SunTouch SlabHeat Cables are the best solution for true radiant floor heating installed within a new concrete slab pour.
SlabHeat is engineered by the world leader in electric floor heating systems with the capability to produce enough BTUs to heat a slab, the space, and the surface people walk on. Regardless of size, shape, or thickness, SlabHeat is the way to provide heat to just about any indoor space.
Benefits of SlabHeat
Tough polyurethane outer jacket offers superior flexibility, abrasion and tear resistance, impact resistance, resiliency and better low temperature stability than the PVC used in competing products.

- Engineered by Watts Radiant SunTouch a company with decades of experience in hydronic and electric radiant heating
- Comfortable, even heat without the drying effects of forced air heating
- Reliable, durable design
- No vents or duct work
- Invisible with no lost space - not like large intrusive base board heaters
- Maintenance-free and silent
- Efficient radiant heat of up to 51 BTUs per Sq Ft
SlabHeat Cable is a complete heating cable consisting of a series resistance heating cable and a single power lead for easy single point connection. The heating cable length cannot be cut to fit. Constant wattage output is approximately 5 Watts per Linear Foot.
SlabHeat cable should be installed in all interior floor areas to be warmed. It cannot be used for exterior applications, snow melting, or in ceilings.
Primary Heat Applications
A properly designed heating system begins with an accurate heat-loss calculation to determine whether the system will provide enough energy to function as the primary heat source for the space or provide floor warming only. If it is a primary heating system, we recommend a detailed heat-loss be performed first, then select wire spacing based on heat output. If you have already know the BTUs required, the calculation is simple. If you need us to perform a heat-loss calculation, please download the form and return it to us with all details completed.
