installation instructions are followed.

How much does Nuheat cost to operate?

Nuheat is an economical floor heating system. For example, a 25 square foot heated area of Nuheat will use only about the same amount of electricity as three 100-watt light bulbs. You will reduce energy costs even further by using our energy efficient programmable thermostat.

How do I operate Nuheat Floor Heating?

Nuheat requires a line voltage thermostat different from an HVAC thermostat, which operates at 24v. There are three thermostat options for controlling your Nuheat electric floor heating system and all include 5mA Class A GFCIs built-in for your safety:

• Harmony Programmable Thermostat. Using the very latest technology, this energy efficient 7-day Programmable In Floor Heat Sensing Thermostat mounts flush within the wall and can be fitted with any decora-style faceplate. The Harmony Thermostat requires a double gang box (2 positions) or can be combined with other switches in a multigang box.
• SOLO Programmable Thermostat. An Energy Star qualified 7-day Programmable Floor temperature sensing Thermostat for the Nuheat mats. Programmable means you can set up to 2 on and 2 off times per day customized to your schedule.
• TEMPO is a Non-programmable alternative for the Nuheat electric floor heating system. An LCD display with few buttons for easy manual control with GFCI protection.

All thermostat options for the Nuheat electric floor heating system are CSA certified, come complete with a built-in Class A G.F.C.I. and are available in 120 and 240 Volt formats.

Can I remove a tile installed over Nuheat Mats?
