I just received my RugBuddy 5×7, and it is great.  I have it in my basement, over the wall-to-wall and under an area rug.

I want to leave it on full-time until Spring; Is there any reason I can’t do this?  For example, should I worry about overheating?

Speedheat’s Answer:

Hi Paul,

I am so glad to hear that you are enjoying your RugBuddy!  You can absolutely leave it on all the time.  The heater is self-regulating, so it will not overheat.

All Speedheat electric radiant floor heating systems are completely safe and waterproof. Whether under carpet, area rugs, vinyl, tile, stone, hardwood, laminate, showers, and more, all systems are completely safe.
Technically put…

The electrically insulating polymeric sheath is conveniently formed from a polytetrafluoroethylene (PTFE) compound.

The PTFE layer effectively protects the core. If overheating of the core occurred, the electrical insulating properties of the PTFE would decrease, or the PTFE sheath would melt, thereby causing leakage to the ground shield. Power would thus be tripped out long before the surface temperature of the ground shield could increase to a point, where it is dangerous.

As a result, a simple ground fault interrupter device would adequately protect an under-carpet heating system, which employed the cable of the invention, against risk of fire and shock.
