Adding Heat To the Project is Simple

FeelsWarm Heaters can be stuck onto the underside of the stone (Stick-On) or they can quickly be stuck down on a support substrate as shown (NL Models)  before the countertop is placed.

Stick-On Heaters
NL Compressed Heaters
FeelsWarm heaters can be installed by professional contractors or by homeowners with a basic level of "handyman" skills.    
Typically, contractors are involved with new countertop installations, however since stick-on heaters are also used for existing countertop overhangs, homeowners may elect to install the heater themselves.
