RADIANT FLOOR HEAT

Radiant floor heating can provide one of the most comfortable methods to heat a home. Fluid, heated from a power source like the CombiCor, circulates throughout the house radiating heat to the home.

This type of system:
Eliminates the need for heating vents and ducts in the home
Provides a very comfortable even temperature
 Rooms with vaulted ceilings are heated more efficiently because the heat stays near to the floor, not the ceiling.
Can melt snow on your driveway.
