Over 100sqft kitchen

There is 108sqft of heating area in the remodeling kitchen project. HeatTech heating system was chosen as secondary source of heat and will be installed on top the plywood under marble floor. There is heating vent (12"x3") and its center is 16" from "patio door" and 90" from "door" on the left side. All dimensions are in inches.
Heating mat 20" wide x 54.9ft long was chosen as the best coverage for the heating area. 8" was kept from all sides of heating vent, as it's the minimal clearance from all heating appliances and 1-4" from the walls.
The best option for the kitchen project is HTMATKIT-120-90
