Hot Carpet Woo Warmer Under Rug Radiant Floor Heater Electric Mat Electric Carpet Electric Heated Area Rug Great for Yoga (500 watt 70" x 70 inches) Made in Seattle Since 2012 A Unique Holiday Gift

I live in New England, and my condo is on the ground floor right over my building’s subterranean garage. New England winters can get bitterly cold, and no amount of insulation--both built in to the floors and supplemented with area rugs--can stop my floors from becoming absolutely frigid. In the winter, there can be more than a 10 degree temperature difference between my ceilings and my floors. I tried to solve my cold floor problem by setting up fans to circulate the warm air down to the ground, but this did nothing to raise the floor temperature. In fact, the warm air ended up being cooled by the floors rather than the floors being warmed by the air. And not only was it noisy with the fans going, it also ended up increasing my heating bill. Turns out circulating the air turned the floor into a heat sink. I tried space heaters, but that was like running a 1500W hair dryer in the middle of the floor. Most of the heat went straight up, and the point-source couldn’t distribute the heat around the room very well. Heaters installed directly into the floors would be nice, but that would be thousands upon thousands of dollars to tear up the floors and install them. I stumbled onto these Hot Carpet rug warmers almost by accident, but I decided to give one a try. I sandwiched one between my rug and a rug pad on the bottom, and it worked perfectly and solved my cold floor problem immediately! With the source of heat at the lowest point in the room, it’s a barrier against the cold floor with everything above it maintained at a comfortable temperature. And because the heat is spread out over a wide area, the heat is distributed more evenly throughout the room. It worked so well, I bought two more 500W models! And even though running three rug warmers uses 1500W of electricity, my total energy bill ends up being lower. The cost of using that electricity to provide heat directly at the floor level saves the central heat from having to work as hard and ends up being both more efficient and more effective. I connect my rug warmers to smart plugs, which allows me to turn them on with a voice command for Siri/Alexa/Google and also allows for programming an automatic on/off schedule. This also allows me to position the control units under the couch or in locations that are hard to reach but also out of sight. On a final note, the company’s customer service is fantastic. The few occasions I’ve had to contact them, they’ve responded immediately and resolved my issues quickly and completely. They stand behind their product 100%. (You can find their contact info on their website.) If you’ve got a situation like mine, I highly recommend these rug warmers!

It's pretty nice for slab on grade floors, keeps feet warm under my living room rug. I would highly recommend getting some thick felt to lift the rest of the rug to the same level. That will help with vacuuming. I wish they made larger sizes. The power box is kinda thick and it's hard to position somewhere out of the way. If you have an outlet on a switch that makes it a lot easier to use because you can set it the way you like and then turn it on and off with the switch. You could also use one of those wifi switches. If you can position it right for the zones to be useful it's a great feature, but if not it's useless. The heating elements don't go to the edges equally. That's a lot of complaints but it is really nice and does what it's supposed to. Just takes a bit of fiddling.

I like to sit on the floor sometimes. To browse the internet, or play a video game, with a bunch of pillows and blankets, maybe a bowl of popcorn. We got this to make a sort of cozy, kotatsu-style space for sitting on the floor. We put the woo-warmer under a wool rug that we had and turn it on for cold winter movie nights. So, so cozy. I'm in love with this thing. The settings give you good options for how much heat and where it should be. If you're worried it won't get warm enough, I've found that if I crank it all the way up it can actually get uncomfortably warm, even through a thick carpet. Not enough to burn or melt anything, just more than you want to be laying on. The slider for selecting your heat level is therefore very helpful. On the coldest nights, 60-70% power has been perfect. This has been so great next to our fireplace. Even though we don't have a fire going for safety reasons, you still get the warm cozy feeling of a fireplace when you sit on the warm carpet. Great also with a low table for sitting to get some work done or play cards with the kiddo. I hope it lasts a good long time.

It's a good size and good feel but it doesn't warm up well. Even after being on for 3 hours, it's barely above the room temperature. It claims to warm up to 115F but it doesn't get anywhere near that. Barely reaching 80F in a room that's 70F. Not worth the price for that result.

Arrived not turning on or working at all. Probably a one off and I did get a refund but had it cost me a lot for the international shipping and return. Such a shame as this looks like a fantastic product. I couldn’t take the risk of ordering a replacement.

I live in an older home with no insulation under the floor. I had a carpet pad and carpet but my feet would still be cold. Adding the Hot Carpet was a nice addition to keeping warm on cold winter nights. It warms quickly. My updated wishes include the ability to heat the entire carpet and not just the left or right zine. I also hope the item can be redesigned to be more aligned with standard carpet sizes like 4x6 or 5x7.

I normally don't leave reviews, but I had to because the customer service is fantastic. I first experienced heated floors when visiting a friend in Korea, they are really nice, makes energy more efficient, so when I had problems with my cold hardwood floors in my NYC apartment I was looking for something like this. It worked great and I was really happy with this product since it was helping A LOT (not super hot but very comfortable). Unfortunately it broke less than a year into it, and I contacted the company about fixing or replacing it. WOW! They are so responsive. I would give this 11 stars if I could, 5 for product and 6 for the company.

This mat worked fine, but it uses a lot of electricity!! On the Amazon website it claims, "...to use pennies a day". This, I think, is far from fact... and I just wanted to add that information for future buyers.
