The SpeedheatÂ® electric radiant heating panel for under area rugs is the perfect space heater alternative for any cold space. ? RugBuddyTM plugs directly into a standard wall outlet and is protected by a GFCI plug, making it 100% safe. ? RugBuddy is even waterproof! ? The Speedheat ultra-thin, patented heating technology is less than 1/16th of an inch thick, so the only thing felt under foot is cozy warmth. With the RugBuddy, you can have electric radiant floor heating for a mere fraction of the cost of installed systems. Plus, at only 11-watts/square foot, the RugBuddy only costs 3-4 cents per hour to operate; making it the most cost effective solution for any cold space! NOTES: ? You MUST use a rug on top & a rug pad below. Follow instructions closely. ? For primary heating, cover 75-80% of open floor space. ? Simply place the extremely thin (less than 1/16") heater under your area rug and plug in. ? Can also be used with a timer or hard-wired with a thermostat. Safety assured by the IEC, radiant heating is also endorsed by the US Department of Energy.
