You can operate KEMF heated mats manually by plugging them in when snow begins with a GFCI power unit, but automatic snow sensors eliminate the need to monitor weather and physically go outside. Snow sensors detect both snowfall and temperature drops, activating mats automatically when conditions require it. This reduces electricity costs by running mats only during snow events rather than leaving them on throughout winter. Snow sensors are available in both 120V and 240V versions and can be hardwired into your electrical circuit by a certified electrician.

KEMF extension cords feature watertight screw-lock connectors specifically designed to match the male and female connectors on KEMF heated mats. Standard household extension cords lack these weatherproof connectors and aren't rated for continuous outdoor winter exposure to snow, ice, and moisture. KEMF extension cords are available in 20-inch and 40 inches lengths for short connections between daisy-chained mats, plus 1-foot to 40-foot options or custom length of extension cord as required for reaching distant outlets. Both 120V and 240V versions are available voltage must match your mat system.

Yes, one GFCI (Ground Fault Circuit Interrupter) is required with every KEMF heated mat installation for safety. KEMF offers GFCI power units in 120V (with 6-foot cord) and 240V (with 6-foot cord) configurations. Each GFCI unit supports up to 15 amps total load, which means you can connect multiple mats to a single GFCI if combined amperage doesn't exceed 15 amps. For example, on a 120V system, one GFCI can power up to 16 HOTstars stair mats, 6 HOTstars door mats, 6 HOTstars passageway mats, or 4 HOTstars walkway mats or 2 HOTstars XL walkway mats.

No, voltage must match across your entire system. A 120V mat cannot plug into a 240V receptacle, and a 240V mat cannot plug into a 120V receptacle. This applies to all accessories including extension cords, GFCI units, and snow sensors. When ordering accessories, confirm your mat system voltage first. If you're unsure, check the label on your existing mats or contact KEMF at info@kemf.ca before purchasing accessories.

Remote controls (also called "power remotes") allow you to turn heated mats on and off from inside your home or building without going outside in winter weather. This is particularly useful for businesses that want staff to control mats from reception areas, or homeowners who want to activate mats before leaving for work. Remote controls work at a distance and can be combined with other control methods like snow sensors or hardwired switches installed by electricians.

Cable protectors shield the power cords connecting your heated mats from weather damage caused by rain, snow, and ice accumulation. They're particularly important in high-traffic areas where cords cross walkways or driveways, or in locations with heavy snowfall where ice buildup could damage unprotected cables. Cable protectors maintain consistent power delivery by preventing weather-related interruptions that could leave mats non-functional during snow events.

Yes, KEMF heated mats are designed with male and female connectors specifically for daisy-chaining. You can connect same or different types of mats together using the watertight screw connectors. However, total amperage must never exceed 15 amps on a single circuit. Use 20-inch or 40 inches extension cords for short connections between adjacent mats, or longer 5-foot to 40-foot extension cords when spanning greater distances. Always ensure voltage matches across all connected components.
