The Nuheat 120V Cable System (N1C040) provides comfortable, consistent radiant heat across up to 40 sq. ft. of floor space, making it an ideal choice for warming bathrooms, kitchens, and other indoor spaces. Unlike a pre-built mat, the heating cable is installed loose across the subfloor at a set spacing, giving installers the flexibility to route it around toilets, vanities, and other fixtures to fit rooms a fixed-size mat can't match.

The Nuheat 120V Cable System (N1C040) provides comfortable, consistent radiant heat across up to 40 sq. ft. of floor space, making it an ideal choice for warming bathrooms, laundry rooms, and other indoor spaces. Unlike a pre-built mat, the heating cable is installed loose across the subfloor at a set spacing, giving installers the flexibility to route it around toilets, vanities, and other fixtures to fit rooms a fixed-size mat can't match.

The 148 ft. cable is manufactured to work with this kit's coverage and spacing, so it should not be cut, shortened, or modified during installation.

Key Features

Custom-Fit Cable Layout

Because the cable installs loose rather than on a pre-built backing, it can be routed around fixtures and into irregularly shaped rooms, offering more layout flexibility than a fixed-size mat.

Membrane-Ready Installation

The cable is secured in place at a consistent spacing using a heat membrane or fixing strips, keeping the heating pattern even before thinset and flooring go down.

Consistent Radiant Heat

The Nuheat Cable System delivers 12 watts per square foot for reliable, evenly distributed warmth throughout the heated area. At 40 sq. ft., the N1C040 draws 442 watts (3.7 amps) at 120V.

Easy Installation

The cable is designed to be secured directly to the prepared subfloor and covered with thinset, allowing tile, stone, or concrete flooring to be installed directly over the heating system.

Installation Notes: Install the cable at its full factory length with at least 3 inches between runs. Secure it with a heat membrane or fixing strips before applying thinset. A dedicated GFCI-protected circuit is required, and cable resistance should be tested before, during, and after installation. Electrical connections must be completed by a certified electrician.

Nuheat Electric Floor Heating Cable System FAQ

How do I choose the right size cable kit?

Choose a kit based on the actual area you want to heat rather than the total room size. Permanent fixtures and areas that don't require floor heating should be excluded when determining the coverage needed. Each cable kit is manufactured to a fixed length matched to its rated coverage at standard spacing, so measure carefully before ordering.

For assistance choosing the right size before purchasing, the Plumbing Deals team can help when you use the live chat feature, email at contact@plumbingdeals.com, or give us a call at 888-682-5956!

Can the Nuheat cable be cut or shortened to fit my room?

No. The cable cannot be cut, shortened, spliced, overlapped, or otherwise modified. Instead, the loose cable is routed back and forth across the heated area at the required spacing, which gives it more flexibility to fit around fixtures and into irregular layouts than a fixed-size mat. If a room's shape or size doesn't match any standard kit, Nuheat offers custom cable systems built to the dimensions of the space.

What flooring can be installed over a Nuheat Cable System?

Nuheat Cable Systems are designed for embedded indoor floor heating and are commonly installed beneath tile, natural stone, and concrete flooring. The cable is secured to the subfloor with a heat membrane or fixing strips and covered with thinset before the finished flooring is installed according to the flooring manufacturer's requirements.

Will Nuheat floor heating replace my furnace or central heating system?

For most homes, Nuheat is used as supplemental, room-by-room heat rather than a whole-house replacement. It lets you turn down the central thermostat while keeping specific rooms, like a bathroom or kitchen, comfortable underfoot. In a well-insulated, modern room, it can serve as the primary heat source on its own; in an older or less-insulated space, it's best paired with your existing heating system.

How soon can I turn the floor heating on after installation?

Not until the thinset or mortar over the mat has fully cured. Follow the cure time listed by your setting compound's manufacturer, since it varies by product and site conditions. Turning the system on too early can cause the mortar to fail or the grout to crack, and may void the flooring product's warranty.
