Float QWARM3x5F120 Radiant Floor Heat for below Laminate, Wood, LV Floating Floors- Cuttable Mat Size 3'x5' 120V

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.

I put the wired heat in the master bath floor, nice warm, Pain to do, embed in mortar etc. This tape it on the floor and route the wires, OMG it was so much easier. I just put this on a switch, heats up the floor pretty quickly, it;s in the guest suite bath so company coming, flip the switch. Easy inexpensive and ... this is the only way I would do it in the future, that said let's see how it holds up, keeps working.

So far so good. My husband installed it and Happy with it.

I cannot get this to heat up. I have tested the power and it everything is working. Thermostat, probe, and the mat have electricity running properly. Thermostat and probe are working. Mat is not heating up. Could use some assistance or replacement.

working great

Only fair heating of floor and no heating Of room. Expensive installation.

I had to return one of the 2 because I didn’t read close enough. It’s for floating floor only so I had to send one back and get the one for under tile. That was my mistake that these are very nice mats, and would highly recommend.

Cons: Does not work for concrete basement floors. I tested in the spring when it has been 80-90 degrees for a couple of months. This mat is not strong enough to warm up the concrete floor even during the warm times of the year let alone winter. I wish they would have made that clear in the description. Would have saved me a lot of time and money. That is why I dropped the review to 3 stars. Hopefully this works for other areas of the house.Pros: Great support. They really tried to test everything possible that could be wrong with the installation. Much appreciated. That's why this mat gets 3 stars.
