  • Straight forward installation and efficiently heats floor and air
  • June 29, 2016
  • Recommended Product

This is basically a toaster that you put under your floor. It's a resistance 120v AC system that you can control with a timer, thermostat, or an on/off switch. It is incredibly thin yet effective There is an installation video on the Home Depot website that does a fantastic job of illustrating the installation process so I will not go into that here. Watch and understand the video. It is very useful I used this under a floating laminate floor in a basement over concrete floors. Once installed, I have found a few things. The floor does not heat up quickly. It took probably 20 minutes to get it up to full temperature. The air temperature in the room also does not heat up immediately. I found that the air temp went from 67 to 73 in about 30 minutes with the floor at 96 degrees F. There is some inconsistency in the heat too on the floor. There are hot spots and warm spots as shown in the photos. I know resistance heat can be vary so I do not feel this is a deal breaker. Overall, this is an great solution to cold floors especially in a basement that not only heats your feet but air as well. I would classify this as an advanced DIY job

Pros Comfortable, heats air and floor Cons some inconsistencies in heat

Just in time for our new wood floor in our walk in closet. The product was easy to install but you do need lots of planning. The actual install was fast but you do need to read and understand the electrical,requirements that will also go through a thermostat not included . First you need a 20 amp circuit that is not shared. Then you need to get the wires to the radiant heat film. Remember this is Radiant heat film and is not instant heat it could take from hours to days to get your floor area up to your desired temperature . Depending on the sub floor and the floor finish will determine the amount of time . Radiant heat takes a while for things to absorb the energy the air in most cases may never reach your desired temp. It is also something you don't turn off and i.e. peck it ti cool quickly. So great product made well with high quality products. Not a beginner project but can be done , read the instructions and hire an electrician if electric is not your thing.

Pros Durable, Easy to Install, Easy to Use, High Quality

We put in place 2, 3' x 10' films in our 9' x 15' three season room under new laminate planks. Floating floor. Ran a dedicated GFI line to the electrical panel. Had the thermostat set to 75. Turned it on and after 5 minutes, we read the temperature with a thermal reader which measured 80 degrees! For now, we set the schedule to one of the manufacturers presets. A couple of hours in the morning, off for the afternoon and on again in the early evening. Great product. It can be laid either side up. We set it curl side down and it happened to have all the labels and print reading right side up. Directions are easy to follow. We had an electrician finish and connect the wiring.

This is a fairly easy to install system. It's super thin so it doesn't add any thickness to the floor. The wires that run from the underlayment to the thermostat are thicker than the underlayment itself. The only surprise here is that the type of thermostat you need for this is pretty expensive. You can't use a standard thermostat. One other thing to note is the temperature you set on the thermostat adjusts the "floor" temp and not the "room" temp. This type of system isn't designed to actually heat up the room, just the floor. However there is some added warmth to the room but you can't rely on this alone for your heat, at least not in a fairly cold climate. But a great system overall.

  • Easy to install, but requires some planning. Paper-thin and adds no discernable thickness to floor. Works well to warm an area of flooring.
  • June 30, 2015

This product installs easily under floating laminate, engineered hardwood flooring, and carpeting, but is not recommended for flooring that is nailed down because the nails can damage the heating elements and interrupt the flow of power. At a thickness of less than 1/16-inch, this product is ultra-thin and does therefore not add any discernable thickness or sponginess to the finished flooring. The provided 30 sq. ft. (3-ft x 10-ft roll) isn’t a lot of area coverage, but is sufficient to run along the front of a bathroom vanity or bedside, to take the chill off your feet when you first step onto the flooring. Multiple rolls of the product can be spliced together to cover a larger area. To install, a bit of planning is required since you need to connect to a power source, such as a nearby 120V electrical wall receptacle, and a thermostat. MP Model #THERMST thermostat, available at The Home Depot (SKU #238472), is recommended for this heated underlayment because, unlike a traditional thermostat, it features a floor sensor that monitors temperature of the heated floor. The product is installed the same as you would underlayment, and the length can be trimmed with a sharp knife or scissors, and taped securely into place, prior to installation of the flooring. To allow for wiring, and not add unusual thickness and bulges to areas of the flooring, it may be necessary to cut out sections and strips of the underlayment to provide pockets and channels for the wires to run. Overall, a good product, but warming a large area, such as a bedroom, where multiple rolls are needed, can be costly. There are other products available that incorporate a heating element into the underlayment, but they are more costly and don’t work as well to warm the floor as the QuietWarmth heated underlayment, which is installed on top of the underlayment, directly below the flooring. Great solution to cold flooring. Highly recommended.

  • Perfect for the bathroom floor

This was a very needed thing for my bathroom floor. I have always wanted some kind of added heat in my bathroom. When I get out of the shower I am a little cold. This mat goes under the flooring material. I ended up putting it underneath tile. I had carpet in the bathroom that I removed. I used a new material from HomeDepot model#DH5MA to separate this from the tile above it. The hard part was finding where to put the wires. What I ended up doing is just drilling through the floor near the wired end of the heat strip. Then I ran the wires to a junction box under the floor. From there I ran the wires to a control box. I would say the worst part was finding out how expensive the control thermostat and temperature probes (thermocouples) were. What I ended up using was off the shelf controller from China for $21.49 and used a K type thermocouple for $2.49.

Pros High Quality of Material, Comfortable, Easy to Install, Modern, Effective Cons thermostat controller cost too much!

My home office is in an annexed sunroom. It is very cold in the winter. I am going to use this underneath a thin sheet of plywood - like a chair mat. It should provide supplemental warmth. The temperature profile from floor radiant heat is warmer nearer to the floor. This is different from forced air heat where the heat goes straight up. More people would be able to use this hack than those who would use the film in a new construction.

Pros Easy to Clean, Easy to Install, Easy to Use, Good Size & Weight, Lots of Features, Nice Design, Sturdy

Had to join two completely floors together in a threshold. We were able to join the two almost perfectly without raising the new floor overall height and gaining warm floors to boot! Bonus feature was we had to cut 4 inches off of the heated mat to make it fit, works great.

Pros Comfortable, Effective

  • easy to install floor warmth
  • December 23, 2014

This 6 watt/square foot electric radiant warming film was easy to install beneath floating engineered flooring. The lower wattage was perfect for warning the floor and secondary heat for a chilly bedroom. The lower amperage requirement (vs typical 12 watt/square foot) eliminated the need to upgrade the electrical feed to the room. This is a good product for supplemental heat (or possibly primary heat in a very well insulated room) and just what was needed for my installation.

  • Nice warm floors.

I installed this in a breakfast nook that I built in what was a sun porch. Well it is well insulated as part of the conversion, it has an unheated crawl space under it. So I wanted something to keep the floor warm on my bear feet! Installation is easy. You can cut it to length by cutting on the dashed line closest to the length you need. You then cover the ends of the power buss with the supplied insulating circles supplied. This was great for me because my space was only 7 feet long. You then tape it too the sub-floor, making sure you will not be driving screws or nails through it! The hardest part is getting the power wires from the sub-floor and into the wall. You need to make provisions for this before closing up the wall. You also need to make provisions for the sensor cable from the thermostat. You need to sense the temperature under the floor - not the room temperature. So make sure you get one designed for this type of heating. Well it is hard to tell how well it is going to work in summer weather, it does get the floor comfortably warm. I will find out this winter if I need to add more heat, and how expensive it is to run. I did make provisions to add more heat to the nook if needed.

Pros High Quality of Material, Great Instructions, Easy to Install Cons required a special thermostate.
