QuietWarmth Float QWARM3X10F120 Radiant Floor Heating Mat for Below Laminate, Wood, Luxury Vinyl Floating Flooring- Cuttable Mat Size 3'x10' 120 Volt (Covers 30sf)

This floor heating system is absolutely perfect. It’s easy to install and works great on a concrete slab floor in our Nebraska home. I found it easiest to lay it out on the concrete slab and mark the routing of the wires and 2 filament contact pads, then I used a Rotozip with a burring bit to grind out grooves for wiring to ensure nothing was pinched under the flooring. I went with the QuietWarmth LV underlayment, WiFi thermostat, and Mohawk luxury vinyl planks (Costco). We couldn’t be happier with how well this product works.

Absolutely five stars, ten if it were possible. The ambient heat keeps my entire bathroom cozy all winter long if I leave it on a low setting. Was very easy to install, high quality, and so far it's very durable. We installed it last fall and it's been over a year now and I would definitely recommend if this is something you've been considering.

I like this product. I've had just over 1 sq-m installed under a floating cork floor in a small basement bathroom for two years now. The panels cover about 1/3 of the floor, the rest is sink and toilet. The printed panels provide a much more even heat than the wired ones. However, they don't provide *significant* heat. The spec is 12W per sq-ft. So for my roughly 11 sq=ft I can expect about 130W max. That's two incandescent light bulbs worth of heat. Imagine how warm your bathroom will feel if you leave two light bulbs on overnight - not very... The issue is that older floating floors could not take the heat. Now they can. Ideally QuietWarmth will come out with a panel that puts out closer to 25W/sq-ft. Still, our floor is much warmer than it used to be. I used insulating underlayment across the entire floor. With the panels on 24-7 the floor hits 20C. (To those of you in the third world that's about 68 Freedom Degrees). It's nice on bare feet when you step out of the shower. Last thing, I was foolish enough to buy an expensive temperature sensing controller. Don't do it. A simple light switch is all you need. I keep the floor on during the winter and off during the summer.

Easy to install, good instructions. The only thing - instructions say to leave a minimum of 6” between mats. I would go lower than that - like 3” instead - I can feel cold strips between them on our LVP floor. It’s less noticeable when the HVAC is warmer, but mildly disappointing. We also used the Sun Touch thermostat (more modern interface). Worked fine even if unofficial.

Installed 4 pads under 1/2" engineered hardwood floating flooring. Routing the wires inside grooves cut in underlayment took the longest (an hour for me). I installed a metal wire-protecting cover where the wiring entered the wall at the sole plate (see pic). I ran the sensor wire out of the same hole in the sole plate, and have had no issues in the 2 months since installation. Recommend you cover the pads with cardboard while working on the remaining flooring, and check the impedance frequently during installation. I did it 4 times. UPDATE: 1 year since install. Works perfectly. Added 4 similar pads to attic bedroom (under the same engineered flooring). Cut wider grooves in the pad to lay 6 wires side-by-side, then covered them completely with duct tape to prevent shifting. Electrical inspector required me to use 2 separate conduits from thermostat box to the base plate of the wall. I installed 2 sensors. VERY pleased with the results in both rooms! I did some testing over a few days and found that these pads don't warm the air temperature more than 2-3 degrees, but they are a game-changer to making our rooms more comfortable in the tough Winters in Minnesota. Will be helping my neighbor install 8 240v pads in his basement next weekend.

Self-I stalled on two separate floor installations. Still working five years later.

This product was easy to install and seemed wonderful to start. Soon we noticed the floor getting hotter and hotter even after turning the temperature down. Then it just quit working and doesn't heat at all. Incredibly frustrating that we will have to take everything out - baseboards, cabinets, furniture and flooring in a brand new designed room to take these out and find a new solution.

I like the efficiency of this, I use it as a portable floor heater. It’s great for warming shoes, and for my dogs bed. I like this brand of heat strip. It’s warm from edge to edge, end to end. No cold spots. It’s between a piece of OSB with laminate on top. I like that it does not heat hot the temperature is warm to bare feet I like that. I’m planning on purchasing a longer length for use on my camper floor, with new laminate on top. I highly recommend.

Works as advertised.

Perfect for my small galley kitchen.. only required two 10 ft rolls.. side by side.. takes the chill off the floor! Ensure your vinyl flooring is a minimum of 2mm thickness!

If you are installing laminate flooring this is a great product easy install and works great

In instructions is does not tell you to set wattage on the thermostat and on thermostat it says not required. However at 100 watts it was not really working. When I put the wattage for both mats correctly at 750 it worked wonderfully.

First day, seemed to work. but second day, I smelled burning plastic smell, and the floor was too hot to even touch. The floor was literally melting and caused it to separate. The thermostat read it was only 3 degrees Celsius so it is either a malfunction with the mat, the sensor or the thermostat. Either way, I'm out thousands of dollars in flooring and labour time and I installed two of these mats and too scared to keep the other one in fear of burning down my home. I used LVT which manufacturer says is ok for this product. Brand new build.
