MasterHeat Wire is a simple, economical way to warm floors and provide years of lasting comfort. Warm all kinds of floor coverings: ceramic tile, stone, wood, laminates, vinyl, or carpet. There’s a MasterHeat spool sized for your project. Lay out and attach the MasterHeat strap. Fasten the MasterHeat to the strap as you weave it back and forth across the floor. Put down a layer of thin-set mortar and set your tile or stone, or install a layer of self-leveling cement over the cables for hardwood, laminate, vinyl, or carpeted floors. Our installation manual will show all the details.

Kitchen/breakfast Layout

Due to differences in heat loss between the kitchen and breakfast areas, two different spacings were used: 3” on center in the kitchen, and 2” on center in the breakfast area due to the higher heat loss.

MasterHeat Wire is easily sized for any project.

• Evaluate how many square feet of floor are to be heated. Do not put under cabinets or appliances. Generally, about 85–90% of the open areas should be heated. Leave the wire at least 4” away from the toilet wax ring and 4”–6” away from your walls. To keep toes warm, install right up to the toe-kick in front of kitchen or bath cabinets, and in front of a toilet, shower, or tub.
• Choose a “spacing factor” of 2”, 2-1/2”, or 3” on center. Below are guidelines for application and spacing recommendations.

• 2” on center=15 Watts/sq.ft.
Use on concrete basement slabs, sunrooms, and in other high heat loss areas.
• 2-1/2” on center=12 Watts/sq.ft.
Use in bathrooms, kitchens, dining/living areas, etc.
• 3” on center=10 Watts/sq.ft.
Use in hallways, entries, low heat loss areas, etc.
2-1/2” on center is the most commonly used spacing, and equals the heat output of MasterHeat mats.
