DS-9C-DP Snow Melting Mat Pre-Assemble Snow / Controller With 10 Feet Sensor Cable

The standard spacing for installation with uncoupling membrane is 3 slots and installing with floor guides it is 4 inches.

Yes, all of our kits include 2 floor sensors. One kit is for back up.

No, the membrane is not included in the package because the quantity of the membrane is not equal to the heated area.

The regular membrane requires adhesive and must dry before installing the heating cable, while the pre-glued membrane allows for immediate installation of the cable. Both types will be adhered, but the pre-glued option simplifies the process by eliminating the wait time for drying.

The membrane is 1/4 Inch or 6mm in thickness.

Yes, all of our thermostat have GFCI protection

Not necessarily. Voltage alone does not determine power.

A 240V cable can carry more power than a 120V cable if the current (amperage) is the same. For example:

• A 120V, 10A circuit delivers 1,200 watts (120×10120×10).
• A 240V, 10A circuit delivers 2,400 watts (240×10240×10).

Why Use 240V?

• At the same power level, 240V requires half the current of a 120V system, meaning thinner wires can be used, reducing energy losses due to resistance.

So, a 240V system can be more "powerful" if used correctly, but it depends on the current as well.

No, just different sizes
