ThermoSlab Storage Heating System consists of heating cables installed in the foundation of a building either in the concrete slab, or in the sand bed below the concrete slab.

It comes with the following features and benefits:

  • Provides slab storage heating in new construction or when pouring a new slab.
  • Allows for taking advantage of off-peak electricity rates where applicable.
  • Once heavy duty cables are imbedded in the slab, any type of floor covering can be installed or changed in the future without damaging the floor heat system.
  • The 20’ factory-attached lead wire on only one end of the heat cable facilitates the electrical connection.
  • Dual cable construction virtually eliminates electro-magnetic field and interference with electronic appliances.
  • Listed in compliance with UL Standards for the U.S. and Canada.
  • Factory-direct prices and support.

Versatile and easy to install, ThermoSlab storage heating system is the optimal way to heat residential or commercial buildings!
