  • Warmzone In-Slab Radiant Floor Heating - Warmzone In-Slab floor heating systems are an inexpensive and effective way to heat your floors. The In-Slab heat cable is required to be embedded in minimum of 1/2-inch in concrete or mortar. Using a self-leveling material can make this part of the install easier. Any type of flooring can be installed on top of the base layer of the In-Slab radiant floor heating system. This method of floor heating requires a little more labor for the installation, but it can save you a few dollars per square foot on certain sized areas - and it's one of the best quality floor heating systems on the market.

  • RetroHeat Under Floor Heating - The RetroHeat system is the optimal solution for installing radiant heating under existing floors. The floor heating panels for this system are stapled-up underneath the floor joists. This system can provide enough heat for entire rooms or supplemental floor heat under any flooring.
