In-Slab Heat Cable

Warmzone's In-Slab heat cable is a durable, high quality heating cable that can be installed to provide luxurious radiant floor heating for virtually any type of home or commercial floor surface. The In-Slab heat cable is popular because it is a very rugged cable that is extremely efficient as well as versatile.


Warmzone In-Slab heat cable (also known as Warmzone SlabHeat) has a protective metallic shield and is waterproof, so it is safe for use in both wet and dry applications. Designed to produce 10-15 watts per square foot, In-Slab heat cable is the premier radiant floor heating solution for in-slab applications in both small, custom residential as well as large commercial radiant heating projects. The floor heating system efficiently provides comfortable heat for virtually every floor type and heating application.


The radiant floor heating system is controlled by a technologically advanced, easy-to-use thermostat with a built-in GFCI and in-floor sensor. The programmable thermostat features a clock function that allows you to set four events per day as well as weekday and weekend settings. The floor heating system can be programmed so that your floors are warmed just prior to you getting up in the morning and then shutting off as you leave for work. The programmable feature allows you to efficiently use the radiant heat system precisely when you need. You can also temporarily change the temperature for a single event with the programmable thermostat. After doing so, the floor heating system will return to the program schedule on the next scheduled event.


Another advantage of the Warmzone In-Slab electric floor heating system is that the heat cable warms your floors quickly and evenly. Unlike some systems that take considerable time to heat up the floor, the electric In-Slab system has a fast response time, which also adds to the efficiency of the system by requiring less operating time.


Energy efficient, maintenance free, and easy to use, the Warmzone In-Slab radiant floor heating system is the system of choice for applications requiring the cable to be embedded in the concrete floor slab.
